Gamow-Manampiring (2)
THE RISE OF GAMOW-MANAMPIRING PERSPECTIVE (Part 2)
For example, consider the Earth-sun system. In practice, the Earth assumed to orbit the sun. The sides of the Earth that facing and facing away from the sun have different orbital radii. The oceans or objects on the surfaces of these two sides should have angular velocities (ω) and linear velocities (v, tangential velocity) respectively to their radii. The larger the orbital radius, the smaller the ω in that orbit.
The oceans on both sides are bound by Earth's gravity, forced to follow the angular velocity of Earth's center. As a result, the oceans on the "near side" have too low a linear velocity (v = ωr) and tend to deviate toward the sun. On the other hand, the oceans on the "far side" have too high a linear velocity and tend to deviate away from the sun. As a result, the oceans on both sides of the Earth bulge, as if about to break away from the Earth.
Physicist George Gamow (1962) wrote, "Thus, if there were no attraction between different parts of the material forming the Earth, it would be broken into pieces, which would be spread in the form of a broad disc all over the plane of the ecliptic. This does not happen, however, because the gravitational attraction between different parts of the Earth tends to hold it together. As a compromise, our globe becomes elongated in the direction of the orbital radius with two bulges on each side."
So, from the Gamow-Manampiring perspective:
1. Earth orbits in the Earth-sun and Earth-moon systems.
2. The oceans on both sides of the Earth are forced to orbit at the speed of the Earth's center.
3. The oceans bulge on two opposite sides of the Earth, as if trying to tear off to orbit themselves.
4. Earth rotates on its own axis, resulting in alternating high and low tides throughout the day.
