Physics

There is really an anti-copy of Chan Dai Man, both copies are real/true. Both the particle and the anti-particle are real.

The existence of ant-particles do not mean that anti-atoms or anti-molecules also exist.

In fact, physicsts have spent decades trying to "create" anti-hydrogen atmos from the particles anti-proton and positron. But such ant-hydrogen atoms are only in existence for a short period of time (no longer than 1 micro second).

Recently, physicists have suceeded in creating ant-helium atoms. Again, these atoms disintegrate within nano seconds.

Whether there is a copy of Mr. Chan Dai Man would exist is still too remote.

係物理學上有反粒子,
但唔代表正粒子永遠伴隨住反粒子,
所以有由正粒子結組成ge陳大明,
唔一定會有由反物質組成ge陳大明,
反粒子係因為同我地見開ge粒子唔同,
先至會叫做「反」,
不過係physic上黎講,
佢地都係實實在在ge,
都係「真」ge
