Collection of the Multiverse Theory.

1. MULTIVERSE THEORY

2. 1. The multiverse (or meta-universe) is the hypothetical set of infinite or
finite possible universes (including the Universe we consistently experience)
that together comprise everything that exists: the entirety
of space, time, matter, and energy as well as the physical
laws and constants that describe them. The various universes within the
multiverse are also called "parallel universes" or "alternate universes".
WHAT IS MULTIVERSE?

3. 2. The structure of the multiverse, the nature of each universe within it
and the relationships among the various constituent universes, depend on the
specific multiverse hypothesis considered.
3. Multiple universes have been hypothesized
in cosmology, physics, astronomy, religion, philosophy, transpersonal
psychology, and fiction, particularly in science fiction and fantasy.
3. In these contexts, parallel universes are also called "alternate universes",
"quantum universes", "interpenetrating dimensions", "parallel dimensions",
"parallel worlds", "alternate realities", "alternate timelines", and "dimensional
planes", among other names.

The American philosopher and psychologist William James coined the term
multiverse in 1895, but in a different context.

5. DEBATES CONCERNING THE
THEROY.
1. The physics community continues to fiercely debate the multiverse
hypothesis. Prominent physicists disagree about whether the multiverse
may exist, and whether it is even a legitimate topic of scientific inquiry.
2. Serious concerns have been raised about whether attempts to exempt the
multiverse from experimental verification may erode public confidence in
science and ultimately damage the nature of fundamental physics.

6. THE SUPPORTERS
Some Philosophers and scientist bealive in this theory of the multiverse which
include Stephen Hawking, Brian Greene, Max Tegmark and others

7. THOSE WHO DISAGREES.
Scientists who are not proponents or who arew opposed the idea of the
multiverse include: Nobel Laureate Steven Weinberg Nobel laureate , Neil
Turok,, ETC

8. Multiverse theory has different kinds of hypothesis the commonly known are
from Max Tegmark and Brian Greene.
MULTIVERSE HYPOTHESES IN
PHYSICS

9. Cosmologist Max Tegmark has provided a taxonomy of universes beyond the
familiar observable universe.
The levels according to Tegmark's classification are arranged such that
subsequent levels can be understood to encompass and expand upon previous
levels, and they are briefly described below
MAX TEGMARK'S FOUR LEVELS

10. A generic prediction of chaotic inflation is an
infinite ergodic universe, which, being infinite, must
contain Hubble volumes realizing all initial conditions.
Accordingly, an infinite universe will contain an infinite number of
Hubble volumes, all having the same physical laws and physical
constants. In regard to configurations such as the distribution
of matter, almost all will differ from our Hubble volume. However,
because there are infinitely many, far beyond the cosmological
horizon, there will eventually be Hubble volumes with similar, and
even identical, configurations.
Tegmark estimates that an identical volume to ours should be
about 10 meters away from us. Given infinite space, there would, in
fact, be an infinite number of Hubble volumes identical to ours in
the Universe. This follows directly from the cosmological principle,
wherein it is assumed our Hubble volume is not special or unique.
LEVEL I: BEYOND OUR
COSMOLOGICAL HORIZON

11. "Bubble universes": every disk is a bubble universe (Universe 1 to
Universe 6 are different bubbles; they have physical constants that are
different from our universe); our universe is just one of the bubbles.
LEVEL II: UNIVERSES WITH
DIFFERENT PHYSICAL CONSTANTS

12. LEVEL II: UNIVERSES WITH
DIFFERENT PHYSICAL CONSTANTS

13. Hugh Everett's many-worlds interpretation (MWI) is one of several
mainstream interpretations of quantum mechanics. In brief, one aspect
of quantum mechanics is that certain observations cannot be predicted
absolutely. Instead, there is a range of possible observations, each with
a different probability. According to the MWI, each of these possible
observations corresponds to a different universe. Suppose a six-sided
die is thrown and that the result of the throw corresponds to a quantum
mechanics observable. All six possible ways the die can fall correspond
to six different universes.
LEVEL III: MANY-WORLDS
INTERPRETATION OF QUANTUM
MECHANICS

