Rethinking Einstein: The end of space-time http://www.newscientist.com/article/mg20727721.200-rethinking-einstein-the-end-of-spacetime.html interesting read...
I'm real interested to see what Michio Kaku has to say on the matter, he is after all and imo, one of the leading theoretical physicists on string theory. Personally I cannot make a judgment on this without any mathematical proof and it's far from my expertise in the physics field. The theory seems new and fresh which gives it some appeal, but I'm unsure if it will stand any amount of time.
That hurt my brain a bit, but I got the general idea. Pretty interesting for sure. I doubt we will be able to observe super massive black holes anytime soon though ._________.
Technically we can't observe black holes, because they are invisible. The way they are seen is through doppler shifts and we currently can estimate quite a lot about them now including their mass. What we don't know, and won't know until we get close enough, is what happens to the matter that they take in as a base rule of the sciences is matter cannot be created nor destroyed. The Supergravity theory states that, since gravity is actually the strongest force in existence, yet we can stand on earth, is that gravity holds all realities together and is thus spread out and split up between each individual reality. With this in mind the gravity in a black hole is infinite, thus giving some evidence of their being more then one dimension. String theory states, and this was hypothesized by Hawking, that if one were to see someone go into the event horizon of a black hole they would be disintegrated, mangled, and killed in the most horrendous way, but if you were that person going through the event horizon you would be completely fine. The idea of splitting up time/space to view how we see the universe is more of a different approach of implementing solvable mathematical solutions to the universe. String theory has been around for about four decades and has yet been able to do that, hell their was a huge debate in the physics community on whether their was 10 or 11 dimensions. Just glancing over the article I think we know that time and space are intertwined and that's what most of Einsteins theories conclude. We actually don't have a definition for time as it's how we perceive it and not universal. The article seems to be focused on time/space yet the actual theory involves the variable of cooling/heating particles to effect particle movement, making it a totally different concept. Lorentz symmetry already dictates a standard for measuring time and movement throughout it. The real meat of the theory proposed is the heating and cooling of the universe in it's movement which varies in speed and this has been noted. I'd be interested in seeing the quantum gravity equations that he came up with and I'm sure if this theory holds any merit I might see it in my curriculum in the coming years.
Yup, even if it holds true it could be decades before it's made the standard theory for quantum gravity so until then Einstein is in all respects, right.
