The Actress Amanda Tapping would probably love to hear from you. As the scientist character she read popular science books and demanded lines explaining something wasn't working according to the known laws of physics so she wouldn't look stupid. The production gives her lots of credit for keeping the science in the science fiction, as much as it ever is in these shows.

Allegedly David Hewlett, who played Rodney McKay, also liked to know the real science behind his lines. Fun fact both Tapping and Hewlett were both born in Southern England before their parents emigrated to Canada.

Yes, both Tapping and Hewlet are a big driving force why the science babble is just so plausible, if not down right accurate. I mean it's still speculative science fiction, and i expect it to go weird and wonky places and it does, but the basis in which it roots is just so god damn solid and firm that even the most ridicolous 'problems of the week' are just a joy from a casual perspective as well as a sciency. very 'grippy' (as in, comfortable to grip, lays in the hand well, like a tool e.g.) as my prof used to put it :D

The explosion moving the wormhole isn't really supposed to work with the known science of wormholes, but is actually specific to the Stargate technology that is creating them. A previous episode established that a large energy discharge directed toward the gate would cause the wormhole to jump to another gate within the Stargate system.

[@poulay4267]

was wondering if someone would point that, and if not i would, but you did it ^^

[@humorpalanta]

Yes. You are right. And to establish it further: The Stargate itself is a very complicated supercomputer or just call it a "door". The door itself works by bending space and time itself but on a controlled level. (as we would imagine a wormhole working between 2 points of time and space). So the Stargate iself is a computer and it has in-built commands for special scenarios like this. Just to stop it from exploding itself by overcharging itself. (This can be broken though as we have seen in Atlantis.) Basically the Stargate is a system of a computer and the "door" part. This door works by bending space and time as we have stated. But it bends it in a controlled environment. Within the gate's circular space and the part where this time meets our time is called the event horizon. Or you could think it as how water and air is divided. The Stargate is built from a very heavy matter called Naquadah. It is an extremely good superconductor. Basically you filled it with energy and it will grow its mass and bend time and space. But if the energy isn't used up for creating the wormhole itself it will overcharge and blow up. So there is a safety function to stop that. It means the Stargate will do its best to find a way to the energy to be discharged. If you overcharge the gate it will redirect the energy to somewhere. And since these Stargates are connected the gate will wind its closest "friend" which will help it discharge the energy thereby stopping it from exploding. That is why the bomb works. Because it works within the rules of the Stargate's function and has little to do with the wormhole itself. She should check out the complete series and talk about it later on as there is actually so much told us about how science works within this parallel universe we call Stargate "world". If you think within the rules of the show you can find that they actually miss really really small things and just very few times contradict themselves. Also yaaaay for Red Dwarf. I love that show.

[@BigHalfSteps]

Known science of wormholes... that is based on theories based on hypothetical assumptions. Sorry, but no. There is no KNOWN science to wormholes. Also the Stargate is complex, and whatever it does is only understood to be a wormhole as we know it. It could be a completely different thing, but it is/was titled as wormhole because it theoretically looked, smelled and acted like one - so it should be a wormhole. Even though wormholes are so hypothetical that there might be different versions of wormholes, similar to black holes having different versions (small ones, solar system sized ones, merging black holes (though again just hypothetical and not discovered yet) and ultra mega sized ones). And yes, I'm talking about sizes, yet we have to even remotely find out how the black hole inner workings work on reality in order to differentiate every single black hole from another - we just don't have enough data to find any if at all differences.

About the Molecular Deconstruction, it was determined earlier in the series that even though it seems that you go through in one piece your body is actually turned into energy and then rematerialized by the receiving gate. Watch The Torment of Tantalus (Season 1, Episode 10) where they discover this information. Also to further explain how it works is in the Stargate Atlantis episode Thirty Eight Minutes (Season 1, Episode 4) where a puddle jumper gets stuck in the gate.

The molecular deconstruction actually has an in-universe explanation: The wormholes created by stargates are Einstein-Rosen bridges with a bottleneck only large enough for a single atom. Because of that, they need to break things down to and turn them into a stream of single atoms to fit them through, and that process, as well as reconstruction on the other end, are handled by the stargates.

[@IceMetalPunk]

It also allows the stream to be sent at near light speed, if I remember right. Since a wormhole just shortens the distance between two points, it doesn't necessarily make it instant, so being able to transmit the matter at relativistic speeds also makes the whole process faster.

Which in my head-canon explains why objects can only travel one-way through the stargates.

Neutron stars get smaller as they gain mass increasing in density, so if enough matter is nearby, they'll eventually become black holes.

The sci-fi explanation of the stargate is that it is creating a “artificial event horizon” and deconstructs matter and transfers it through a small wormhole as energy.

[@Tech2188]

Thank you, yes

[@Erkle64]

It actually sends things as atoms rather than energy. That's what allows them to dump a heavy element into a sun in one of the episodes. Which, in my opinion, makes it different from teleportation because your actual atoms are used to recreate you rather than the energy from your atoms.

[@dungeonsdoodads4306]

The show explains that the artificial event horizon doesn't send things that pass through it until it detects the item has completely passed through one side. So it decompiles the item at the origin, sends the raw materials as a coded to packet, and rebuilds it at the destination complete with orientation and momentum.

I don't know if her hospital had a tunnel access point or if it was about transport to a tunnel access point, but she was given confirmed existence. Additionally, NORAD was built to be the fallout shelter for government officials as it is deep enough to withstand a nuclear bomb dropped on it and is specially engineered to withstand earthquakes as well.

Re: the redshifted image, I think they were saying the camera was further up the gravity well than the people so the light it was capturing was red shifted. Honestly not sure if the distances involved would make that any more plausible but it’s at least different than the transmission being red shifted.

[@SpectrumTwist]

this is precisely my thought, trying to find anything in terms of what a camera at relatively close range to a black hole would do to the light it captures would suggest that it would red shift just like how the telescopes would. So the amount that time has dilated on the planet and how much it's shifted. Stargate explained the signal red shift already, i honestly didn't think they were talking about the signal being red shifted would cause the image to be changed, just the fact that there is already so much gravity and time being warped and stretched, that the light reflecting off the objects and people that camera is pointing at is being slowed down considerably enough to give the camera a heavily redish image, i'm sure the sensors on a camera would accurately show that.

[@geoffstrickler]

For the light on the planet to be redshifted enough to cause what was shown, the gravity would be far too great for anything other than EM to survive, we wouldn’t have pictures of people to transmit, and the MALP itself would probably not exist. The slow frame rate was far more realistic.

[@markelliott9737]

I suspect it was a graphical decision by the designers - basically, if it is red shifted it must be red right?

[@dannyravelo1401]

The red shift is relative. If you're standing still, as the camera is, you don't perceive the red shift. It's only when you transmit the signal to an observer at a different time-relative distance that you perceive the red shift. So yes, only the signal gets shifted, but not the image itself even if the camera was just outside the event horizon (and survive the spaghettification)

[@geoffstrickler]

So with the molecular deconstruction it's a function of the stargate. It breaks you down, sends the atoms through the worm hole, then reconstructs you on the other side. The theory is that it protects you from the exotic matter holding the worm hole open. Also from what I understand in the opening scene is a rouge white dwarf entered the system and drew matter from the larger star and became massive enough to implode and collapse into a black whole.

Not everyone will follow the physics mumbo jumbo that's being thrown around. Sometimes they're talking about a solution, and sometimes they're talking about a problem. It can help if they make it clear to the viewer sometimes, which is part of the challenge of writing stuff like this. They can't let it be obvious that those lines are intended for us.

Later when SGC became more international she was still the best because by then she had more experience with alien tech than anyone on Earth.

It wasn't Voyager/Gilligan's Island where you know you're just never getting home. Too many teases. Stargate takes place in present day, operating out of a secret underground Air Force base, with a notable learning curve at the beginning of the series. As the show progressed, they found key technologies and important artifacts to help them protect the Earth from alien threats. Nor did they take stupid chances. When first visiting a new planet, they would send a MALP to get some video intel of what's all there. Only then would they send real human people through the gate. It was still plenty dangerous, which is unavoidable, but they didn't constantly stumble into moronic problems. Not a lot of dummies on the show. Not even Jack.

