4. Life on Antarctica station, glaciers and climate - Helene Hoffmann
Description
How is life going on an Antarctic station? how physicists study glaciers and extract information about ancient climate? I'm speaking with Helene Hoffmann, she is a physicist from Germany, she studies glaciers and spent more than a year on a German Antarctic station.

I'm speaking with Josh Eby, who is a physicist from Israel, about dark matter. Why do we know it is there? What can it be and what can't? How we are trying to find it.
00:50 How much of dark matter is out there?
1:25 Josh’s journey to the dark matter science?
6:10 Why do we know that there...

Can you imagine how the matter behaved right after the Big Bang?
Consider two atomic nuclei flying toward each other with almost speed of light. What happens if they collide? We create a tiny unstable droplet of the primordial matter.
This matter has nothing in common with the ordinary matter...
