论文摘要
1998年,天文学家发现宇宙的扩展正在加速。不知何故,某些事情一定使重力排斥在宇宙学尺度上。这被称为黑能。爱因斯坦的宇宙常数描述了它。它相当于宇宙总质量的70%。已经猜想宇宙常数是真空能的一种形式,但是直到最近,它从量子场理论中的预测都被许多数量级失败了。 Lifshitz理论通过有关Casimir力量的经验证据得知,不仅产生了正确的数量级,而且与天文数据一致。此外,该理论似乎可以解决测得的哈勃常数之间的张力。因此,Casimir物理学很有可能解释了暗能量。本文介绍了“量子真空状态:2020年代的Casimir物理学”的一部分,介绍了真空力的实践者,由K. A. Milton编辑。对于希望对宇宙学简要介绍的其他物理学家和工程师来说,这也可能很有趣。
In 1998 astronomers discovered that the expansion of the universe is accelerating. Somehow, something must have made gravity repulsive on cosmological scales. This something was called dark energy; it is described by Einstein's cosmological constant; and it amounts to about 70% of the total mass of the universe. It has been conjectured that the cosmological constant is a form of vacuum energy, but its prediction from quantum field theory has failed by many orders of magnitude, until recently. Informed by empirical evidence on Casimir forces, Lifshitz theory has not only produced the correct order of magnitude, but is quantitatively consistent with the astronomical data. Moreover, the theory appears to resolve the tension between the measured and the predicted Hubble constant. There is therefore a good chance that Casimir physics explains dark energy. This article introduces cosmology for practitioners of vacuum forces as part of "The State of the Quantum Vacuum: Casimir Physics in the 2020s" edited by K. A. Milton. It may also be interesting for other physicists and engineers who wish to have a concise introduction to cosmology.
