Why Do Black Holes Have Such Strong Gravity?

I say we turn the sun into a black hole in the name of science!

cmon its his own book ofcourse you'd advertise.Its nothing imoral.He wants to make a couple bucks, annd free advertising please!Anybody would do it unless your stupid.

nice well now i know

There are different "forces" in the Creation. The magnetic force is not the same as gravitational acceleration. Gravity is actually not a 'force'. F=(M)x(A), force is defined as a mass x acceleration. This equation is also written as F=(M)x(g), where (g)is the gravitational acceleration on Earth = 9.8 meters per sec. per sec. or meters per sec. squared. gravity is a weak attraction; Electrical 'force' within the atom is much greater

Nice clip, I loved the explanation, simple but clear.

Come again?I'm a student in electrical engineering,which means I don't have any expertise on astronomy but I *do* know quite a lot about electrostatic and magnetostatic fields(sorry if these are not the right words,english is not my first language so I try to translate the terms as best I can).In the case of black holes I thought it was only their gravity that was noteworthy,but if electromagnetic fields have anything to do with their behaviour that would be very interesting.So...care to xplain?

"??? your kidding right? i would tell you to read up on physics if i thought you were not kidding, but to even post anything about this i would expect you to have a little nawledge about the subject."

OMG learn to S P E L L !
You can´t pull off putting someone else down if you make yourself look like an imbecile while doing it...
"nawledge" lol!

Thanks again Phil, love your explanation. Now to make out to my friends that I knew that all along!

I agree, it is getting ridiculous

I hate assholes who use this site for advertising, buggger off!!!

shithead!

??? your kidding right? i would tell you to read up on physics if i thought you were not kidding, but to even post anything about this i would expect you to have a little nawledge about the subject.

Yes, yes it is.

Is it true that space is expanding?

That's actually a really good question and explanation. Never thought about it before.

paper... OF science

a magnetic feald has gravit that why it sticks to it

That would be a black hole, wouldn't it?

What do magnets have to do with it?

Well the "bas astronomy" title is right on the money. At least he plugged his new book.

This is why I love you, Phil. Brilliant explanation.

It is the same gravity, it's just that a black hole is more dense.

If in a binary star system, one of them turned into a black hole, the other would be sucked in. If they turned into black holes at the exact same moment, well I don't know probably a Binary black hole system or something.

Try a video reply to this video

Black holes = Ewoks
Stuff that gets sucked in = storm troopers

So you're saying that the event horizon of a black hole would be closer to the center of mass than the surface of the star it used to be?
