Look for a system where the predictions of GR contradict, or at least interact with, the predictions of QM.
There are two main examples: Microscopic exploding black holes, and the Big Bang.
Our current fundamental physics theories are probably adequate to explain literally everything that happens in the solar system, which is one of the reasons I don’t think fundamental physics is a particularly time-sensitive topic of research. So we can just wait until we have superintelligent AGI, and ask it what the fundamental laws of physics are. :-)
This energy has no gravitational consequences because it’s pulling equally in every direction.
Although I appreciate the intuition that ” it’s pulling equally in every direction”, uniform energy density does in fact have an effect in GR. It causes the whole universe to expand or contract. That’s exactly what dark energy is.
