Turing machines are widely believed to be universal, in the sense that any computation done by any system can also be done by a Turing machine. In a new article, researchers present their work exploring the energetic costs of computation within the context of Turing machines. (1)

Try to think.

Does it matter how much energy you spend?

At the end, everything turns to heat.

Lost in the vast space into nothingness.

And every thought will turn into nothing.
