Actually, I saw a show on this last night, but I was simultaneously on the computer, so I didn't get all of it. Anyway, apparently they were studying supernovas as a "cosmic speedometer". I don't know how they do it, but all supernovas are pretty much the same brightness, so they figure out the distance, and the rate its brightness is decreasing, and figure out the speed of the expansion of the universe. Now they know that it's going faster than it previously was.
yeah we need to learn more about dark matter and dark energy ... let's hope we can detect gravitons soon..and see a whole new exotic layer of our reality seems Einstein was right about his 'cosmological constant'....poor guy so far ahead in his thinking he was alone..and began to think it was the 'biggest blunder of his life"... i hope somehow his 'wave' parts flow on and see we are FINALLY understanding his wonderful thinking
Can anybody explain what is the observational evidence for accelerating expansion of the universe? From the brightness of distant supernovae.
Really? They are? I had never heard supernovas used before, rather suprnovae. Well, I guess you learn something everyday. Thanks.
