That does not sound like a coincidence.
Did the constant change when the universe was smaller? Or does the light speed depend on the size of the universe?
- tehwalrus 10y agoUniversal constants changing slowly over the lifetime of the universe is one of the things I remember quite well from undergrad physics. Not as anything that has been proven, but as a meachanism to try and fix some of the astrophysics measurements. Of course, the radius of the universe has clearly changed with time- this could mean that a0 did or that c did.
- openasocket 10y agoComplete guess: it might not be a constant, but a function of the average curvature of the universe.
