What if 2 copies of my mind exists in 2 different computers in 2 places of the universe, say mars and moon, and they have no link with each other. Where would I feel my awareness then, in mars, in moon or both ?
If 2 copies of your mind existed in two different locations, then each copy would develop a different personality according to the environment and the experiences it would have. From your own point of view, each "you" would still feel like yourself, and would not be aware of what the other "you" is feeling... So each "you" would consider itself as the "real you" with its own awareness (separated from the other).
