Physicist Michael Guillen Locates Theoretical Divine Boundary at Cosmic Horizon

American physicist Dr. Michael Guillen continues to assert a theory proposing a specific location for the divine, anchoring the concept of God at the universe's Cosmic Horizon. This assertion, which gained public traction at the start of 2026, deliberately intersects established astrophysical principles with theological interpretations of scripture.

Dr. Guillen, who holds a triple doctorate in physics, mathematics, and astronomy from Cornell University, previously served as an award-winning physics instructor at Harvard University and an Emmy-winning science correspondent for ABC News for fourteen years. His core calculation places this theoretical boundary at approximately 439 billion trillion kilometers, or 273 billion trillion miles, from Earth. This immense distance corresponds to the point where the recessional speed of distant galaxies, governed by the expansion of the universe, theoretically reaches the speed of light, 186,000 miles per second.

This boundary is scientifically defined as the Cosmic Horizon, representing the farthest limit of the observable Universe, a concept built upon the foundational research of astronomer Edwin Hubble, who established in 1929 that galaxies recede from us at speeds proportional to their distance. Central to Dr. Guillen’s argument is the application of Albert Einstein's relativity, suggesting that at this extreme distance, time dilation causes time to effectively cease, resulting in a state of absolute “timelessness.” He correlates this timeless realm with biblical descriptions of the highest level of Heaven, contrasting it with lower levels described as Earth's atmosphere and outer space.

Guillen further posits that the region beyond the Cosmic Horizon is populated by what he terms "light-like entities," aligning with scriptural references to non-material, immortal beings. This framework positions the location as inherently inaccessible to humanity, regardless of technological advancement. Despite the scientific skepticism regarding the metaphysical implications, Dr. Guillen, who also hosts the Science + God podcast, maintains his theory. His professional background includes teaching physics at Harvard for eight years and serving as the Science Editor for ABC News, where he was an Emmy-award-winning journalist appearing on programs like 20/20 and Nightline.

The scientific community largely views this assertion as a theological proposition rather than a verifiable scientific conclusion, noting that the Cosmic Horizon is an observer-relative concept, not a physical wall. Mainstream astrophysicists contend that the idea of time stopping at this boundary is a misinterpretation of light dilation caused by universal expansion. Furthermore, the limit of observation simply means light from more distant regions has not yet reached us; the universe continues beyond this observational edge. The ongoing dialogue highlights the persistent tension between empirical cosmology and the human endeavor to reconcile scientific models with ancient spiritual narratives concerning the universe's ultimate structure and boundaries.
