Hey all, Just a thought experiement here. With time dilation caused by gravity and relative velocity being a confirmed phenomena, do you think it's possible that other worlds that are extremely far away from each other, and are moving at a very high speeds relative to one another with different vastly differing gravitational fields are able to exist and play out their whole existence, relative say to only a years amount of time on another world. I am wording this question terribly, but its a lot like the twin paradox where one travels close to C realitive to his twin, and experiences a years time himself, but its like 10 years for his stationary twin back on earth. Basically, im asking if there are large enough velocity and gravity difference between planets for this to happen on a large scale (ex: after 1 year on earth, a planet on the other side of the universe experiences say a century, or millennium even. It seems to me that these time difference between planets do exist without a doubt, because we know time dilation in real, and we also know everything in the universe is moving at varying speeds to one another. I just want to know to what magnitude this would be possible. Cheers!
