A former Harvard physicist, Dr. Michael Guillen, has proposed a fascinating theory that links the location of Heaven to the farthest reaches of space. By combining complex science with biblical descriptions, he suggests that Heaven might exist just beyond what scientists call the “Cosmic Horizon.”
The Cosmic Horizon is the edge of our observable universe. According to the laws of physics, objects at this distance move away from us at the speed of light. Because humans cannot travel that fast, this boundary remains a permanent wall that we can never cross in our physical forms.
Dr. Guillen notes that his theory aligns with the Bible, which often describes Heaven as being “up” and away from Earth. He suggests that the highest level of Heaven is located beyond this outer limit of space. This would make it a place that is physically real but unreachable by living mortals.
Modern science indicates that time actually stops at the Cosmic Horizon. Beyond this point, there is no past or future—only a state of timelessness. This matches the traditional view of Heaven as an eternal realm. It is a place where time does not exist as we know it.
The theory concludes that the space beyond this horizon is habitable, but only for non-material beings. Since this realm predates the Big Bang, it would be the logical dwelling place for a creator. For Dr. Guillen, science and faith finally meet at the very edge of the universe.
