However, I also believe that we will never make contact with any of them (nor they with us) on account of the light barrier. I do not believe the light barrier will be conquered by any form of intelligent life and the many thousands of light-years to get from place to place at sub-light speeds will make intergalactic travel impractical because all living things have a finite life span.
At the "Turn of the Century," the "Greatest Physicists of the Time" Predicted that "All Great Physical Principles Had been Discovered."
Then Came "Atomic Theory & Radium, ETC.!"
We can NEVER BELIEVE that we "KNOW" the Farthest Extent of "Human Knowlege!"
Considering our Discoveries of "Life" in EXTREME Conditions, we can NEVER "Rule out" the Possibility of "Life," ANYWHERE!!
We ARE--as a Species--COMPELLED to Find Other Life; The MERE POSSIBILITY of "Life" Elsewhere is a "Siren Song" that we MUST Follow!!
