Let's not forget, apart from distance, the fireball is expanding in all directions. At 1" from the center, you're exposed to half the fireball. At 1 mile from the center, you're exposed to a tiny spherical arc of the fireball.

The energy is going in every direction, not just at you. With distance, you will receive a smaller portion of whatever energy made it 7 miles out.




That's what he just said, the inverse square law. You're describing the same phenomenon.
