摘要
据实验检测和理论计算,论证了现时中微子的超对称伴子“中性微子-”U0e,B(q2,-g)是宇宙暗物质的最佳候选粒子.认为超新星爆炸释放的暗能量,迫使宇宙背景光子热平衡态的温度T、压强p上升.将压强类比为“反引力”,当“反引力”(压强)大于引力,则宇宙将加速膨胀;当“反引力”小于引力,则宇宙将收缩.
On the bases of experimental measurement and tests and theoretical calculation, the supersym- metry companions of present neutrinos, neutralinos U↑-e^0B(q2, g↑-), are proved to be the best candidate particles of dark matter in the universe, and the energy released by supernova explosion is thought to make the tempera- ture T and the pressure p of the thermal equilibrium state of universe background photons go up. If pressure is compared to “anti-gravitation”, when“anti-gravitation” (pressure) is bigger than gravitation, the universe will expand, and when “anti-gravitation” is smaller than gravitation, the universe will contract.
