Antimatter is treated like an exotic substance, fraught with danger, which can only be harnessed in the future to send star ships to warp speed. However, this isn't true. We use antimatter right now, and we use it in hospitals. Learn how PET scans use positrons to help you.

And now, some 80 years later, a team of physicists have a plan to carry out the experiment in real life.
