Main propositions
The theory states several ideas and propositions, but to give a quick impression, these are the most important:
We are not being pulled towards Earth, but rather pressed against it.
Our universe is a perpetuum mobile.
The life of a universe
A widely accepted theory is that our universe originated in a Big Bang, a massive explosion that created the basic elements of all that exists. Also commonly accepted is that our universe has been expanding since the explosion (as you would expect when something explodes) and that it is still expanding as we speak. That may sound fair so far, but note that these are the only two things about the life of our universe that most people agree on. They are supported by scientific evidence.
Questions that are much harder to answer are about the period before the Big Bang and about how and if our universe will end. If all that exists was created in one massive explosion, then what was there before that? What triggered the explosion? When you think about this, 'nothing' may not sound like the most satisfying answer.
In Hoogenboom's theory it is described how the existence and collapse of a universe is a cyclic process. While our universe expands, it also cools down. This will eventually lead to one giant black hole that absorbs all matter. The black hole cannot sustain forever and will explode in a new Big Bang, creating a new universe.
