then we would know a great deal more

perhaps some day we will discover a negative wave in dark matter that has
infinite speed. one never knows...

IF light (or something containing information) was of instantaneous
speed, I'm not sure we would learn anything more....in fact, we might
even lose information; consider the fact that we can study the
early Universe right after the BB now, with light and other forms
of electromagnetic radiation of finite speed....BUT, if light (all
forms) were, say, instantaneous, then all the early Universe
information, would be forever lost to us...
in addition to the CMBR radiation.
