Do you know: What might happen if you fall into a black hole? That the Universe does not have an edge? That the reason it gets dark at night is proof of the Big Bang? That cosmic particles time-travel through the atmosphere defying death? That our past, present and future might all coexist "out there"? With two remarkable ideas, Albert Einstein revolutionized our view of the Universe. His first was that nothing can travel faster than light-the ultimate speed limit. This simple fact leads to the unavoidable conclusion that space and time must be linked together forever as Spacetime. With his second monumental insight, Einstein showed how Spacetime is warped and stretched by the gravity of…
