天使粒子 Angel Partical 近日引起了人们的热烈关注,这也许是物理学里的一个重大新发现。
打破了以往人们观念中的 物资/反物质, 粒子/反粒子 的定律。
科学是发展的, 物理学当然亦然。电子(荷负)- 正电子, 质子 - 反质子 等等都是成对儿存在的。
那么 为何 天使粒子 是独立超然的呢? 果真如此吗?
物理学的发展必将解释和阐明真谛。恳请物理学界学人赐教。
动物界有雌雄同体, 植物界亦然;
人类最初胚胎早期是无性或男女同体的,绝大多数后来分化发育成男性或女性,
极个别的,一生都是两性体,或曰 阴阳人。
天使粒子 是否这样一个一定条件下一定时段里存在的两性的结合体呢?愚下冒昧猜度~:)
正如 A Particle That’s Its Own Anti-Particle 所说?

A Particle That’s Its Own Anti-Particle
Whooooaaaa.
SOMEWHERE OUT THERE IN THE big wide universe, every fundamental particle has a twin with an opposite charge, its antiparticle. An electron has a positron, a proton has an antiproton, and so forth. Under the right conditions, these particle pairs can destroy each other. But 80 years ago the physicist Ettore Majorana predicted that certain types of particles, in the fermion class, could be their own antiparticles—a sort of high physics yin/yang pairing.
Now a team of scientists at UCLA and Stanford have for the first time observed these special particles, known as Majorana fermions.
Using “exotic materials,” according to Science Daily, the scientists created an experiment in which particles would moving along a one-dimensional path in one direction. Using a magnet, they were able to make the particles change direction. At certain points in that cycle, when the particles switched directions, these Majorana particle emerged.
The scientists are calling the particles they coaxed out “Angel particles,” after the Dan Brown novel Angels & Demons, which features a bomb of matter and antimatter.
These lab-grown particles could contribute to advances in quantum computing, but they were created under very specific conditions. “It’s very unlikely that they occur out in the universe, although who are we to say?” one scientist who’s studying these particles said. But scientists still think it’s possible that some neutrinos could also be their own antiparticles, which would mean that these strange phenomena of physics, the Majorana particles, were everywhere.
Ettore Majoranahypothesised the existence of Majorana fermions in 1937
Because particles and antiparticles have opposite conserved charges,
Majorana fermions have zero charge.
