Modern physics assumes the universe is the same all over... but that might not be the case. Until recently, physics held that the universe was contracting... now we're stuck with dark energy. But one moderately insane new theory could explain it all.
The discovery, just over a decade ago, that the universe is accelerating its expansion rocked astrophysics and forced theorists to invoke the existence of dark energy, a mysterious force that drove this expansion and accounted for as much as 74% of all the mass-energy in the universe. It's not exactly the most elegant solution, but it's the best explanation for the evidence currently available. For a more detailed primer on why dark energy makes more sense than all the alternatives, check out Dr. Dave Goldberg's primer.
