What happens if 2 protons collide at the speed of light?

Answer 1

The short answer is: they can't. Protons, or any other particle that has mass, can't go at the speed of light because it would take infinite energy to get it going that fast. In particle accelerators, they make protons collide at a speed very slightly less than the speed of light, something like 99.99% of the speed of light. It takes a lot of energy to get the protons going that fast, and all of that energy is released in the collision, hopefully making some interesting results.

Answer 2

If two protons were to collide at the speed of light, their masses would become infinite according to the theory of special relativity. This would require an infinite amount of energy, which is not physically possible. In reality, protons can never travel at the speed of light due to their mass.

Answer 3

There is no point in speculating since each spaceship would require an infinite amount of energy to accelerate up to the speed of light.

Answer 4

When two beams collide, all that energy packed into such a small vacuum of space explodes and creates mass in the form of subatomic particles (think of Einstein’s famous equation: energy equals...
