How Do Black Holes Form?
Question: How do black holes form? — Harsh
Answer: I think that my colleagues at NASA have produced a very nice explanation of what black holes are and how they form. In a nutshell, when a massive object has not way to support itself against gravity, it collapses in upon itself. If that object is massive enough, then its gravitational pull can arrest even the propagation of light, making it appear “black” to us.
