A black star does not have an event horizon, A neutron star does not have event horizon either.. Black holes are NOT dead stars., no matter how many people insist that they are just dead stars.
-
spot a say: This is not possible, although the black hole is the remnant of a huge star which went supernova or hypernova
-
Larry Phischman say: No. Their mass is too high for any kind of star. There are other hypothetical objects that could explain the observations, but they are not stars.
-
Mike G say: Then tell us what a black star is. Don't forget the physics.
-
Nyx say: Not based on the evidence found so far.
-
Kate say: no. just no. you clearly have no idea how light works.
-
quantumclaustrophobe say: Well, no... the reason is the Xray emissions coming from them. That's from material getting so energetic in the accretion disk - just before it disappears in the Event Horizon - that it's emitting x-rays... that can only happen over a very small, very *dense* object - and, a star, at hundreds of thousands to millions of miles across - couldn't replicate that.
