More than four billion space bodies, a.k.a., meteoroids fall into the Earth’s gravity well every day. This moniker covers everything in size greater than interplanetary dust, but less than that of an asteroid. These are small stones in the majority which quickly burn up in the terrestrial atmosphere. Only a few can pass this barrier.
Meteoroids that reach the Earth’s surface are then called meteorites. At the same time they do not pose a particular danger. Although occasionally they can make local residents nervous, as happened recently in Chelyabinsk (2013 in Russia). But what if we increase the velocity of the meteorite to the speed of light?
