by Summary:
What happens if you turn space-time upside-down? A parallel universe going in reverse. This universe that’s inside the “second cone” is too far down space-time for us to see. Time might seem to run backward there from our reference frame, Learned said. But beings in that universe would still see cause coming before effect, just like we do in ours. Time runs away from the Big Bang in that universe, just like it does in ours. "Away from the Big Bang" in that universe is the opposite direction from the direction of time in our universe. but it doesn't run "backward" in the way we might imagine. The details of how the CPT-symmetric universe leads to a 480 PeV neutrino are tricky — so tricky, Learned said, that few physicists beyond Boyle and his team understand them at all. "But

"But these guys are not nutcases," he said. "They're respected members of the field and they know what they're doing. Whether all of that complicated field theory is correct or not, I can't say."
