Scientists devise test for string theory

That's what I was going to say.

So does string theory account for / explain this?

That's the problem w/ string theory it has made no predictions that can be verified by observation or experiment, hence the significance of the Wisconson teams predictions

The latest version of string theory is M-theory

It will be interesting to see if the new 20 mile long CERN electron/positron SUPER super collider being built near Geneva can produce any interesting observables.
It will reproduce conditions of the Big Bang at 1 trillionth of a sec old.
At a cost of 6.7 billion $ and 13000 person years of labor.

Can't wait.

+1 for the elegant universe. saw it once on pbs i think and it blew my mind, but i could follow it.

+2. I actually bought the book after watching the DVD (have that, too). Haven't read the book yet...

When it was theorized that the rate of expansion of the universe was decreasing, I pondered that perhaps it will eventually come to a stop, then begin contracting toward its black hole origin at ever increasing speed until achieving infinite mass resulting in another big bang starting everything over again.

Now that it's theorized that the rate of expansion of the universe is increasing, I ponder that perhaps it will eventually achieve infinite mass resulting in another big bang starting everything over again.

When it was theorized that the rate of expansion of the universe was decreasing, that seemed logical because after the big bang, accelerative force ceased and the decrease in acceleration was caused by the large gravitational pull of the black hole that the big bang had created.

Now that it's theorized that the rate of expansion is increasing, I ponder that perhaps the big bang is not over but rather still releasing energy causing continuing acceleration of the universe until it will eventually achieve infinite mass resulting in another big bang starting everything over again.

DAY LATE $$$$ SHORT ON THIS ONE...I reported on this awhile back.

Sorry Tabs -- I missed that. I was going to post it when I first read it a week or two ago and got tied up with other things, like work. I just worked down that that note again and thought the folks here would find it interesting.
