What if i throw a needle with the speed of light on Earth neglecting it's air friction nd assuming it to hit earth with speed of Light !!
Answers
Assuming that the needle can be at something near speed of light without considering the amount of energy needed, what happens with the needle? Having mass, it would have infinity momentum, which would result in a gravitational field so strong that the needle’s atoms would be affected and it surely would cease to be a needle. What would happen with time in this gravitational field? Can a collision be instantaneous? Isn’t needed a distance between two objects directed towards each other at a time “t” for them to collide at a posterior time t’ > t? Are these reasonable questions? If a collision can’t be instantaneous, an observer at a distance greater than zero would never see the collision as time would never “pass” and the distance between the needle and the Earth would never be covered. So nothing happens. This moment really takes forever. The needle is traped. The rest of the universe is sucked by the field at the speed of light and colapses into a single point. After t + ∞, a new Big Bang occurs. Soon or later, the needle will strike again.
Answer:
Because of this, it doesn't matter what the mass or velocity of the object the particle at the speed of light is striking, since it has infinite momentum, the collision will result in a massive loss of kinetic energy.
