Hi, EA.,
Just got a note from Joe, saying that there is an interesting conversation going on here…
I think the subject we’re discussing is pretty interesting. But so many people have made so many complicated posts that it’s taking me a while to reply to all of them. Your post took an especially long time because you raised a lot of issues and because I like to look up the quotes people use to get a good idea of the context in which they were used.
** From Dr. Stephen Hawking**
In fact, the theory that the universe has existed forever is in serious difficulty with the Second Law of Thermodynamics. The Second Law, states that disorder always increases with time. Like the argument about human progress, it indicates that there must have been a beginning. Otherwise, the universe would be in a state of complete disorder by now, and everything would be at the same temperature.
The conclusion of this lecture is that the universe has not existed forever. Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago.
As I have said in earlier posts, different people use different definitions of the word universe. I agree with Stephen Hawking that the observable universe stated approximately 15 billion years ago.
Hawking does not say that it is impossible for there to have been something before the Big Bang, he merely says that it is currently impossible for us to know anything about that period:
"Stephen Hawking:
Since events before the Big Bang have no observational consequences, one may as well cut them out of the theory, and say that time began at the Big Bang. Events before the Big Bang, are simply not defined, because there’s no way one could measure what happened at them. This kind of beginning to the universe, and of time itself, is very different to the beginnings that had been considered earlier. These had to be imposed on the universe by some external agency.
He also explains the problems with the steady state theory and the oscillating universe theory. Both of these models are not consistent with our data. I agree with him that these theories are untenable. However, he does not discuss more modern cosmological theories. I am not sure exactly when this speech was made, but a lot has changed in recent years. Hawking’s collaborator, Roger Penrose, now recognizes that the cyclic universe model is a very viable contender (like me he realizes that we can’t currently
know what happened, but he recognizes that the cyclic model fits the data as well as any other).
The evolution theory regarding the formation of the earth has the same problems as the cellular theory. There is no beginning proposed by evolutionists that can be proven, just disproven. Where did the matter come from?
Why does the sun move around the earth? Why do the seasons change? For thousands of years, humans had no answer to questions such as these and assumed that they could only be explained by a supernatural being. We now have good scientific explanations for these. Fortunately for the families of scientists, there is still more work to be done, more that has yet to be discovered. Just because we currently don’t know exactly what happened, doesn’t mean that they must have been caused by God. On both of your questions, science has general theories about how things could have taken place, but we don’t yet have enough data to figure out exactly what did happen.
***“The Big Bang represents the instantaneous suspension of physical laws. The sudden abrupt flash of lawlessness that allowed something to come out of nothing…It represents a true miracle.” ***
(I thought the acknowledgement of miracles was exclusively a creation belief.)
Paul Davies, physics and evolution, The Edge of infinity 1995.
Suspension makes it sound like the laws were in place both before and after except for an instant in between. This isn’t quite what the old version of the Big Bang model teaches. And just because a scientist used the word miracle doesn’t mean that he meant the word in the same way you use it. Scientists often use allusions to God or a creator metaphorically. Both Einstein and Stephen Hawking talked about God and a creator in their works, but if you read their private thoughts on the subject, they both appear to be either agnostics or atheists.
But main problem with using this quote is that it is extremely outdated. His view may have been common in 1995, but quite a lot of recent research shows that an eternal universes is indeed just as possible as a universe that began in the Big Bang.
