What Makes Deflector Shields Different?

[@aliboy357]

If I remember correctly, transporters also struggle when presented with too much EM interference, and it's likely that an additional level of defence used by starships is to produce an extra layer of EM interference when on a higher alert level to help prevent someone transporting through the shields even if they have the frequency.

[@mammutMK2]

Even if matching the frequency perfectly, let's say a phaser passing through would loose 1% of energy...if that hapens during a transport that will be bad. And i would even guess a small hole could open in the shield (or a guidance tunnel) to let a torpedo pass through in the moment of firing just to prevent damage to the torpedo.

Basically, you cannot just make the energy disappear, and they’re not reflecting it. That means they have to negate it. It would work on multiple frequencies and wavelengths. Opposing waves of energy will have to be calibrated and utilized. As they advance and gather data, subsets and basic systems will be created. An adaptive program/system will have to adjust on the fly and gather information for new modulations as different types of damage and energy are intercept by the shield barrier. Eventually we will discover a method that can encompass large amounts of different types, a certain type of modulation that will protect as needed while allowing freedom of movement and sight.

My understanding of the metaphasic shield was that it partially placed whatever it was shielding in subspace itself. Meaning that whatever might make it through the standard shields, even if it isn’t sufficiently deflected away, just has less ability to interact/damage the ship inside.

[@peccatumDei]

I was rather surprised when I learned that the NX-01 Enterprise had Transporters, but not shields. Compared to the Warp Drive, shields should be a fairly simple technology. Credit is again due to the writers of Enterprise, who elaborated on this technology when they showed it in it's infant form. Essentially, you have a thin sheet of particles (one assumes charged particles, i.e. plasma) suspended between a pair of fields. This part is simple enough. As far back as 1980, I remember seeing a loudspeaker that worked by suspending helium plasma between two magnetic fields. Modulating the fields caused the plasma sheet to vibrate, thus moving the air and creating the sound. The fiction part of all this is finding a particle that's a perfect energy conductor. What you definitely don't want, is a shield that absorbs energy. Such a shield would be overwhelmed in nanoseconds. Just as the space shuttle heat shield is made up of heat conductors that re-radiate the heat almost instantly, the shields in Star Trek would have to dump the energy directed at them very quickly. You would also need a particle that works across a wide range of frequencies, or a blend of particles to achieve the same result. In order to break through a shield, an enemy is forced to pump in energy at a high enough density that it destroys the particles, and does so at a faster rate than the target is capable of replacing them. By the way, I think there's room within physics for an entirely different shield technology, and not that multiphasic crap they came up with on TNG. I've named this new type a spawning shield, and the theory goes something like this: Hadrons (protons, neutrons, etc.) are subatomic particles made up out of quarks. (true science) Scientists can't produce isolated quarks, because the energy required to smash hadrons apart winds up as new quarks, which combine with the originals so that you just wind up with extra hadrons. (also true science) Now, IF you found a hadron that absorbed energy across a wide spectrum, they would make a very interesting shield. As energy is pumped in, the particles would break apart and spawn additional particles. Enemy fire would strengthen a shield, rather than weaken it. Indeed, the problem might very well become one of how to shed surplus particles fast enough.

[@cross3052]

Excellent idea.

[@VulpisFoxfire]

A thought on transporters vs. shields...possibly, transporting requires too wide a set of frequencies to 'fit' through the gaps in the shielding without degrading to a hazardous degree. Like putting your people through a strainer...

Interference in a transporter beam causing corruption to the data I imagine would be terrible for the thing being transported. Interference with an phaser may reduce the effectiveness but mostly that doesn't matter so much. So the SieveStrainer metaphor works well.

[@materialdialectics]

I'll just paste the comment I just made in here because now I'm curious what you think. Actually it kinda makes sense that we see beaming through shields less. Because with the whole refresh rate frequency idea, when it comes to energy weapons it doesn't really matter if 1% of the energy doesn't make it through due to slight inaccuracies in one's knowledge in what that frequency is and/or the accuracy of whatever is controlling/generating/regulating the frequency reference (like how a radio needs to have the oscillating frequency generator for reference to process the incoming information normally via the use of a crystal oscillator; I might be screwing that up slightly or oversimplifying). However with a transporter.... that 1% may very well be the difference between life and death for the person beaming through.

