Are Black Holes affect by Gravity?

[RomanClock]

http://en.wikipedia.org/wiki/Gravitational_time_dilation

and it has since been confirmed by tests of general relativity.

So, the closer we live to a black hole, the longer someones life span could potentially be?

Then, in theory, as someone gets closer to a black hole it would take longer since time is slowing down?

[NewtonClock]

There is also the idea of how every object in the universe is moving away from the central point (the location of the "Big Bang"). Hence why most celestial bodies give off red light when viewed through a spectrometer (I think that's what they call that little refraction device). Blacks holes probably are affected by that as well.

[RomanClock]

Since the gravitational force of black holes are so powerful, how do we know that the stars in the sky are really in that location? Couldn't black holes bend the light in a way that makes stars appear in different location or strength and we couldn't know since black holes are virtually undetectable?

Also, what if the universe is like a sphere? and traveling in one direction will actually eventually lead to that same point?

Then we'd be on a glome. I already explained in your mind-in-higher-dimension thread why that's highly improbable, but since most people already believe that time is the fourth spatial dimension, fuck it. Let's discuss the possibilities. If we're on a glome, and if you travel back in time long enough you go to the opposite point of the universe and travel forward in time from the beginning of the universe in that location.

No, time has nothing to do with what I suggested. If you start on the surface of the earth and travel north, south, east, or west, you will eventually end up where you started.

Sirius A has a black hole (Sirius B) orbiting it, so yes.

time is the fourth spatial dimension

lol

First temporal dimension.

[Marlin Clock]

Damn it, there's no fourth spacial dimension.

As with the surface of a glome to us three dimensional folks. Loki's got it.

Edit:

A lot of debaters in here would benefit from application of the time dilation equation.

Black Hole + Black Hole = ???

[Blackhole]

We know that they have extremely powerful gravity fields, but do they actually move in space? Once it appears, is it a point of gravity/extremely dense sphere of matter that stays at that exact location or can/does it orbit around other objects?
EX: a black hole that is orbiting around another stronger black hole

I  have no clue.

[KronosClock]

I  have no clue.

Well, maybe if you had read the OTHER 3 PAGES, you might have a clue.

I guess my being the "Blackhole Clock" and not knowing anything on the subject was as ironically funny as it should be....

A lot of people don't understand that the very term "spacetime" was created to refer to the three spatial dimensions and one temporal one without having to say something long and disambiguating like that sentence right there every time you referred to our dimensions. It is in fact a device to AVOID the confusion of the temporal dimensions with the spatial ones.

[Exclamation Mark]

"In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy, as calculated by the equation Ug = − Gm1m2 / r. It is commonly described as the speed needed to "break free" from a gravitational field."

That means if you are in the black hole's gravitational field, which you would have to be to use it's gravitational field as a slingshot, you have to be traveling faster than the speed of light to escape it's gravitational field. That's the definition of a black hole.

"A black hole is a region of space in which the gravitational field is so powerful that nothing can escape after having fallen past the event horizon. The name comes from the fact that even electromagnetic radiation (e.g. light) is unable to escape, rendering the interior invisible."

Assuming the gravitational field if the black hole ends after the event horizon, or at least becomes too thin to use effectively as a slingshot. Think about the amount of non-lethal gravitational space you need for such a maneuver.

No. That only counts in the black hole's event horizon, a black holes gravity would still affect you outside the event horizon, but you can actually escape it as the escape velocity is less than the speed of light. So you could use a black hole as a sling shot, as long as you never entered the event horizon.


Hold on, that's right is it not?

i heared theres a black hole at uranus.

hahaha man, 2008 me is hilarious.

hahaha man, 2008 me is hilarious.

Don't you find it wierd to be talking about your past self?

EDIT: Wait, I thought about it, and I'm I'm a edgy teen.
