Moving Dimensions Theory Accounts for Inflation & Dark Energy: MDT Also Unifies DR & QM & It Accounts for Time's Arrow |
http://physicsmathforums.com
Moving Dimensions Theory's central postulate is that:
The fourth dimension is expanding relative to the three spatial
dimensions.
A more specific verison is: the fourth dimension is expanding relative
to the three spatial dimensions, at a rate of c in quatized units of
the planck length.
MDT's postualte accounts for both Inflation & Dark Energy:
Simply put, the expansion of the fourth dimension relative to the three
spatial dimensions has been slowing down. Thus, the early universe was
casually connected, as light traveled faster, explaining Inflation.
MDT stipulates that light is matter surfing the fourth expanding
dimension.
Also, it appears that the universe's expansion is accelerating. This
is because the expansion of the fourth dimension is slowing relative to
the three spatial dimensions. Thus light takes longer to travel from
type la supernovas, and hence it appears that type la supernovas are
further away.
So it is that MDT explains both Inflation and Dark Enegry:
1. The fourth dimension is expanding relative to the three spatial
dimensions.
2. The rate of the expansion of the fourth dimension is slowing.
Cosmic inflation:
http://en.wikipedia.org/wiki/Cosmic_inflation
Cosmic inflation is the idea, first proposed by Alan Guth in 1981, that
the nascent universe passed through a phase of exponential expansion
(the inflationary epoch) that was driven by a negative pressure vacuum
energy density.
This expansion is similar to a de Sitter universe with a positive
cosmological constant. As a direct consequence of this expansion, all
of the observable universe originated in a small causally-connected
region. Quantum fluctuations in this microscopic region, magnified to
cosmic size, then became the seeds for the growth of structure in the
universe (see galaxy formation and evolution). The particle responsible
for inflation is generally called the inflaton.
The name of the theory was a semi-humorous reference to the economic
inflation in the United States in the late 1970s.
Dark Energy:
http://en.wikipedia.org/wiki/Dark_energy
During the late 1990s, observations of type Ia supernovae ("one-A") by
the Supernova Cosmology Project and the High-z Supernova Search Team
suggested that the expansion of the universe is accelerating.[4][5]
Since then, these observations have been corroborated by several
independent sources. Measurements of the cosmic microwave background,
gravitational lensing, and the large scale structure of the cosmos as
well as improved measurements of supernovae have been consistent with
the Lambda-CDM model.[6]
Unsolved problems in physics: Why is the expansion of the universe
accelerating, as we have observed? Is our understanding of redshift
complete? If it is, then what is the nature of the dark energy driving
this acceleration?The type Ia supernovae provide the most direct
evidence for dark energy. Measuring the scale factor at the time that
light was emitted from an object is accomplished easily by measuring
the redshift of the receding object. Finding the distance to an object
is a more difficult problem, however. It is necessary to find standard
candles: objects for which the actual brightness, what astronomers call
the absolute magnitude, is known, so that it is possible to relate the
observed brightness, or apparent magnitude, to the distance. Without
standard candles, it is impossible to measure the redshift-distance
relation of Hubble's law. Type Ia supernovae are the best known
standard candles for cosmological observation because they are very
bright and thus visible across billions of light years. The consistency
in absolute magnitude for type Ia supernovae is explained by the
favored model of an old white dwarf star which gains mass from a
companion star and grows until it reaches the precisely defined
Chandrasekhar limit. At this mass, the white dwarf is unstable to
thermonuclear runaway and explodes as a type Ia supernova with a
characteristic brightness. The observed brightness of the supernovae
are plotted against their redshifts, and this is used to measure the
expansion history of the universe. These observations indicate that the
expansion of the universe is not decelerating, which would be expected
for a matter-dominated universe, but rather is mysteriously
accelerating. These observations are explained by postulating a kind of
energy with negative pressure (see equation of state (cosmology) for a
mathematical explanation): dark energy.
