Scientists have proposed a new £12 billion supercollider –

Ever since the quantum revolution rocked the physical world, scientists have been clamoring to answer the universe’s biggest and most perplexing questions. One such question relates to what the universe actually consists of, as recent studies have suggested that as much as 95% of matter consists of theorized and mysterious dark matter and energy, with matter we know and understand making up only 5% of the universe. With recent developments (such as the discovery of the Higgs particle in 2012), scientists are trying to crack open the universe like a walnut by using a proposed and much larger supercollider.
According to BBC News, this new collider would be about three times the size of the current one funded by CERN, the Large Hadron Collider (LHC), and assuming the proposal gets the green light, it would cost about £12 billion to build. Funding would come from countries that are part of CERN, also known as the European Organization for Nuclear Research, and this new machine would be called the Future Circular Collider (FCC).
The FCC plans to be built again in Central Europe, near the LHC, covering a total length of 56.5 miles through Switzerland and France. The goal is to use the machine to discover dark matter and energy to create a more complete theory of how the universe works.
