论文摘要
根据新的疲倦宇宙学模型，其中H（Z）= H 0（1 + Z），在过去的10个GYR中，星系的数量密度几乎是恒定的，至少这意味着就星系计数而言，宇宙一直是固定的。在这种情况下，对类星体和超新星IA的光度距离的分析表明，宇宙远非如今的透明，而是沿着视线的光子寿命是哈勃时间的三分之一。如此低的值可能意味着在银河系间介质中有大量的灰尘，这些灰尘已经逃脱了检测。它也可能是新物理学的签名，即光子腐烂成较轻的颗粒的结果。如果显示远程事件的时间稀释具有一般特征，也就是说，如果在超级新星IA的光曲线以外的其他现象中肯定会观察到，那么本研究中主张的疲倦模型将被伪造。另一方面，需要进一步的发展才能将这种模型变成实际的宇宙学。特别是，宇宙在银河尺度上的当前稳定性的物理起源仍有待鉴定。
According to a new tired-light cosmological model, where H(z) = H 0 (1 + z), the number density of galaxies has been nearly constant over the last 10 Gyr, at least, meaning that, as far as galaxy counts are concerned, the Universe has been stationary. In this context, an analysis of the luminosity distances of quasars and supernovae Ia shows that the Universe is far from being as transparent as assumed nowadays, the photon lifetime along the line-of-sight being one third of the Hubble time. Such a low value could mean that there are huge amounts of grey dust in the inter galactic medium, that have so far escaped detection. It could also be a signature of new physics, namely, a consequence of the decay of photons into lighter particles. The tired-light model advocated in the present study would be falsified if, for instance, the time-dilation of remote events were shown to have a general character, that is, if it were definitely observed for phenomenons other than the light curves of supernovae Ia. On the other hand, further developments are needed in order to turn this model into an actual cosmology. In particular, the physical origin of the current stability of the Universe on galactic scales remains to be identified.
