Question:
Big Bang Theory

What things do we have that support this theory? Where does it come from? And is there evidence that is going against the theory?


Replies:
The major support is that we can detect the expanded and cooled photons from the earliest history of the universe. The temperature of this background agrees with the calculation of the big bang. Many other conditions like the amount of certain elements are also in agreement. There are always people looki ng for changes in the details, but most scientists find the data very convincing that it existed. on the other hand..recent measurements of the Hubbel Constant put the age of the universe (according to the standard Big Bang theory) *younger* than the oldest k nown stars (or is it galaxies...?)

Personally, I have no doubt that the standard Big Bang theory will have to be modified: physicists hate mathematical singularities that are supposed to have a real, physical manifestation. The theory of Black H Holes solved the problem of gravitational singularities, but I'm not aware of any "Big Bang-like" theories that deal with the singularity at cosmological time = 0
