> he erroneously calculated yes. > Using the Minkowski metric the hypotenuse is length 0. Because It's on the null cone, yes. Two objects can have an absolute (invariant) distance of zero even though they are on different sides of the universe. That's the magic of pseudometrics. A long...

* I'm hoping this is a trick question on purpose, because nobody seems to have noticed the trick. * If a is at the origin, and B is on the unit circle, then the sides of the triangle aren't 1, they're sin(45 degrees) = .7 * While it is true that the metric is invalid because it's not...

That wouldn't matter. The point is, the units are wrong. To convert between time and space, multiply by c: MILES/HOUR times HOURS = MILES Real simple. You can only understand stuff by seeing the "simple."

would it perhaps be the volume of the bubble as measured by someone at rest inside it?

OP, pls answer this. I was all excited that I found an easy solution.

i know a great deal more than i let on. to trigger a discussion of mach's principle. i tried to do it without posting, "hey guys, whaddya think of mach's principle?" but everyone wants to either ridicule or be angry at me for asking the question. I don't care. I'm autistic. but that's BULL...

thank you. this is the kind of answer I was looking for, not yelling at me for asking the question. but I'm wondering how local curvature stops the space station from flying off when you throw a tennis ball at it. What does gravitation have to do with that? you can conduct the experiment in...

Supposedly, the retarded wave solution to Maxwell's equations applies to gravitation as well as electrodynamics. The space station doesn't fly off into the distance because every object in the universe (at whatever distance) focuses gravity through the mass of the station. Every object on the...
