Minute Physics: What is Dark Matter?

Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

In this episode, we discuss Dark Matter, an exotic type of matter we know very little about, despite the fact that it makes up around 80% of all matter in the universe!

So basically what you are saying is that when push comes to shove ,you don't really understand anything .Must suck to be a physicist in 21st century ad.

@moro1891 You seem to be confused between dark matter and dark energy. Dark matter only interacts through gravity, pulling GALAXIES together, not the universe itself. Although it gravity exerts a pull on the universe, this is vastly overwhelmed by dark energy, something that we pretty much have no idea about.

[john96797]

In astronomy and cosmology, dark matter is a currently-undetermined type of matter hypothesized to account for a large part of the mass of the universe, but which neither emits nor scatters light or other electromagnetic radiation, and so cannot be directly seen with telescopes. Dark matter is estimated to constitute 83% of the matter in the universe and 23% of the mass-energy

What is this related to charlie bit me ?

@moro1891 actually, dark matter is an abnormal type of matter that keeps things in place, or just lags them. He has the right idea. I've actually never heard of your dark matter being a vaccum theory though.
