Black Hole Stars

Imagine a star that is millions of times bigger than our sun, big enough to fill our entire solar system. The star is so large that its gravity and internal pressure is unimaginable, and eventually the very center becomes a black hole. This black hole is sucking the star's mass into itself rapidly from the center, but the star is so big that the surface is barely affected. This kind of star would only be possible in the early days of the universe, when more mass was packed into a smaller space. A black hole star is, at this point, theoretical. But their existence billions of years ago could explain some phenomena that have confounded astronomers and physicists. This video is only ten minutes; the rest is a promotion.
