Scientists find evidence for theorized gargantuan star explosions

A supernova – the explosive death of a star – is always violent, blasting material into space while typically leaving behind a compact stellar remnant like a neutron star or black hole. But some ​supernovas involving the largest stars in the cosmos may be so immensely powerful they leave absolutely nothing behind. Scientists since the 1960s have theorized the existence ‌of these ultra-powerful supernovas, and have now come up with evidence for them – albeit indirect – in research involving black holes and ripples in spacetime called gravitational waves. Such supernovas are predicted to occur in the most enormous stars – those with a mass around 140 to 260 times greater than the sun,...
