The Edges Of The Universe And "Dark Flow"
From National Geographic:
On the outskirts of creation, unknown, unseen "structures" are tugging on our universe like cosmic magnets, a controversial new study says. Everything in the known universe is said to be racing toward the massive clumps of matter at more than 2 million miles (3.2 million kilometers) an hour—a movement the researchers have dubbed dark flow.And I'll wager to bet the "dark flow" doesn't much care about your weekend plans, or your 3PM staff meeting.The presence of the extra-universal matter suggests that our universe is part of something bigger—a multiverse—and that whatever is out there is very different from the universe we know, according to study leader Alexander Kashlinsky, an astrophysicist at NASA's Goddard Space Flight Center in Maryland.
