The Black Hole..
 

I was thinkin about the illedged black hole which is situated right in the middle of the milky way (not the choc bar). Its the sagitarious (a) star that is supposed to be the center if i have got my facts straight. This hole is said to be getting bigger over time sucking in stars from the milky way one by one, till in a few billion years they reckon that our whole solar system will be sucked into this hole and all that will be left is gravity.

Q. where will the 'gravity' be pulling will it simply be pulling through the hole or what?

Thought. for every action there has to be an adverse action.

Q. so do you think at the other side of yhe universe there is a similar hole spewing out solar systems creating an endless string of creation/destruction?

:eek: :confused: :eek:

1. The gravity will be pulling towards the hole, yes.
2. hard question.

y cant we just live our lives...we wont be around for it anywayz:up:

If everything that goes into the hole get destroyed, and the hole spews out x-rays and other mad gasses, what the f... is on the other side of it? If something has a hole, that hole generally leads somewhere unless its blocked, but if its blocked there would be either no suction or very little, or its creating a vacume. If it is creating a vacume will it explode and cause another big bang theory? Or is there life beyond the black hole?:confused:

or maybe the idea of a black hole is to cover up the mystery that the universe is not evenly dispersed such as an explosion would produce.
black holes have effect on light eh? tis a wonder they are taught as emperical scientific facts but still are acknowledged as theory at best.

i still think it's president bush's fault, damn bastard who decided to drill holes in space. that's my theory.

well actually a bigger black hole is a weaker one becuase the gravity would be less dence, so in theroy, eventualy once a black hole gets big enough, the quantum sinqularity will implode, thus making antimatter, and everyone knows that antimatter and matter dont really mix all that well :rolleyes:

What would happen to me if I fell into a black hole?
----------------------------------------------------
Let's suppose that you get into your spaceship and point it straight towards the million-solar-mass black hole in the center of our galaxy. (Actually, there's some debate about whether our galaxy contains a central black hole, but let's assume it does for the moment.) Starting from a long way away from the black hole, you just turn off your rockets and coast in. What happens?

At first, you don't feel any gravitational forces at all. Since you're in free fall, every part of your body and your spaceship is being pulled in the same way, and so you feel weightless. (This is exactly the same thing that happens to astronauts in Earth orbit: even though both astronauts and space shuttle are being pulled by the Earth's gravity, they don't feel any gravitational force because everything is being pulled in exactly the same way.) As you get closer and closer to the center of the hole, though, you start to feel "tidal" gravitational forces. Imagine that your feet are closer to the center than your head. The gravitational pull gets stronger as you get closer to the center of the hole, so your feet feel a stronger pull than your head does. As a result you feel "stretched." (This force is called a tidal force because it is exactly like the forces that cause tides on earth.) These tidal forces get more and more intense as you get closer to the center, and eventually they will rip you apart.

For a very large black hole like the one you're falling into, the tidal forces are not really noticeable until you get within about 600,000 kilometers of the center. Note that this is after you've crossed the horizon. If you were falling into a smaller black hole, say one that weighed as much as the Sun, tidal forces would start to make you quite uncomfortable when you were about 6000 kilometers away from the center, and you would have been torn apart by them long before you crossed the horizon. (That's why we decided to let you jump into a big black hole instead of a small one: we wanted you to survive at least until you got inside.)

What do you see as you are falling in? Surprisingly, you don't necessarily see anything particularly interesting. Images of faraway objects may be distorted in strange ways, since the black hole's gravity bends light, but that's about it. In particular, nothing special happens at the moment when you cross the horizon. Even after you've crossed the horizon, you can still see things on the outside: after all, the light from the things on the outside can still reach you. No one on the outside can see you, of course, since the light from you can't escape past the horizon.

How long does the whole process take? Well, of course, it depends on how far away you start from. Let's say you start at rest from a point whose distance from the singularity is ten times the black hole's radius. Then for a million-solar-mass black hole, it takes you about 8 minutes to reach the horizon. Once you've gotten that far, it takes you only another seven seconds to hit the singularity. By the way, this time scales with the size of the black hole, so if you'd jumped into a smaller black hole, your time of death would be that much sooner.

