Normal matter made of atoms takes up approx. 15% of our universe.
The other 85% is missing. But because of this absence, scientists have theorised a new type of matter: dark matter.
We know something mysterious exists like this because a strange force is making the universe expand and changing the rotation of galaxies.
All of this might seem simple, but no. We don’t actually know what dark matter is, and studies have shown it can’t touch anything.
Above is a map of the universe, created using heat-detecting cameras. Maybe this could help us find the temperature of dark matter?
Am I able to post a comment on Mute Monday? If so I'd like to express my thanks to the author of the post. By looking at all the interesting and diverse blog posts I'm learning so much from the comfort of my sofa.
