The birth of a black hole is a dramatic event rooted in the life cycle of a massive star. When such a star depletes its nuclear fuel, it no longer has the energy to counteract the force of its own gravity. The core of the star collapses under this immense gravitational force. For stars with a significantly large mass, this collapse leads to a spectacular explosion known as a supernova. In the aftermath of this explosion, if the remaining mass of the star’s core is sufficiently dense, it collapses further into a point of infinite density and zero volume, known as a singularity, forming a stellar black hole.
JWST???s first triple-image supernova could save the Universe
One potential solution could lie in directly measuring larger numbers of objects whose intrinsic properties are known — so-called “standard candles” like type Ia…
