@molle2575منذ 3 سنوات Ok. I have read "To Sleep In A Sea Of Stars" by Christopher Paolini. Amazing book Well, obviously it's a sci fi book, so not actual sc id="hidden30" class="buttons">ience. However, Paolini has always been great at doing research on topics before writing about them.
Paolini has in his book created a FTL drive for his ships (Faster Than Light). As I have understood the whole thing (as english is not my native language) the FTL drive creates a "bubble" around the ship (Paolini calls it a Markov bubble). Then the ship remains stationary within that bubble, but the space in front of the bubble is compressed and then behind the bubble the space is again expanded. So the ship itself remains stationary, while moving through space.
I have heard thise theories mentioned elsewhere as well, so I imagine that Paolini has too. Now, aside from the fact that we don't have the technology or any way of producing the energy needed for such thing, is it theoretically possible?
At the end of the book, Paolini has even made up some science papers explaining how it all works, but that went somewhat over my head. I read along in the book, while listening to it at the same time to improve my english. ....وسعت

@KyleNallyمنذ 3 سنوات I think you've done a video about this, but what about the Alcubierre warp drive?
For the uninitiated, this hypothetical drive encloses a 'bubble' id="hidden50" class="buttons"> of 'normal' spacetime between a trough and a peak of gravitationally warped spacetime. Our spacecraft, situated exactly between these two warped regions, stays in the center of that bubble. The trough is projected in front of the craft and the peak is projected behind. As these move, the craft also apparently moves. The kicker here is that there doesn't seem to be a speed limit in Einstein's equations for the movement of spacetime itself. Mass is not being moved; the spacetime in front of and behind the craft is being warped instead. Within its bubble, the apparent velocity of the craft and everything in the bubble is zero but, to an observer that is at rest relative to the craft, the craft has an apparent FTL velocity.
I hope I got that right. It's been a while since I read the original paper. According to everything I've read about it since then it's the one viable way to achieve FTL travel and does not violate relativity. ....وسعت
