Many of us now accept that lights falling from the sky are rocky interlopers from the asteroid clouds within our solar system, rather than visiting angels or signs from an angry (or mysteriously benevolent) God. New analysis of the meteor that overflew Chelyabinsk in Russia in 2013 suggests that one of the key founders of Christianity may have witnessed a similar natural phenomenon around two thousand years ago. However, at the time, Saul (later to become Paul the evangelist) interpreted the dazzling light on the road to Damascus — Acts of the Apostles, New Testament — as a message from a Christian God. The rest, as they say, is history. Luckily, recent scientific progress now means that most of us no longer establish new religious movements based on fireballs in the sky. But, we are awed nonetheless.

From the New Scientist:

Nearly two thousand years ago, a man named Saul had an experience that changed his life, and possibly yours as well. According to Acts of the Apostles, the fifth book of the biblical New Testament, Saul was on the road to Damascus, Syria, when he saw a bright light in the sky, was blinded and heard the voice of Jesus. Changing his name to Paul, he became a major figure in the spread of Christianity.

William Hartmann, co-founder of the Planetary Science Institute in Tucson, Arizona, has a different explanation for what happened to Paul. He says the biblical descriptions of Paul’s experience closely match accounts of the fireball meteor seen above Chelyabinsk, Russia, in 2013.

Hartmann has detailed his argument in the journal Meteoritics & Planetary Science (doi.org/3vn). He analyses three accounts of Paul’s journey, thought to have taken place around AD 35. The first is a third-person description of the event, thought to be the work of one of Jesus’s disciples, Luke. The other two quote what Paul is said to have subsequently told others.

“Everything they are describing in those three accounts in the book of Acts are exactly the sequence you see with a fireball,” Hartmann says. “If that first-century document had been anything other than part of the Bible, that would have been a straightforward story.”

But the Bible is not just any ancient text. Paul’s Damascene conversion and subsequent missionary journeys around the Mediterranean helped build Christianity into the religion it is today. If his conversion was indeed as Hartmann explains it, then a random space rock has played a major role in determining the course of history (see “Christianity minus Paul”).

That’s not as strange as it sounds. A large asteroid impact helped kill off the dinosaurs, paving the way for mammals to dominate the Earth. So why couldn’t a meteor influence the evolution of our beliefs?

“It’s well recorded that extraterrestrial impacts have helped to shape the evolution of life on this planet,” says Bill Cooke, head of NASA’s Meteoroid Environment Office in Huntsville, Alabama. “If it was a Chelyabinsk fireball that was responsible for Paul’s conversion, then obviously that had a great impact on the growth of Christianity.”

Hartmann’s argument is possible now because of the quality of observations of the Chelyabinsk incident. The 2013 meteor is the most well-documented example of larger impacts that occur perhaps only once in 100 years. Before 2013, the 1908 blast in Tunguska, also in Russia, was the best example, but it left just a scattering of seismic data, millions of flattened trees and some eyewitness accounts. With Chelyabinsk, there is a clear scientific argument to be made, says Hartmann. “We have observational data that match what we see in this first-century account.”
