Black holes could be dark stars with 'Planck hearts'

They may not be black or holes.

Black holes, those gravitational monsters so named because no light can escape their clutches, are by far the most mysterious objects in the universe.

But a new theory proposes that black holes may not be black at all. According to a new study, these black holes may instead be dark stars home to exotic physics at their core. This mysterious new physics may cause these dark stars to emit a strange type of radiation; that radiation could in turn explain all the mysterious dark matter in the universe, which tugs on everything but emits no light.

Dark stars
Thanks to Einstein’s theory of general relativity, which describes how matter warps space-time, we know that some massive stars can collapse in on themselves to such a degree that they just keep collapsing, shrinking down into an infinitely tiny point — a singularity.

Once the singularity forms, it surrounds itself with an event horizon. This is the ultimate one-way street in the universe. At the event horizon, the gravitational pull of the black hole is so strong that in order to leave, you’d have to travel faster than light does. Since traveling faster than the speed of light is utterly forbidden, anything that crosses the threshold is doomed forever.

1. Wish they'd said "utterly impossible", not "utterly forbidden".

"Forbidden" implies an intentional stance, which is required neither by theory nor empirical evidence.

2. It did seem peculiar. Glad to see your comment. Thank you.
