We term the space & beyond system of matter and energy as Universe. The word Universe demonstrates the Uniqueness of the ‘UNIVERSE’. But still we are not able to find one percent of even our solar system, hence many unsolved, unknown, mysteries are present in both, Astrophysics and the Universe.
But is our universe unique? Why should there not be many universes (…..oops now I should say them Multiverses or simply Verses.) ? Existence of Multiverse is an Unsolved problem in Physics and requires proof.
Andrei Linde‘s Concept of Multiverse
Andrei Linde at Stanford had brought forward the cosmological model of a multiverse, which he called the “self-reproducing-inflationary universe.” His theory was based upon Alan Guth‘s inflation model, and included multiple universes woven together in some kind of spacetime foam. Each universe exists in a closed volume of space and time.
Linde’s model, based on advanced principles of quantum physics, defines easy visualisation. Quite simplified, it suggests quantum fluctuations in the universe’s inflationary expansion period to have a wavelike character.
Linde theorizes that these waves can “freeze” atop one another, thus magnifying their effect.
The stacked-up quantum waves can in turn create such intense disruptions in scalar fields -the underlying fields that determine the behaviour of elementary particles- that they exceed a critical mass and start procreating new inflationary domains. The multiverse, Linde contends, is like a growing fractal, sprouting inflationary domains, with each domain spreading and cooling into a new universe.
If Linde is correct, our universe is just one of the sprouts. The theory neatly straddles two ancient ideas about the universe: that it had a definite beginning, and that it had existed forever. In Linde’s view, each particular part of the multiverse, including our part, began from a singularity somewhere in the past, but that singularity was just one of an endless series that was spawned before it and will continue after it.
