1 day ago · In astronomy, dark matter is a hypothetical form of matter that appears not to interact with light or the electromagnetic field. Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be seen.

Fifty years ago, physicist Stephen Hawking offered one idea for what dark matter might be: a population of black holes, which might have formed very soon after the Big Bang.
4 days ago · Francesca - The first hints at dark matter were really discovered by Zwicky in the 1930s, and he was looking at galaxy clusters. So these are massive structures. And at that time when Zwicky was working, most physicists assumed that the matter we can actually detect directly with our telescopes was all that was.

2 days ago · Both dark matter and dark energy are invisible, but they are not the same. Dark energy is sometimes called anti-gravity or gravity’s evil twin, while dark matter is a gravitational force holding mass together and is sometimes known as cosmic cement or gravitational glue. “The nature of dark energy is mysterious,” Blazek says.
