The Possibility Of Panspermia In The Deep Cosmos By Means Of The Planetary Dust Grains
By obtaining the assumption that planetary dust particles can escape from the gravitational attraction of a planet, we consider the possibility for the dust grains to leave the star’s system by means of the radiation pressure.
By taking the typical dust parameters into account, we consider their dynamics and show that they can reach the deep cosmos, taking part in panspermia.
It has been shown that, during 5 billion years, the dust grains will reach 105 stellar systems, and by taking the Drake equation into account, it has been shown that the whole galaxy will be full of planetary dust particles.
