Physicists Think They've Spotted the Ghosts of Black Holes from Another Universe


By Rafi Letzter, Staff Writer | August 21, 2018 01:48pm ET

We are not living in the first universe. There were other universes, in other eons, before ours, a group of physicists has said. Like ours, these universes were full of black holes. And we can detect traces of those long-dead black holes in the cosmic microwave background (CMB) the radioactive remnant of our universe's violent birth.

At least, that's the somewhat eccentric view of the group of theorists, including the prominent Oxford University mathematical physicist Roger Penrose (also an important Stephen Hawking collaborator). Penrose and his acolytes argue for a modified version of the Big Bang.

In Penrose and similarly-inclined physicists' history of space and time (which they call conformal cyclic cosmology, or CCC), universes bubble up, expand and die in sequence, with black holes from each leaving traces in the universes that follow. And in a new paper released Aug. 6 in the preprint journal arXiv, Penrose, along with State University of New York Maritime College mathematician Daniel An and University of Warsaw theoretical physicist Krzysztof Meissner, argued that those traces are visible in existing data from the CMB.

An explained how these traces form and survive from one eon to the next. [What's That? Your Physics Questions Answered]

4. Wow!

Just read this to the hubs, physicist, who said that's what he had proposed too.

Modified version of the Big Bang still doesn't negate The Big Bang Theory, just adds to it.

5. what's the mechanism?

 

if all matter/energy is contained in a single point, how does the fact that some of that (or even all of it) was once Hawking radiation impart any sort of pattern into a new Big Bang universe?
