Yah, I posted this to FR a number of years ago. Planets are not formed by the accretion of a disk of rubble surrounding a sun. They are electrically ejected from the hearts of stars and are not that common in the size and distances from their sun as old uncle Carl Sagan would have us believe. The philosophical implications of this hypothesis are staggering.
Paradox states the sky should be full of radio signals and aliens flying around.
There are none of both, nothing,not one single signal.
Why?
MIT biochemists tackled this,cassette mutagenesis experiments suggest that the probability of attaining (at random) the correct sequencing for a short protein 100 amino acids long is about 1 in 10 to the 65 power.
Meaning life just cannot randomly appear out of nowhere.
