Let's try this again. I typed in 'c' for 'v' by mistake in the eariler question. My bad.

So, about the equation ' E=1/2MV^2' ? Can the answer to practical space travel be found in this equation?

Thalidomide has two distinct forms. One form (1) acts as sedative and sleep aid whereas the other (2) causes terrible birth defects. Strangely, both have the same chemical formula, C13H10N2O4. The differences between the two are entirely due to the different arrangement of the atoms in space.

Why two molecules with the same chemical formula may still have different connectivity and geometries?

Supposing Earth had a second moon of comparable size as our currect moon, what effects would that have on Earth?

Here's a couple scenarios:

(1) The second moon on exact opposite side of the planet, both moons had the same orbits.

(2) The second moon directly behind our moon, an equal distance from that moon as the first has to Earth, and both having the same orbit.

(3) The second moon directly behind our moon, an equal distance from that moon as the first has to Earth, but in one case has an orbit 2x as long as our moon, and in another case half as long.

As a bonus, what would happen if instead of a moon it was a planet with oceans of it's own? How would Earth and moon affect its oceans?
