The things you find in National Geographic articles....
This is a scenario of our universe a few trillion years into the future. It goes something like this: our universe is one of several million universes all 'feeding' off of the same flow of energy, much as all of our planets orbit the same sun. Full of energy and life, these alternate realities are racing and growing faster than light can travel. What if one of these came hurdling toward us? All of a sudden, everything we know is thrown into a wall of different laws of physics, gravitation, and elements. The result- total annihilation on both ends. Survivors: zero
