Cosmic inflation is wrong. Inflation is an artifact of trying to contrive an idealized model of a universe that starts from singularity rather than as a localized event that started from some finite initial condition as it exists within an ostensibly infinite hierarchical universe.
What we see as the Big Bang is a local finite physical phenomenon embedded (like all cosmologies before it) in a much larger, diverse hierarchical universe. There is no smallest particle. There is no largest structure. All homogeneity finite in extent.
