New Theory for the Big Bang
It is now commonly accepted that the “Big Bang” theory for the creation of the Universe is correct. It is now even accepted by the Vatican.
The problem is however, that the current theory that, at first everything existed in the size of a pea. There was a big explosion and the universe was created and kept expanding until it reached the size it is today, and is still expanding.
This theory however cannot explain gravity nor can it explain the existence of dark matter and dark energy. As the universe continues to expand, it is now considered that we have only, as yet, found 4% of matter that exists in the universe. That is why they name these, as yet undiscovered entities, dark matter and dark energy.
As well as the unexplained existence of these matters, the current understanding of the big bang, is also dependent on an as yet unproven “inflation theory”.
Theoretical Physicists, Paul Steinhardt at PrincetonUniversity and Neil Turok at CambridgeUniversity, are now studying models for a new theory for what is known as the ekpyrotic universe.
This “cycle” theory is that the universe is split into different “branes” or sheets. Once ever trillion years or so, these sheets collide. These collisions would cause results similar to those of a big bang. However this new theory can explain the inflation theory and the existence of dark energy and dark matter, as well as gravity.
This cycle theory would mean that the universe is ageless and keeps being reborn.
Personally I like the second theory. However it does have one disadvantage to the first. With the first theory, it is possible to estimate when the universe will cease to exist. With the second theory there is no way of knowing when the next collision may occur.
