The universe is actually not conserved across the universe, as it is currently understood, because of the expansion of space.
The actual conversation of energy ‘rule’, is a bit more specific.
Comment on Study: Dark matter does not exist and the universe is 27 billion years old
HereIAm@lemmy.world 8 months agoIf the light loses energy, then it must surely lose it to something? And if your last point that energy isn’t being conserved in our universe, in which case we are either in some deep shit with the first law of thermodynamics, or our universe isn’t an isolated system.

Seems energy is not conserved.

Further into the article he says that, "It would be irresponsible of me not to mention that plenty of experts in cosmology or GR would not put it in these terms. We all agree on the science; there are just divergent views on what words to attach to the science. In particular, a lot of folks would want to say “energy is conserved in general relativity, it’s just that you have to include the energy of the gravitational field along with the energy of matter and radiation and so on.” " So energy is conserved on the whole, it’s just not conserved if you consider photons apart from their greater context.

Ok. Smarter people probably thought of this, and probably found my hypothesis to be impossible. But what if… It is the the other way around. What if photons are losing energy because they are expanding spacetime. Like tiny little springs expanding out.
