ppt presentation about the parallel universes theory

1. PARALLEL UNIVERSES

2. In the 1950s, the idea of Parallel
Universes, also known as
Multiverses, was proposed. The idea
of having distant universes identical
to ours, but with different outcomes
and slightly different events, is an
interesting topic. Proof of Parallel
Universes could change science
forever and could be the key to time
travel!

3. What is the universe?
The Universe is everything we can
touch, feel, sense, measure or
detect. It includes living things,
planets, stars, galaxies, dust clouds,
light, and even time. ... The Universe
contains billions of galaxies, each
containing millions or billions of
stars. The space between the stars
and galaxies is largely empty.

4. How big is the universe?
The universe is in fact, way larger than we think since the 93 BILLION LIGHT YEARS (9 trillion
kilometers in diameter) estimation is just the observable universe as some quantum physicists
explain in their different theories about how big the universe is!

5. What is the
multiverse?
It is a hypothetical collection of
potentially diverse observable
universes, each of which would
comprise everything that is
experimentally accessible by a
connected community of observers.
The observable known universe,
which is accessible to telescopes, is
about 93 billion light-years across.

6. Hugh Everett III
• In 1954, a Princeton University graduate
by the name of Hugh Everett III
proposed the idea of parallel universes.
• There would be multiple universes that
branch out from ours. They would be
related to each other, but the outcomes
would be different.
• Many scientists think that it is silly to
believe in these universes, however,
they are called “radical”.

7. Neils Bohr
• Neils Bohr, who also proposed a
groundbreaking idea of how atoms are
formed, also proposed an idea on how
Parallel Universes could exist.
• The observations on these weird areas
in space that conflict with the laws of
physics, change how they react. For
instance, the forces on the object
change.

8. LEVEL ONE
LEVEL TWO
LEVEL THREE
LEVEL FOUR
(An extension to our
observable universe)
(The bubble universe)
(Many worlds)
(Ultimate mathematical
universe)
Max Tegmark's four levels of multiverses

9. Extension theory
Space in our universe goes on far
beyond that which we can see, and
perhaps goes on forever — which
would mean that infinitely many
other regions exist in our own pocket
universe, regions like our observable
universe, where the laws of physics
are the same.

10. Bubble universe theory
Infinitely many other regions
exist in the same space-time as
that of our universe, but they
are disconnected permanently
from our own pocket universe,
and within each of them the
laws of physics are different
(described by Linde's eternal
chaotic inflation and
potentially the string theory
landscape).

11. Many worlds
A kind of space different from the space-
time of our universe exists where the laws
of quantum mechanics generate multiple
universes via innumerable branchings (This
is based on taking seriously the quantum
wave function) The universe branches into
different whole-world realities with every
tick of time, whether at every Planck time,
which is 10^-43 seconds (the time it takes
a photon, traveling at the speed of light, to
travel one Planck length, 10^-35 m), or at
every instant of time when an observation
is made.

12. Ultimate
mathematical
universe
• The ultimate mathematical universe
hypothesis is Max Tegmark’s hypothesis.
• This level considers all universes to be
equally real which can be described by
different extremely complex
mathematical structures.
