The coldest natural temperature in the known universe is the Boomerang Nebula. Even that temperature is not at 0oK.
Why It Matters
- The world record for the coldest temperature in a lab is 0.0000000001oK.
- The coldest known temperatures in the universe are in laboratories on Earth.
- The thermodynamic temperature scale measures the kinetic energy in a material.
- The Heisenberg Uncertainty Principle states that is impossible to know the momentum and exact position of a particle at the same time.
- It’s impossible for a substance to reach true absolute zero.
- Super cold substances have unusual properties that are very useful.
NASA plans to create the coldest place in existence on the International Space Station in 2016

- What is heat?
- What happens if the molecules in a substance no longer move at all?
- What happened when Lord Kelvin drained all of the kinetic energy from many different substances? What did he call this?
- What does it mean that some substances become superconductive at temperatures below 30oK?
- Why won’t we ever get a substance down to absolute zero in the lab?
