Answer:

Though it's surprising but it will smash our home planet into pieces of rocks. According to theory of relativity

E=mc2

let mass of needle is 1 g then energy is

E = (3*10^8)^2

=9*10^16 J

Which is a huge amount of energy.

Answer:

The answer is that the needle will bury under the underside soil as the needle is small and the area is more the pressure acting on needle is more so it will burry under the earths layer

Explanation:

The only way a “needle” could travel at the speed of light is if it were massless, because it is immposible to accelerate an object to the speed of light. Our only option is to turn the needle into a beam of pure light, so that it can actually travel at the speed of light, which then means that the needle isn’t a needle anymore . Technically this question cannot be answered
