starlight bent by gravitational fields
Is it possible that we are seeing the same stars or galaxies at different points in the sky and at different ages because some light from the star has reached us direct without any gravitational interference, but other light emitted in a different direction has been bent on its way round the cosmos due to gravitational interference and has taken much longer to reach us and appears to come from a different point in the sky? Or is this a stupid question?
