Einstein‘s ironclad theories finally did us in.
Time was a barrier no human consciousness could overcome.
It did not matter whether there was life out here.Our backyard was too large, and our cosmic neighbourhood too vast to explore.
In the end we were all alone, trapped in fragile bodies, consciousness encased in fragile skulls too weak for the harshness of empty space-too stubborn to reside in mechanical contraptions built to last in space.
What was sent out finally was DNA material, in suspended animation, encased in all sorts of protective layers,in hopes that there was somethng out there to generate and eke out consciousness from it, and perhaps resurrect something that qualified/quantified human enough, whatever that might be.
Of all the protective layers, the final layer was that of the densest layer of hope that mankind could muster, because when it finally came down to such matters, they were sure hope was the only indestructible force in the universe.
