You have to pick:

I've got an eternity to think up something to pass the time thinking about. Better than nothing. :)

Umm... but you can't do anything. I doubt you can think of a way to pass the time that doesn't include thinking of ways to pass the time.

You have nothing to think about as there is nothing to observe. Or look forward to.

I'd go insane.

I'd go insane too,but then I'd get bored of that and go sane again.

Anybody realize that you are essentially God if you a formless consciousness that exists for eternity. You can't interact with anything tangible, but you can always imagine a universe.

@ jonathanost
Except you are not omnipotent. You are limited by your mental capacities. Sure you can imagine a universe, but it won't be real and you can only imagine a universe as good as you could do it right now, which is pretty limited in scope.

Whatever, I'm a Christian. The universe ending with me in it has a way better after party.

So I'm not a very capable god. I don't see any others around so that should be sufficient to satisfy me. Especially once I've gone mad. :)

In my opinion this is the worst option on this site.
