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.

It would also kill the traveler at the beginning of the travel and then create a replica on the other side. Doesn't Heisenbergs uncertainty principle prevent us from creating anything like a teleporter?

[@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.

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.

[@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.

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.

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).

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

[@MrTripcore]

That's how quantum gravity works in my opinion

[@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.

13:09 but i think that plank scale wormhole will only allow you to travel in space-time in just plank scale which is not sufficient

[@zizimugen4470]

2:50 wouldn’t the animation be more accurate if the wormhole were straight and spacetime were curved for the “normal” distance?

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?

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.

If you had two wormholes connected in the same spacetime and pulled them apart. At some point the distance would match c and they'd become indistinguishable to normal spacetime. Can wormholes be thought of as simply a voliation of c?

[@HI3Enjoyer]

Hi, I'm kind of new to the topic here... So, this might sound dumb. But what would the temperature inside a black hole be? I learned some time in school that compression causes molecules to collide, causing an increase in temperature. Since the black hole is a bunch of mass that's extremely compressed, how high might the temperature be? Also, since light is also trapped in there, does that also increase the temperature inside? Or is it just cold? Maybe the reason that the surroundings of the black hole is cold is because the heat inside cannot escape because there is no matter that can escape to transfer the heat energy outside of the black hole...

Jokes aside... have we 'rabbit holed' ourselves with 'exotics' .. and impossible unexplainables?

[@helicocktor]

"Exotic" simply means an object with specific mathematical properties that we either haven't found yet or simply doesn't exist. We imagine that object (eg. particle) and give it its properties on paper to fit a purpose, that's it. Theoretical physics territory. What it is is basically conjecting, for example; "what if an electron posesses property z instead of x as we see, and how would it interact with the real world?" Object like particles with negative mass are completely theoretical and only exist on paper to our current knowledge. Imo, we haven't rabbit holed ourselves into impossibilities, it's just that testing our theories becomes harder and harder so we need to come up with models to fill the blanks very specifically, and test for that effect instead. Some of these theories may be impossible to test with our current knowledge, but may be a very real possibility in the future.

[@matrixarsmusicworkshop561]

@@helicocktor That. Just like "black matter" which states matter but is really just and equation...

[@helicocktor]

@@matrixarsmusicworkshop561 if you're referring to dark matter, dark matter is very real and we see its effects very clearly. From how clusters of galaxies clump together to how spiral galaxies spin, we see the effects of it. Dark matter is just gravitational energy that's unaccounted for, but we can quantify its strength. The theoretical bit is what it's made out of, but we do know that dark matter is very real.

The description you gave for exotic matter sounds eerily similar to an element in a documentary on netflix. It's called Bob Lazar Area 51 something if you wanna see it
