The visible universe? Some back-of-the-napkin estimates are that no more than 2^500 bits will be flipped in the region of space we can see, but there's a crucial assumption about minimum temperature you need to make to make that that estimate finite.
On the other hand, there's some pretty compelling reasoning that the entire universe is actually infinite in extent, so ... infinite computational power?
- Houshalter 12y agoWhat an absurd thing to consider. There is no possibility of building a computer the size of the universe. This website is full of crazy people talking about crazy things!
- TeMPOraL 12y agoBecause? How do you know? Show us the reasoning. Also, there is this concept of "thought experiments". Building a universe-sized computer may sound as likely as sitting on the light wave and looking around, and yet the second one brought us Relativity.
