Bumping up against a parallel universe
EarthSky

An analysis of the cosmic microwave background revealed bright spots, possible imprints left when an alternate universe bumped ours shortly after the Big Bang.

A scientist has evidence of our universe and a parallel universe bumping into one another, in the distant past. An analysis by Ranga-Ram Chary of a map of the cosmic microwave background revealed eerie glowing patches that he thinks might be imprints left in the encounter. The map comes from data gathered by a space observatory called Planck, operated by the European Space Agency (ESA) from 2009 to 2013, and Chary is a researcher at the at the U.S. Planck Data Center at CalTech. ...

Many universes? Until recent decades, most astronomers would have told you that, by definition, the word universe means all there is. That word was used to describe all space, time, matter, physical laws and constants. But now a new word – multiverse – has entered the language of scientists.

Not all scientists agree, but some – including Stephen Hawking, for example, and Alan Guth of MIT – believe there’s scientific justification for a multiverse, many universes springing into being, possibly existing simultaneously, each possibly with its own physics. If true, then our universe of stars and galaxies is just a small part of this vast assemblage of many universes.

The New York Times was describing a brief history of the multiverse when it explained that the argument for it comes from Big Bang theory:

… according to the standard model, shortly after the universe exploded into existence about 14 billion years ago, it suddenly jumped in size by an enormous factor. This ‘inflation’ can best be understood by imagining that the observable universe is, relatively speaking, a tiny blob of space buried deep within a vast labyrinth of interconnected cosmic regions.

Under this theory, if you took a God’s-eye view of the multiverse, you would see big bangs aplenty generating a tangled melee of universes enveloped in a superstructure of frenetically inflating space.

Though individual universes may live and die, the multiverse is forever.

The cosmic microwave background – first theorized in the 1940s and first observed in 1965 by Arno Penzias and Robert Wilson at the Bell Telephone Laboratories in New Jersey – is a tool for studying the possibility of alternate universes.

Theorists determined several years ago that, if two universes started out close enough that they touched before expanding space pushed them apart, they could leave an imprint – a bruise – on each other that might show up on the cosmic microwave background.

2. As the Zen master said, "We'll see."

Cultural context:

BTW, from Charlie Wilson's War starring Tom Hanks and Philip Seymour Hoffman (seen here) and Julia Roberts and Ned Beatty. A film based on fact filmed by Mike Nichols (his last), script by Aaron Sorkin. Funny, but events had a tragic result.

That ball keeps bouncing.

The hypothesis in the OP is highly unlikely, which is what most of the cosmologists are saying. Certainly this needs peer review and replication, at minimum.

3. But... There is no "close enough" if there isn't some sort of space-time.

We don't know what kind of space-time equivalent the other universe has.
We don't know whether the continuum between our universe and the other one even HAS a metric.
