全息暗信息能量:预测的暗能量测量

Holographic dark information energy: Predicted dark energy measurement

Michael Paul Gough

摘要:

已经提出了几种模型来解释导致宇宙膨胀加速的暗能量。在这里,全息暗信息能量(HDIE)模型预测的加速度与宇宙学常数产生的加速度进行了比较。虽然与低红移(z<1)下的宇宙学常数相同,但HDIE模型在较高红移(z>1)下导致较小的哈勃参数值,在z~1.7附近达到2.6 +-0.5%的最大差异。下一代的暗能量测量,无论是计划在太空中进行的(欧空局的欧几里得和NASA的WFIRST任务),还是在地面上进行的(BigBOSS,LSST和暗能量调查),都应该能够确定这种差异签名是否存在。因此,HDIE模型是可证伪的。

英文摘要:

Several models have been proposed to explain the dark energy that is causing universe expansion to accelerate. Here the acceleration predicted by the Holographic Dark Information Energy (HDIE) model is compared to the acceleration that would be produced by a cosmological constant. While identical to a cosmological constant at low redshifts, z<1, the HDIE model results in smaller Hubble parameter values at higher redshifts, z>1, reaching a maximum difference of 2.6 +-0.5% around z~1.7. The next generation of dark energy measurements, both those scheduled to be made in space (ESA's Euclid and NASA's WFIRST missions) and those to be made on the ground (BigBOSS, LSST and Dark Energy Survey), should be capable of determining whether such a difference signature exists or not. The HDIE model is therefore falsifiable.
