It may seem strange to think something can survive even the death of the Universe, but that could actually be possible as a result of the laws of quantum physics.

Scientists are now suggesting a new blueprint for a device, known as a time crystal, that can theoretically continue to function as a computer even after the universe cools to absolute zero.

Ordinary crystals are three-dimensional objects whose atoms are arranged in regular, repeating patterns similar to table salt. They adopt this structure because it uses the lowest amount of energy possible to maintain.

But if crystals, such as table salt, could be translated into the fourth dimension of time.

Wilczek theorizes that a working time crystal could be made into a computer, with different rotational states standing in for the 0s and 1s of a conventional computer.

"To make it interesting you want to have different kinds of ions, maybe several rings that affect each other," he says.

"You can start to think about machines that run on this principle."
