Physicist Michael Guillen Proposes the Cosmological Horizon as the Physical Location of the Divine

Dr. Michael Guillen, a distinguished theoretical physicist with doctoral degrees in physics, mathematics, and astronomy, has proposed a provocative theory regarding the physical location of the divine. Formerly a faculty member at Harvard University, Guillen suggests that the celestial realm, or Heaven, may be situated at the cosmological horizon. According to his calculations, this boundary lies approximately 273 sextillion miles—or 439 sextillion kilometers—away from our planet. This hypothesis, which gained attention through his writings in early 2026, represents a unique attempt to bridge the gap between modern cosmological science and traditional theological concepts.

The foundation of this theory rests on pivotal astrophysical discoveries made nearly a century ago. In 1929, Edwin Hubble demonstrated that the universe is in a state of constant expansion, with the velocity of receding galaxies being directly proportional to their distance from Earth, a principle now known as Hubble’s Law. The cosmological horizon marks the specific threshold where the speed of recession reaches the speed of light, which is 186,000 miles per second. Beyond this point, light can never reach an observer on Earth, creating a fundamental limit to the observable universe.

Guillen interprets this physical boundary through a spiritual lens, drawing parallels to biblical descriptions of a kingdom that is "eternal" and "beyond time." Under Albert Einstein’s special theory of relativity, physical matter cannot reach or exceed the speed of light, making this horizon an impenetrable barrier for material objects. Guillen posits that matter existing beyond this limit would take on "timeless" characteristics. In this view, the region past the horizon mirrors the descriptions of Heaven, where the linear progression of past, present, and future ceases to exist, even as spatial dimensions remain.

Furthermore, Dr. Guillen speculates that the "hidden universe" beyond this threshold is inhabited by entities composed of light. He links this to the holographic principle, which suggests that the information of our three-dimensional reality might be a projection of data stored on a two-dimensional surface. This intellectual pursuit is deeply personal for Guillen; his transition from a staunch atheist to a devout Christian is chronicled in his book, "Believing is Seeing." His work seeks to provide a scientific framework for the spiritual convictions he has embraced later in his career.

However, the scientific community has met this hypothesis with significant skepticism. Critics argue that there is a vital distinction between an optical limit and a physical one. They contend that the cosmological horizon is a concept dependent entirely on the position of the observer rather than an absolute physical wall. The perceived "timelessness" is viewed by many as an optical illusion caused by extreme redshift and the expansion of space, rather than a change in the fundamental nature of time itself. Unlike a static model, the observable portion of an expanding universe can actually fluctuate or shrink over vast periods.

To address the uniformity of the universe despite the constraints of light speed, mainstream science often relies on the inflation theory proposed by Alan Guth in 1981. This highlights the divide between established physical models and Guillen's more speculative interpretations. While physics utilizes the Hubble Constant to estimate the age of the universe—with figures ranging from 6 billion to 25 billion years—Guillen uses these same metrics for metaphysical exploration. It is worth noting that Edwin Hubble himself, who first confirmed the existence of galaxies beyond the Milky Way, was not a religious man and never intended for his work to support biblical narratives. Nevertheless, Guillen’s hypothesis continues to spark debate over the intersection of empirical data and religious doctrine.
