关于宇宙向外压力的性质（II）
On the nature of the outward pressure in the Universe (II)
摘要：
在等离子体物理学中，定义了德拜长度\lambdaD的概念。这个长度给出了一个体积的大小，使得从外部看，内部的正电荷和负电荷相互屏蔽。考虑到在没有屏蔽的情况下会产生巨大的电势，我们推测宇宙的大小R（由光速c和年龄t给出）R \approx ct不可能比德拜长度小很多。结果是大约1/3 \lambdaD。因此，在ct大小的体积内，由于缺乏对电荷的完全电屏蔽，存在很大的电压力。宇宙不会在自己的引力作用下坍缩，我们提出的可能性是，这是由于这些电荷的排斥力的影响。可能还有其他机制。今天有强有力的证据支持这样一种观点，即空间不仅在扩大，而且在加速扩大。我们发现了一个很大的数字，5 × 1060，它将普朗克的质量单位，长度，时间，电荷e和角动量\hbar转换为宇宙的质量M，大小ct，年龄t，总电荷Q和（可能）角动量。它定义了一个质量为M \approx 1056 gr的黑洞，尺寸1028厘米，特征时间为5 × 1017秒，电荷Q为\approx 3.5 × 1061 e，最大角动量为\Hbar \approx 10121 \hbar，我们认为这就是我们的宇宙。爱因斯坦宇宙学方程的解，包括电荷Q产生的电压，与目前报道的宇宙学参数值一致。这里还提出了支持曲率参数Ωk \approx 1的隐藏值的论点。
英文摘要：
In Plasma Physics the concept of the Debye length \lambdaD is defined. This length gives the size of a volume such that from outside it the inside electrical charges, positive and negative, electrically screen each other. Given the enormous electrical potential that would develop with no screening, we conjecture that the size of the Universe R, as given by the speed of light c and its age t, R \approx ct, cannot be very much lower than the Debye length. It turns out that it is about 1/3 \lambdaD. Hence inside the volume of size ct there is an otward electrical pressure due to the lack of complete electrical screening of the charges. The Universe does not collapse under its own gravitational attraction, and we present the possibility that this is due to the effect of the repulsive forces of these electrical charges. May be there is too some other mechanism. There is strong evidence today in support of the idea that space is not only expanding but doing it in an accelerated way. We find a large number, 5x1060 that converts Planck's unit of mass, length, time, charge e and angular momentum \hbar, into the mass M, size ct, age t, total charge Q and (possibly) angular momentum of the Universe in a scale like way. It defines a black hole of mass M \approx 1056gr., size 1028 cm., characteristic time 5x1017sec, charge Q \approx 3.5 x1061e and maximum angular momentum \Hbar \approx 10121 \hbar which we identify with our Universe. The solution to the Einstein cosmological equations, including an electrical pressure due to the charge Q, is in agreement with the value of the cosmological parameters currently reported. An argument in favour of a hidden value of the curvature parameter Ωk \approx 1 is also presented here.
