America’s Particle Physics Plan Spans the Globe — and the Cosmos
- Hitoshi Murayama, the Berkeley professor and particle physicist, speaks on the top five projects recommended over the next 10 years of US investment, which focus on phenomena ranging from subatomic smash-ups to cosmic inflation.
- Projects recommended for US funding are not new, and not all are based in the US itself, with recommendations stretching to include South Dakota, Japan and Chile.
- 85% of all of the matter in the universe is thought to exist in an invisible form that has yet been undetectable but is in the process of being investigated.
- The Big Bang is thought to have created equal amounts of matter and antimatter, both of which would annihilate each other; this process is being studied by examining neutrinos and the way they behave.
- The IceCube Neutrino Observatory in Antartica is currently undergoing a dramatic expansion to help observe the universe in different ways.
- The P5 endorsed a longer-term effort to develop an advanced particle accelerator machine that would produce collisions between subatomic particles known as muons, which would increase chances of finding new frontiers in physics.
- The recommendations are under consideration by the US Department of Energy and the National Science Foundation.
- The cost of pursuing the offshore Higgs factory is certain to amount to billions of dollars.
- Uncertainty around prioritisation is compounded by worries that a U.S. Air Force fleet of cargo airplanes used for ice research is due for retirement, with no immediate replacement.
- Sabine Hossenfelder has produced a video on the matter arguing that the list of multimillion dollar physics experiments should not be followed.
