Description
The standard cosmological model, namely the flat LCDM model, has been tremendously successful in describing cosmological observations for over two decades. Still, it suffers from theoretical caveats, in addition to recent problems like the SH0ES tension between H0 measurements from the early- and late-time Universe. In light of these issues, I will show results of some null tests of fundamental assumptions underlying the standard model in a model-independent fashion, such as a null test of the FLRW assumption, the variability of the speed of light, and the evidence for late-time cosmic acceleration.
