I second that.
Thanks so much Craig, for explaining it better!
Last week I was watching a recorded episode of Morgan Freeman's "Through the Wormhole" documentary, entitled "Does Time Exist?" Full episode
here. If you f/fwd to 39 mins (watch the whole doco tho, very interesting), one of the theorists (Lee Smoulden) is suggesting that time is older than the universe and goes on to explain that the laws of physics 13 billion years ago are different to the laws we know today. A cartoon demonstrates to photons travelling at the speed of light at different rates.
Quote (quoting both Freeman & Smoulden here): "Did space come first or did time come first. Physicists agree that the big bang created space, they don't agree on whether it also created time. There's a lot of people in physics and philosophy who think that time is an illusion, that's really true with the deepest, deepest level is timeless is outside of time and I don't believe that, I used to believe that but I've come to believe that time is really really real. Lee Smoulden believes that time is older than the universe, it was here before the big bang, and it will be here after the universe ends and he thinks he can prove it by looking at closely at how particles of light behave over long distances. One of the core laws of physics takes that light travels at 186,282 miles per second. If time is an illusion, then this will be true everywhere in the universe no matter where we look. But if time is real, it's possible that the laws of physics changed as the universe has aged. If a basic law of physics such as the speed of light doesn't hold true out in the oldest part of the universe, we'll know that physics has evolved since the universe was born. So time can't be an illusion."
Then goes on to explain the tests that Fermi is doing on gamma ray bursts giving us the chance to check out what the laws of physics as they were 13 billion years ago. Then goes on to show a little animation (at 42mins) of two photons travelling at different speeds after a gamma ray burst.
I watched that doco it seems in good timing with release of this news. Hmmm... so it appears we have to change the laws of physics for today.
Another great episode, "The Equation of Everything" actually shows an example of how two photons of light travelling at the same speed can behave differently when they are "watched". Have a look at 17 mins.
Doh, there is no YouTube Video for that one, it was a good too!.
Heavy stuff... As you guys know, I have a limited understanding of physics, but I do enjoy reading about it, learning about it and asking questions here.
