Larger supercollider demanded by researchers at the world’s biggest particle accelerator to find missing 95% of Universe

Researchers at Switzerland based world’s biggest particle accelerator have put forth a proposal for a new, comparatively larger, supercollider. Its aim understandably is to discover new particles that would revolutionize physics and lead to a more thorough understanding of how the Universe functions. If built, it will be three times larger than Large Hadron Collider (the current giant machine).
Price tag of this proposed supercollider is £17bn and has raised some eyebrows, with one particular critic labelling the expenditure as “reckless”. That astronomical sum – which is only the initial construction cost – would be pooled by member nations of the European Organization for Nuclear Research (Cern) including the UK, and quite a few experts have questioned whether it makes economic sense.
The single most important achievement of the Large Hadron Collider (LHC) was the detection of a new particle called the Higgs Boson in 2012. But since then its ambitious aim to track down two holy grails of physics – dark energy and dark matter – have proved elusive and many researchers firmly believe there are cheaper options.
The new proposed machine has been named the Future Circular Collider (FCC). Cern’s director general (Prof. Fabiola Gianotti) told BBC News that, if built, it will be a “beautiful machine”. “It is a tool that will allow humanity to make enormous steps forwards in answering questions in fundamental physics about our knowledge of the Universe. And to do that we need a more powerful instrument to address these questions,” she stated.
FCC is the successor of LHC
The LHC’s detection of the Higgs Boson particle over 10 years ago was ground-breaking. The presence of a building block that gives all other particles in the Universe their form was predicted way back in 1964 by the British physicist, Peter Higgs, but was only discovered in 2012 at the LHC. It was the final piece of the jigsaw of the Standard Model (current theory of sub-atomic physics).
The proposal is for the larger FCC (compared to LHC) to be built in two stages. The first will start operating in the mid-2040s and will collide electrons together. It is expected the increased energy will yield large numbers of Higgs particles for scientists to study in detail. The second phase will start in the 2070s and need more powerful magnets, so advanced that they are yet to been invented. Instead of electrons, heavier protons will be utilized in the hunt for brand new particles.
Circumference of the FCC will be approximately three that of the circumference of the LHC, a mind-boggling 91km and twice as deep. It needs to be deeper to prevent the far stronger radiation produced by the higher energies from reaching the surface.
So why do they require an even larger hadron collider?
It is because the LHC, which was built at a cost of £3.75 billion, despite being in operation for 16 years has failed to find particles that will help to explain 95% of the cosmos. Scientists are still hunting for two big unknowns – a force called dark energy which behaves like the opposite to gravity, and drives substances in the Universe such as galaxies apart. The other is dark matter, which is undetectable but its presence is felt through gravity.
