"The Most Dangerous Stuff in the Universe": strangelets from neutron stars


“The Most Dangerous Stuff in the Universe – Strange Stars Explained” by Zurzgesagt for his “In a Nutshell” series.


The stuff is called “strangelets”, variations of elementary sub-particles that may form inside neutron stars. When neutron stars collide, these "strange quarks" might be released into the wild open space.

If a strangelet hit a planet, it might “infect” the planet which turns into grey goo, very much the way prion infections in the brain work. The whole Earth gets mad cow disease.
The Sun goes cold, too, if hit.

But it hasn’t happened in four billion years.
