General relativity makes no prediction as to what the vacuum energy density is. Give us a break!

It's only at the macro level where entropy comes into play that you can distinguish somewhat between forward and backward. In another universe, if the time arrow were reversed from our own, then we would be calling that time direction the forward direction. Yousuf Khan

My dear Pilgrim, you have just now discovered why nobody takes you seriously. Instead of engaging in discussion, you just put up your defenses, spewed irrelevant gobbledygook and began name-calling. You'll have to wait another several months for somebody listen to you again. Yousuf Khan

You express & parrot fantasies of deranged Jews and abberant goyim kikeophiles. There is not a singe instant where, in the local, testable neighborhood, humankind has been able to accelerate any ponderable body, bigger then atoms to relativistic speeds. -- Consider, there are N_A, 6E23 atoms needed to produce a handful of dirt. That's the amount of mass needed to produce a real solid ~5" disk... for which your relativity fails pitifully... > At least, you should toned your parroting down & said: To a (stationary) observer (outside the speeding frame) CBK processes may, perhaps, APPEAR to be slower. > Also, Youssi, don't tell anybody that you can't be really sure what happened because of it's relativistic speed, that the disk went by you... Except that its hypersonic boom knocked you out of your chair, and that you are ever more grateful that the relativistically speeding disk did not hit you head on.... ahahahaha.... > Of course, like all Einstein Dingleberries do, you may loudly disagree & prove your notion by simply providing the address of, and an interview with, Einstein's Younger Twin... Thanks for the laughs, Youssi... ahahahanson --- news://freenews.netfront.net/ - complaints: news(a)netfront.net --- |
