So if this logic is applied to the universe (can it be applied to the universe?) then what is the universe in that is bigger than it so that it is able to expand continuously?

Best answer: The moon would cause double the amount of gravitational pull than it currently does, which could result in severe earthquakes and tsunamis across the earth, however, if moved double the distance away from the earth, nothing would be noticed.

Best answer: Not for a long time. Current activity is concentrated on the Moon and Mars and an Earth orbiting space station. After that, the moons of Jupiter would be next. Europa evidently vents water to the surface. Sites where that is happening would be of interest. The first step would be a satellite to map the surface of... show more
