What is the theoretical and realistic maximum speed of object falling onto or projected into a black hole?

From the event horizon to the singularity (although probably not an actual singularity with infinite mass and zero dimensions, but that's a different subject), spacetime has undergone an intense amount of stretching that approaches infinite curvature at the singularity. The curvature of space is what determines the gravitational field strength, which is represented by the acceleration due to gravity. On Earth, our acceleration due to gravity is about 9.8 m/s^2.





In a blackhole, that field strength grows without bound because of the unbounded curvature so to speak. Therefore, the maximum speed should be unbounded, since the acceleration is unbounded, but we also have to consider how long the object is under the influence of that acceleration. (not to mention the speed of light being the speed limit as well)





The time it takes an object to reach the singularity once it has breached the event horizon is fractions of a second, so there isn't enough time for the object to reach a great speed. Of course you could argue that the blackhole is the size of a galaxy, which would give the object more time; however, in a blackhole that size, it would take a little longer, but not much. Besides, the the farther away one is from the singularity, the less intense the curvature is, so it would take some of that extra time just to get to the extremely intense curvature.





Here is another interesting feature: when you solve the equations inside a blackhole for velocity, it is always negative, meaning the velocity is directed towards the singularity. It can't be positive, which means once you enter the event horizon, there is only one way to go, and there is nothing you can do to stop it.





Also, you have to consider the intense tidal gravitational forces. Because the gravity is so intense, there is an appreciable difference of gravity's pull between your head and feet (assuming you go in feet first). Because this difference is so great, your body would be subject to tidal forces (like the tidal forces the Earth experiences from the moon), which means you will be stretched and crushed from the sides.What is the theoretical and realistic maximum speed of object falling onto or projected into a black hole?
Anyone who asks what the realistic maximum speed of an object projected into a black hole should be shot with a bullet traveling 186,000 m/secWhat is the theoretical and realistic maximum speed of object falling onto or projected into a black hole?
Theoretically it can go up to, but not at the speed of light. realistically it would be pulverized and turned into energy giving off gamma rays in a matter of milliseconds, therefore not really traveling at all.
Maximum theoretical speed is ';just under'; the speed of light. The realistic speed is lower--incoming matter orbits in an accretion disk where a lot of its motion is converted to heat. A measurement was actually made of about 10% of light speed.
The ultimate speed limit is of course the speed of light... nothing that has any mass can go as fast as light. As a massive object approaches the speed of light it's mass INCREASES towards infinity, so you see for an object with mass to get to the speed of light it would require more and more energy to accelerate it the more massive it became until ultimately it would require an infinite amount of energy just to increase its velocity by one cm/sec.... not very likely now is it?
maximum speed would be the speed of light, although as matter approaches that speed it loses mass!
the theoretical speed is just under light speed , or light speed if we are talking about fotons.in reality....a wormhole has special properties...the event horizon,it's huge gravitational force, time distortion so the speed will be affected by all of them, makink it to bound to the specific conditions to determin
