WIMPs, or Weakly Interacting Massive Particles, are hypothetical particles that are a leading candidate for dark matter. They are thought to interact through the weak nuclear force and gravity, making them difficult to detect. Scientists believe that WIMPs could help explain the missing mass in the universe, which is not accounted for by visible matter like stars and galaxies. Research into WIMPs is ongoing, with various experiments designed to detect these elusive particles. If discovered, WIMPs could provide crucial insights into the fundamental nature of the universe and the composition of dark matter, which makes up about 27% of the universe's total mass-energy content.
