"In General Relativity it is well-known that any change of spatial energy density is a priori a curvature of spacetime, and that an EM wave is an oscillating change of spatial energy density, hence an oscillating curvature of spacetime. So the EM wave does propagate in curved spacetime; in fact it identically is "curvature of spacetime" dynamics that is propagating." Bearden; Novel Electromagnetic Disease Induction and Its Weaponization
In the early part of the 21st century, Myron Evans developed a new unified field theory which he called the Einstein Cartan Evans theory (ECE theory). The ECE theory showed the flaw in Einstein's theory of General Relativity. Not only can spacetime be curved to create gravity, it also spins to create all the electromagnetic effects. In fact ECE theory demonstrates that all physical phenomena can be explained with 4 dimensional geometry that includes spin and torsion and is a truly unified theory that unifies quantum mechanics, electromagnetism and gravitation. The ECE theory is explained at length at websites like www.aias.us and www.upitec.org
“Space-time tells matter how to move; matter tells space-time how to curve.” [John Archibald Wheeler]
Dialogue on Awakening
"...there is not time, there is no space, there is no way for us to be apart because the Mind of God is whole and within that wholeness lies the Mind of His Son and neither are separate from each other or from any infinite aspect of Itself as It is expressed." Dialogue on Awakening, page 143.
"In the interpretation of the universe, we find that time and space are concepts of the mental mind." [Cayce, 1747-5]
"Time, Space, and Patience in a three-dimensional world are like the Truth manifesting itself into the experiences of souls, leaving impressions upon people's minds so they're expressed through faith, hope, and love." [Cayce (1463-1]
