Earthquakes coming from space
After investigating the seismic movements that occurred between 1990 and 93, American researchers have suggested that two of them generated very special materials, something that came from space and crossed the Earth side by side at 400 kilometers per second.
This special matter is formed by quark u, quark d and quark s and is very dense. Imagine that a piece the size of a cell would weigh a ton on Earth. If one of them crosses the Earth, it would release five times more energy than the Hiroshima nuclear bomb and leave a very special mark on seismographs. Precisely, American researchers have found two of these tracks in the 1993 seismic records. In that year, two incidents were recorded without any other explanation.
On October 22, something entered Antarctica and left southern India 0.73 seconds later. On November 24, an object entered southern Australia and left near Antarctica at 0.15 seconds. It cannot be guaranteed that quark were rare, but they have no other explanation.
