The Universe does not exist:

Because of cause and effect a steady universe is impossible and a big bang universe is impossible, too.
Without a starting point the universe can not exist and simultanously there can't be a starting point.
It is ridiculous to say that time and existence suddenly came into being, because it implies that there was something before time and existence,
but there can be no before without time and no something without existence.
In the whole, all we measure (electric charge, angular momentum, mass energy) adds up to/cancelles out to exactly zero.
There isn't any net electric charge or angular momentum.
The worlds positive mass energy is exactly cancelled out by its negative gravitational potential energy.
The universe is in itself nothing. Energy in total is zero. No process creates or destroyes matter. The universe does not exist.
The universe does not exist right now.
This text has never been written.
The question about the existence of the universe is the question about existence and not about the universe.
Existence equals cause and effect.
You can not define existence by anything else. Everything needs a cause to exist.
The no-cause universe (steady galaxy) does not exist and the no-cause universe (big bang) does not exist as well.
You can not create existence.
Existence is impossible.
The universe does not exist.
Existence is a negation in itself.
We cannot say that anything exists, we can only say that everything does not exist.
