This is really bothering me... (Physics)

[Tread]

What is possible and not in astronomic dimensions, is a bit like to speculate. We know nearly 5% of the composition of the universe, the visible matter. No one realy know what dark energy and dark matter is, but in the currently theories they must exist. Even the origin of mass is unknown. It must be the higgs boson, but it's never proven.
There are more questions about the universe then answers.
