“Primordial black holes behind the origin of dark matter and dark energy"

I will briefly review the evidence we have for the existence of primordial black holes (PBH) as the main component of dark matter within a wide range of masses and clustering properties. I will then describe a recent proposal for explaining the present dark energy in terms of general relativistic entropy acceleration (GREA) induced by the rapid growth in mass of supermassive PBH at the centers of the first galaxies. We propose the use of DESI and Euclid to test this GREA theory
