INTRO: Unexplained shapes in the sky could be evidence of a universe that existed before ours, scientists have said. Astronomers claim that very unusual points, spotted in the early universe, appear to be sources of vast amounts of information. It is still not clear why those strange parts of the sky would behave in such an outstanding way.
But researchers have now claimed that those spots of energy could be the consequence of "conformal cyclic cosmology" [CCC], a theory that suggests that our universe existed in another form before ours. They could have formed from black holes, the researchers suggest in a new paper. As such, those unexplained swirling areas in the sky could be the leftovers of another universe. “What we claim we’re seeing is the final remnant after a black hole has evaporated away in the previous aeon," Roger Penrose, a mathematical physicist at Oxford Universe and one of the authors of the study, told New Scientist, which first reported the news.

[...] Penrose’s idea has a lot of problems. To begin with, it’s not clear just how the old and new Universes would match up. Penrose proposes a conformal mapping between the two, but his method lacks clear details. There’s also the problem of proving such an idea. Since a cyclic cosmology would look just like a big bang cosmology, how would CCC ever become more than just wild speculation? In a recent paper [2015 actually], Penrose and a colleague propose a possible solution, and it involves alien messages from an earlier Universe.
Such a message, Penrose argues, could be encoded in the cosmic microwave background (CMB). While the CMB is fairly uniform, it does have small fluctuations in temperature. The scale at which these fluctuations occur tells us about the overall structure of our Universe. But there are also regions where the fluctuations are more extreme than we’d expect. These anomalies aren’t highly unusual, but they are interesting enough that some have speculated they might be caused by another Universe. But in Conformal Cyclic Cosmology, such fluctuations aren’t likely to appear because the new and old Universes connect when they are smooth. But if the CCC idea is correct, some super-advanced civilization in the old Universe could intentionally imprint the new Universe with a signal or message. In principle we should be able to detect such a message. (MORE)
