I apologize if this is in the wrong subsection, but I figured it was a physics learning material. Anyway, I've been reading the Elegant Universe, but found the Nova series quite helpful in understanding what the book is talking about. (I actually read part of the book, got confused, watched...

Assuming a tachyon exists, can one escape a black hole? Now, at the singularity of a black hole, gravity is infinite, right?* Since gravity is infinite, would it not suck in everything, even superluminal particles? On the flipside, since gravity can't exceed the speed of light, is it able to...

So, if Person A and Person B are moving away from each other they both perceive each other's passage through time as slower, but their own as normal. Got it. But... then neither one of them is actually moving slower through time? It's just how it's perceived? Now I'm more confused. I think...

Sorry I'm back after so long. A move, a loss of Internet connection, and my own low Internet availability... but here I am. I might be off then. Velocity is a direction and speed of travel, right? If the velocity of Something is the same, then wouldn't that Something be able to say it's...

New guy here with a question about Special Relativity and stopping acceleration. Forgive me if I have any of this wrong. I'm generally unable to follow physics for a long time before getting lost (I'm very right-brained--which means I'm artsy, not mathematical--and I've been told my brain can't...
