我们将全息原理和能量均分定律应用于弗里德曼-罗伯逊-沃克宇宙的视界，并推导出描述宇宙动力学的弗里德曼方程。我们还表明，能量均分定律可以解释为表观地平线处的热力学第一定律。一致性检查表明我们的推导对于 –1 < w < –(1/3) 是正确的，该值与最近的宇宙学观测相匹配。
We apply the holographic principle and the equipartition law of energy to the apparent horizon of a Friedmann–Robertson–Walker universe and derive the Friedmann equation describing the dynamics of the universe. We also show that the equipartition law of energy can be interpreted as the first law of thermodynamics at the apparent horizon. The consistency check shows that our derivation is correct for –1 < w < –(1/3), a value that matches the recent cosmological observations.
