The best way to survive going through a wormhole is to install a teleporter device on either end, then just send the teleporter data between the sides. This also greatly reduces the amount of exotic matter a space traveler needs to make in their particle accelerator.

On a serious note, a galactic-scale pandemic is pretty much impossible, because of vast distances and time periods required to travel that far.

You would create the wormhole with specific destination in mind.

[@garethdean6382]

A wormhole's exit has energy and thus responds to gravity. You can 'tow' it behind a large mass (Or if the energy is negative, push it). Similar ideas have been mooted for moving asteroids or small black holes. Of course if the wormhole is very massive you might have to move a star to shift it.

I agree. It's one thing to know the subject matter. Being able to explain it in a way that non-experts can understand it is a completely different skill. I have a M.S. in Marketing Communications, but I love learning about space and my childhood dream was to work as an astronomer for SETI. My former best friend got her PhD in molecular biology. She had this ability to break down complex knowledge into easy-to-understand explanations. I told her that was an impressive skill to have and she could use it in a variety of ways. Unfortunately, she was so worried about making her future in-laws like her, she did a complete 180 on her personality and now she's a pretty hateful person who believes in religious conspiracy theories peddled by her in-laws and social media rather than actual science. It's very sad.

Agree with you dude, they really should rename this channel something like “sci-fi debunked” as that’s all this guy ever talks about! But I wouldn’t worry, they are constantly proving and disproving things, some people like to believe we are the night of scientific understanding, but if you listen long enough, they all say that what we know about physics is barely scratched the surface. One thing he said though is completely true, it will be hundreds of years though before we actually have any concept of the real story. Human kind will (if we make it through quarantine) crack faster than light travel, in every century you have the nay sayers who say “man cannot fly” and “man cannot travel into space” because they apart her shady believe they know matter of factly it’s not possible, with all the “scientific” evidence to back themselves up, but it’s the dreamers who find the way for everyone.

[@captindo]

Well, most scientists of the day thought the Wright brothers couldn't achieve flight because, well, ignorance. Really think about it, nature refuses and we create and over come, and, as a species, we will figure out space travel, just like the explorers of old sailing into destiny, we will as well.

[@TheSaneHatter]

Here's a compromise theory to suggest: while your "not even light can get through" comment seems to put the kibosh on it already, is it possible to employ or create wormholes so that, if not physical matter, at least INFORMATION can get through? If that's true, then wormholes could at least be used as a fast means of interstellar *communication*, rather than travel. (I'm thinking of Reg Barclay's "micro-wormholes" from "Voyager," of course.) Also, if a wormhole could be identified, and the other point somehow located, could they be used as a means for navigation, as opposed to propulsion?

[@transient_moonlight]

Information can't travel faster than light, though, since the speed of light is the speed of causality.

[@stewiesaidthat]

@Moonsong causality is instantaneous. It's the effect that travels at the speed of light or sound. The layer of the universe that you exist in is defined by energy. Electromagnetic waves are the fastest anything can travel within that layer. The speed of an electromagnetic wave is dependent on the energy density of the region of space it is traveling through. To travel faster than light, you just need to cross over into the next layer. Similar to how a fish out of water can fly faster through the air than it can swim in the ocean.

[@jish55]

Probably my favorite explanation to wormhole travel is to think of traveling from point a to point b in space as one very long line, but figuring out wormhole travel would essentially take point b and put it next to a, essentially removing the necessity to travel from one area to another in extended periods of time.

Draw objects on a piece of paper with a pencil and let that be the two dimensional plane, start drawing over and over with the pencil on a small part of the paper and gradually that part becomes darker and darker. After concentrating the drawing in one spot, eventually the pencil markings will start to form a bump and that's now the two dimensional object gaining access to a third dimension (because the slough from the pencil has become so concentrated it has no where to go but up in height). I like to think of black holes the same way which leads me to think they represent the intercept of a third dimension with a fourth dimensional plane.

