Transcript Parallel Universes

Parallel Universes
Level 1: Regions Beyond Cosmic Horizon –
1. The universe is infinitely big and contains matter at
roughly the same distribution (as we see it) throughout the
universe.

2.Matter can combine in only so many different configurations.

a. Given an infinite amount of space, it stands to reason
there exists another portion of the universe in which an
exact duplicate of our world.

b. - and, in fact, our entire visible universe - exists.

Level 2: Other Post-Inflation Bubbles
1. Separate universes spring up as bubbles of spacetime
undergoing its own form of expansion
Level 2: Other Post-Inflation Bubbles
1.Separate universes spring up as bubbles of spacetime
undergoing its own form of expansion
2.The laws of physics in these universes could be very
different from our own.
Level 3: The Many Worlds of Quantum
Level 3: The Many Worlds of Quantum
1. Physics - According to this approach to quantum physics,
events unfold in every single possible way, just in different
universes.

2.Science fiction "alternate history" stories utilize this sort of a
parallel universe model, so it's the most well known outside of
physics.
Episode 33, season 2.
Level 4: Other Mathematical Structures –
1. This type of parallel universes is sort of a catch-all for other
mathematical structures which we can conceive of, but which
we don't observe as physical realities in our universe.

2.The Level 4 parallel universes are ones which are governed
by different equations from those that govern our universe.
3.Unlike Level 2 universes, it's not just different manifestations
of the same fundamental rules, but entirely different sets of
rules.
Quilted Multiverse
Because space is infinite, and because there are only so many different ways to put matter together,
Somewhere “out there” is an exact copy of the Earth, Moon and you.
This would be “level 1”

Somewhere “out there” is an exact copy of the Earth, Moon and you.
This would be “level 1”
Inflationary Multiverse
The “entire” universe is expanding, and ours is just one “bubble” of many “bubbles” popping into existence
as big bangs.
This would be levels 1 & 2

Cyclic Multiverse
Three dimensional “branes” are filling a multiverse, and when they rub against each other, it creates a “big
bang”. Ours is just one of many universes created by brane collisions.
Quantum Multiverse
1.This says that because (now this gets a bit “hairy”
a. Quantum mechanics says that anything “can” happen

the universe.

"Dave, stop. Stop, will you? Stop, Dave. Will
you stop, Dave?” So the supercomputer
HAL pleads with the implacable astronaut
Dave Bowman in a famous and weirdly
poignant scene toward the end of Stanley
Kubrick’s 2001: A Space Odyssey. Bowman,
having nearly been sent to a deep-space
death by the malfunctioning machine, is
calmly, coldly disconnecting the memory
circuits that control its artificial “ brain.
“Dave, my mind is going,” HAL says,
forlornly. “I can feel it. I can feel it.”

the universe
3.Thus creating a simulated multiverse whose reality is nearly as complex as our own.

Ultimate Multiverse
1.
In the most extreme version of looking at parallel universes, every single theory which could
possibly exist would have to exist in some form somewhere
Universe
Size
Atoms
Stop
Light
Speed
If there is a chance, even a very small chance, say
1/1,000,000,000th,
If the pool of chances is unending, then the outcome is a
certainty.
