I'm looking for a quote I read a few days ago by a famous quantum physicist, I can't remember which one unfortunately. It went along the lines of attacking "soft" science like sociology, psychology as masquerading as real science when really it's not. Basically hard vs soft science. Does...

Yes the clock would be ticking slower, but has time really slowed down or is the hand of the clock just moving a further distance through compressed space than the other clock? Right down to electrons and stuff, could they simply be traveling a further distance through compressed space but...

What I mean is two routes the same distance in overall space. Like two routes on Earth when looking down from above, except one route goes over a hill. You can't see the hill when looking at the 2D route. They are going the same distance but one guy has to go over the hill so is really traveling...

Two people leave from parallel points in space and head to other parallel points the same distance apart. Person 1 travels through empty space outside any gravitational influence, and it takes him 1 day to reach his destination. Person 2 comes close to a black hole on the way. It takes him 10...

In Brian Greene's article The Time We Thought We Knew, he writes: "Were you to board a spaceship, head out from Earth at 99.999999 percent of light speed, travel for six months and then head back home at the same speed, your motion would slow your clock, relative to those that remain...
