For what it is
worth, my cloud cosmology model is completely capable of addressing the two
core issues bedeviling present day cosmology based on the so called standard
theory. Dark energy is easy and merely
addresses content of the universe largely below our detection threshold which
sadly describes most of it.
Gravitation is
much more interesting and must await detailed simulation before we correctly
isolate the effect. Yet we have options
not least driven by imperfect tetrahedral packing. It will be exciting to investigate. I also think that we have come up short in
our empirical work here and can do much more there.
While we are
waiting, this work is now beginning to address the real gaps in our perception
of space and time.
New
groundbreaking research may expose new aspects of the universe

No one knows for sure, but it is not at all unlikely
that the universe is constructed in a very different way than the usual
theories and models of today predict. The most widely used model today cannot
explain everything in the universe, and therefore there is a need to explore
the parts of nature which the model cannot explain.
This research field is called new physics, and it
turns our understanding of the universe upside down. New research now makes the
search for new physics easier.
"New physics is about searching for unknown
physical phenomena not known from the current perception of the universe. Such
phenomena are inherently very difficult to detect," explains PhD student
Matin Mojaza from CP3-Origins.
Together with colleagues Stanley J. Brodsky from
Stanford University in the U.S. and Xing-Gang Wu from Chongqing University in
China, Mojaza has now succeeding in creating a new method that can make it
easier to search for new physics in the universe.
The method is a so called scale-setting procedure,
and it fills out some empty, but very important, holes in the theories, models
and simulations, which form the basis for all particle physics today.
"With this method we can eliminate much of the
uncertainty in theories and models of today," says Matin Mojaza.
Many theories and models in particle physics today
has the problem that they, together with their predictions, provide some
parameters that scientists do not know how to set.
"Physicists do not know what values they should
give these parameters. For example, when we study the Standard Model and see
these unknown parameters, we cannot know whether they should be interpreted as
conditions that support or oppose to the Standard Model - this makes it quite
difficult to study the Standard Model accurately enough to investigate its
value", explains Matin Mojaza.
With the new approach researchers can now completely
clean their models for the unknown parameters and thus become better at
assessing whether a theory or a model holds water.
The standard model has for the last app. 50 years
been the prevailing theory of how the universe is constructed. According to
this theory, 16 (17 if we include the Higgs particle) subatomic particles form
the basis for everything in the universe. But the Standard Model is starting
to fall short, so it is now necessary to look for new physics in the universe.
One of the Standard Model's major problems is that it
cannot explain gravity, and another is that it cannot explain the
existence of dark matter, believed to make up app. 25 percent of all matter
in the universe. In addition, the properties of the newly discovered Higgs
particle, as described in the standard model, is incompatible with a stable
universe.
"A part of the Standard Model is the theory of
quantum chromodynamics, and this is one of the first things, we want to review
with our new method, so that we can clean it from the uncertainties,"
explains Matin Mojaza.
The theory of quantum chromodynamics predicts how
quarks (such as protons and neutrons) and gluons (particles that keeps quarks
in place inside the protons and neutrons) interact.
Matin and his Chinese and American colleagues now
estimate that there may be a basis for reviewing many scientific calculations
to clean the results from uncertainties and thus obtain a more reliable picture
of whether the results support or contradict current models and theories.
"Maybe we find new indications of new physics,
which we would not have exposed if we had not had this new method", says
Matin Mojaza.
He believes that the Standard Model needs to be
extended so that it can explain the Higgs particle, dark matter and gravity.
One possibility in this regard is to examine the so-called technicolor theory,
and another is the theory of supersymmetry.
According to the supersymmetry theory, each
particle has a partner somewhere in the universe - these have not yet been
found though. According to the technicolor theory there is a special
techni-force that binds so-called techni-quarks, which can form other particles
- perhaps this is how the Higgs particle is formed. This could explain the
problems with the current model of the Higgs particle.
Also Rolf-Dieter Heuer, director of CERN in
Switzerland, where the famous 27 km long particle accelerator, the LHC, is
situated, believes that the search for new physics is important. According to
him, the Standard Model cannot be the ultimate theory, and it is only capable
of describing about 35 percent of the universe. Like CP3-Origins, also CERN has
put focus on weeding out old theories and search for new physics - this
happening in 2015, when the accelerator starts up again.
CP3-Origins is a center at University of Southern
Denmark, researching in the physics beyond the Standard Model. The center
focuses on topics such as dark matter, the formation of matter in the universe,
and the mystery of what the Higgs particle might consist of.
