A glitch in gravity: cosmic Lorentz-violation from fiery Big Bang to
glacial heat death
A glitch in gravity: cosmic Lorentz-violation from fiery Big Bang to
glacial heat death
One regime where we might see departures from general relativity is at the largest accessible scales, with a natural choice in cosmology being the cosmological horizon (or Hubble) scale. We investigate a single-parameter extension to the standard cosmological model with a different strength of gravity above and below this scale …
