I only read the first few paragraphs, but stopped. The reason being that this guy feels vindicated because none of the big boys proved him WRONG.
In science, anyone can say anything is true, but it's your job to prove you are right. It is NEVER anyone elses job to prove you wrong. I submit Hawking didn't respond to him because he didn't see anything worth wasting his time on.
Okay, that makes sense. But, what if you are right and nobody agrees with you OR tries to prove you wrong?
