What Would An Antimatter Universe Look Like? - Forbes
2017年11月18日 · Our antimatter universe would simply be filled with traces of anti-hydrogen and anti-helium, and nothing would ever look up at the cosmic sky.
What Antimatter Is and Where to Find It - ThoughtCo
2019年2月6日 · What Does Antimatter Look Like? When you see antimatter depicted in science fiction movies, it's usually some weird glowing gas in a special containment unit. Real antimatter looks just like regular matter.
What does antimatter look like? - Physics Stack Exchange
2016年11月26日 · Antimatter looks just like matter. Experimentally, there is no difference between the spectral lines of antihydrogen and of ordinary hydrogen. Same emission spectrum. The photon is its own antiparticle. It interacts in the same way with matter as with antimatter.
Antimatter - Wikipedia
In modern physics, antimatter is defined as matter composed of the antiparticles (or "partners") of the corresponding particles in "ordinary" matter, and can be thought of as matter with reversed charge, parity, and time, known as CPT reversal.
Seven Things to Know About Antimatter and Why it Matters
2024年2月7日 · “An antiproton looks like a proton, but it has a negative electrical charge. An anti-electron, sometimes called a positron, has a positive electric charge. So, antimatter is simply this other particle that exists with the opposite charge but otherwise looks the same — same mass and same way of interacting.”

DOE Explains...Antimatter - Department of Energy
Scientists haven’t seen anti-matter regions in our universe, but they have created copious amounts of antiparticles in particle accelerators and even created anti-elements and anti-atoms. We also know about antimatter from the anti-particles that cosmic ray collisions create.
Antimatter explained | BBC Sky at Night Magazine
Antimatter sounds like science fiction: a material that looks like ordinary matter, but would unleash as much energy as an atomic bomb if even a speck of it came into contact with anything around us. Chances are that you first encountered the concept of antimatter in Star Trek, where it’s used to propel spaceships.
