Neutron Stars Just Keep Getting Weirder
Neutron stars are some of the strangest things in the universe, but are they the source of the mysterious Fast Radio Bursts? Or is it aliens? Spoilers: probably not aliens.

Strong Nuclear Force
In this video Paul Andersen explains how the strong nuclear force holds the nucleus together in spite of repulsive electrostatic charges acting on the nucleons. Mesons exchanged between nucleons keep the nucleus intact and gluons...

How Do You Weigh Things in Space?
Astronauts need to know their mass while in orbit, but a normal scale would be free-falling around the Earth with them. So how do they measure their mass without gravity?

Is There Gravity in Space
In a word, "yes" - space is packed with gravity. Hank explains how Isaac Newton described how gravity works, and why even though it seems that things are floating in space, they're still effected by gravity. Every object in the universe...
