What would happen to a star if it took a direct hit from a gamma ray burst? For example if a gamma ray burst from a supermassive black hole at the center of a galaxy hit a star, would the star survive? If so, how would the grb effect the star? If not, would the star explode...

This is a cool idea. Also, wouldn't light that is close but not beyond the event horizon experience strong lensing as well? There are cases when astronomers see duplicate images of galaxies due to strong gravitational lensing so it seems like a black hole would create a significant...

You're referring to theoretical models? What if the EH is just a buzzsaw that shreds matter and then bats it back out into space? I don't see why it anything has to pass the EH.

Is anything known about the nature of things beyond the event horizon? Specifically how light is not fast enough to escape (once it goes beyond the event horizon), does this mean matter is falling into a black hole faster than light? If so, is this an exception to the cosmic speed limit?

If the escape velocity is greater than the speed of light then how does the material from quasars escape? I know they say that a black hole takes in too much matter than it can handle and expels it but how does that light escape?

It seems like black holes could just as easily be expelling the matter they rip up. Couldn't a black hole just be something that rips matter apart atom by atom and then blasts it back into space? In this case there wouldn't be a need for a singularity. Quasars are one example of how they...

Thank you everyone. Do we know enough about the physics of a black hole to accurately model it on a computer? If so, I would think the software would allow a user to rotate around it from all angles to see its full shape.

Is it shaped like a tornado, or a sphere, or is it flat like a disk? If there was a way to view a black hole, dimming the brightness around it to get a clear look, what would be its full shape if you could view all around the outside of it from every possible angle?

I was curious if a wandering black hole about the size of the core of the sun could sweep through it and void out the core and ignite it into a supernova.

Thanks! So it would spiral inward but then what? Would it just cool and dissolve?

Would a star that is too small to go supernova (Sol or Alpha Centauri) still go supernova if its core somehow instantly vanished? Wouldn't gravity collapse it and wouldn't that pressure be the same as the pressure that makes larger stars go supernova?
