Twin Particles 4 Replies

I viewed a short program about quantum mechanics earlier, and it metioned something about twin particles. It stated that in 1997 in Geneva an experiment was conducted where two photons, that were twi…

The Speed of Gravity 8 Replies

I was thinking? Does Gravity have a speed? I imply this question in respect to light, not the affective speed of a body under the influence of gravity. I understand that normally, the speed of gravit…

Comment by Hoffi on April 21, 2008 at 7:49am: Simple? All this covariant stuff and the index salad totally confuse me. I stick to quantum mechanic. Simple and beautiful. And nobody is expected to understand it.

Comment by ecidyalpsoeddog on April 11, 2008 at 7:37pm: It's Relatively Simple!

I've been studying Einstein's Theories of Special Relativity and General Realitivity this week, after a break of a few years. Oddest thing. 1. It now reads easy and straight-forward to me reading it now because I want to do it, and never did make a lot of sense before when I had to do it. 2. It makes sense! 3. It is no more involved than Newtonian Physics and adds little more. 4. Newton was prevented from achieving the same gold standard and conclusions only through his ignorance of 747's, motor cars, and rockets, otherwise he'd have nailed it.
