Hi All,
First question so please go easy on me.
I'm currently reading 'Why Does E=mc2? at the moment and in an early chapter, Brian Cox referers to The Eather and how daft the concept was because it would cause drag in the universe and planets would lose orbital momentum etc, etc.
Now...
Gonna be flippant on my very first post.
I reckon there is a big brick wall made out of dark matter encircling our universe. Then when a galaxy hits the wall the energy passes through it to create a big bang on the other side and therefore creating another universe!
Then I woke-up!
