反物质, 反粒子物质
(physics) matter consisting of elementary particles that are the antiparticles of those of regular matter
- Antimatter is composed of antiparticles, which have the same mass as their corresponding particles but opposite electric charge.
反物质由反粒子组成，反粒子与相应粒子质量相同但电荷相反。
- When matter and antimatter particles collide, they annihilate each other, releasing energy in the form of gamma rays.
当物质和反物质粒子碰撞时，它们会相互湮灭，以伽马射线的形式释放能量。
- Antimatter is rare in the universe, but small amounts of it can be produced in high-energy particle collisions.
反物质在宇宙中很罕见，但可以在高能粒子碰撞中产生少量。
- Scientists study antimatter to better understand the fundamental laws of physics and the origins of the universe.
科学家研究反物质以更好地理解物理学的基本定律和宇宙的起源。
- Antimatter propulsion is a theoretical concept that could potentially enable spacecraft to travel at near-light speeds in the future.
反物质推进是一种理论概念，未来可能使航天器以接近光速的速度飞行。