Off topic here, but could dark matter simply be matter that is "suspended" in a higher dimension, thus making it impossible for us to see it, but still able to affect us gravitationally?

[@MrTripcore]

Correct. Dark matter is 2d energy suspended in our 3d space

[@MrTripcore]

It's able to rotate in 3d allowing it to produce gravity

[@MrTripcore]

It's suspended because relative to our 3d world, it's slowed down from our perspective due to its velocity - similar to how we observe black holes

[@MrTripcore]

The reason why we don't see dark matter is because it's 2d and doesn't directly interact with photons Photons essentially bounce off dark matter in the direction that dark matter is spinning/rotating

Honestly, I think the more pressing question is whether wormholes will allow fast internet speeds. In some of those massive computing clusters, the speed bottleneck is literally the speed of signals through wires (or, in some cases, through fiber optics. Eventually, we'll end up with a situation where even the speed of light in a vacuum (rather than glass) becomes a bottleneck. General-purpose quantum computing can alleviate SOME of that (not because signals travel faster than light but because of how quantum computing actually does computations), but not all computations benefit from quantum computing and you'll still need a classical computer to interpret the result.

is dark matter constantly falling into black holes? making them grow w/o any evidence for the BH feeding (besides gaining mass)

[@samsungtelevision695]

TheRolemodel1337 this is a great question. I’m not a physicist but to consider the converse, it’s hard to imagine how all dark matter could avoid black holes right? Hopefully some qualified commenter will jump in.

[@tabularasa0606]

No, apparently Dark Matter only generates gravity but is not subject to it. I believe Matt explained it in an earlier episode.

[@Drkwll]

@@tabularasa0606 no, dark matter is subject to gravity too.

Matt, you are a global treasure! (And I hope that I am not too specific in this case regarding any interstellar future)

[@blackmage-89]

In Stargate SG-1 the gate actually sends information of what has passed the event horizon (of the gate) to the other side, not the actual matter. In fact there's an episode where one of the main characters actually remains in the buffers of the end gate after the first one is destroyed during the connection. Maybe sending information might actually be doable even with the negative energy constraint.

So Matt, I have a question for you. How does spacetime in the same universe overlap? Isn't the universe flat, and shouldn't this only be possible in a universe with positive curvature?

Casimir effect doesn't necessarily produce gravitating negative energy. Although its vacuum energy interpretation is famous because of its use in a lot of wacky works, it can also be explained as a Van der Waals-type force between the plates. There is a great paper on this topic by R.L. Jaffe from 2005 that really should be more widely known. As for exotic vacuum energy, it's often seen in QFT in curved spacetimes, though mostly on small scales where it can't really affect spacetime curvature (except in black holes, but that's a whole other story).

Gravitons are a wave function that expands at the speed of light like a ripple. You can come up with a GUT based on that observation.

According to the US DoD theres several forms of teleportation ones unknown and ones exotic, a thin sheet of negative energy. It says one can bounce you outside of the universe and since you cant exist there you bounce back.

Wormholes are weird. I miss the days when wormholes referred to something a worm did in your garden. lol Now we use the term to refer to something scifi sounding. I luv science.

Can wormholes exist without black holes ie without event horizon.

[@SimpleStory95]

This. How do you connect space to space, without using any space?

[@magnumpolmatier8184]

Kevin Story I would guess it depends upon the shape of the actual universe. If it’s flat I don’t understand. If it’s more of a huge sphere or torus I would imagine you are falling towards the other side with gravity assisting for half of the fall. You would have to break free from a black hole on the other side though. That’s my best understanding though. I’m no astronomer

[@SimpleStory95]

@@magnumpolmatier8184 Interesting, think of all the forms a 3d space could make in higher spaces (6,7, more?). What dimensions, measurements, etc does the 'space' 'containing' the universe have, does it 'exist'? Are they determined by the intrinsic properties of our universe, or the other way around? Not really science at this point but very very interesting.
