Then we'd be able to see the galaxies behaving in different ways despite similar masses.
What you're proposing is not one or two laws of physics being in flux--it's all of them being in flux in such a way that the net effect is exactly zero in terms of stellar luminosity, gravitational attraction, etc. That's not only a gross violation of Occam's Razor, it also makes no sense from a theistic viewpoint: If we believe in One God as both the Creator and the Lawgiver, and we believe that He is unchanging and constant, why would we hypothesize that He is constantly changing the laws of reality in a way that we can't even observe the effects?
There's a similar problem for those who posit that God created the light of distant stars and galaxies in transit to give the universe an appearance of age: Quite aside from the very obvious question, "Why bother?" that means that nothing outside of 6-10,000 light-years actually exists, and God made the universe to lie to us. That is, when we see the light of a supernova in the next galaxy over, the star it's apparently coming from never existed, and it's all a lie.
Either way, you end up with a "universe" that is either Lovecraftian or the Matrix, and a God very different from the One who presents Himself in the Bible.
I don't think God is deceptive. I do think that it's possible to misinterpret both the record of nature and the words of the Bible, but I don't think that the Lawgiver gave us constantly shifting laws just to mess with us.

Is it blasphemous to try and postulate what and how the where/when which Angels inhabit? Without time events do not occur and without space things do not exist. I believe the Bible, so I believe Angels exist ... in some where/when. I’m just deeply involved in thinking ‘how God did it’.
