Hi All,
We don't have a lot of time on our hands. Only a few million years or if all goes well 4 billion years. Average asteroid strike rate is one every 100 million years. (the ones big enough to snuff 90% of life)
We go back 3,000 years Average man did not venture more than 12klms from home in a lifetime.
Back 300 years, 20klms
Back 100 yrs, 50klms No one more than 30,000klms (Space travel)
Back 50yrs, 500klms No one more than 100,000klms.
Back 10yrs, Could this be just the start. Moon landings.
There are so many things that are not understood. In this universe.
It was said many times. "Man would never fly"
A cannon ball will fall faster than a musket ball.
The sun is made of burning coal.
Planes can not fly faster than sound because of the "barrier"
Cheers Marty
Do we now have negative thoughts that man will never reach the stars?
