牛顿力学框架下宇宙总机械能的确定
Determination of total mechanical energy of the universe within the framework of Newtonian mechanics
摘要：
最近的天文观测表明，具有有限粒子视界的膨胀宇宙是均匀的、各向同性的和渐近平坦的。在牛顿力学的框架内，宇宙的欧几里得几何学能够确定宇宙的总动能和引力能。已经证明，宇宙的几乎全部动能都来自宇宙膨胀。宇宙的总动能和引力能都是相对于任意位置的观测者而确定的。令人惊讶的是，总引力能的模与总动能的模相差一个乘数，接近一个单位。因此，我们发现宇宙的总机械能接近于零。宇宙的总动能和总引力能的模都被估计为它的总静止能量M* c ^2的3/10。
英文摘要：
The recent astronomical observations indicate that the expanding universe having a finite particle horizon is homogeneous, isotropic and asymptotically flat. The Euclidean geometry of the universe enables to determine the total kinetic and gravitational energies of the universe within the framework of the Newtonian mechanics. It has been shown that almost the entire kinetic energy of the universe ensues from the cosmological expansion. Both, the total kinetic and gravitational energies of the universe have been determined in relation to an observer at arbitrary location. It is amazing that the modulus of the total gravitational energy differs from the total kinetic energy with a multiplier close to a unit. Thus, the total mechanical energy of the universe has been found close to zero. Both, the total kinetic energy and the modulus of total gravitational energy of the universe are estimated to 3/10 of its total rest energy M*c^2.
