If an object that have mass is pulled by gravity, it'd accelerate with time. Would someday the object travels faster than light?
Let's just imagine that the object would never reach the center of the gravitation.
As we know, when we travels near lightspeed, mass increases, but gravity's acceleration to an object is not affected by mass isn't it?

which would be faster?
an object travelling 1000000000000000000m/s
or an object that travels 1m/s, but every seconds the speed increase by 1m/s

but the increased mass won't effect the ability of gravity to accelerate the object

speed of light. If this mass is never reaching the CG then the gravitional field of that object is huge and then its acceleration of gravity will be equally negligible.
If for argument sake we take that this mass reaches lightspeed somehow during this motion then its mass will increases and the Centre of gavity will shift closer to this mass and its acceleration will fall. So under any circumstances it will never cross the light speed.
Do the math and you will figure it out.

The theory around this is very fuzzy. Some say nothing can travel faster than light. But a black hole that has a huge gravitational force should be able to pull an object and accelerate to a speed higher than the speed of light.
This depends upon 2 conditions.
1) the pulled body has enough distance to accelerate to above the speed of light.
2) The gravity will still continue to pull when the body reaches the speed of light and above. We don't completely know the behavior of the gravity.
Note: The teriminal velocity is due the atmosphere. We have to assume there is no atmosphere in the black hole we are testing.

Create your own gravity and you can travel much much faster than the speed of light. If you can manipulate gravity, you can manipulate the space/time continuim. This is the process behind the so-called disk technology, also called UFO's, and is, among other things, one reason why Einsteins Unified Field theory is so intriguing. Remember when you manipulate the space/time continium with gravity our present S/T continuim flows around you and you are not quite in this dimension. That is why the disks can make right angle turns at 4000 mph without the occupants being splattered against the side. They are not completely within this dimension so the laws of inertia do not affect them in the same way.
Now if you stay completely within the 3rd dimensional
world your going to have a hard time going faster than the speed of light, at least that's my guess, there may be a way to do even that.

Time and distance are the key to this question. Any object accelerated long enough by an object of infinite mass (a black hole) can reach the speed of light so the answer to your first question is given enough time and distance, they are equal. As to the addons, any object accelerating for a long enough time will reach the speed of light, which is the limit of normal speeds across normal space.

Dude..your talking about the factors that make up a black hole.
When the mass of a star gets to a point where it is so big that the gravity will not let light escape it forms a black hole.
The gravity on earth lets us move around, just imagine a gravity pull so strong that light can not escape it.
There fore gravity is more powerful then light.
Gravity can suck in light if the mass is big anough to do so.
Every one asks what is on the other side of a black hole, this is my theory.
To become (ourselfs) invisable we must make it so light rays can not escape are body.
All we see when we look at something is relfected rays of light.
So no reflectes light still means that the person is there, but you cant see them.
That's why we cant see anything on the other side of a black hole becuase it becomes invisable.
If you think about it everything is on the other side of black hole we just cant see it.
There is more to this theory than you could believe.
Time travel is possible by this theory!
But if i tell you it then what?

Speed of light is faster.
The graviational acceleration is related to the mass of both objects and the distance squared between them. So at an infinitely far away distance the acceleration and gravity is zero. However, given Newton's law of inertia (objects in motion want to remain in motion and objects at rest want to remain at rest) two objects don't have to be infinitely far away to not exert acceleration on eachother. For instance, two rocks a couple of miles apart in space won't really exert gravitational acceleration on eachother.
Basically, you would never be able to place two objects apart such that they accelerate eachother long enough to achieve the speed of light or faster.

Any object, as it nears the speed of light, has incresed mass. So as this imaginary object affected by gravity approaches the speed of light, it's mass will increase accordingly.

The answer is that Einstein made a mistake when he surmised that an accelerating mass has additional mass added to it in form of energy. This has led to the thought that "black holes" are possible and that it is impossible for a mass to reach the speed of light.
Were you to check out the acceleration of a mass, were it dropped 0.716 miles from the center of our planet, it would become apparent that the mass would exceed the speed of light in one second. In our sun, the distance is 400 miles from its core point.
Should you have an interest in understanding what the background to mass acceleration is, you might check http://360.yahoo.com/noddarc scroll down to "The Problem and Repair of Relativity".

speed of light is faster because
1)gravity is 9.8 meters/second/second (every second increases 9.8m/s).
2)light is about 186,000 miles per second
3) all objects eventually hit terminal velocity at which point they do not accelerate any further and all terminal velocities are well below 186,000 miler per second.
No way gravity can overtake speed of light except in a black hole in which case object would never go faster then the light anyway since everything pulled into the event horizon

I think that's an impossible situation, but assuming that it doesn't pass the center of gravitation ever, then yes, I guess an object could go faster than the speed of light eventually.
