Wormholes might be theoretically possible. But safely traveling through them, let alone generating the energy necessary to create or sustain them, is currently beyond high fantasy.
Wormhole travel, if it's possible at all, is the end state of an unthinkably advanced civilization. To such an extent that it's not clear something that advanced would need to bother with traveling.
It seems to me like wormhole communication is much more likely, and even then you have to settle around them.
Even interstellar travel at slow sublight speeds is hundreds of years away. So, one step at a time.
My startup plans to deliver wormholes within five years. VC please.
we will never go faster than light. these clever little ideas like wormholes and shit are a pipe dream.
you cannot violate causality. end of.
I mean, have you looked into quantum entanglement?
It's experimentally proven to violate either locality(speed of light) or realism(cause and effect) and it's still kind of open to interpretation which it does.
Quantum micro effects don't translate much to macro systems.
Yeah, like photos are gonna do whatever the fuck they want in entangled circumstances, they're weird little guys.
Putting, say, a 1/4 km ship with thousands of tons of mass into a wormhole is a different story.
You cannot accelerate that much mass to c, and you cannot open wormholes close enough to each other so it can eat out its own asshole (violating realism if you want to be boring about it I guess.)
For things that matter, c and realism are da law. There's no way around it.
Fully agree that if there's ever effectively FTL space travel it probably won't involve chucking ships through wormholes or accelerating them to c.
I wouldn't be shocked if someone came up with a theoretical basis for weird frame of effect/space bending BS or information teleportation + ridiculously detailed fabrication FTL. Also, while it's true quantum phenomenon don't percolate up to the macro scale that much on their own (anything that does isn't considered a phenomenon, just the way the world works) they do if you force them. 100 years ago maybe 10 people in the world knew what an entangled bell state was, now we're building super computers based on them with processing power of 2^n for every n bits which is likely to have an earthshattering effect on the everyday individual sometime within the next 20 years. I wouldn't say never with regards to some form of FTL exploiting a similarly weird effect noone really knows about yet.
Quantum entanglement and non-locality do not violate the speed of light.
Assuming you have a particled entangled to some other distant particle, there is no measurement that you can make in your particle that can make the other particle behave in a way that would transmit information.
An analogy would be 2 entangled coins, the entangled "condition" says that if one coin is heads the other must be tails, vice versa. You separate the two coins and your coin get tails
However there is no way for the guy on the other coin to know whether his coin is heads, unless you go over there and tell him that you got tails, this act of communicating ur result would obey the speed of light, therefore speed of light is still unbroken

Thanks for the link :)
I'm aware of the no-signalling and no-cloning theorems. While the violation of the Bell Inequality may not allow superluminal signalling the hidden variable model (as in the coin allegory allegory) has been conclusively disproven and violation of the bell inequality does require superluminal information transmission.
