Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it

Dark side of the moon

The solar system began to form about… 4.6 billion years ago. Give or take a couple of million…

Our moon was potentially ‘habitable’ for about 500 million years after its formation… about 3.5 billion years ago. During its ‘brief’ tenure as a satellite capable of supporting life it had enough water to maintain an atmosphere (of about 1% of earths current atmosphere) which would have been enough for pools of water to form. The volcanic action also helped replenish the atmosphere.

Perhaps most importantly is that there is evidence to suggest that the Moon had a magnetic field which would have protected it from solar and cosmic radiation.

It is unlikely that life would have gotten past the single cell organism phase in that ‘brief’ window, but still, there was potential there.

Perhaps instead of a tidal locked hunk of rock we should consider the moon more like a giant microbial graveyard circling round the earth… a testament that life in the universe is harsh and unforgiving, a portent of things to come.

While I’d like to be more than an a casual commentator on all things cosmological it is an area of for which I am cognitively unsuited. Still, what I lack in accuracy and understanding  I make up for with enthusiasm. Find more posts

      Thanks. Although that worries me. I thought it was decidedly ‘meh’.
