Theories about other dimensions

I search many things in outer space and i saw many things that

i never saw:

The inflationary multiverse is composed of various pockets in

which inflation fields collapse and form new universes. 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".

The multiverse (or meta-universe) is the hypothetical set of

finite and infinite possible , including the universe in which

we live. Together, these universes comprise everything that

exists: the entirety of , , , , and the and that describe them.

The various universes within the multiverse are called

"parallel universes", "other universes" or "alternate

universes."

The American philosopher and psychologist coined the term

multiverse in 1895, but in a different context.

In Dublin in 1952 gave a lecture in which at on point he

jocularly warned his audience that what he was about to say

might "seem lunatic". It was that, when his Nobel equations

seem to be describing several different histories, they are

"not alternatives but all really happen simultaneously". This

is the earliest known reference to the multiverse.

The structure of the multiverse, the nature of each universe

within it, and the relationships among these universes depend

upon the specific multiverse hypothesis being considered.

Multiple universes have been hypothesized in , , , , , , and ,

particularly in and . 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".

The physics community continues to debate the multiverse .

Prominent physicists disagree about whether the multiverse

exists.

Some physicists say the multiverse is not a legitimate topic of

scientific inquiry. Concerns have been raised about whether

attempts to exempt the multiverse from experimental

verification could erode public confidence in science and

ultimately damage the study of fundamental physics. Some have

argued that the multiverse is a philosophical rather than a

because it cannot be . The ability to disprove a theory by

means of scientific experiment has always been part of the