Once you've crossed the horizon, in your remaining seven seconds, you might panic and start to fire your rockets in a desperate attempt to avoid the singularity. Unfortunately, it's hopeless, since the singularity lies in your future, and there's no way to avoid your future. In fact, the harder you fire your rockets, the sooner you hit the singularity. It's best just to sit back and enjoy the ride.

Why do we care? I doubt the human race will exist in a few billion years.

Kljs you either are very warped or well read
i really liked that anote 'What would happen if i fell
into a black hole' apart from hitting singularity it
sounds like a cool trip. (visuals would definatly be
better than my presets). :)

Asimov book called "The God's themselves" deals with this

I like to read on extraordinary things.......

Just for knowledge only......

I use this to impress my friends....

Kinda cheap way to impress,but it gets the job done!!

I think blackholes are the natural "trash collectors" in space... preventing too much debris from collecting over billions of years....

That is not strictly true, time dilation effects would mean that you never reach the the centre of a black hole, depending where you are of course

I've got an idea....Im gonna have myself cryogenically frozen for a billion years, then come back in time to this exact moment and let you know what happened...

ok..im back from the year 1,000,002,002...and i gotta say it was nothin special

Oh yeh, while i was there i stopped to get the current news, and WA3 had finally been released...:p

Seriously though, Does it really matter what happens in a billion years?? We either wont be here to know about it, or we'll all have evolved into llamas and be piloting space ships all over the universe...

not me I will be going round trading on the intergalactic soul market:D

How about a simpler query:

If a fair portion of people survive on a rice diet, why isn't their excrement colored white?:weird:

I thought the whole "white" hole thing had been put aside. Isn't the thought now that black holes evaporate, through their radiation? (even thought this evaportation takes Billions or more years.)

I vaguely remember a theory from somewhere that said, if you enter a black hole and could somehow survive the journey, you would pop out in another time or dimension. A paralell universe.

I think these scientific discussions are intriguing and very important. If we don`t solve these universial matters here in the Winamp forums who will ?

:D :)

Which brings up the question ; Do you shit what you eat or eat what you shit ?

Along the same line; how can a black cow eat green grass and give white milk ?

:D

we all gonna go cos of global warmin or the death of the sun 1st... but, i agree, there must be sumthin on the other side of the black hole...

the sun wont die out for a few billion years!

Because the black hole on your butt turns it into dark matter. :D

I've read it. It's a great book. There also an interesting movie that was made from the book. It combines information from the book with documentary footage of Hawking himself. You should check it out.

Also, The Elegant Universe by Brian Greene is a book on string theory written for the layman, meaning it doesn't get involved with all the complex mathematical stuff but it still makes your head spin. Highly recommended for anyone interested in modern theoretical physics.

whoa......
 

Smart people....damn so much knowledge in this thread...i feel smarter...welll acually no...ull just made me feel dumber..lol:confused:

Quoted from a physic book.
Event Horizon is the surface of the sphere surrounding a black hole.

Any volunteers?

I was always under the impression that a black hole is infinitly small and infinitly dense.

About the whole what will we be able to do about it, I give you this simple fact: 66 years after conquering the skys with the first aircraft, we put a man on another stellar body(the moon). We have sent probes past the oort cloud, which is located beyond pluto, and we still, on occasion, hear from them. Imagine what we will be able to do in a billion years of scientific discovery. Hell, if computer speed continues to follow the trend of doubling in speed every 18 months, just think how fast the computers will be by then.

Lets see the distance to the moon is about 238,857 miles and the age
of man is about 11,000 (I don't wanna hear from you creationist on
this one) so man is traveling an average of 21.714(27)forever miles
a year. We wont be getting to a black hole anytime soon.

I am fairly sure an exponential equasion dealing with the maximum speed man can travel at would work better for what you are trying to say.

Taken from the same book. :)

Black hole, pfft!:rolleyes:

I thought this was a thread about ex-wives thanks to the thread title:p

Event Horizon is the surface of the sphere surrounding a black hole.

I reckon if your into 'pushing bounderies'
this is definatly the one for you 'total and utter confusion.' then fortunatly your dead. a bit like doing an overdose of salvia divinorum or such, except you dont physically get ripped to atoms doing drugs you just think you do.

Have you seen the movie 'Event Horizon' "f.u.b.a.r."
