In my last question, I wanted to know if we were in a path of a black hole, what would happen 1st, ie: I know already that the Earth will be sucked in and crushed. but before we get to that, will it be over instantly, or will people suffer from things happening first whe earth hits the black holes gravity field... ie: people being pulled up to the sky, etc?

If Earth were falling into a black hole, it will break up and form a disk around it, and be sucked in as a fine stream of utterly pulverized dust. If the black hole were big enough (like one of those supermassive ones at the center of galaxies), it might just suck earth up in one gulp, no accretion disks or pulverizaiton. The chance of Earth coming anywhere near one of those is almost nothing though.

sewrrob, the sun will never go supernova, and never be a black hole, it is too small to do either. The ultimate fate of the sun is to become a cool, white dwarf, dissipating heat, and this is possibly around 5 billion years off. Anyway, a black hole was once a star. New mass is not created by becoming a black hole, so it will have no more mass than the star did, it will merely be more dense. Its total gravitational influence will be no more than that of the former star. Many galaxies, perhaps all of them, most likely including our own Galaxy, have one or more black holes at the centre. Nothing as we no has thus far fallen into the centre of our Galaxy.

Black holes are objects where great mass is concentrated into an infinitessimal volume. But they do not necesarily "suck in" all around them. The gavitational attraction between two bodies is proportional to the two masses multiplied together, divided by the square of the distance between them. Note that only the masses and the distance are involved. The radius or volume of either object is immaterial. If all the mass of the Sun were compressed into a single point, the Earth would continue to orbit exactly as before since masses and centre-to-centre distances would be unchanged.
Until you start to get near the Event Horizon, the effect of a massive black hole far away would be indistinguishable from that of a less massive object much closer. It would start perturbing our orbit long before "spaghettification" occurred. We would thus fry or freeze long before that.

Yes, at certain distance, items not tied down will be pulled up to sky.
The atmosphere will go and it is so windy that small items will be blow up with the atmosphere.
then as the earth get closer, the closer items, include humans, to the black hole will get pull towards it.
Gravitational pull is magnitude of distances. So, the Earth will get torn aport as the the substance closer to the black hole will accerlerate faster than the items far away from hole.
Everything will be torn apart before it gets into the hole.

Scientists aren't 100% sure what goes on inside a black hole. They say it's gravitational pull is so strong that nothing can escape it. So if our planet was sucked into one it'd probably rip the planet apart instantly. It's not a slow process.

yes there is a black hole near earth but nasa has kept it quiet as not to panic the little peaple
your mum and dad will panic and not pay the rent if they thought there was a black hole coming to kill us all
so please do tell them !!
then you will still have a home to live in

ye I've been with a few black holes in my life!!! lol . your hair stands on end and your eyes will pop your body will be compacted into a nice flexible friend card size....hee hee

Not in our solar system and we have not seen them outside of
our solar system which means they are quite a fair distence away.

It's never, ever going to happen but they are interesting. I found these links useful
