论宇宙的膨胀和命运
On The Expansion and Fate Of The Universe
摘要：
宇宙从最初的戏剧性事件大爆炸开始的演化是牢固确立的。哈勃定律[1]（HL）将星系物体的速度和它们的相对距离联系起来：v（r）= Hr，其中H是哈勃常数。在这项工作中，我们认为，HL是无效的，在大的距离，因为总能量守恒。我们建议，速度可以扩大其相对距离，并产生更好的拟合现有的实验数据。使用一个简单的"尘埃"宇宙模型，我们可以很容易地计算在哪些条件下可以达到（不稳定的）平衡态，我们可以估计宇宙中存在的物质以及"暗能量"的值。我们不需要调用任何"暗能量"，它的作用是由动力学修正发挥的。由此产生的图像是，宇宙可能会达到一个不稳定的平衡态，其命运将由波动决定：要么崩溃，要么永远膨胀。
英文摘要：
The evolution of the universe from an initial dramatic event, the Big-Bang, is firmly established. Hubble's law [1] (HL) connects the velocity of galactic objects and their relative distance: v(r)=Hr, where H is the Hubble constant. In this work we suggest that HL is not valid at large distances because of total energy conservation. We propose that the velocity can be expanded in terms of their relative distance and produce a better fit to the available experimental data. Using a simple 'dust' universe model, we can easily calculate under which conditions an (unstable) equilibrium state can be reached and we can estimate the values of the matter present in the universe as well as the 'dark energy'. We do not need to invoke any 'dark energy', its role being played by the kinetic correction. The resulting picture is that the universe might reach an unstable equilibrium state whose fate will be decided by fluctuations: either collapse or expand forever.
