Why would FTL travel break causality, as oppose to the relative time reconciling as in the Twin Paradox? [duplicate]
I have heard that if faster than light travel were ever made possible, such as by an Alcubierre drive, the user would be taken backwards in time, violating causality.
This is odd to me, as it already ...

Theoretical question on frames of reference
Some friends (all engineers - not scientists) watching Star Trek and discussing the science behind it. Not whether warp drive or aliens or anything like that were real.... No our discussions were on ...

Warping Space Time By Focusing on Getting Smaller Rather Than More Energy?
So all energy/mater warps space-time, right? However, whenever we talk about the human manipulation of space-time it is a far-off goal requiring nothing short of tremendous amounts of energy and ...

No FTL information implies no FTL travel?
The general consensus in the scientific community is that it is impossible to transmit information faster than light.
There is also speculation that it might be possible to open wormholes or travel ...

"Warp-drive" thought experiment
Why wouldn't this "warp-drive" work? Assuming we can build a flywheel that can survive near light speed and have an onboard power storage or beamed energy that can spin it up to that speed and back ...

Does a mass gain inertia against movement in all directions as it approaches the speed of light?
If a mass moves along the x axis at near the speed of light, does it take as much energy to additionally accelerate the mass along the y axis as it does to accelerate it along the x axis by the same ...

Doesn't Warp theory violate causality? [duplicate]
I have heard many physicists (ex:- Michio Kaku) saying "Warp speed" from Star Trek doesn't violate any known physical laws. But doesn't it violate causality?
Say, we make warp drive possible and ...