The problem with the “matching shield frequency to fire through” idea is it creates the plot hole in Star Trek Generations that when the Riker ordered Worf to return fire on the Duras sisters’ Bird of Prey the Enterprise’s phasers should’ve passed through its shields as easily as the BoP’s disruptor fire passed through the Enterprise’s…

[@dangeary2134]

How about something more serious, lol! I have a theory for artificial gravity on space ships. We already know of the Alcubierre formula, and it’s few iterations of the formula as described by the 3D model image. If the warp field is tuned for travel, the deep dip in front, and high apex in the rear of a ship, with the ship supposedly within the “ring” that describes the field. The second iteration that was put out had the inner section inside the warp “ring” at an angle that would have been more than adequate to be the “artificial gravity.” Follow me, it’s easy and hard all at once…. So, maintaining the lesser inertial forces inside the field was automatic. A ship at rest, or “full stop,” would have no warp ring, yet still be producing a gravity field for the crew. Smaller fields could be used within that field, as we have seen where lifters can move heavy items. So, your artificial gravity and inertial dampers are basically one and the same. As a side note, being tossed around in a ship would simply be a reaction to the system’s inability to compensate for some of the larger, or more intense, energy weapons that would drain the system for brief periods. In that case, floating down a corridor or being smashed to a wall or floor would not be that uncommon in a heavy battle. This all assumes we have no real source to generate gravitons. Or do we?? By placing a standing wave of multiple “warp rings” around a ship, and energizing each ring with its own frequency of ionizing energy within, these “force fields” would be a fairly easy task to create. My own theory is, we will be capable of producing a field that is able to surround a ship, but never be able to get one to hug a surface. Electromagnetic and gravitic forces are very happy to follow rings and ellipses, but following a surface may well be too much to ask, even with a theoretical unlimited energy supply. If anyone wishes to expand on this, especially in the theory of the standing wave and flux field requirements, I could use the input. Don’t bother trying to tear it apart, I want to make it POSSIBLE. BTW, if this works, especially without monstrous rings of fluid metal traveling in a ring at incredible speeds…. Think “old school,” where the things we know are not just simple, but doable with what we have! PUT ON THE INNOVATION HAT!

I'm glad you posted this video now because recently I've been thinking about how stupid and impractical (impossible?) the shielding is... Yes you should have shields (if that's even possible) but there should be a backup system of armor for all these ships... -Armor plating -Expanding blast resistant fireproof expanding foam -I mean you could even use water that would freeze in contact with space One of the problems I have with Star Trek (I know it's all for drama) but the ships blow up too easy. Also since all the room/cabins are on the outside of the ship, before the ship blows up it could eject each room as an escape pod with a cloaking device so most of the people could get away, of course the crew in the bridge,etc would go boom.

[@casbot71]

They do use blast _resistant_ fireproof expanding foam. It looks like rocks......

[@gmradio2436]

Most ships do have armor. At least in Starfleet and given video evidence so do the Klingons. Star Trek weapons are just insane. The basic torpedo is an antimatter explosive more destructive than a nuke. As for cloaking devices in escape pods, that is an international incident.

[@mdsx01]

Bit of headcanon here, but I think that polarized hull plating never really left. It got incorporated into the ships structural integrity system. Thats why unshielded hits dont just tear the ship apart in a single blow. The yield of a photon torpedo is in the megaton range, which should have blown the Enterprise Ds drive section to pieces with the first shot. Something had to be resisting all of that energy throughout the entire structure of the ship.

[@ilejovcevski79]

What make it even all the harder is the constant changing over what's spoken over time in different shows and movies. At one points they even mention screens and deflectors as separate things, not so different to what Star Wars does, with the former blocking energy and the latter solid matter. Of course, by the 1980's it was all rolled into one. Good vid BTW!

[@paspax]

Early on, Roddenberry had meetings with writers to explain the difference between deflectors and shields because they were conflating the two and using the term 'deflector shields' in their scripts. Deflectors are not shields.

Tasha Yar in Yesterday’s Enterprise refers to increased heat dissipation as an improvement in shield tech and being able to stay in a firefight twice as long as the C’s tech would allow. So maybe ‘deflection/energy dissipation’ is an issue too

[@stephenolender6219]

Its known as feedback in lore, the energy that impacts the shields has to go somewhere. So what would happen is that the energy goes to the emitter and results in waste heat. This heat needs to be dissipated to keep the emitter operating optimally.