14. Tegmark argues that a level III multiverse does not contain more possibilities in the Hubble
volume than a level I-II multiverse. In effect, all the different "worlds" created by "splits" in
a level III multiverse with the same physical constants can be found in some Hubble
volume in a level I multiverse.
Tegmark writes that "The only difference between Level I and Level III is where
your doppelgängers reside. In Level I they live elsewhere in good old three-
dimensional space. I
n Level III they live on another quantum branch in infinite-dimensional Hilbert space."
Similarly, all level II bubble universes with different physical constants can in effect be
found as "worlds" created by "splits" at the moment of spontaneous symmetry breaking in
a level III multiverse. According to Yasunori Nomuraand Raphael Bousso and Leonard
Susskind, this is because global spacetime appearing in the (eternally) inflating multiverse is
a redundant concept. This implies that the multiverses of Level I, II, and III are, in fact, the
same thing. This hypothesis is referred to as "Multiverse = Quantum Many Worlds".
Related to the many-worlds idea are Richard Feynman's multiple histories interpretation and H.
Dieter Zeh's many-minds interpretation.
LEVEL III: MANY-WORLDS
INTERPRETATION OF QUANTUM
MECHANICS

15. LEVEL III: MANY-WORLDS
INTERPRETATION OF QUANTUM
MECHANICS

16. The ultimate ensemble or mathematical universe hypothesis is the
hypothesis of Tegmark himself. This level considers equally real all
universes that can be described by different mathematical structures.
Tegmark writes that "abstract mathematics is so general that any Theory
Of Everything (TOE) that is definable in purely formal terms
(independent of vague human terminology) is also a mathematical
structure.
For instance, a TOE involving a set of different types of entities
(denoted by words, say) and relations between them (denoted by
additional words) is nothing but what mathematicians call a set-
theoretical model, and one can generally find a formal system that it is a
model of." He argues this "implies that any conceivable parallel universe
theory can be described at Level IV" and "subsumes all other ensembles,
therefore brings closure to the hierarchy of multiverses, and there cannot
be say a Level V."
LEVEL IV: ULTIMATE ENSEMBLE

17. Jürgen Schmidhuber, however, says the "set of mathematical structures"
is not even well-defined, and admits only universe representations
describable by constructive mathematics, that is, computer programs. He
explicitly includes universe representations describable by non-halting
programs whose output bits converge after finite time, although the
convergence time itself may not be predictable by a halting program,
due to Kurt Gödel's limitations. He also explicitly discusses the more
restricted ensemble of quickly computable universes
LEVEL IV: ULTIMATE ENSEMBLE

18. LEVEL IV: ULTIMATE ENSEMBLE

19. American theoretical physicist and string theorist Brian Greene discussed nine
types of parallel universes:
BRIAN GREENE'S NINE TYPES

20. The quilted multiverse works only in an infinite universe. With an infinite
amount of space, every possible event will occur an infinite number of times.
However, the speed of light prevents us from being aware of these other
identical areas.
1. QUILTED

21. The inflationary multiverse is composed of various pockets where inflation
fields collapse and form new universes.
2. INFLATIONARY

22. The brane multiverse follows from M-theory and states that our universe is a
3-dimensional brane that exists with many others on a higher-dimensional
brane or "bulk". Particles are bound to their respective branes except for
gravity.
3. BRANE

24. The cyclic multiverse (via the ekpyrotic scenario) has multiple branes (each a
universe) that collided, causing Big Bangs. The universes bounce back and
pass through time, until they are pulled back together and again collide,
destroying the old contents and creating them anew.
4. CYCLIC

26. The landscape multiverse relies on string theory's Calabi–Yau shapes.
Quantum fluctuations drop the shapes to a lower energy level, creating
a pocket with a different set of laws from the surrounding space.
5. LANDSCAPE

