Fun facts


The smallest unit of measurement in the universe is the Planck length.

If you want to find the very smallest things around, you'd need to track down something that's the size of the Planck length. At a mere 1.6 x 10-35 meter across, which is the equivalent of around a millionth of a billionth of a billionth of a billionth of a centimeter—or a decimal point followed by 34 zeroes and a one)—it's the smallest possible size of anything in the known universe.

Under the laws of quantum physics, this would be the size of quantum foam, or the tiny wormholes that give space a foam-like structure. If this is beyond you, don't worry: You'd probably need a very advanced degree to fully understand that concept.
