    Yep, you heard it here first. This clock will still tick even after when our Universe is obliterated!

    4D baby! Who's your daddy?

    =============================================

    The idea for an eternal clock that would continue to keep time even after the universe ceased to exist has intrigued physicists. However, no one has figured out how one might be built, until now.

    Researchers have now proposed an experimental design for a "space-time crystal" that would be able to keep time forever. This four-dimensional crystal would be similar to conventional 3D crystals, which are structures, like snowflakes and diamonds, whose atoms are arranged in repeating patterns. Whereas a diamond has a periodic structure in three dimensions, the space-time crystal would be periodic in time as well as space.

    The idea of a 4D space-time crystal was first proposed earlier this year by MIT physicist Frank Wilczek, though the concept was purely theoretical. Now a team of researchers led by Xiang Zhang of California's Lawrence Berkeley National Laboratory has conceived of how to make one a reality.

    Cool, I think. But what is the point if the Universe is destroyed? :laugh2:

    So God (whomever that is) can still tell time after spacetime no longer exists. I mean, he doesn't want to be late for dinner! :laugh2:
