Re: FTL astronomy

Nice observation about c being constant, what's more important is meter definition relying on it as per SI 2.1.1.1 so we would no longer have our current way to measure distance if c became infinite. Well, we could go back to iron stick meter prototype and Michelson-Morley experiments.

Re: What if instant teleportation was possible

Aha, but this you require throwing out something we have good reason to believe is true is just a matter of interpretation. "Throwing out" is one way to look at it, another is just "extending the equation" in a way that it normally holds and is broken only under some weird condit...

This remind me about that guy who wrote a paper about physics of Magneto in XXX movies, and how he was supposed to shine moving heavy things around. Imho this is taking these experiments one step too far but, neverless, still amusing.

Good deal of content produced by humanity has no basis in reality ) In one word: imagination. Or do any of these papers have any more real basis? Yet, people keep thinking about it.

Re: What if instant teleportation was possible

Your version of teleportation doesn't seem instant, however, if your test subject is seeing things twice. he does so because he moves faster than light - so in effect he sort of "time travels" and experience same events again. ps - if we would instead move the guy exactly at c, he would s...

What if instant teleportation was possible

So I decided to post here in the memory of good old days, right. Not sure if you guys are up to discussing this kind of stuff these days, or if you cooked some stupid rule that forbids it, but anyway - join me in this thought experiment. Imagine that instant teleportation is possible. Take the simpl...

what date it is now on the Moon?

Does it have time zones like Earth, or does it use UCT time or whatever? Any international agreement on this, maybe?
