Why not? Because these current theories represent opposing laws, and the universe is most certainly unified. (On the most fundamental level, Einstein’s Relativity theory leads to a smooth geometrical world while the other, quantum mechanics, leads to a non-geometrical world of violent fluctuations and graininess.)
The result of this is that there is no quantum understanding of gravity, pointing to a flaw in contemporary science’s understanding of the physical universe.
Theologian Emanuel Swedenborg was guided by the Lord God to first discover physical laws that would promote unity through mathematically precise harmonies (common equilibriums) from successive centers of gravity. This cosmic harmony, when elevated to a higher level of knowledge, corresponds to God’s Divine Love advancing as truth in series.
This knowledge is our future.
I will explore these unifying ideas in my next book, hopefully to be finished by Christmas!
