What happens if two particles collide at the speed of light?
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 mass multiplied by the speed of light squared).
Can two objects move away from each other faster than the speed of light?
general relativity. It’s true that in special relativity, nothing can move faster than light. That’s the domain of general relativity, and general relativity says: who cares! That galaxy can have any speed it wants, as long as it stays way far away, and not up next to your face.
Can relative velocity be greater than speed of light?
If we transition to general relativity and an expanding universe, then for objects that are separated with a big enough distance, their relative speed can exceed the speed of light in such a way that they can not send signals between each other.
What happens when you collide particles?
When they collide, interesting things can happen. In most proton collisions the quarks and gluons inside the two protons interact to form a wide array of low-energy, ordinary particles. Occasionally, heavier particles are produced, or energetic particles paired with their anti-particles.
What happens when two electrons collide?
Colliding two electrons will always produce two scattered electrons, and it may sometimes produce some photons from initial and final state radiation. Rarely some extra particle-antiparticle pair (like electron and positron) can pop up.
Why can’t we exceed the speed of light?
The speed of light in a vacuum is an absolute cosmic speed limit. According to the laws of physics, as we approach light speed, we have to provide more and more energy to make an object move. In order to reach the speed of light, you’d need an infinite amount of energy, and that’s impossible!
When two protons moving at high speed collide they change into?
What happens when 2 protons get near each other?
When two Protons fuse together, one of them decays into a Neutron. Our new nucleus now has one Proton and one Neutron. It is still Hydrogen, because there is still the same number of Protons, but it is a different type, or isotope, of Hydrogen.
Is the speed of light principle violated by 2 photons moving together?
The relative speed of 2 objects is not itself the speed of a ‘thing’, therefore the speed of light principle is not violated by saying that 2 photons moving in opposite directions move away from each other at a relative speed of 2C.
Why is the speed of light not equal to the mass?
And also that if some particle was once going slower than speed of light, it will always do so. You have to understand special relativity. It’s basically because Newtonian mechanics breaks down at speeds close to the speed of light and F = m a is false. It’s basically because your mass isn’t constant, it varies based on your speed.
Why is the speed of light always C in SR?
Also, the Alcubiere drive (and metric) allows a warp bubble to travel (expand) and supraluminal speeds (providing one ignores theoretical problems with building one:) From SR, the speed of light is always c in every intertial frame. Accelerating a particle to c would mean the velocity of light wasn’t c in the frame of the particle.
What happens when you push an object at the speed of light?
This is what gives us the ‘common sense’ that if you push something a little bit harder, it will go a little bit faster. But as the object’s speed approaches the speed of light, the effect of applying force to the object is altered. Rather than the object’s speed increasing, its mass begins to increase instead.
