I’ve been thinking about gravity and time. I get that percieved time changes depending on which planet you’re on, more gravity= faster time is. I also understand that the person on that planet will not notice any difference.
For an example, ben teleports to a super big planet, and hangs out there for 5 hours, teleports back to earth and boom, its been 5 months in earth time.
But, if we somehome could, with a telescope, see ben on that big planet, would we percieve him as going slomo, or almost not moving?

To add on to what a lot of people are saying- your initial comment amount Gravity is backwards, but your description of Ben is about right.
This is pretty much the twin Paradox- let’s say Ben has twin who stays behind on Earth as Ben travels at near light speeds to another planet. If they both watched each other, they would see similar things. Ben would see his twin on Earth also moving very slowly. Same thing for on his higher gravity planet- the light from Earth must pass through the gravity field to reach Ben. By the time it does, it’s at a lower frame rate, so to speak.
Now Ben is done and he gets back in his ship and heads back to Earth. As he accelerates towards Earth he watches his twin. At first his twin is the same age as him- but as he heads towards Earth, his twin starts speeding around Earth, aging super fast. By the time Ben gets there his twin is an old man.
In Relativity, acceleration is key. Ben is the twin who experienced Time dilation because he accelerated away from Earth and accelerated *back*. Otherwise, just looking at each other, neither Ben nor his twin could tell who was aging slower.
