The only one talking about conspiracy theories is you. That's another strawman of your own creation. It's usually mainstream authors that blow the biggest holes in the LCDM model so if it's conspiracy is the worst conspiracy in the history of physics.
It's a bit amusing from my perspective that the only two instance where energy isn't supposedly conserved that your video author could cite, were two different metaphysical claims associated with the same otherwise falsified cosmology model. Both instances that he cited *assume* that the LCMD model is correct in spite of
significant evidence to the contrary.
The more *likely* scenario is that energy is *always* conserved and "space expansion" isn't the actual cause of redshift.
It's also amusing that the author that you cited said exactly the same thing that I did, specifically that both dark energy claims and space expansion claims violate conservation of energy laws.
If one simply assumes that plasma redshift is the real cause of cosmological redshift, a static infinite universe doesn't violate any know laws of physics. Any energy lost by photons is simply transferred to the plasma. GR theory isn't the problem, the LCMD model is the problem.
