A small team of astrophysicists affiliated with several institutions in China has found evidence that suggests if wormholes are real, they might magnify light by 100,000 times. In their paper published in the journal Physical ...
Astronomers have directly measured the mass of a dead star using an effect known as gravitational microlensing, first predicted by Albert Einstein in his General Theory of Relativity, and first observed by two Cambridge astronomers ...

Primordial black holes (PBHs) are fascinating cosmic bodies that have been widely investigated by astrophysicists worldwide. As suggested by their name, these are black holes believed to have appeared in the universe's early ...
If, as astronomers believe, the deaths of large stars leave behind black holes, there should be hundreds of millions of them scattered throughout the Milky Way galaxy. The problem is, isolated black holes are invisible.
