Because of the relativity of simultaneity from special relativity which states that there is no absolute simultaneous events (i.e. "now")...
You're right, that's futuristic fantasy (not sure "science fantasy" makes any sense) and despite the way fiction is currently categorized, it...
I didn't say it shouldn't be pursued in the interest of exploring distorted space-time, but the plausibility of using it for actual FTL is...
In general, yes. Although it's possible to carefully construct scenarios where FTL doesn't allow for causality violations, any arbitrary use of...
I responded to the wrong post.
In that case you must also ban FTL.
I wouldn't exactly say NASA is taking it "seriously". Alcubierre published a paper in '94, and now someone is looking at using lasers to make...
Sure, as long as negative mass exists and you never want to interact with "normal" space-time again once the thing is switched on. "Ok, you can...
It ignores the fact that when you "push" on something, you're actually creating a pressure wave that propagates through the medium at some speed...
I know you touched on large-scale problems with gravitational theory, but I would like to point out that the galaxy rotation problem is really...
You're right, it does currently seem to require vast amount of mass-energy to distort space-time in a meaningful way, but at least we know it can...
So I thought of a highly boiled down simplistic method of contemplating why FTL communication via QE (or any mechanism) doesn't make any sense....
You cannot use entanglement to send information, period. To put it most simplistically, you need to examine both entangled particles to extract...
(It's about 3.0x10^8 m/s, not 3.6 :)) Is it more plausible that some sort of universal reference frame (hyperspace) exists, which would...
But your jump drive doesn't actually eliminate time travel unless you have some other restrictions in place on where/when you can jump. (This...
