Parasitic black holes may explain cosmic flashes
Gamma-ray bursts are very powerful and very bright events. They release in a momentary flash of gamma-rays and X-rays more energy than the sun does in its entire lifetime.
(Luckily, their are no sources of these bursts in our galaxy, otherwise we would be toast).
Gamma-ray bursts have been thought to occur because of massive dying stars collapsing into a black hole and bursting with radiation in the process. However, the bursts also have an afterglow of X-ray radiation that this theory can’t explain.
A new theory can. According to the new theory, a gamma-ray burst is the result of a black hole burrowing into a star and eating it from the inside like a gigantic light-devouring parasite.
It remains to be seen if the new theory can also account for other aspects of gamma-ray bursts. Did anyone say paradigm shift?
