How do astrophysicists study astroparticles?

Astrophysicists can simulate the extreme conditions particles experience in the universe, such as traveling at nearly the speed of light and enduring temperatures of millions or even billions of degrees, because everything in the universe is the same, including atoms, waves, and the laws of physics.

The Large Hadron Collider and CERN are the most well-known facilities.

However, there are telescopes and particle detectors on Earth as well, like IceCube and LIGO.

Astrophysicists study astroparticles using a combination of observational techniques, theoretical models, and experimental methods. They observe cosmic rays, neutrinos, and high-energy photons using ground-based detectors, telescopes, and satellites. They also analyze data from particle colliders and conduct simulations to understand the behavior and interactions of astroparticles in various astrophysical environments.
