What if there were multiple versions of ourselves, living parallel lives in parallel universes?

With modern advances in cosmology and particle physics, we’re redefining our ideas of what exactly our own universe is made of, how it got started, and whether there are others out there.

When it comes to considering what might lie beyond our observable universe, there a few popular theories that emerge.

We have the Type 1 Multiverse, a Quantum Multiverse, a Mirror Universe, Bubble Universes, and Baby Universes inside of black holes.

When you consider the possibilities of what might exist when it comes to universes outside our own, the theories are pretty fascinating.

Find out more about the expansion of our own universe, the physics of universes beyond what we can observe, and how close we are to discovering parallel universes on this episode of How Close Are We?

Scientists are searching for a mirror universe. It could be sitting right in front of you.
“The mirror world, assuming it exists, would have its own laws of mirror-physics and its own mirror-history. You wouldn’t find a mirror version of yourself there (and no evil Spock with a goatee — sorry “Star Trek” fans). But current theory allows that you might find mirror atoms and mirror rocks, maybe even mirror planets and stars. Collectively, they could form an entire shadow world, just as real as our own but almost completely cut off from us.”

Parallel Universes: Theories & Evidence
“The expansion at the beginning of the universe took place exponentially because there was so much ‘energy inherent to space itself,’ [Siegel] said. But over time, that inflation obviously slowed — those particles of matter created at the Big Bang are not continuing to expand… [a]mong his conclusions: that means that multiverses would have different rates of inflation and different times (longer or shorter) for inflation. This decreases the possibilities of universes similar to our own.”

Is there another ‘you’ out there in a parallel Universe?
“The Universe, as far as the most powerful telescopes can see (even in theory), is vast, huge and massive. Including photons and neutrinos, it contains some 10⁹⁰ particles, clumped and clustered together into hundreds-of-billions-to-trillions of galaxies. Each one of those galaxies comes with around a trillion stars inside (on average), and they’re strewn across the cosmos in a sphere some 92 billion light years in diameter, from our perspective. But, despite what our intuition might tell us, that doesn’t mean we’re at the center of a finite Universe. In fact, the evidence indicates something quite to the contrary.”
How close are we to solving some of humanity’s biggest challenges? We go in search of experts, dive into the facts and comb through the research to find out just how close we are to changing the world.

Seeker explains every aspect of our world through a lens of science, inspiring a new generation of curious minds who want to know how today’s discoveries in science, math, engineering and technology are impacting our lives, and shaping our future. Our stories parse meaning from the noise in a world of rapidly changing information.
