Abstract

The concept of exotic charged dust is introduced here to represent dark matter. The term "exotic" means that the dust is not composed of normal matter, and the charge--for lack of a better term--is not an electric charge. It is also shown that the often-used approximate expression for dark matter density corresponds to an exact solution of the coupled Einstein-Maxwell equations for charged dust. The Einstein field equations tells us is that for a flat universe the cosmological constant acts as a gravitating negative energy distribution that is gravitationally repulsive; following Schwinger, it is shown that the vacuum must have a negative energy spectrum if QFT is to be gauge invariant.

暗物质和宇宙常数的起源
这里引入了奇异带电尘埃的概念来代表暗物质。所谓 "奇异",是指尘埃不是由正常物质组成的,而且电荷--因为没有更好的术语--也不是电荷。研究还表明,经常使用的暗物质密度近似表达式对应于带电尘埃的爱因斯坦-麦克斯韦耦合方程的精确解。爱因斯坦场方程告诉我们,对于一个平坦的宇宙,宇宙常数就像一个引力负能量分布,具有引力斥力;按照施文格的观点,如果要使 QFT 具有规整不变性,真空必须具有负能量谱。
