The speed of light ought to remain constant (for inertial observers). So nothing would be different locally as far as I'm aware.

- raattgift 5y agoThe speed of light (in vacuum) is constant for accelerated observers too. :-) The dipole anisotropy of the Cosmic Microwave Background will continue to be a good tool to see the constancy of the speed of light for all observers into the practically infinite future, assuming the infinite future looks a lot like de Sitter space (which is essentially what the standard cosmology predicts). http://www.astro.ucla.edu/~wright/CMB-dipole-history.html http://www.astro.ucla.edu/~wright/CMB-dipole-history.html The far future of the universe will still have generally covariant physics, as does its far past, sharpening up your second sentence.
