So how does that make me wrong? Everything exists at the exact same time as everything else. Time is relative. it's you that keeps confusing relative time with travel time.
If you were to get in a space ship and travel near the speed of light and go 4 light years away and back, you’d return to earth and only have aged a few weeks while everyone here aged 4 years.
If you go 100 light years, you might age a year, while everyone on earth aged 100 years. That’s how this stuff works. So in a sense there is ‘time travel’ when it comes to gravitation and velocity.
It doesn’t matter if you believe in it or not, it’s a scientific fact.
Time does run slower in orbit do to relativistic effects (time dilation). And it must be taken into account when using GPS or they’d be worthless. And it’s an entirely separate matter from the lag in time it takes signals to get from satellites to receivers, which must also be taken into account

My father is dead. He does not exist now. I do exist now.
