Asher Peres: VARIABILITY OF FUNDAMENTAL CONSTANTS

"Are universal fundamental constants really constant over cosmological times? Recent observations of the fine structure of spectral lines in the early universe have been interpreted as due to a variation of the fine structure constant e2/4πε0ℏc. From the assumed validity of Maxwell equations in general relativity and well known experimental facts, it is proved that e and ℏ are absolute constants. On the other hand, the speed of light need not be constant."

If the fabric of the Universe is expanding we also do expand, the solar system is expanding, our galaxy is expanding. Even a rod of 1m length is expanding. So, how can we show that the fabric of our universe is expanding if the tool with which we measure length is expanding itself? Also, if we cannot prove, then how do we know that it really happens? How can we test it?

But there is more: could it be that the fabric does not expand and we just miss something?
