Albert Einstein is still one
of the ultimate minds in history. His work in the fields of cosmology, physics
and mathematics are unquantifiable, but perhaps, the most significant works
were his concepts of general and special relativity.

Ultimately, they explain the
strangest things of the universe—from the gravity itself, to the outmost edges
of black holes. Somewhere along the way, he offered what is now one of the most
