I get how traveling near a larger mass than earth would cause a person on earth to see the traveler as taking a longer time, BUT...
In what scenario would a person on Earth see a traveler as only having been gone a short time, whereas the traveler may have felt like they have been gone for years?
All I can think is put the earth near a large mass or speed it up. But there's not much the traveler can do besides sitting still near no mass, right?

The neutral orbit (SR+GR=0) is at r≈(3/2)*R_Earth. Clocks in a lower orbit tick slower than on the surface, above that clocks tick faster.

So based on that, a clock would tick faster away from Earths gravity, but not at any significant rate. For instance there isn't a scenario where one earth month is ten space years, at least not without screwing with Earth right?

Should it not be possible then to see a duplicate of a star on both sides of a large mass?

are you saying that anti-matter, black holes, and time dilation are paranormal?

I'd also like to hear the answer to this.

Obviously.

Have the traveler move toward earth close to c

that's basically how relativity works
we're pretty far from being high-mass and high-speed, so your only option (aside from putting earth near like, a black hole, and travelling super fast) is to just have the other person just sit completely still far from any sources of gravity. That probably wouldn't cause much of a difference, though, but it WOULD be measurable.

also, while it's borderline pseudoscience for me to suggest it, there's a lot that's not known about time and why it does what it does (there are ideas floating around) but there are more options that might become available in the future (such as what quantum mechanics might open up), but AFAIK relativity is the only feasible way of "manipulating" time