Something I've always wondered is why they never thought to weaponize shield emmitters. Just imagine what they could do with a shield energy field that has been shaped into something akin a phaser lance attack.

It did also have the disadvantage that it burnt out the main deflector, which had to be repaired before the ship could do FTL again.

The field that keeps the beam together (longer range, less damage, as the field loses power and the beam just desintigrates). I would guess that the frequency is that field, as we can see in one episode were they were shooting with different charges against the Borg and the phaser changed its color. I would say the Borg adapt First to the field frequency and are able to disperse the energy, then they actual manage do adapt to the particle it's self, we're changing the frequency wouldn't bring any affect and they may then even be capable to use the free electrons to power the forcefield it self

Maybe a good shield officer could prepare the shielding for specific threats instead of just reacting. Or the Galaxy just had the fancy "automatic" shielding upgrade package.

I had always just assumed that projectile weapons in Star Trek weren't really used in ship combat because of their speed limitations. The distances involved in space combat combined with the travel time of projectiles would make actually hitting a target with them quite difficult, and distant ships could detect the incoming fire and just move out of the way, something that light-speed energy weapons compensated for. Not having to compensate for projectile travel time and relative velocities of two moving ships using randomized evasive patterns is a big plus. On top of that, the electromagnetic and gravitic distortions of a ship's shields would in theory make guided projectiles like missiles either not be able to lock on to an enemy, but also probably detonate against the shields if they DID hit, and do little if any damage to the target ship's hull. Better to not bother with that and just use energy weapons. Just blast your enemy's shields with visually-targeted energy until they drop or the generating mechanisms burn out, then finish off the helpless enemy.

[@glenyoung1809]

I think warp field technology is involved with shield/deflector technology and the development of both technologies run in parallel. The stronger your warp engines the stronger your shields are as well, in general and would explain the gradual increase in shield toughness over time. Gravitons are the quanta of a gravitational field in the same way that photons are the quanta of an EM field. I conjecture that a shield bubble in the Star Trek universe is boundary of a warp field bubble/volume which has been enhanced and reinforced by graviton emitters(similar to the tractor beam but vastly stronger). They may even have coherent graviton emitters (analogous to the same principles as a laser in EM tech) for vastly increased power. At this warp bubble boundary the gravitational gradient maybe enhanced to millions of G's which warps the spacetime in that boundary and can refract any incoming matter and energy. It also makes sense because in TNG they've mentioned more than once that the warp engines can be tied into the shield emitters to bolster the shield strength. The durability of the shield depends on both the durability of the emitter and the amount of power available to power it since the emitters drain much more energy than even the warp core can produce at full strength. I think the navigational deflector is simply the graviton shield emitters turned on at very low strength.

I have always felt that in its simplest form, deflector shields work by distorting space so the beam simply misses the ship. Of course it has to stop proximity explosions too, so an area of distortion preventing you from drawing a straight line from outside the shield to inside the shield will work too. The graviton is necessary for this technology, though, bevause the graviton is the only form of energy that can distort space. Which links it intimately with both Warp Drive and artificial gravity.

The Deflector is a low power long acting thing.

[@trekkie1701c]

I actually had a thought on this recently. If the shield is an energy field that can be disrupted then *any* particle - such as a photon - hitting it would result in some tiny change to the field. If you could detect these changes and feed them into a powerful enough computer, you could form a rough picture of what's on the other side of the shield, and we already have the tech today to generate imagery of all the things we see in Trek. If you get something that vaguely suggests the outline of a Bird of Prey with the generalized EM signature of a bird of prey you can guess it's a Bird of Prey and adjust whatever image is shown accordingly - and we know that sensor ghosts can show up on a ship's display as the actual ship, since Worf has used that trick once. As for seeing outside of the ship, it may be that the field is somewhat directionally selective in how it disrupts output and it's only for some things which are too high energy or which require some level of high-fidelity bi-directional communication that you might have some sort of issue. With that said, Starfleet shields do apparently have a 'refresh' cycle which largely would solve this issue, as it means there's non-continuous gaps in the shield and a sufficiently high refresh speed is basically invisible to the human eye (you probably don't notice that the display you're reading this on is rapidly refreshing the screen, for example)

[@KRAKEN.983]

Ok, Stay with me, I am thinking hypothetically here: So to fire through their own shields, they have to match the phaser and shield frequencies. They can fire through a targets shield if the know the frequency which means when they fire, both ships would have the same shield and weapon frequencies. Seems a bit risky considering you would effectively have no shields as the enemy fire would would be at the same frequency to penetrate your shields. Its fine if you're firing a "Shot" but phasers tend to be a continuous stream for a second or two so once they realise you fired through their shields, if they're quick enough they can so the same knowing the frequency snd with automation it could literally blow up in their faces (and hsve concrete falling from the ceiling for some reason 😂)

[@lcarsos]

Roddenberry hated it whenever a writer slipped the word "deflectors" near the word shields. He said that those 2 systems were completely separate, for different purposes, and different technologies.

