Time Travel Can Only Be Done Into The Future…For Now
A lot of the time when we think of time travel, we speak about how we’d go back in time. However, this is not exactly an easy thing to do. The reason for this is mostly down to the fact that we are unable to physically go back to change what already happened. However, we can shape our futures and therefore travel into the future possibly hundreds to thousands of Earth years.
An Earth Year is nowhere near the same as a year in spacetime nor can it be compared to a year on a distant planet. If one spends what they believe is an Earth Year physically traveling through space and comes back to Earth…we already know timewise things may not add up. However, depending on how far and fast they are traveling…they could very well hop into the future several Earth years ahead. Yet they won’t physically experience the change.
They’ll come back after spending just a year away to see Earth hundreds to thousands of years later. They will not have changed but generations of their family line would have already passed. Yet right now, this concept is only available when using spacetime and cannot be experienced on a planet. You could not gain the speed necessary and you’d need to deal with gravitational laws that spacetime won’t have as much of a problem with, at least outside of G-Forces.
