La — Materia Oscura

Building ultra-sensitive detectors deep underground (to shield them from cosmic rays) in hopes of capturing the rare moment a dark matter particle collisions with normal matter.

In the 1970s, astronomer Vera Rubin discovered that the outer edges of spiral galaxies rotate just as fast as the centers. According to standard physics, the outer edges should fly apart unless held together by a massive, unseen halo of matter. La materia oscura

Massive concentrations of dark matter warp the fabric of space-time. Light traveling from distant galaxies bends around this invisible mass on its way to Earth, creating visual distortions that allow scientists to map where the dark matter resides.

Using space telescopes like Fermi to look for gamma rays or antimatter produced when dark matter particles annihilate each other in deep space. Heavy, slow-moving particles that only interact via gravity

Heavy, slow-moving particles that only interact via gravity and the weak nuclear force.
