Will the Large Hadron Collider find a parallel universe? Particle smasher could become a gateway to alternate realities, say scientists
- Scientists predict gravity can sometimes leak into an extra dimension
- If this happens, it will create tiny black holes that can be found by LHC
- LHC has failed to find any, but study claims it has gravity model wrong
- Theory says it should be looking for black holes at higher energy levels
- The LHC is due to be turned back on next week with double the energy
It has found the 'God particle', and could soon reveal a mysterious force known as 'dark matter'.
But
when it turns on next week, some scientists are betting the Large
Hadron Collider will detect something just as exciting; a parallel
universe.
This
is according to a new study that claims miniature black holes - a key
sign of a 'multiverse' - could be detected in Cern's LHC in Geneva.

universe
'Just
as many parallel sheets of paper, which are two dimensional objects
(breath and length) can exist in a third dimension (height), parallel
universes can also exist in higher dimensions' Mir Faizal from the
University of Waterloo told Dailymail.com.
'We
predict that gravity can leak into extra dimensions, and if it does,
then miniature black holes can be produced at the LHC.'
Professor
Faizal and his team have calculated the energy at which they expect to
detect these mini black holes in gravity's rainbow, according to a
report by Lisa Zyga at Phys.org.
'If
we do detect mini black holes at this energy, then we will know that
both gravity's rainbow and extra dimensions are correct,' added
Professor Faizal.
When
it's activated, the energy with which the LHC smashes particles
together will be twice what it was during the time when it made the
discovery of the Higgs boson.
Billions
of particles flying off from each LHC collision are tracked at Cern
detectors to establish when and how they come together and what shapes
they take.
The Cern theoreticians say this could give clear signs of dimensions beyond length, breadth, depth and time.
At such high energy gravity many be even tracked disappearing into them.
Parallel
universes can exist within these dimensions, the thinking goes, but
only gravity can leave our universe into these extra dimensions.
If
extra dimensions do exist, the study suggests that they would lower the
energy required to produce black holes which the LHC could pick.
Professor
Faizal suggests the reason these black holes have yet to be detected is
because our current model of gravity gets modified at very high
energies.
According
to Phys.org, in the latest study, the new theory of gravity's rainbow
has been used to account for why the LHC has not yet found tiny black
holes.
The new theory of gravity's rainbow
has been used to account for why the LHC has not yet found tiny black
holes. Einstein's theory of relativity states that gravity is caused by
space and time curving. Gravity's rainbow says that space and time curve
differently for particles of different energy
Einstein's theory of relativity states that gravity is caused by space and time curving.
Gravity's rainbow says that space and time curve differently for particles of different energy.
So, gravity's rainbow suggests that gravity's effect on the cosmos causes different wavelengths of light to behave differently.
This means that particles with different energies will move in space-times and gravitational fields differently.
Using
gravity's rainbow, the scientists found that more energy is required to
detect mini black holes at the LHC than previously thought.
So far, the LHC has searched for mini black holes at energy levels below 5.3 TeV.
But
the latest study says this is too low. Instead, the model predicts that
black holes may form at energy levels of at least 9.5 TeV in six
dimensions and 11.9 TeV in 10 dimensions.
If
mini black holes are detected at the LHC at the predicted energies, not
only will it prove the existence of extra dimensions and by extension
parallel universes, said Ahmed Farag Ali from Florida State University.
'If
black holes are not detected at the predicted energy levels, this would
mean one of three possibilities,' Mohammed Khalil explained to
Phys.Org
'One,
extra dimensions do not exist. Two, they exist, but they are smaller
than expected. Or three, the parameters of gravity's rainbow need to be
modified.'
