A Needle At The Speed Of Light?

This ridiculous article on Unilad shows that the lunatics have again escaped from the asylum.

The piece describes the damage that a needle travelling at the speed of light would do if it hit the earth. The article claims that it is based on a theoretical study (actually, a computer simulation).

There are several huge problems with their hypothesis, all of them resulting from the theory of special relativity:

  1. To accelerate a needle (or any normal matter) to the speed of light is impossible,
  2. If it were possible, accelerating something to the speed of light would require an infinite amount of energy (and take infinite time),
  3. Of course, if something with infinite kinetic energy hit the earth, it would do an infinite amount of damage, not only to our planet, but to the whole universe.

The other huge problem with the article is the computer simulation: computer programs are inherently incapable of handling infinite numbers, so the creator of the video is not being honest with his readers.

In contrast to the predictions of special relativity, the video in the Unilad article suggests several possible outcomes, ranging from minimal damage to the destruction of earth, but no further afield.

Can we please stop with these ridiculous "studies"? They are just confusing people with bad science masquerading as real science.
