Roughly every 26 million years, the earth suffers a massive extinction
event in which whole species of the ecosystem disappear.
In 1983, a scientists names Richard Muller came up with an interesting
theory to explain the almost regular intervals of mass extinction on earth.
It’s widely believed and accepted by the science community
that the extinction events are participated by impacts of comets and asteroids
impacts, but Muller devised to explain the almost regular events was rather
scandalous – what is the sun had an evil twin sister?
The Twin sister was called Nemesis which orbits the sun
after every 26 million years; it is possibly a red dwarf star making it
difficult to see. It is at a distance of 1 to 3 light years away which is further
than the nearest star to earth, Proxima centauri.
When Nemesis gets closer to the sun, thanks to the ellipse
orbit, it disturbs the Oort cloud, the grouping of icy comets and bodies at the
edge of our solar system, and sends them to collision towards the inner planets.
Recently a new planet was found, sedan which is three times
the distance from Pluto to sun, it was so much unexpected but why? The orbit of
this planet is also exceptional, it is highly elliptical supposing that
something is out there influencing its orbit by its gravitational force.
The hunt of Nemesis continues if it is really out there, if
it’s there will we protect our species when it returns?
