I am traveling past earth near the speed of light, I see an 80kg (rest mass) man standing on a scale and it reads 80 kg. However, due to special relativity I see the mass of the earth and the man are both doubled and hence the gravitational force between them should be 4 times and the scale should read 320kg. The reading on the scale display can't be both 80kg and 320kg.
What is the explanation?
I did search both the web and stack exchange and could not find an answer. I saw the "duplicate post" before posting and it refers to a moving mass on a stationary surface whereas this case is 2 masses that are stationary relative to each other and a observer moving relative to both, I see this as a different case and look forward to any solutions.
