A new study proposes that the upper mass limit for black holes could be a million times larger than we…
There's no way to Measure the Speed of Light in a Single Direction
A new study shows that not even cosmology can verify Einstein's assumption about the speed of light.
New Data Supports the Modified Gravity Explanation for Dark Matter, Much to the Surprise of the Researchers
A team of astronomers set out to disprove modified gravity, and ended up confirming it instead.
