Why do eggs crack when boiling?

The bottom, rounded end of an egg contains a small air bubble. As the egg heats up, the air inside the bubble expands. As the hot air pushes outwards, it puts pressure onto the shell, making it crack.

What happens if you boil an egg for 45 minutes?

According to FoodSafety.gov, when you boil an egg for too long, sulfur and iron compounds react on the surface of the yolk, creating this icky color. Or, this might happen if there's a high iron content in your cooking water. But, that's it. This is safe to eat.

Why is hard boiled egg yolk GREY?
