What is the coldest substance known to man? 0:14 - 0:16 They're in physics labs: 0:16 - 0:20 clouds of gases held just fractions of a degree above absolute zero. Lina Marieth Hoyos explains how temperatures this low give scientists a window into the inner workings of matter, and allow engineers to build incredibly sensitive instruments that tell us more about the universe. The protoplanetary Boomerang Nebula, located 5,000 light-years from Earth, holds the record for coldest known object in the Universe. That's what happens in a device called a magneto-optical trap. Atoms are injected into a vacuum chamber, and a magnetic field draws them towards the center. Yet, that still isn't the coldest temperature we have ever measured. What in the world is topological quantum matter? A laser beam aimed at the middle of the chamber is tuned to just the right frequency that an atom moving towards it will absorb a photon of the laser beam and slow down.

However, the coldest natural spot in the Universe currently is the Boomerang nebula, which resides 5,000 light-years away from us. Create and share a new lesson based on this one. Under most circumstances, the energy in a laser beam heats things up. The slow down effect comes from the transfer of momentum between the atom and the photon. Since then, laser cooling has been improved to reach even lower temperatures. They're in physics labs: When we're talking about temperature, what we're really talking about is motion.

Summaries. But used in a very precise way, the beam's momentum can stall moving atoms, cooling them down. Lina Marieth Hoyos explains how temperatures this low give scientists a window into the inner workings of matter, and allow engineers to build incredibly sensitive instruments that tell us more about the universe. The atoms that make up solids, liquids, and gases are moving all the time. At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000 F! It looks like we don't have any Plot Summaries for this title yet. So as researchers continue in their quest to understand the laws of physics and unravel the mysteries of the universe, they'll do so with the help of the very coldest atoms in it. Examples include Dippin' Dots or other ice cream cereal fruits or cocktails prepared by adding liquid nitrogen at the point of sale and eating it shortly thereafter. 0:13 - 0:14 or buried in a glacier. A chunk of copper became the coldest cubic meter (35.3 cubic feet) on Earth when researchers chilled it to 6 millikelvins, or six-thousandths of a degree above absolute zero (0 Kelvin). - Lina Marieth Hoyos.
