hollow earth hypothesis

A hypothesis proposed by some that states the earth is hollow and may have people or tiny suns inside of it. Jules Verne used this idea in a story of his, The Journey to the Center of the Earth (sorry I can't italicize on this phone).
Others believe were on the inside of the earth and outer space is inner space. However its proved that space is expanding so that's debunked.

Jon believes the earth is hollow on the inside, so he is an adhereant to the hollow earth hypothesis.

Hollow Point

A type of bullet that has a lead core and a swagged jacket but leaves the front portion of the projectile exposed. Within the exposed lead is a cavity that can be as much as 2/3 the diameter of the bullet. The purpose of the cavity is to initiate rapid expansion of the projectile on impact there by creating a larger wound cavity,earlier into the penetration depth. As a bullet expands, the wound cavity grows generating more shock and tissue damage. A hollow point projectile can double in diameter if properly designed. For example, a .40 caliber round can become over 3/4 of an inch in diameter after being fired into a "soft" target( I.E. living tissue)
