Hey Kyle, love the show! If you want to give a very accurate visual representation to these scenarios, check out Universe Sandbox. You can easily generate events like a micro black hole orbiting Jupiter, and observe the temperate increase. It may add a new element (hah) to your videos that the visual learners will appreciate.

[@dragon12234]

To be fair regarding the vampires. From what I've heard, it's because old mirrors had silver, and there was some "reflection of the soul" deal going on. So, as Vampires don't have souls or something, they don't show up in silver mirrors

[@vlert]

I fully expected him to say "because they suck." when he asked "Do you know why I hate vampires.".

[@becausescience]

DAMN -- kH

[@ArynosValinir]

Though, the whole idea/misconception/superstition that vampires would not give a reflection in mirrors stemmed from the idea that silver had damaging and/or anomalous properties against the supernatural. This 'pure element' for a great length of history was the backing of most mirrors that allowed for reflections, and people believed since they had no 'soul' and that mirrors reflected the soul more prominently than your image, you would see nothing. Although, to be more science-like with it I would say their concept was a simplified explanation of their ability to filter your perception. In essence, that perception altering, photon affecting, a vampire affected you with to make it seem like a normal being would not affect the mirror. The distortion of their image to create special cues meant to be translated by your brain to alter your view of it would likely be absorbed by some property of the silver rather than reflected. And your brain, not being able to translate the missing cues your eyes detected from the reflecting stimulus, would cause you to see nothing.

[@Lux_DeWarlock]

vlert honestly that would’ve been too easy.

[@jaojintalonis92]

@@ArynosValinir Interesting thought. Perhaps they are more like specters than physical beings, thus light actually passes through them to the reflection. They don't need to alter light, they only need to trick your brain. PS. I also thought that was going to be the punchline Vlert.

[@kitkollector2633]

@@ArynosValinir Yes, but if you watch the old Hammer Horrors, they showed that if you tried taking a picture of them, they also wouldn't be visible. I think more modern films have extrapolated that to not being seen on video monitors. In the end, it's a "magic/supernatural" causes this thing to happen, because scientifically it couldn't happen. Related, in some lore they don't cast shadows. Intrestingly, from wikipedia, "In 2006, a physics professor at the University of Central Florida wrote a paper arguing that it is mathematically impossible for vampires to exist, based on geometric progression. According to the paper, if the first vampire had appeared on 1 January 1600, and it fed once a month (which is less often than what is depicted in films and folklore), and every victim turned into a vampire, then within two and a half years the entire human population of the time would have become vampires."

[@NereidAlbel]

Vampires traditionally lack a reflection because mirrors used to be backed with silver, which is a "pure" metal vs the undead and otherwise cursed. They should have reflections in modern mirrors, however :)

Actualy people used to think that your reflectio was a piece of your soul. No soul=no reflection. This is why breaking a mirror is 7 years bad luck.

[@richard-gn3es]

Silvering is the chemical process of coating glass with a reflective substance. When glass mirrors first gained widespread usage in Europe during the 16th century, most were silvered with an amalgam of tin and mercury I think the idea of vampires predates silver in mirrors. Perhaps the bo reflection part was added later

[@bubaxis1]

"Vampires invisible in mirrors" is a concept that originates from old mirrors which were made from polished silver, and as we all know, silver destroys vampires. So silver mirror destroys vampires reflection but any other mirror or reflective surface (vampires skin included) is behaving completely normally.

[@Kusanagi2k]

Oh I like this reply xD

[@galenrichter41]

too bad that mostly got lost in translation with modern tellings and such

[@JohnSmith-qq7fm]

I'm guessing it's the antibiotic properties of silver that affect vampires (and werewolves). So, if that were the case, any antibiotic should be effective against the undead

[@MechabitGames]

Also if the vampire photons were destroyed in the mirror then you'd see a black vampire shape in the reflection, not the photons from behind the vampire.

