What is Universal age paradox

Universal age paradox: The two most straightforward techniques of computing the age of the Universe -- via red-shift measurements, and via stellar evolution -- outcome incompatible outcomes. Recent (in mid 1990s) measurements of the distances of far-away galaxies via the utilization of the Hubble Space Telescope point out an age much less than the ages of the oldest stars which we compute via stellar evolution theory. At current there is no termination to this paradox; a cosmological constant would remedy the state, however it's possible that the discrepancy will vanish with more correct measurements of the age of the Universe employing both techniques.
