1. How do you know that?
2. If that were true, then what about the planets in our solar system? For example, Mercury, Venus, Mars, Jupiter, Saturn, the moon, and the sun can be observed with the naked eye; we can measure the distances between them, as well as the distance between each one of them and earth - it has stayed constant over time. In the absence of gravity, why would they stay at the same approximate distance from each other and from earth?
