What happens when a needle hits the earth moving with the speed of light?

This does not seem to be that dangerous in the first instance, but let's rethink it again.

We are making the needle move at the speed of light, What are its implications?

Let’s see what science has to say, We know about the very famous MASS ENERGY EQUIVALENCE,

E=mC2,

Now, let's move forward with this in mind. The maximum weight of a needle on average is 0.584 g and the speed of light is ~ 3x108 m/s. Now substituting this value in the equation we get a value of 5.21 x 1013 J.

Just for reference, the amount of energy released by the atomic bomb during the famous explosion of Hiroshima and Nagasaki by America in the second world war released a rough amount of 1.5x 1012 J. So you can understand the amount of energy it would carry.

Now comes the most interesting part, now that I have given a perspective with the numbers, let us understand what would happen with that energy, because of the law of conservation of energy the enormous amount of kinetic energy that the needle possesses will be distributed on the surface of the earth evenly which eventually will pierce through the core of the earth which is full of magnum and plasma, and this will create cracks across the earth and provide exit point to this enormously heated plasma to escape, and in simple terms which means, an MASSIVE EXPLOSION, nothing like ever recorded in human history or even before humans too and everything we know off, everything on earth and inside earth would explode within the time of a blink of an eye, as this will cascade an event in the solar system as the debris emerging from the explosion of the earth would travel across and beyond earth destroying other planets too.

All this just because of a needle, is fascinating, but there is another view that physicists have, some physicists believe that because of too much kinetic energy and enormous inertia, the needle will simply pierce the earth through, and this will happen so quickly that no one will even notice. The needle will come out the other side of the planet and continue its flight. Perhaps, due to interaction with the mantle and the Earth’s crust, earthquakes will begin to occur but, they are unlikely to be strong. Ultimately humanity will easily survive.

Now, there is no way this can ever be tested As we don’t have a technology that can make matter of any kind to move at the speed of Light, so probably we never will be able to test this.

Let me know of any other hypothetical scenarios you have ever thought of and we would try and discuss and evaluate how much it can or cannot be true.
