Scientists to build clock that lasts forever

Theoretical scientists have come up with a way to build a four-dimensional space-time crystal clock.

The idea behind such a device is that it will literally last indefinitely, outlasting even the heat death of the universe. Scientists have long speculated over the concept of a space-time clock based on a four-dimensional crystal that has periodic structure in both time as well as in space, but the idea of creating one has been refined for the most part to the realm of science fiction. Now however an international science team believes they may have come up with a way to actually build one based on an electric-field ion trap.

"The electric field of the ion trap holds charged particles in place and Coulomb repulsion causes them to spontaneously form a spatial ring crystal," said scientist Xiang Zhang.

"Imagine a clock that will keep perfect time forever, even after the heat-death of the universe."

Ouch, that makes my brain hurt

If this becomes a reality, I guess that puts an end to built-in obsolescence.

I thought I was an intelligent educated guy. Until I read that article. I was with them all the way up to the mention of four dimensions.

Interesting. But who's going to give a damn what time it is after the heat-death of the Universe

We may go to that time and would still be able to tell the time even if nothing is around. Also we would know that we are in the future

The OP article points out some of the "practical" values of this new possibility. Only time will tell what benefits Mankind may gain. It's a potential tool for studying and understanding our universe. One example from the article: [indent=1]With such a 4D crystal, scientists would have a new and more effective means by which to study how complex physical properties and behaviors emerge from the collective interactions of large numbers of individual particles, the so-called many-body problem of physics.[/indent]

I bet it will still get confused when the clocks go back in October...

Uh... will it fit in my watch?