[@bubaxis1]

I know, even if silver did destroy/filter out the "vampire photons" there would be just a black sihlouette on the mirror. But when we are talking about "magical vampires", I think we can bend the physics a little bit.

OK, I see a lot of comments about the reason why a vampire doesn't have a reflection, is because mirriors used to be made with silver, and silver is a "pure" metal, and thus won't show the reflection of an "inpure creature" like a vampire. I believe that is false. Mirrors may have had silver in them back then, but I can't find any credible source stating that that was the reason why vampires didn't have a reflection. Everywhere I have looked, it just mentiones the belief that mirrors reflect a part of your soul, and vampires don't have souls, and thus no reflection. Nothing about any silver. If anyone has a credible source, PLEASE show me.

[@Merennulli]

There are three ways of accounting for a lack of reflection from vampires. - First is that they aren't really there and you only think you see them - this could be accomplished by manipulating your mind in some way, or directing the light towards you in the form of a hologram. The latter wouldn't cast a reflection from your perspective because the light is coming towards you, not towards the mirror. - Second is that the mirror isn't completely reflective within the visible range. With a silver mirror, for example, you could have something looking like a pale-violet ghost that wouldn't reflect off the mirror. - Third is that they reflect just fine, but are doing something to actively prevent you from seeing the reflection. This would be a reverse of the first, with the vampire manipulating your mind to not see the reflection, or emitting light towards a mirror in a method somewhat akin to active optical camouflage. By the way, if next episode does not mention Illudium Q-36 Explosive Space Modulators, I will be very disappointed in you.

Vampires can be seen in modern mirrors. The only reason they couldn’t be seen in Bram Stoker’s time is because mirrors were made of silver. According to the mythology, silver is a form of Kryptonite for evil supernatural beings because it was the metal that betrayed Jesus Christ.

Hey Kyle, long time watcher first time commenter. The reason vamps traditionally can't be seen in mirrors is because mirrors used to be made with silver. A vampires weakness being silver, they can't be seen in a mirror. I'm sure you already knew this though. Keep up the good work

[@kirstyshadowdancer5095]

Okay @Kyle there are two popular explanations for why vampires aren't in mirrors. The first is exactly what your saying, they are more spirit than body (mostly invisible) and the image you see of them is being deposited into your brain telepathically. This is why they can change appearance and shape - they simply change how they appear in your mind as they have no body to speak of. The second is a riff off that where - they are not invisible but seeing them in the mirror is completely unfiltered and what you see is soo horrific that your brain actively tries to blot it out so rather than being invisible in mirrors your brain just says "Nope nope. Nothing there - it's way better than what I actually saw" and your just left with a horrific feeling of dread.

[@theedgycorviknight]

Vampires dont have a reflection due to the old thought of since mirrors were silver backed. Silver was looked at as being pure and vampires not being of human nature (impure) they dont have reflection in the mirror. However today's mirrors are not silver backed so vamps would have a reflection by that thought process.

Kyle, If two particles where entangled and one was passing near or through the black hole would the same rules of quantum entanglement apply or would the gravitational attraction of the black hole ruin the particles spin and would this affect the other particle? Would the two particles be able to relay information because they can interact with each other faster than the speed of light ('spooky action at a distance') and therefore allow the particles information can escape the event horizon of the black hole? !!Please Respond!!

[@jansonmur4362]

Vampires only have no reflection on silver backed mirrors. This is because of the lore on silver dealing with the refining process and it purity. Silver in monster lore has always been a repellent of evil and impureness. They would show up just fine on our aluminum backed mirrors nowadays.

About orbiting a blackhole I think what people doesnt understand is that the blackhole is the same mass of that the star it was made of (actually its mass would be lower than the star because of supernova taking out mass but whatever) the thing that changes is only how close you can get to the center of mass meaning center of gravity so it wouldnt effect celestial bodies orbiting far from it (aside from the supernova) but it would effect the things coming really close to it

[@PuristPlays]

This whole talk (teehee) got me thinking: 1 - If the sun did turn into a black hole, would it emit visible light and heat from the solar wind of the transformed sun? And if so, would it put out the equivalence of the suns heat/light? 2 - When the Enterprise tried to Warp away from the black hole in the 2009 movie (That was TEN YEARS AGO??

