Big Bang theory could be debunked by Large Hadron Collider

Scientists at Cern could prove the controversial theory of ‘rainbow gravity’ which suggests that the universe stretches back into time infinitely, with no Big Bang

(Daily Telegraph- UK) The detection of miniature black holes by the Large Hadron Collider could prove the existence of parallel universes and show that the Big Bang did not happen, scientists believe.

The particle accelerator, which will be restarted this week, has already found the Higgs boson – the God Particle – which is thought to give mass to other particles.

Now scientists at Cern in Switzerland believe they might find miniature black holes which would reveal the existence of a parallel universe.

And if the holes are found at a certain energy, it could prove the controversial theory of ‘rainbow gravity’ which suggests that the universe stretches back into time infinitely with no singular point where it started, and no Big Bang.

The theory was postulated to reconcile Einstein’s theory of general relativity – which deals with very large objects, and quantum mechanics – which looks at the tiniest building blocks of the universe. It takes its name from a suggestion that gravity's effect on the cosmos is felt differently by varying wavelengths of light.

The huge amounts of energy needed to make ‘rainbow gravity’ would mean that the early universe was very different. One result would be that if you retrace time backward, the universe gets denser, approaching an infinite density but never quite reaching it.

The effect of rainbow gravity is small for objects like the Earth but it is significant and measurable for black holes. It could be detected by the Large Hadron Collider if it picks up or creates black holes within the accelerator.

“We have calculated the energy at which we expect to detect these mini black holes in gravity's rainbow [a new theory]. If we do detect mini black holes at this energy, then we will know that both gravity's rainbow and extra dimensions are correct, Dr Mir Faizal told Phys.org.


The second run of the LHC will begin this week and the beams are expected to go full circle on Wednesday for the first time since the 27km accelerator was shut down in early 2013 for an upgrade.

When it is fired up it will smash protons together at nearly double the energy that was used to find the Higgs boson.

Rolf Heuer, Director General of CERN, said the switch-on would create ‘a new era for physics’ which could also shed light on dark matter, dark energy and super-symmetry.

“I want to see the first light in the dark universe. If that happens, then nature is kind to me.”

Scientists believe they could find the first proof of alternative realities that exist outside out own universe.

It is even possible that gravity from our own universe may ‘leak’ into this parallel universe, scientists at the LHC say.

“Just as many parallel sheets of paper, which are two dimensional objects [breadth and length] can exist in a third dimension [height], parallel universes can also exist in higher dimensions,” added Dr Faizal,

“We predict that gravity can leak into extra dimensions, and if it does, then miniature black holes can be produced at the LHC.

“Normally, when people think of the multiverse, they think of the many-worlds interpretation of quantum mechanics, where every possibility is actualised.

"This cannot be tested and so it is philosophy and not science.

“This is not what we mean by parallel universes. What we mean is real universes in extra dimensions.


“As gravity can flow out of our universe into the extra dimensions, such a model can be tested by the detection of mini black holes at the LHC.”

The Large Hadron Collider (LHC) has undergone important upgrades and repairs over the past two years since the first shutdown.

The particle collider boasts new magnets, superior cryogenics, higher voltage and higher energy beams that will allow the machine to run at nearly double the collision energy of the first run.

The first circulating beams of protons in the LHC are planned for the week beginning 23 March, and by late May to early June the LHC aims to be running at 13 TeV.

Frances Saunders, president of the IOP, said, “This has been a massive effort by all the scientists and engineers at CERN to upgrade the LHC and its detectors and get it ready to operate at almost double the collision energies of the first run.

“As well as allowing greater study of the Higgs boson there is much anticipation amongst the physics community as to what else may be found at these higher energies, testing our theories and understanding of concepts such as supersymmetry and potentially giving greater insight into the 95 per cent of the universe that is composed of dark matter and dark energy.”

Nasa's Solar Dynamics Observatory, or SDO, captured this solar image which clearly shows two dark patches, known as coronal holes. The larger coronal hole of the two, near the southern pole, covers an estimated 6 to 8 percent of the total solar surface. While that may not sound significant, it is one of the largest polar holes scientists have observed in decades.

JUST DISCOVERED IN AUSTRALIA: THE LARGEST ASTEROID IMPACT EVER
The new discovery in Australia dwarfs Meteor Crater in Arizona, one of the best preserved meteorite craters in the world. The crater in Australia is nearly 250 times larger than Meteor Crater.

A long time ago, a huge meteorite entered the earth's atmosphere in a screaming fireball. In its last violent moments, it split into two massive pieces, each at least 6 miles across, and slammed into the earth, creating twin impact craters spanning nearly 250 miles of the Australian countryside.

The craters have been covered over by natural processes since the impact, but researchers found evidence recently while

for a potential geothermal energy project. They found layers of quartz that had been shocked, a technical term for quickly deforming during an impact. When they looked closer, and did some additional tests on the area, the researchers found that there was also evidence from much deeper in the earth's crust.

"There are two huge deep domes in the crust, formed by the Earth's crust rebounding after the huge impacts, and bringing up rock from the mantle below," lead researcher Andrew Glikson
