Inhomogeneities and cosmological expansion
Nikolaos Tetradis
TL;DR
This paper reviews how inhomogeneities in matter distribution affect measurements of distant sources' luminosity distances and their implications for understanding perceived cosmic acceleration.
Contribution
It synthesizes existing research on the impact of matter inhomogeneities on cosmological observations and their role in the interpretation of cosmic acceleration.
Findings
Inhomogeneities can bias luminosity distance measurements.
Matter distribution irregularities influence perceived cosmic acceleration.
The review highlights the importance of considering inhomogeneities in cosmological models.
Abstract
I review work on the influence of inhomogeneities in the matter distribution on the determination of the luminosity distance of faraway sources, and the connection to the perceived cosmological acceleration.
