E = mc 2 may be the most quotidian equation in physics. Everyone’s heard of it and it’s been proven time and again. Did you convert mass into energy? Go tell it to the stars, whose light is generated ...

Black holes can’t be formed from pure light. Quantum physics would curb their creation under any foreseeable conditions, a new study suggests. Typically, matter is responsible for black holes. They’re ...
