There have been recent cosmological experimental disclosures
represented in part by the following:

The 7Be(n,p)7Li reaction and the Cosmological Lithium Problem:
measurement of the cross section in a wide energy range at n\_TOF (CERN)
https://arxiv.org/abs/1806.03050
"The new estimate of the 7Be destruction rate based on the new results
yields a decrease of the predicted cosmological Lithium abundance of
∼10%, insufficient to provide a viable solution to the Cosmological
Lithium Problem."
What is the resolution to the Lithium problem?

No WIMPS have been found in reference to the dark matter problem.
What are the dark matter alternatives?

Collective Effects in Nuclear Collisions: Experimental Overview
https://arxiv.org/abs/1810.06978
Viscosity plays an important role in measured LHC RHIC nuclear dynamics
Does this viscosity experimental result
influence BBN gas phased mechanisms?

MILKY WAY CEPHEID STANDARDS FOR MEASURING COSMIC DISTANCES AND
APPLICATION TO Gaia DR2:
IMPLICATIONS FOR THE HUBBLE CONSTANT
https://arxiv.org/abs/1804.10655
The Planck H0 = 67.4 km/s/Mpc is based on CMB.
The reported H0 = 73.24 km/s/Mpc is based on photometric parallaxes.
What mechanism explains the difference?

The universe increased expanding rate
is an expression of dark energy measured by supernovae type II events.
What is dark energy?

The cosmological constant problem or the vacuum catastrophe
indicates a vacuum energy theory differing from experiment
by 120 orders of magnitude.
What is the vacuum energy?

Is there a common theoretical mechanistic thread
connecting these experimental dots?
