AbstractThe structure of space–time is examined by extending the standard Lorentz connection group to its complex covering group, operating on a 16-dimensional “spinor” frame. A Hamiltonian variation principle is used to derive the field equations for the spinor connection. The result is a complete set of field equations which allow the sources of the gravitational and electromagnetic fields, and the intrinsic spin of a particle, to appear as a manifestation of the space–time structure. A cosmological solution and a simple particle solution are examined. Further extensions to the connection group are proposed.

Near Death Experiences

The space‐time is empirically perceived as a pre-existing property of the universe. However, a special kind of perception that takes place in near-death-experiences (NDEs) is challenging this idea. Here, I will illustrate how understanding of this particular state of consciousness (named the bodiless consciousness) helps us re-think the space‐time structure of the physical world. I first speculate that the bodiless consciousness perceives the physical world as nonlocal 4D. I then propose that the space‐time is a “derived” feature subsequent to the emergence of perception of the bodiless consciousness, rather than a pre-existing and unchangeable property. Next, I explain that the space structure only takes place in the classical (or macroscopic) world rather than in the quantum (or microscopic) world, due to its intrinsic imperceptibility to the bodiless consciousness. Without a presupposed structure of the space, the strangeness of the quantum world is expected. Then, I bring up the old measurement problem. I will argue that it is the bodiless consciousness that may entangle with the superposed state of an observed system and trigger the collapse. Finally, I will briefly discuss the potential relationship between electromagnetic wave and consciousness.
