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?

If you are deep in the gravity well of a planet then time for you passes slower than elsewhere, not faster.
Time dilation is a **tiny** effect for realistic scenarios. If Ben is on Jupiter then 1 year for Ben is 1 year plus half a second on Earth. If Ben is on the most massive planets we know of then the difference can be up to 10 seconds per year. So yes, in principle you would see Ben move around slower (and the light from him is redshifted), but the difference is too small to notice. You need atomic clocks to measure a difference.
