Will Antimatter Obey Gravity’s Pull?

What goes up must always come down, right? Well, the European Laboratory for Particle Physics (CERN) wants to test if that principle applies to antimatter.

Antimatter, most simply speaking, is a mirror image of matter. The concept behind it is that the particles that make up matter have an opposite counterpart, antiparticles. For example, if you consider that electrons are negatively charged, an antielectron would be positively charged.

This sounds like science fiction, but as NASA says, it is “real stuff.” In past experiments, CERN’s particle accelerator has created antiprotons, positrons and even antihydrogen. Properly harnessed, antimatter could be used for applications ranging from rocketry to medicine, NASA added. But we’ll need to figure out its nature first.
