The world is full of coincidences. Today just proves that. A meteor about the size of a fridge apparently entered the atmosphere over Russia today travelling at supersonic speeds.
As it slowed down in the atmosphere and went subsonic it produced a large sonic boom. It broke up and landed with a large bump in a frozen lake somewhere in the Ural mountain region.
The resulting shock waves caused damage to the buildings in the vicinity injuring maybe 900 odd people. According to experts this maybe the largest to hit the Earth in 100 years. A once in a lifetime collision.
The coincidence? Well at almost the same moment an unrelated asteroid the size of an Olympic swimming pool was passing close to the Earth within the orbits of some of the planets geostationary satellites. This is a once in 200 year occurrence.
Now that is a coincidence.
