Therefore, interstellar panspermia events are related to the average density of stellar systems containing habitable planets.
Thus, typically of a chain reaction, either interstellar panspermia has proceeded to completion or it has not taken place at all.
The interstellar medium provides yet another illustration of convergent phenomena that occur at a cosmic level.
Also, the gas and dust of the interstellar medium will be involved in the exchange.
If we apply this ratio to dusty plasmas in the interstellar medium, the ratio becomes much less than unity.
These supernova explosions are a source of enrichment of the chemical composition of the interstellar medium.
Direct investigation, using interstellar travel (either by us or by them) seems impractical at best and impossible at worst.
At a point well beyond the solar system when considering missions to interstellar space, beamed core becomes superior.