[@HunterDrone]

the lack of transporting through shields could be an issue of bandwidth.

[@materialdialectics]

Actually it kinda makes sense that we see beaming through shields less. Because with the whole refresh rate frequency idea, when it comes to energy weapons it doesn't really matter if 1% of the energy doesn't make it through due to slight inaccuracies in one's knowledge in what that frequency is and/or the accuracy of whatever is controlling/generating/regulating the frequency reference (like how a radio needs to have the oscillating frequency generator for reference to process the incoming information normally via the use of a crystal oscillator; I might be screwing that up slightly or oversimplifying). However with a transporter.... that 1% may very well be the difference between life and death for the person beaming through.

[@Greg87601]

Shields up.

[@Star_Ark_Ayrania]

One possible explanation for the deflector shield is the "positive curvature bubble". As we all know, the conventional spacetime curvature is "negative curvature" from a simplified flat perspective. Therefore, the straight line vector from the flat spacetime perspective will be deflected to the inside of this negative curvature depression. Then, if we create a positive curvature spacetime bulge in reverse, we can form a repulsion and deflection effect. And it just so happens that this is exactly the structure of the warp bubble. An important difference between Star Trek's warp engine and the Alcubierre engine is that it first forms a sub-spacetime bubble to wrap the starship, and then warps the spacetime outside the "warp bubble" for propulsion. Considering Star Trek's in-depth development of gravitons, subspaces, and spacetime phases, this technical principle is feasible.

[@illusionuk]

In regard to a vessel matching their shield frequency so they could fire through their own shields, I always felt this was a plot hole in Star Trek: Generations. When the Klingon Bird of Prey matched their weapon's frequency to the Enterprise-D's shield frequency, they would have had to match their own shields to the same frequency to be able to fire through them. Therefore when the Enterprise-D returned fire, they would have fired straight through the Bird of Prey's shields as the frequency of the Enterprise-D's weapons would have matched the Bird of Prey's shield frequency, and they could have destroyed the Bird of Prey in swift order without needing to find a weakness in the cloaking device's plasma could they could exploit.

[@Marcus51090]

Some energy does manage to bleed through the shield tho.

[@firstcynic92]

4:25. How do shields work in ST lore? Deus ex machina.

[@matthewweekes6576]

The shields in the first movie used multiple emitters that each had a piece of a very strong and resilient plate of metal then energy is run through it making a copy appear outside the hull. As described in Mr. Scott's guide to the Enterprise.

[@petepanteraman]

I know this is for laughs and intrigue, however if something we're to be effective for shields then it would stand to reason that shields would be black or something similar to polarized sunglasses, there is no way the shields would be clear. Because energy weapons are similar to light and in order to block light you need a filter.

[@deusexaethera]

Maybe the shields just cause torpedoes to detonate prematurely by screwing with their impact sensors.

[@Monni95]

As with any technology based on magnetism, it can either attract or repel metallic objects... This means the object must be either magnetic itself or attract magnetic force, obviously meaning that the shield and the object have opposite polarities. For non-magnetic objects and matter, extra layer must be added to generate gravity field that for example repels or slows down any matter, like ozone in Earth's atmosphere.

[@durocelisar]

Seems like starfleet vessels use the hull plating polarization still, the shield that hugs the hull and the area shield was a new development that was premiered in ST: motion picture. Hence the line, "the new shields held."

[@EnderMalcolm]

I'd be curious to see a future shield design which uses modern day asteroid shielding as a basis. You have a bunch of angles built into the layered plating, which diverts the impacting material by "normalizing" its trajectory with the plate. This could be used in shielding to not just defeat an incoming energy beam, but actually turn it around to a point. Let's say that under light fire, the shields could bounce the beams back fairly accurately, but under heavy duress, they kind of just glance off, saving as much energy as possible for the next impact. The downside is that this would have an absolutely catastrophic effect on any solid matter impacting the shielding at relative speed. Like a giant cheese grater.

