In the world of physics there always seems to be one more question.
John Dalton talked in terms of billiard balls, then people asked, "What's inside?"
Through a plethora of people we now have super hadron colliders... still searching for the next (last?) particle.
Always seeking, never finding the end.
Isn't that the quest for knowledge, though? And vision?
How about eternity? No end in sight!
Where do those semi-obtuse thoughts take you? Anyplace interesting?