This is not at all clear from the mathematics that give rise to an Einstein-Rosen bridge. We don’t actually know enough about what a theorized worm hole would be like to determine whether or not gravitational effects could pass through. We don’t know enough about gravity itself either. But it is an interesting premise to play with in sci-fi. I think it’s unlikely that gravity would pass through, but I can’t say it wouldn’t.

[@jardix3667]

I totally agree with your point, and was moderately annoyed someone had already made it. My addition being that the Stargate has been shown to have a 'safety' function that actually generates a fair amount of 'suction' to ensure a body moving through the event horizon continues to move through. That way, no one gets stuck. If, say, their right leg is dematerialized and they stop moving halfway through the 'step' that takes them in. The Gate would continue to pull them in, regardless of whether or not they're still technically moving. Even a small amount of 'suction' by the Gate itself would exacerbate that effect of space being expanded or duplicated through the wormhole.

[@elzar760]

I kinda thought the same thing. If this bends space, so that you can walk through from one point to another without violating the speed of light, then that space is effectively right next to you. If gravity is impacting space that’s right next to you, I would think the gravity would effectively be right next to you and thus be able to affect you as well with the next moment when that gravity moves at the speed of light to you. But again, wormholes not being understood and theoretical, I can’t say. All I can say is I don’t know that we have enough information to poo poo the concept out of hand without more information. Not trying to bash on anyone for thinking it could or wouldn’t happen, just saying I’m not sure I’m on board with dismissing the possibility out of hand :)

I don’t think the frequency was shifted, but the time dilation delayed the signal so much that the code didn’t register at first. As for the explosion they finally went with, that does not destroy the wormhole, a previous episode established that a blast directed at the outgoing gate, will cause the receiving end of the wormhole to jump to a different gate.

[@aarond0623]

Well technically frequency is a measure of occurrence per unit of time. So if the transmission is getting delayed, i.e. is arriving slower, than the wave by definition would have to have a lower frequency. E.g. if normally the wave is 1 MHz and it's arriving 10 times slower, it's going to appear like it's a 100 kHz signal.

So you can stick an arm in and pull it back out, but once an object enters completely, the gate will try to send the packet through.

You said it, that wormholes are completely theoretical at this time. One of the big points of the show is how the actual wormhole the Stargates create defies most known physics. It's pretty hilarious, because the show often has some pompous physicist that get clearance to work in the Stargate program, acts like "the science is settled" because some smart guy made a theory with no proof to back it up, and then they have to go through the process of humility when there's the wormhole right in front of them, behaving in ways it shouldn't be, but it is, because our understanding of physics is like a toddler's understanding of nuclear fusion. This is made very clear in an episode where a race of more advanced humans can use devices that let them pass through walls, yet not fall through the floor. The one guy can't even explain it to Sam, despite her intelligence, because despite being a genius, she's a moron by their standards. He basically just tells her that any technology sufficiently advanced is indistinguishable from magic to a less developed being. It's a brilliant way for the show writers to have creative liberty, and not worry too much about the theoretical physics at play, and instead, just enjoy the story. As for the red shift, depending on the gradient of gravitational force, perhaps the light was red-shifting prior to contacting the camera sensor on the probe. oh, and the probe DOES get deconstructed - as do people, because matter isn't sent through the gate: The matter gets converted into data by the gate, including its velocity upon entering, then stored in the gate's data buffer, sent to the other gate, then reconstructed. Again, the technology is sufficiently advanced that while not explicitly stated on the show, it is implied the scanned data goes all the way to sub-atomic, even quantum resolution, so every atom, electron, everything about you is copied and stored in the buffer at the time of entry, even possibly such resolution as to be able to scan the soul itself (as we see one of the ascended ancients in spirit form pass through the gate). This copy method is delved into quite a bit in the episode where Teal'c is trapped in the buffer during a combat induced malfunction, and they realize as a safety mechanism, the gates clear the buffer whenever an incoming or outgoing wormhole dials in/out. I think you'd really enjoy the show. It's one of the smartest sci-fi shows I've ever seen, has VERY memorable characters, and fantastic stories. There's definitely some non-sense, but for the most part, it's easy to suspend disbelief with this show, and just enjoy the ride.