[@Blutwind]

My biggest gripe with shielding is how random its effect is. Like in one scene it is blocking all kinetic energy making it dangwrous to impact even with another ship and in the next a random astroid(even though bigger or a way smaller jem harda craft just passes through ramming the ship in the process. And then there is the thing that ships under fire have exploding consoles and celling rocks fly everywhere only for tactical to say "shields holding at 70%". Second heavily implies that impacted energy still somehow gets imparted into the ship by some kind of reverse energy flow or kinetic momentum

[@talltomtube]

Here is how they work. Much technobabble. But based in current day Science. Forcefields/shields work by projecting a dense Sigma Baryon field between the emitters. When interacted with the Sigma Baryons decay into Lambda Baryons, or something close to Neutrons. Due to the Inverse-square law the small amount of Neutron like emissions radiated by the Sigma Baryons decaying into Lambda Baryons is negligible. This keeps Neutron like radiation at a level safe set by Federation standards. However, when Sigma Baryons decay there is also a secondary effect called the Pi-Zero weak interaction. This effect emits electron positrons and thus the annihilation of nearby electrons are ensured. So any incoming weapons fire that has electrons is annihilated. This annihilation causes matter to be converted in to energy (E = mc^2). This is why there is a visible 'light effect' that happens as the field is interacted with. The 'harder' the field is under pressure the more visible light effect there is. Therefore, more matter being converted into energy can also cause heat radiation and burns. This is also why you can see a forcefield being 'put up'. As the forcefield is put up it has to move the air out of the way of Sigma Baryon field. That is why brig force fields also 'sparkle' when turned on. Because a small amount of matter is converted into energy as the forcefield engages, thus the light effect when activated in an atmosphere. When a forcefield/shield engages in space, which is basically a vacuum, you don't see this energy effect as much as space is basically empty. The power requirements that are used to make a Sigma Baryon field are immense. That's why forcefields/shields can weaken overtime, as they are being energized/matterized(?) by gigantic capacitors that must be recharged by the Warp Core. That's why star ship shields can take several minutes to be brought back online.

[@feralprocessor9853]

Very bright and colorful presentation

[@Jayjay-qe6um]

Shield strengths seemed to vary, making an exact calculation of how much damage they could take impossible. However, there were some examples: •A Constitution-class starship's shields could take the equivalent of ninety photon torpedoes t once. They could do so a total of five times before shattering completely. •A Sydney-class starship could be destroyed by two photon torpedoes from a Galaxy-class starship with weaken shields. •According to Malcolm Reed, the shields of the 22nd century Nausicaan ships won't hold against a torpedo from the Enterprise NX-01.

[@22steve5150]

I wish they would just do a complete reboot of star trek and all of it's technology. For instance, deflector shields working only against energy weapons, requiring point defense guns to shoot down incoming torpedoes, coilguns or some other weapons that fire physical rounds and of course physical defenses like reactive armor, NERA armor, and electric reactive armor to mitigate against such weapons, and of course, replacing idiotic "cloaking" with systems that make detection more difficult at longer range and when "running silent" and make exact weapon targeting more difficult even at closer range instead of the "magical" nature of post ST-VI "perfect" cloaks.

[@TheReaverOfDarkness]

I have often speculated which Master of Orion 2 technologies a given starship or station in science fiction would have. For Starfleet shield systems, I have thought Class V or Class VII shields with the Hard Shields augmentation. This doesn't quite fit, however. While Hard Shields protect against some things which Star Trek Deflector Shields protect against, they also protect against more which Deflector Shields do not.

[@michaelmutranowski123]

if I'm remembering correctly, the only species we see beam through Federation shields are: the Borg, the Dominion, and the Voth. I think I'm forgetting one, but it's late and I'm tired so I can't think of 'em at this moment. Also, I keep thinking about Stargate SG-1 and Stargate Atlantis.

[@congnghequansuvn474]

if i have to guess it some form of particle shielding, that use magnetic to regulate, and it is not soft but extremely durable

[@nymalous3428]

I always thought that one of the shield "layers" was from very short ranged repulsor beams. They have the technology to tractor/repulse objects, so why not physical weapons too?

