Scientists over at Boulder, Colorado, have developed the what looks like the most advanced and accurate clock. Plus, it will keep precise time for five billion years (5,000,000,000 yrs). That’s amazing engineering.

Unintended side effect:

But this new clock has run into a big problem: This thing we call time doesn’t tick at the same rate everywhere in the universe. Or even on our planet.

If you took two of these clocks and put one higher even a few inches, the two clocks would start reading time differently. Not much, but that difference would build up.

Why? Gravity. In fact, one of the proposed uses of this kind of device is to measure gravity to help get a better picture of the make-up of the planet.

Science is cool.
