The reason we call dark matter dark isn't that it's some shadowy material. It's because dark matter doesn't interact with light. The difference is subtle, but important. Regular matter can be dark because it absorbs light. ...

It takes a long time for supermassive black holes, like the one at the center of our Milky Way galaxy, to form. Typically, the birth of a black hole requires a giant star with the mass of at least 50 of our suns to burn out—a ...

In a new study, scientists from Canada have proposed a solution to the final parsec problem of supermassive black hole (SMBH) mergers using self-interacting dark matter.
The dense peaks in the wavelength distribution graph observed in a Lyman-Alpha forest indeed resemble many small trees. Each of those peaks represents a sudden drop in "light" at a specific and narrow wavelength, effectively ...
