When Morpheus from the Matrix tells us about why the machines use human body heat together with some sort of fusion in order to derive energy, why didn't the machines simply use nuclear, fusion, electromagnetic, geothermal or any given other energy type from our current civilization level (if they are indeed so advanced why not use the energy of the spin of the stars or better yet create one in a vacuum)?
The only explanation is if base reality had a completely different set of physics than the simulated one, the simulated reality would include manufactured "lies" or differences than base reality, what would the simulators possibly gain from creating 30-40 such differences in the simulated reality? Wouldn't simulating a reality according to the physics of the base reality be easier?
It seems that all the evidence seems to point to the contrary and that we almost certainly are in base reality.
