Black Hole Swallowing a Star

Traditional gamma ray bursts involve a deluge of high-energy photons bursting through the air.

Through the air? Really? Whatever happened to science reporting?

Well, eventually (for a surface-based human observer) they do.

Yeh, I thought that was what they meant.
What would happen to any planets in the same Galaxy, if we can detect the Gamma Rays here on earth, from a distance of four billion light years?

I was talking about a stationary observer close to the event horizon. Someone being "sucked in" to the black hole would quickly accelerate to within a tiny percentage of c, so their passage to the event horizon would be an incredibly short one - far too short to observe anything!

I was talking all along about someone who was falling in.

Now, on that short trip, how long would it seem to the falling person? Wild guesses accepted.

This short.

Thinking about this again, nothing could fall directly into a black hole, since there would (almost) undoubtedly be an accretion disk around it. You would have to spiral into the BH (thus greatly increasing the "falling" time) in the same direction as the disk, or be pulverised by countless impacts with particles travelling at near lightspeed. And trying to slip in through the bottom ( ) or top wouldn't work, because like in most galaxies, there would probably be a central "bulge" just outside the EH (formed of particles that have been knocked out of the disk by collisions) which would do the same job as the accretion disk, but in a fraction of the time.

I think so anyway.

If you went down the "pole" into the BH, the accretion disk wouldn't be an issue, would it?

I don't think it would, because the gravity effect of the black hole would pull you straight in, if you weren't orbiting it at a phenomenal rate, as in the disk.
I don't think you would get a bulge, like a galaxy, because the gravity would be far too high. And the accretion disk would be so dense as to mop up any particles that were not in it's plane. ( I think ).
A galaxy is so thinly populated by stars, that the stars in the bulge can easily miss each other, and pass right through the disk with only a tiny chance of a collision. ( I think )

Interesting. I can see why Albert rejected this shit out of hand.
