Some time ago, I watched a television documentary in which scientists claim the universe was created at the instant of the big bang, by a collision between two pre-existing universes.

With this idea in mind, I have wondered if the reason why a theory of quantum gravity cannot be found is because our universe is a hybrid universe, represented by two mathematical theories, wholly alien to each other,which can never be unified.

This is just a thought from a layman. Derek R Crawford.

Extra Dimentions.
I read with interest the theory that extra spatial dimentions exist. However, this view is at variance with one expressed by Professor Stephen Hawking who remarked that " if there were more than three spatial dimentions, the orbits of planets around the sun or electrons around a nucleus would be unstable and they would tend to spiral inward."