27. The quantum multiverse creates a new universe when a diversion in events
occurs, as in the many-worlds interpretation of quantum mechanics.
6. QUANTUM

28. The holographic multiverse is derived from the theory that the surface area of
a space can simulate the volume of the region.
7. HOLOGRAPHIC

29. The simulated multiverse exists on complex computer systems that simulate
entire universes.
8. SIMULATED

30. The ultimate multiverse contains every mathematically possible universe under
different laws of physics.
9. ULTIMATE

31. OTHER THEORIES

32. In several theories there is a series of infinite, self-sustaining cycles (for
example: an eternity of Big Bang-Big crunches).
CYCLIC THEORIES

33. A multiverse of a somewhat different kind has been envisaged within string
theory and its higher-dimensional extension, M-theory. These theories require
the presence of 10 or 11 spacetime dimensions respectively. The extra 6 or 7
dimensions may either be compactified on a very small scale, or our universe
may simply be localized on a dynamical (3+1)-dimensional object, a D-brane.
This opens up the possibility that there are other branes which could support
"other universes". This is unlike the universes in the "quantum multiverse",
but both concepts can operate at the same time.
Some scenarios postulate that our big bang was created, along with our
universe, by the collision of two branes.
M-THEORY

35. A black-hole cosmology is a cosmological model in which the observable
universe is the interior of a black hole existing as one of possibly many inside
a larger universe.
This includes the theory of white holes of which are on the opposite side of
space time. While a black hole sucks everything in including light, a white hole
releases matter and light, hence the name "white hole".
BLACK-HOLE COSMOLOGY

36. The concept of other universes has been proposed to explain how
our own universe appears to be fine-tuned for conscious life as we
experience it.
If there were a large (possibly infinite) number of universes, each with
possibly different physical laws (or different fundamental physical constants),
some of these universes, even if very few, would have the combination of
laws and fundamental parameters that are suitable for the development
of matter, astronomical structures, elemental diversity, stars, and planets that
can exist long enough for life to emerge and evolve. The weak anthropic
principle could then be applied to conclude that we (as conscious beings)
would only exist in one of those few universes that happened to be finely
tuned, permitting the existence of life with developed consciousness.
ANTHROPIC PRINCIPLE

37. Thus, while the probability might be extremely small that any particular
universe would have the requisite conditions for life (as we understand life) to
emerge and evolve, this does not require intelligent design as an explanation
for the conditions in the Universe that promote our existence in it.

39. Around 2010, scientists such as Stephen M. Feeney analyzed Wilkinson
Microwave Anisotropy Probe (WMAP) data and claimed to find preliminary
evidence suggesting that our universe collided with other (parallel) universes
in the distant past
However, a more thorough analysis of data from the WMAP and from
the Planck satellite, which has a resolution 3 times higher than WMAP, failed
to find any statistically significant evidence of such a bubble universe
collision. In addition, there is no evidence of any gravitational pull of other
universes on ours
SEARCH FOR EVIDENCE

40. Overall no evidence is found to support the existence of a multiverse.
SEARCH FOR EVIDENCE

41. Multiverse has been portrayed in other media as well. Like in games, tv series,
and movies.
MUTIVERSE IN MEDIA

42. Movies like Jet-Li’s “The One” as an Multiverse Police Officer whose task is
to balance each universe.
MUTIVERSE IN MEDIA

43. Games like Spider-Man Shattered Dimensions, tells the story of a crisis that
each Spider-Man in a universe is being killed so all Spider-Men in each
universe helps each other to solve the crisis.
MUTIVERSE IN MEDIA

44. And in Comics like Justice Leageu which
features lot of parallel countreparts of the
characters which was even adapted into an
animated movie titled: Justice Leageu Crisi
of Two Earth.
MUTIVERSE IN MEDIA

45. And finally in a TV series titled ‘Fringe’ tells a story of a boy later a young
adult living(after being kidnapped by his fathers counterpart ) on our world
taking over his dead counterpart as a detective alongside his counterpart’s
father. The show lasted 5 seasons.