[@wolvenar]

The part I find the most incorrect, nobody seems to be addressing. For the gravity increase to happen, there would have had to been an incredible increase of mass. Just a star collapsing into a black hole didn't increase mass, just the concentration of the existing mass. A nova/super nova as far as I understand it is the stars outward pressure losing the battle with the gravity. It's not shielding the universe from the existing gravity, the gravity was always there. For this episode to make sense the second star would have had to entered the solar system via mutual attraction quickly. Then by feeding on the solar systems star tripped the balance of gravity and outward pressure of the more massive star. The gravitational and relativistic effects would have been increasing as the star entered the planets system. They would obviously increase as the alien star got closer. But the super nova would not have suddenly changed the gravitational forces. Or am I missing something in my understanding of gravity and super nova?

[@michaelkenner3289]

Gravitational force is determined by two things, mass and distance. Mass increases gravity linearly whereas distance has an inverse square relationship. That means if you want to really change gravity, the distance part will be much more effective. The black hole (more accurately its accretion disk) is visible in the sky from the surface of the planet, that means it's extremely close. Like the moon close. Which is scary even just with a single stellar mass to work with. You see the black hole start moving towards the other star at the beginning of the episode. This is a bit weird because the mass is the same so the balance of forces should be roughly the same. They seem to be implying that the increasing gravity comes from the black hole moving rapidly towards the planet. This makes perfect sense in terms of gravity but I'm not sure what is explaining the overall motion happening here.

@@michaelkenner3289 Huh, that gives me some thoughts on how the planet could be getting closer to the blackhole, although I'm still not sure that the scenario would work. B (the blackhole) S (the other star) P (the planet). B is accreting matter from S, that means S's mass goes down. That means if P is orbiting primarily around S (yes, there are issues here given the visual we see), then P's orbital radius would increase and *might* cross into the sphere of influence of B instead? If so, that new orbit of P isn't necessarily going to be well aligned to *not* be highly elliptical around B. Start the episode with P at its apoapsis and by the end it's very close to its periapsis. Add in some handwaving for "the episode is 42ish minutes and they didn't want to show this taking days, weeks, months" and maybe it works.

The Red Dwarf episode "white hole" could be a good one to watch, it's series 4 episode 4. Plenty of physics in that one. Love your videos by the way!

[@katalytically]

In this episode of SG-1 the smaller star was actually a neutron star which was accretiing mass from the larger star and gains enough mass to collapse into a black hole. One of the assumption for "Gate Travel" is you step through one gate and immediately emerge on the other side. This is in contract to the original movie but eliminates the time consuming depiction of actually traveling through the wormhole. Because of this the episode assumes that some aspects of being close to a black hole are not dissipated by the wormhole, some are reduced but not eliminated, and some don't apply at all. Hey, it's TV, so sort of accurate and sorta not based on whether it serves the plot line. Part of the plot line is that they cannot close the gate which means they are continuously connected to the planet through the wormhole and that even though the wormhole is insulating them somewhat, the the effects of the black hole are slowly increasing so the "earthquake" is not from a gravitational wave but the gravity from the black hole continuing to increase through the wormhole (the same being true of the time dilation. So some pretty good scientific explanations, some harder to believe or outright wrong explanations that make the plot work. From an audience standpoint they have heard of red shift so they will expect to see things shifted to the red and therefore looking red. Not accurate but much easier to explain than "the radio frequency was red shifted so we need to compress the signal so we can accurately see the picture." As far as spagettification is concerned, I think the people would get ripped apart from gravitational tidal forces before they ever reach the event horizon, or even get incinerated as they become part of the accretion disk and heated to millions of degrees as they orbit the black hole. But sucked-in sounds so much better. I like your description of a black hole being like a Hoover vacuum cleaner though. Remember that in SG-1 the gates are at each end of a wormhole so if you destroy the gate at the other end of the worm hole you would effectively close the wormhole. Any way, I like how you explain what is mostly accurate, what isn't, and why it isn't. Thanks for the reference to Red Dwarf, I was only able to see one or two episodes so I think I will binge watch the series to see what it is like.
