Tiny, entangled universes that form or fizzle out - a theory of the quantum multiverse

In recent decades, cosmic inflation theory has largely settled the once-daunting existential question of ‘How did the Universe begin?’ for most physicists. That is to say that, from a singular hot, dense and small starting point, the just-right conditions for the emergence of the Universe were met. This set the stage for the unfathomably rapid expansion of the Big Bang and the emergent laws of physics that we observe today.

However, as the Albanian American cosmologist Laura Mersini-Houghton explains to the American host Robert Lawrence Kuhn in this instalment of his series Closer to Truth, the first fraction of a second of the Universe, just before the Big Bang, is still a wide-open scientific frontier. Exploring the fertile ground where observation meets theory, Mersini-Houghton explains why she believes the improbable existence of our Universe suggests a quantum multiverse in which some potential universes fizzle into oblivion, and others form classical universes like our own.

It’s among the oldest questions because we humans are rightly obsessed by ultimate origins. Cosmologists can now explain back to the first 10-36 second of our universe - with the theory of “cosmic inflation”, which is what put the “bang” into the Big Bang. What is recent thinking on the beginning of the universe?

1. A common theme in a lot of Science Fiction.

So nothing new.

Let the theoretical astronomers carry on though, if that makes them happy.

2. Begs the question: Did Trump's penchant to live intensely and exclusively in his own universe............

draw his followers, inexorably, into his version of reality? Was corruption even a property of existence before Trump's explosion onto the screens of our TeeVees? Can a world after Trump's inevitable implosion fundamentally exist or will the entanglements of so many political players cause the whole fabric of space-time to simply follow him into a black hole of talking heads, trapping the rest of us in an eternally seduced stasis of desperate psychosis?

4. Cosmic Inflation may explain Trump's fat ass

But how does that black-hole of an SOB-narcissist manage to spawn such a multi-verse of MAGAts ?

3. It's all compacted waves I tells ya!

Exotic properties to be sure but does explain how celestial bodies can be zapped into nothingness in a fraction of a second when a nearby gravitar shoots a pulse their way.
