Is this song terrible or what?
The story of the Apostles speaks about a man of the apostle who did not believe Jesus was wounded. He said, "I do not believe in the wound unless I stick my hand in the wound", and then Jesus lets him stick his hand in the wound and the apostle cried out that he was sorry and he believes!
This is the reality of the abstract logical universe. There are some things left to the believers, and some things left to the non-believers! Theoretical Physics is exactly the thing that drives this abstract logical world into a logical perceivable world.
