He sounds like an ignorant idiot. But does have some great theorys. How can you prove the existance of something that exists outside the universe?
WGDE strives to show that there is no God, no miracle, no supernatural explanation for the workings of the Universe as claimed by General Relativity, Quantum Mechanics, String Theory, and traditional religion. WGDE holds that Big Bang is a creationist theory in disguise, nothing more than a veiled way of selling God. Big Bang is, as Christian apologist William Lane Craig says, just a stealthy form of Creation ex-nihilo. That's why 'scientists' such as Jastrow and Sandage today help individuals such as Craig spread Christianity, while pseudo-atheists like Hawking and Davies spend their time apologizing and creating excuses for why they don't know.
If you are open to new ideas and want to have a fresh look at science, specifically the physical workings of light, gravity, electricity, magnetism, etc., WGDE provides you with a rational alternative. You will never listen to a mainstream mathematical physicist again.
