Scientists have observed the most energetic flare ever seen emanating from a supermassive black hole. The researchers said ...

We measure the “warmness” of the dark matter, i.e. the comoving root-mean-square thermal velocity v hrms (1) , with nearly 3000 spiral galaxy rotation curves in the ...

Gravity and quantum physics interact at the event horizons of black holes, though physicists don’t understand all the details. A new theoretical study has proposed that very small black holes, dubbed ...

Does dark matter follow the same laws as ordinary matter? The mystery of this invisible and hypothetical component of our universe—which neither emits nor reflects light—remains unsolved. A team ...
