The Vast Majority Of Matter in the Universe is Invisible

The Vast Majority Of The Matter In The Universe Is Invisible To Us"There’s a lot of stuff in the universe, and all that stuff is helping the universe expand. The problem is, we’ve accounted for all the matter we can see (stars, galaxies, etc.). Yet somehow, all of it doesn’t add up to the amount we need for the expansion we’ve observed. What gives? Scientists have cleverly named this missing matter “dark matter” since we can’t see it, but are pretty sure it has to be there. It should account for about 85% of all the matter in the universe. That’s a lot of matter that’s missing."https://www.highpointscientific.com/astronomy-hub/post/astronomy-101/10-astronomy-facts-every-stargazer-should-know
