Many Worlds Theory/ ‘Relative State’ formation of Quantum Mechanics/ Quantum
Multiverse: In different universes, this project is going by each/all of these names… and
infinite more.
What is it?
• An interpretation of the universe that proposes that all histories/possible outcomes of a
situation are present in another world
• developed by Hugh Everett III in the mid-1900’s.
• It doesn’t really have strong evidence which makes physicists skeptical and critical
How Does it work?
• Based on the idea that the universe is defined by two “transformations”
1) all strange things we imagine for ourselves would not happen because of rules
governing the universe
~ forces cause the world that we are familiar with (electromagnetic,
strong, weak, gravity)
Why wouldn’t the strange things happen?
• basically, some scientist came up with a way of summing up all
the different outcomes of things in the world (Sum Over Histories
by Feynman)
~ method sums up the different conceivable paths through
time and space of a particle (the measurement problem)
- even those that disobey our laws
- figured out that the ones that disobeyed the laws
and forces that govern our life had amplitudes
that summed to zero.
- Only ways that abide by physical laws, stay
2) multiplicity of worlds transforms into one world
~ Schrodinger’s cat experiment (give a brief description)
• instead of believing that two realities are both possibly
happening and not happening, accept that they both are happening
~ just in different worlds
• if we were to open the box and look, our being would get split in
half and we would see both realities
~ Everett believes that we split into all the different possibilities of a given
situation
How can he determine that?
• The original idea is that small particles travel as probability
waves
~ a particle gives up its position when it has momentum,
we can figure out its position when it has zero momentum.
- position and momentum cannot be known at the
same time
• Then comes along Hugh Everett III, who determines that one
probabilistic outcome is as real as any other
~ in a given system with an infinite number of worlds
identical to our present, imagine one particle moving—it
will move to a different position in each location and
therefore the outcome is different in all the different worlds
~ It’s crazy. I know. Basically, to help you think about
this… imagine someone looking at a clock, what happens in
between the present and looking at something, is that we split into
all the different abilities (in many universes) until we actually look
at it…then we are in one state
- Then the copies go off in their own universes,
unknowing
o All these universes make up the
“multiverse”
o There are trillions and trillions of
versions of yourself
Why is it important?
• It’s most important for Quantum Mechanics Physicists
~ Many Worlds Theory gives scientists the ability to consider quantum mechanics
universal.
• no division between classical and quantum mechanical world
What?!
• Technically, the theory (however crazy it may be) hasn’t been mathematically proved
incorrect. So while you’re standing here in shock reading this poster, in another world…
you’re entranced by it.
