论文摘要
长臂猿和鹰[物理学。 Rev. D 15，2738（1977）]表明，De Sitter空间的地平线以与黑洞的事件范围相同的方式散发出辐射。但是实际的宇宙学视野不是事件范围，除了在保姆空间中。然而，本文证明了长臂猿的辐射公式，这是任何平坦空间以严格阳性哈勃参数扩展的确切结果。该论文给出了视觉和直观的洞察力，了解了为什么是这种情况。该论文还指出了宇宙学范围与动态CASIMIR效应的关系，这使实验室类似物成为可能。
Gibbons and Hawking [Phys. Rev. D 15, 2738 (1977)] have shown that the horizon of de Sitter space emits radiation in the same way as the event horizon of the black hole. But actual cosmological horizons are not event horizons, except in de Sitter space. Nevertheless, this paper proves Gibbons' and Hawking's radiation formula as an exact result for any flat space expanding with strictly positive Hubble parameter. The paper gives visual and intuitive insight into why this is the case. The paper also indicates how cosmological horizons are related to the dynamical Casimir effect, which makes experimental tests with laboratory analogues possible.
