Absolute zero is the theoretical temperature where molecules and atoms stop moving. They do not vibrate, jiggle or anything at absolute zero. In Celsius, absolute zero is -273 ° C. In Fahrenheit, absolute zero is -459°F (or 0°R). It doesn’t get colder than that!

  1. No, particles (with mass) can’t reach the speed of light, and there’s no maximum temperature that limits the amount of energy a particle can have that we know of.

  2. Bethany Carter says:

    If the coldest possible temperature is when the molecules stop moving, then wouldn’t the hottest temperature be when the molecules are moving at the the speed of light? Is there an equation to tell how hot that would be?