[@crazyphrog6289]

50 Seconds in and I already have a comment. :D I agree with your comment about Vampires and reflections. I also agree with NereidAlbel in that the older mirrors used silver and therefore only reflect pure instead of Evil Undead. Anyways, the Dr Who version of Vampies not having reflections is simply because the creatures are using a masking device to look human, but their devices can't mask reflections, and their forms are so complex that the human brain is unable to comprehend them so it ignores them. Similar to how we can always see the bridge of our nose, but our brain filters it out so that we don't usually notice it. :D. Now to watch the rest. I'm sure it's awesome. They always are.

[@Cruentus]

Of course vampires reflect light like everything else, which is solid. The believe of vampires having no reflection is a religious one and comes from the christian assumption, that silver is a holy metal. So the church statet that the holy metal would deny reflecting an unholy being like a vampire. Others say that the Mirror reflects your soul and since vampires have no soul, there would be no reflection. Because religion! Yeah, i think it's silly, either. And Kyle: Even if you don't like vampires, i like you. At the last GMSV (global meeting of supervillains) we did talk a little and i thought "What a nice guy! Completely bonkers for always calling assassins and trying to terraform the solar system for himself and his alien bretheren, but really nice!" :) P.S.

She goes and looks closer, sort of seeing ...is that a speck? She jumps back when it seems to pull at her nose. She reaches and it tugs at her finger. She tried a pencil and it grabbed it and slowly ate it. She ends up using it for a trash can til it starts pulling all the furniture....

[@marcoswappner8331]

Vampire explanation alternative: in the universe where vamipires exist, humans can only detect circularly polarized light with either right or left polarization. Vampires polarize light reflected off of them (as some materials do), and when the light bonces off of a mirror, the polarization inverts, rendering them invisible to us. If they were to be reflected more than once, we could be able to see them, but I'ts not usually that we see the reflection of a reflection of something, so that's where the misconception of them having no reflection came from. Also, being able to see only right or left polarized light wouldn't affect too much of the interaction with the rest of the world to for us, except it would be about half as bright.

Another problem with vampires is that they don’t have reflections is because the don’t have souls but corpses and inanimate objects appear in mirrors and don’t have souls

[@danielrhouck]

Traditional mirrors are typically silver, perhaps with glass in front of it. I think other things are often used now, but let's go with that. Suppose that vampires emitted visible light, but *only* in the absorption spectrum of silver or glass. Then wouldn't they show up to your eyes but not in a mirror? (I don't know how true this is, but I've heard that the origin of that bit of mythology is that silver is a noble metal and wouldn't show anything evil)

1 Love the show! 2 Vampires are heavily symbolic and image is strong with them. They cower at the sight of a crucifix, they can hypnotize people with a look, and they can make people see things that aren't there (or not see things that are). Since mirrors were made with silver, and they have an allergy to silver, their "magical" image could possibly be destroyed upon touching the silver or maybe that silver just cannot reflect their image. 3 How much fire can be on earth at one time while still leaving enough oxygen to breathe? If the sun turns into a black hole, could we heat ourselves with fire for any significant amount of time without suffocating?

Also, if the oceans freeze, ice then insulates them from the surface. Volcanic vents should support life for quite a while, giving another possible location for building habitats. Future video idea?

Hey, Kyle, what's your take on space combat conditions where ships operate under a vacuum? I once read a science-fiction series where everyone on the large ships of a space fleet wore combat suits and would affix helmets when going into combat. The air would then be pumped from the general hull of the ship and kept in large storage tanks (presumably with scrubber apparatuses and whatever it would need to keep producing oxygen) near the center of the ship where if they were blown up it was pretty much game over anyway. The military personnel would then hook into oxygen lines if they were at station or use tanks for running around, but the general philosophy of the combat doctrine of doing this was that explosions couldn't create pressure wave and in cases of catastrophic depressurization of compartments people would not be so easily sucked out (not like in the movies, the author does point out they'd have to be pretty close, but that without air it was even more survivable because they're already buttoned up). So what's your take?

