Electromagnetic waves take between ~4 and ~24 minutes (mean: ~14 minutes) to travel a one-way trip between Earth and Mars. Suppose I set up a Bitcoin network on Mars. Is it guaranteed to eventually fork from the Bitcoin network on Earth?
I would expect the Bitcoin network on Mars to fork from the one on Earth, because Bitcoin's target inter-block time is 10 minutes, which is less than average time it takes for electromagnetic waves to travel between Earth and Mars. Am I correct?
