Can an object become a black hole by reaching 99.9% the speed of light?

[Giulio B.]

If we would get to 99,9...% c will we become a black hole?

No. See for instance

Black holes are one of the most fascinating and mysterious objects in the universe. They are created when a massive star collapses under its own gravity, causing the core to shrink to a point of infinite density known as a singularity. This process is known as gravitational collapse.

In order for an object to become a black hole, it needs to have a certain amount of mass. This is known as the Schwarzschild radius, which is directly proportional to the mass of the object. The more massive the object, the larger its Schwarzschild radius and the stronger its gravitational pull.

In theory, if an object were to reach a velocity of 99.9% the speed of light (c), it would increase in mass due to the effects of special relativity. However, this increase in mass would not be enough for the object to become a black hole. It would need to have an incredibly large mass to reach the Schwarzschild radius and collapse into a black hole.

Furthermore, reaching such a high velocity is currently not possible for any known object. The speed of light is the fastest speed possible in the universe and it would take an infinite amount of energy to accelerate an object to that speed.

In conclusion, simply reaching 99.9% the speed of light would not cause an object to become a black hole. It would require an immense amount of mass and energy for an object to collapse into a black hole.
