I found this showing the math behind it - http://www.reddit.com/r/theydidthemath/comments/1x50xl/time_and_energy_required_to_bruteforce_a_aes256/

With a billion GPU's "The universe itself only existed for 14 billion (1.4e10) years. It would take ~6.7e40 times longer than the age of the universe to exhaust half of the keyspace of a AES-256 key." So guess a new universe could be created before this happens.

thanks for your research, it's a good link and answers my questions

unfortunetly it is impossible.

It's not impossible, but it is highly improbable.

It's the way people look at this....
Someone who looks realistically to this topic says it is impossible.
Someone who say it is possible looks in a theoretical way, like a scientist for example.

I would say both answers are possible and acceptable as long someone can explain why he give this answer.
