CERN isn’t done just yet.

After discovering the smallest particle that could ever exist, the team at CERN is now considering scaling up, with an even larger brand new particle collider. The Geneva based team discovered what they believe is the Higgs Boson, also known as the “God Particle” this summer but they aren’t completely satisfied with their findings. The proposal features a new underground accelerator with a circumference of 50 miles, three times the size of the current one under Geneva.

The Large Hadron Collider 2 will be used to solve a new batch of mysteries of the universe, such as how gravity interacts on a molecular level. The new collider is unlikely to be built before 2025, but the CERN team is eager to get a head start on developing and planning the entire project. The estimated cost of the entire project is in the $4.6 billion range.

Gravity is one key area which the team may work on with a new collider. It is still not clear how gravity can operate both at the particle level, and at the level of planets, stars and solar systems. The team said they were worried that scientific discovery would be stalled until a new collider was developed, citing how Peter Higgs, who first proposed his Higgs Boson theory in 1964, had to wait 58 years to see his ideas validated. The first collider was suggested in 1983, but work did not start on building it until 1998.
