Astrophysicists Stumped as NGC 1052-DF2 Galaxy Contains no Dark Matter

Dark matter continues to mystify astrophysicists as a new galaxy, 65 million light-years away, filled with stars, but with no “apparent” dark matter has been discovered. Making up more than 85% of the matter in...

Soon Time and the Universe May Come to an End

A new theory claims that the universe isn’t expanding at accelerating rates, suggesting that it is “time” that’s increasingly slowing down and could one day come to a halt. Astrophysicists think the observed recession of...
