The Scale of the New Internal SpaceComparing Sizes • Assuming you weigh about 150 lbs, you are about 4 x 1028 or • 40000000000000000000000000000 times heavier than a proton. • Assuming you have a radius of about 0.5 meters you are about 4 x 1014 or 400000000000000 times larger than a proton.
If you were a proton, the electron, the size of a pea, would be about 21,160 meters or 13.1 miles away.
The electron 13.1 miles away would be about the size of a pea. • It would exert an electrical attraction of about 7,370,000 lbs. on you. (This is scaled by size not weight so it is a conservative estimate.) • The gravitational pull would be only 3.3 x 10-33 lbs.
If you were the Sun, the entire Solar system would fit in a 2.65 mile radius. The Earth would be 1mm, 100 yards away. Jupiter would be 1cm 600 yards away.
If you were a proton in a nucleus with other protons you would be about 1.6 meter or 5.2 feet away, about two chairs over. • You would be repelled by electrical forces from this other proton with a force of 1.25 x 1015 lbs or • 1,250,000,000,000,000 lbs. !!!! • The actual force between two protons is 3.2 lbs!
The Energy stored in the Nucleus is almost unimaginable If you were to give off a gamma ray, you would release 1.1 x 1021 Ev, which is 176 watts/sec or 129 ft.-lbs.A beta particle would release you would release 3.96 x 1021 Ev, which is 633 watts/sec or 464 ft.-lbs.
Your electron would appear and disappear in different places near the 13 mile radius.
The Uncertainty PrincipleWerner Heisenberg 1925 • It is impossible to simultaneously determine the exact position and momentum of any piece of matter. If we know where it is, we can’t measure where it is going, and vice versa.
