oscillations in the expansion history
the age of the Universe is estimated from the inverse Hubble constant, i.e. from the current expansion speed. imagine now that the Universe underwent a series of expansion and contraction phases such that we would underestimate the Universe's true age from the Hubble constant. would there still be ways of figuring out the true age?
