Did an Asteroid Cause Constantine's Conversion?

Scientists are speculating that an impact crater in the Italian Sirente Mountains may have prompted Constantine's conversion to Christianity. An impact crater dating from the fourth or fifth century has been discovered in the area of Italy's Sirente-Velino Regional Park. Larger than a football field, the crater, which fills with water seasonally to form a lake, would have been caused by an explosion the size of a small nuclear weapon with shockwaves and a mushroom cloud.

4th century accounts claim that Constantine had an amazing vision from the sky and converted to Christianity on the spot, going on to lead his army against barbarians which threatened his empire.

Now scientists believe that the two incidents might be linked.
