Only if you believe in hell !

I rather doubt it...

You didn't ask, but i'll offer some advice anyway; don't put that book down, read it all the way thru with as little breaks as you can. I've tried reading it 3 or 4 times, every time i'd have to stop and do some menial task, and get distracted, and by the time I got back to the book I was totally lost and had to back up a chapter or two to figure out what he's saying.

great book, but you REALLY got to pay attention and focus on it and nothing else.

basically

You might go mad.

There's no hell to go to.

Yeah, but only temporarily.

If you do, you will be in good company. Mark Twain, Hawking, Einstein, Sagan, and many other interesting people. Heaven? Ugh. Do not want.

I didn't.. or at least, not yet

Eternal damnation for reading it seems unlikely... The Vatican has been downright progressive of late when it comes to Cosmology. I can think of three reasons, though, that might earn you an indefinite term in Purgatory -- First, you might read it, misunderstand it, and proclaim it to be the work of Satan and his minions. Second, you might read it, misunderstand it, and proclaim that the Earth is both flat and the center of the universe. Third, you read it, think you understand it, and declare that it proves that Aliens visited the Earth in 1942 and impregnated Hawking's mother with a non-viable Human / Alien Hybrid.

You're already going to hell. Read on.
