I don't care what anyone says about time, they live here not out there.
Look at what we have today compared to 1000 years ago. Where was science then compared to today? Now where will things be 1000 years from now. Wil there be new discovers, if not then why not stop searching? We don't know how things might be like out in the vastness of space.
Think how puny we are when looking at the big picture but we know how it all works

Did we know how it all worked 1000 years ago?
Speaking of Einstein, he did say this....
- Every one who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the Universe-a spirit vastly superior to that of man, and one in the face of which we with our modest powers must feel humble.