[@vedranknight]

The reason why torpedoes hit the shields is due to the speeds involved. Torpedoes are fired at relativistic velocities and use warp sustainers if fired at warp speed. Any object like that striking a charged plasma field, like a ship's plasma shield, would go through a rapid change in speed. This shock would prematurely detonate the warhead at the shield's perimeter unless the warp sustainer could be configured to match the shield's frequency, effectively passing through it with no shock.

[@Numba003]

Thank you for another dive into some Trek tech! I enjoy seeing a synthesized presentation of all the various techno-babble into one coherent picture of how the tech works. God be with you out there everybody. ✝️ :)

[@Reoh0z]

Speculation: If you try to shoot through shields and it doesn't work, you just hit the shields. Perhaps if you beam through shields and it doesn't work there might be more serious repercussions. Like death of the away team, or accidentally setting off an explosive on your end rather than theirs.

[@disky01]

If no matter or energy can pass through the shield, how does the ship move while shields are up without exploding? I feel like there would be a lot of energy building up inside the shield while it was moving.

[@SKaVeN9798]

Any chance of an episode about the NX-01 refit (seeing as Enterprise got cancelled before we got the chance to see it)?

[@Skull-in-the-house]

Nice breakdown thanks for the video

[@Gruegirl]

Most likely, shields work the way Nerdist says they do, *BUT* Star Trek also loves playing around with gravity/gravitons. So if there were layers of gravity inside the artificial ionopshere pushing in and out simultaniously, it could deflect physical objects or crush torpedos causing them to detonate far from the actual hull

[@AlternicityBlogspot]

Is phaser dimpling a thing in canon anywhere? I don't even remember where I read about it, maybe FASA trek.

[@z00ropa]

The is a STNG episode where Riker says that lasers wouldn't get through their shields. If lasers can't get through than light couldn't, and couldn't get out.. so shields up, lights out.

[@Parmis_Dax]

Another great video, thank you

[@sheilaolfieway1885]

6;27 where is that scene from?

[@ShiftySqvirrel]

I always figured that forcefields weren't just energy but a form of manipulated matter as well, and that's how they can stop both energy and physical objects while still being more "realistic".

[@thomriley1036]

"Shields" are an odd concept the more you think about them. We're so used to them that they're just accepted in any old Sci-Fi thing. But, consider the vast differences between Star Trek, Star Wars and Dune's various shield techno-babble.

[@Maves916]

honest question, how do you even get into STO to get the shots. Anytime I open that game it crashes on loads lol.

[@josephellis4644]

I am almost certain that I read that the shields were literally a shield of projected transparent aluminum surrounding the ship, creating an eggshell of protection.

[@smoldragon339]

One thing I've always wondered is how attacking deflector shields will drain them.

[@wickedcircle]

3:48 what game is it?

[@keiyakins]

The real question is why no one uses visible light lasers. Sure, they're less efficient, but shields let visible light through unimpeded as evidenced by the fact we can see the ships.

[@BaalFridge]

adding layers of technobabble fixes everything. I don't mean that in a mean way, I genuinely think it's great we can come up with pseudo-physics explanations for everything.

[@alexandarvoncarsteinzarovi3723]

Armor vs Weapons is external battle, yet both give way to the passage of time,

[@MRB1157]

Can anyone explain why rerouting power to a downed system, such as Shields, magically makes that system work again?

[@Mastervitro]

So to make a force shield you just need to bend space, got it! But what about holograms?

[@besaidknight]

Shields in my own head: Some kind of specialized high speed short range high power repulsor tech (Doesn't explain hull hugging shields from tos )

[@bipolarminddroppings]

All that keeps you from falling through the floor is the electromagnetic repulsion of atoms on the tiniest distance scales. Therefore, in principle, you can create a solid barrier with nothing but electromagnetism, that is how shields work in Star Trek.

[@brodriguez11000]

The weak force is weak and short.

[@gamerboiiiiiii]

Pew pew bubl bubl bloc bloc

[@withershin]

Smart move opening a certifiably ingame episode on shields with a Defiant-Class. We got armour too. Nerds. Edit: sorry you covered the shields transporter thing. The transporter is a death machine so it doesn't really matter. Nerds going to Nerd out.

[@jakexou812]

Another great video! But I must add, that any minutia details about the operation of shields or ingredients thereof that nobody seems to be able to fully answer or explain, I would just chalk it up to being an extremely guarded technical secret by Star Fleet. In other words, it's "CLASSIFIED" military information. ;)
