"Time dialation would make it possible for passengers in a fast moving vehicle to travel further into the future while aging very little
We ALL travel through time. That's why clocks move forward. Time dilation makes them move at difference rates due to distorted local space time properties relative to body suffering the effects of the local distortion due to speed or gravity. Notice the paragraph you quote doesn't use the phrase "time travel" which you keep desperately trying to equate to "time travel". As I said, we ALL travel through time, hopwever, time dilation is exactly the term for traveling through time at different rates, not "time travel" as it is meaningless and already happening to all of us.
You were wrong, you continue to be wrong.
