中文百科
暗能量![]() ![]() ![]() ![]() 在物理宇宙学中,暗能量是一种充溢空间的、增加宇宙膨胀速度的难以察觉的能量形式。暗能量假说是当今对宇宙加速膨胀的观测结果的解释中最为流行的一种。在宇宙标准模型中,暗能量占据宇宙68.3%的质能。 暗能量现有两种模型:宇宙学常数(即一种均匀充满空间的常能量密度)和纯量场(即一个能量密度随时空变化的动力学场,如第五元素和模空间)。对宇宙有恒定影响的纯量场常被包含在宇宙常数中。宇宙常数在物理上等价于真空能量。在空间上变化的纯量场很难从宇宙常数中分离出来,因为变化太缓慢了。 暗能量这个名词是由麦可·特纳引进的。

Dark energy 暗能量![]() ![]() ![]() ![]() In physical cosmology and astronomy, dark energy is an unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe. Dark energy is the most accepted hypothesis to explain the observations since the 1990s indicating that the universe is expanding at an accelerating rate. |
