The observed imbalance between matter and antimatter is a puzzle yet to be explained. 在物质和反物质之间观察到的不平衡仍然是一个还没有解释的难题。
In coining the term" antimatter," physicists in fact redefined the meaning of the word" matter. 在敲定术语“反物质”中,物理学家事实上重新定义了粒子物理学的现代理论和宇宙的进化提议“物质”那个字的含义。
According to the standard theories of physics, the antimatter universe should look identical to our own. 依照物理学的标准理论,反物质宇宙应该看起来与我们自己的宇宙相同。
antimatter
[ noun ] matter consisting of elementary particles that are the antiparticles of those making up normal substances <noun.substance>
antimatter \an`ti*mat"ter\ ([a^]n`t[i^]*m[a^]t"t[~e]r), n. (Physics) Matter whch is composed of antiparticles such as antiprotons, positrons, and antineutrons. [PJC]
If there were fewer than three families of basic particles, the universe would contain equal amounts of matter and antimatter, said David Schramm, a University of Chicago astrophysicist.
A $400 million investment could help scientists harness antimatter, perhaps leading to faster spacecraft and better ways to treat cancer and detect flaws in complex machines, a Rand Corp. study says.
