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 well-known equations of all time: E=mc².
As most people would say that the equation deals with the Mass–energy equivalence. Meaning that energy and matter are basically the same thing. But is that really all it says? No, as it turns out, totally not. PBS Space Time gives a mind-bending explanation:
