Description
From the perspective of Particle Physics, Dark Energy is a low energy phenomenon. Thus, our expectation is that field theory in curved space time should be sufficient to understand the physics of Dark Energy. However, in the context of the Standard Model of Particle Physics obtaining fields with sufficiently low masses that can be protected technically and be relevant for Dark Energy physics is a challenge. Pseudo Nambu Goldstone Bosons tied to non-zero Neutrino masses provide an approach to the Dark Energy problem that is promising. This approach solves the traditional problems that Dark Energy was invented to solve and provides avenues to explore the connected areas of physics, cosmology and astrophysics. As examples of this, we will discuss the collapse of dark energy field configurations to form SMBHs (Super Massive Black Holes) with masses comparable to the masses at the centers of galaxies. Moreover, the gravitational waves produced by dark energy fields can explain the periodicity of the Ice Ages through the amplitude and frequency of the ellipticity variation of earth’s orbit created by such Dark Energy Gravitational Waves. Further, the family structure of neutrinos leads to multiple phase transitions during the recent history of the Universe providing a mechanism for the production of Dark Energy Black Holes and Quasars at high redshifts as predicted by us earlier and recently observed by the James Webb Space Telescope (JWST). Finally, we discuss future directions and point out some of the exciting avenues that still need further exploration including the high energy consequences of the flavor symmetries that are responsible for the rich cosmological observations – these explorations will undoubtedly shape our ever expanding understanding of our Universe.
