Text: Paper by Oxford University physicist Subir Sarkar and his colleagues challenges how conclusions about cosmic acceleration and dark energy were reached. Physicists who proved cosmic acceleration shared a Nobel Prize. Sarkar used statistical analysis to question key data, but his methodology also has detractors.
"Is our Universe’s expansion speeding up?"
"Sarkar’s team found “only marginal” support for cosmic acceleration with low statistical significance"
"The difference in their approach was in how they looked at the procedures used to calculate the absolute brightness of supernovae and how their light is absorbed by dust that gets in the way"
However,
“If you look at supernovae in only a small part of the sky, it would look like you had cosmic acceleration,” Sarkar says. “But we are saying that it is just a local effect, that we are non-Copernican observers. It has nothing to do with the overall dynamics of the universe and therefore nothing to do with dark energy.”
In our real Universe there are ‘peculiar motions’ due to the local in homogeneity and misanthropy of surrounding structure. These are non-negligible, e.g. our Local Group of galaxies moves with respect to the universal expansion at 620 ± 15 ∼kms−1towards ` = 271.9±20 , b = 29.6±1.4 0 , as is inferred from
the observed dipolar modulation of the CMB temperature (Kogut et al. 1993; Akrami et al. 2018)
The Q-FFF Theory postulates however, a cyclic Multiverse.

See at:15: The multiverse is cyclic, starting and ending with zero entropy.
The zero ENTROPY Big Bang Dark Matter Black Hole String Knot Singularity is supposed of splitting into smaller black holes and evaporating into the oscillating Axion dark energy vacuum very fast rising up to a maximum ENTROPY in the middle and falling again to zero ENTROPY reaching the Big Crunch, for a new starting Big Bang.
