SomethiNg Doesn't add up

Exhibit A:
The Coma Cluster

"The average density in the COMA system would have to be at least 400 times greater than that of visible matter."

Fritz Zwicky

Henceforth, it shall be known as Dark... Matter.

Astronomers are spherical bastards.

No matter how you look at them, they are just bastards.

Dark Matter

  • We can't see it
  • We can't touch it
  • We don't know what it is

We use it to explain 85% of the mass in the Universe

Einstein to the rescue

The smoking gun

The bulleT cluster

Dark Matter

  • So actually we can see and study it
  • It works beautifully
  • Some ideas of what it might be
  • Or... this is all nonsense and Einstein was wrong ¯\_(ツ)_/¯
