- ncmncm 4y agoMy CPU can't, but it is theoretically possible to make a CPU that could.
- plasticchris 4y agodo you mean that a turing machine can't simulate the universe but some other kind of cpu (i.e. quantum) could?
- jhoechtl 4y agoThis is all very theoretical so ... a turing machine can simulate a universe as it assumes infinite memory
- ncmncm 4y agoNo, I mean that it is physically possible to perform an unlimited amount of computation on a fixed amount of energy, if you are willing to wait long enough. Nobody has built hardware that has this property.
- NathanielK 4y ago1W is one joule per second. With unlimited time, you also have unlimited joules trickling out.
- ncmncm 4y agoYou are not getting this. You can do an unlimited amount of computation on one joule. One watt-second, if you like. Not an infinite amount of computation, but any finite amount.
