Hi, I'm Jared, with more science news you can use.

2
00:00:04,000 --> 00:00:09,000
What is the coolest gas in the universe?

3
00:00:09,000 --> 00:00:10,000
I have no idea.

4
00:00:10,000 --> 00:00:16,000
Scientists have been able to cool down gases to temperatures of about a hundred billionths of a degree.

5
00:00:16,000 --> 00:00:17,000
How do they do that?

6
00:00:17,000 --> 00:00:23,000
Atoms move faster than hotter gases, so to cool a gas, you have to make the atoms move slower.

7
00:00:23,000 --> 00:00:26,000
To do this, scientists shoot laser beams off the atoms.

8
00:00:26,000 --> 00:00:28,000
Interesting, but why?

9
00:00:28,000 --> 00:00:32,000
What they did was produce a new state of matter called Bose-Einstein.

10
00:00:32,000 --> 00:00:37,000
Is this new matter different from the three states of matter that we now know about?

11
00:00:37,000 --> 00:00:39,000
Gas, liquids, and solids?

12
00:00:39,000 --> 00:00:45,000
Yes, and the technology that created this new matter has improved clocks that use atoms to tell time.

13
00:00:45,000 --> 00:00:50,000
In the future, this technology can help us navigate long distances in deep space.

14
00:00:50,000 --> 00:00:53,000
