Why is Venus, similar in size and composition, pulled into the sun? Isn't this a necessary result of gravitational theory? As well, obviously, Mercury, how would it achieve a balance at a distance where the gravitational force is much stronger than 1au? It's also further away from the influence of the giants as well. Presuming the Earth is in an optimal orbit relative to it's mass and composition, as science and ToR tell us, and relative to gravity, or the gravitational pull of the sun at this distance away. And gravity does get weaker with distance, but there’s still enough to hold onto Pluto and things beyond it. So, between them and the space ship, there’s no acceleration.Ĭhris - Let’s take it to it’s logical conclusion the reason that Pluto is 6 billion kilometres from where we are here on Earth and it’s still orbiting the Sun is because the Sun’s gravity is hanging onto Pluto, even though it’s that far away. They’re still experiencing the Earth’s gravity but so is the spaceship that they’re in. So zero G is not distance away from the Earth.Ĭhris - So people who are on the International Space Station, the reason that they are in orbit around the Earth is because gravity is hanging onto them and keeping them in orbit? But they’re just free-falling around the Earth all the time so that they’re weightless, but that’s not the same as zero G?ĭavid - Correct. So it’s like the lift dropping down the lift shaft. Zero G in space is because you’re in a space capsule accelerating under gravity, orbiting the Earth, or going from one body to another and you’re not accelerating : the person within the spaceship is accelerating at the same rate as the vessel. If you double your distance from the centre of the Earth, the gravity would decrease to a quarter of what it is at the surface, but that’s not zero G.
