Re: big bang problems

Wasn't it who wrote:
I was listening to a lecture yesterday by Dr DeGroot who is an
astronomer and has served in several observatories.

He looked at the strenths and weaknesses of the theory, and
essentially in order for such a big bang to work there are very finely
tuned things that need to take place.

1. the creation of positive and negative particles must not be equal
or they would cancel each other out. But even if there was an
imbalance it is under a very limited scope, too much or too little and
it doesn't work.

2. the size of the explosion must be just right, too little and the
universe collapses and too much and it is too dispersed.

He quoted some figures, I think one was 1 in 10 to power 40 and the
other was 1 in 10 power of 60 which gives some idea of how finely
tuned it would be to have a universe.

Then there are other finely tuned factors to that the elements needed
for life could be formed.
So when you put it all together, it suggests there must be intelligent
design involved.

Also as we look into the distance we may be looking back in time, but
there is a limit to how far we can see, then we rely on theory, but
even theory cannot go back beyond the intital microseconds of the
beginning. There a theoretical barrier which prevents an answer.
So in effect we don't know how it all began.

Some recent theories suggest that huge numbers of big bangs of different sizes are happening all the time, each creating new universes with different matter/antimatter ratios and other factors. The vast majority of these universes are unsuitable for life, but there are so many of them that a few end up with just the right conditions for life to be possible.

M-Theory suggests that a big bang occurs whenever two Branes collide. It may well be possible to test M-Theory when we develop the technology to detect gravity waves, because gravity travels between Branes, and big bangs occurring in nearby branes should be powerful sources of gravity waves.
