AdvertisementInterstellar travel is only something humanity has achieved in science fiction — like Star Trek's USS Enterprise, which used antimatter engines to travel across star systems. "Annihilation of antimatter and matter converts mass directly into energy," Weed, cofounder and CEO of Positron Dynamics, a company working to develop an antimatter propulsion system, told Business Insider. Space travel at record speedProxima's star system, shown here, could be reached in just five years with antimatter-powered technology. For example, let's take a trip to our nearest star system, Proxima, about 4.2 light years away. And since the '80s, there's been talk of thermal antimatter engines, which would use antimatter to heat liquid, gas, or plasma to provide thrust.

Antimatter is the enigmatic twin of ordinary matter, possessing the same mass but with an opposite electrical charge. Under current theory, the Big Bang explosion that initiated the universe should have produced equal amounts of matter and antimatter. However, antimatter can be synthesized under controlled conditions, as in the ALPHA experiment, which used antihydrogen created at CERN. "The nearly complete absence of naturally occurring antimatter is one of the great questions facing physics," Wurtele said. "No matter how pretty the theory, physics is an experimental science," Fajans said.

Manhattan Project: After a harrowing escape from Nazi-occupied Denmark in 1943, Bohr began consulting on the Manhattan Project. Manhattan Project: Between 1943 and 1944, Muller was a civilian advisor for the Manhattan Project, consulting on experiments studying the effects of radiation. Maria Goeppert Mayer, Nobel Prize in Physics, 1963Maria Goeppert Mayer worked on the Manhattan Project and later won the Nobel Prize in physics. Manhattan Project: Working as an assistant to his father, Niels Bohr, Aage Bohr proved instrumental in interpreting for some members of the Manhattan Project. Manhattan Project: At 18, Glauber was still a student at Harvard when he became one of the youngest scientists to join the Manhattan Project.

Penning traps contain ultra-thin foils, about 1.5 micrometers thick, that further slow down and capture antiprotons sent from the ELENA ring. Before ELENA was installed in 2018 to help slow down antiprotons even more, CERN caught less than 1% of antiprotons it produced. Now, it captures up to 70%. Thin foil strips, shown in blue here, are placed at the end of a Penning trap to help slow and trap antimatter particles. CERNSources: CERN, Sameed Muhammed
