If Anti-hydrogen rises in earth gravity, as now under examination at CERN, we will face having to determine if half the universe may be of antigravitating antimatter. Photons will not discernibly carry this information. Neutrinos can illuminate the conundrum.

While General Relativity holds, such a discovery would mandate a re-examination of all of cosmology, including LambdaCDM.

We do not understand the coupling of gravity to matter and anti-matter, as there is no accepted quantum field theory. 

If we live in such a universe, galaxies and clusters of galaxies and antigalaxies repel each other and form pressure barriers against annihilation. Present limits on the antimatter content of the universe assume mutual attraction and huge fluxes of annihilation gammas from such.. 

There becomes no longer any need for Dark Energy.  Hubble inflation is classical, and there remains no need for exponential metric expansion.

We will discuss several means of observing the antimatter galaxies via neutrino observations.
