Abstract In this paper I examine how well Ryskin’s model of emergent cosmic acceleration fits several sets of cosmological observations. I find that while Ryskin’s model is somewhat compatible with the standard model of cosmic acceleration (ΛCDM) for low redshift (z ≲ 1) measurements, its predictions diverge considerably from those of the standard model for measurements made at high redshift (for which z ≳ 1), and it is therefore not a compelling substitute for the standard model.

反对 Ryskin 宇宙加速模型的证据

摘要 在本文中，我检验了 Ryskin 的紧急宇宙加速模型与多组宇宙学观测的拟合程度。我发现虽然 Ryskin 的模型在某种程度上与用于低红移 (z ≲ 1) 测量的宇宙加速度标准模型 (ΛCDM) 兼容，但它的预测与在高红移下进行测量的标准模型的预测大不相同（为此 z ≳ 1)，因此它不是标准模型的引人注目的替代品。
