论文摘要
暗能量是当今最伟大的科学奥秘之一。自60年代后期以来，暗能量源自量子真空波动的想法已经循环，但是真空能的理论估计已与最近的数量级相反，直到最近。应用于宇宙学的Lifshitz理论为暗能量产生了正确的数量级。此外，该理论基于原子，分子和光学物理学的良好和实验经过良好测试的理由。在本文中，我们将Lifshitz宇宙学与天文数据对抗。我们发现，该理论预测的黑暗能源动力学能够解决哈勃张力，这是标准宇宙学模型中观察到的哈勃常数之间的差异。该理论与超新星的数据，重子声学振荡和宇宙微波背景一致。我们的发现表明，Lifshitz宇宙学是解释黑暗能量的认真候选人。
Dark energy is one of the greatest scientific mysteries of today. The idea that dark energy originates from quantum vacuum fluctuations has circulated since the late '60s, but theoretical estimations of vacuum energy have disagreed with the measured value by many orders of magnitude, until recently. Lifshitz theory applied to cosmology has produced the correct order of magnitude for dark energy. Furthermore, the theory is based on well-established and experimentally well-tested grounds in atomic, molecular and optical physics. In this paper, we confront Lifshitz cosmology with astronomical data. We find that the dark-energy dynamics predicted by the theory is able to resolve the Hubble tension, the discrepancy between the observed and predicted Hubble constant within the standard cosmological model. The theory is consistent with supernovae data, Baryon Acoustic Oscillations and the Cosmic Microwave Background. Our findings indicate that Lifshitz cosmology is a serious candidate for explaining dark energy.
