I remember watching a program many years ago about the possibility of alien civilizations in our galaxy. I wish I could remember what the name of it
was but I saw it about 20 years ago and I have drank a lot of beer since then. The show proposed different phenomenon that could be regarded as proof.
I didn’t really put much thought into most of what the show touched o; except one idea.
They explored the possibility that lunar and solar eclipses could be viewed as possible alien life. Not just the partial ones but the full blown total
eclipses. Apparently, and I don’t know this for sure, earth is the only planet in the solar system that experiences total eclipses. It has
everything to do with the size and distance relationship between the moon and earth.
The earth is constantly moving further from the sun and the moon is also constantly moving further from the earth. Albeit these changes in distance
are miniscule when looked at in the short term. However, in the long term these changes in distance are significant.
Moon moves away from earth per year ~1.496” (3.8cm)
This equates to ~23,611miles/billion years
Distance to moon ~238,857 miles
Earth moves away from sun per year ~.59” (1.5cm)
This equates to ~9,311miles/billion years
Distance to sun ~92955817 miles
Solar system created ~3.8 billion years ago
So with this data let’s start some calculations. When the solar system was formed the moon was ~328,579 miles from earth. This means the moon is
~37% further away from earth than it was 3.8billion years ago. The distance then earth would have moved from the sun is ~35,382 miles. Not really much
of a difference to be a factor (>.1%).
Based on my calculations the moon would have appeared much larger in the sky 3.8billion years ago. This would have resulted in eclipses playing out
differently than they do today. Maybe this was all by design and eclipses were meant to be at their peak performance when we reached this stage of our
Just something to think about and I am certainly open to input and I’m deferring to anyone here with a better understanding of planetary mechanics.