Alright, Kyle...a correction for the video on corrections. IF a vampire(or vampyr, depending on your spelling) had no reflection in a mirror, it would still be easy to tell you were looking at a vamp. If they have a visible physical form, then the light reflecting off of the objects behind them would have no way to get to the mirror, bounce off, and make it to your eyes. So a blood sucking vampire(not bat) would appear in a mirror as a shadowy void moving through space, like wearing a zentai suit of Vantablack. If they didn't have a shadow, and therefore their body was permeable to visible light, then that would give the unholy undead no reflection, true....but then it would also be far easier to figure out who is who with...you know...a flashlight.

You're kind of not right about vampires. You're assuming that their visibility is a result of a passive reflection. But it's obvious that this is not the case, they must give off some light to compensate for a normal visibility, either to become visible to your eyes or to become invisible in a mirror. And by the Kirchhoff's law of radiation we know for sure that this process cannot occur in thermodynamical equilibrium, i.e vampire must spend some enegry to do that. Assuming vampire cannot control this ability, this in turn solves two other mysteries about vampires: 1) their love to spend time inside a coffin - to preserve some energy. 2) their "spontaneous" combustion under the sunlight - when they're trying to compensate for a highly energetic UV light, their mechanism overheats and breaks, releasing copious amounts of stored energy.

Hey Kyle love the show!! Btw can you make a video on what would happen if, instead of one sun, we had 2 sun where each sun is half massive as our current sun.

[@gandhinocelestin8885]

Kyle is definitely a mad scientist ! 😂

[@alec1575]

Something I noticed from your thumbnail; you could see stuff through the black hole but, wouldn’t you not be able to see anything but a black void of light in the center of the black hole ( well you really don’t see it but you see the absence of it) ?

The one thing supervillian Kyle can't beat...bureaucracy

[@blakebroacher9509]

Dear Kyle Hill, Vampires are supernatural and have magic abilities on humans such as hypnosis and compulsion. Who's to say that the vampire upon being seen isn't just emitting to the mind of who sees it what they look like, *hinting to how Vampires hide their true form* This would both mean that no reflections would be given as they are functionally invisible to light, and other non organic creatures. This also is useful as they can possibly choose to turn it on or off. Being seen is A. an adrenaline rush, B. Makes the human pump their own blood faster making it easier to drink through a major vein. C. They're known in some areas to be able to go invisible as well. SO THIS ONLY PROVES THEY SHOULD BE INVISIBLE TO MIRRORS. They're always invisible and just make humans that see their aura see whatever they project as. This is where I'm nerdy: Mythos and gothic BY THE WAY, Love the channel and the show, it gives me tons of food for thought as a writer and as a nerd who likes to derail conversations.

The phone tree skit was beautiful

[@davekavanagh7599]

I hit that like button after that opening vamp extremely percussive P 😂😂

[@gaegesmith235]

Doctor Who actually has a great explanation for this. Vampires are actually alien fish that use a perception filter. A perception filter works by editing what the mind perceives. The brain has not seen the actual alien fish before so the perception filter doesn't know what to put in the reflection. So it puts what is behind the vampire/alien fish. And you get no reflection.

Kyle Hill and MatPat for department of space, science, and science stuff 2020. Let's make it happen!

[@raymondbarberjr2475]

About the Vampire Rant, the reason Vampires cast no reflection is that the myth is that mirrors show a reflection of our souls and since Vampires have no soul then there is nothing to reflect. So its a mythical/superstition thing, not a Science thing, but I like how you used science for your argument. In closing, love the show, keep it up.
