This has been messing with my head for a while.
The Cheela in/on Dragon's Egg book/planet, had their time move much faster, compared to the humans out in the space. This was explained as due to the extremely high gravity of their neutron star planet. What is the fictional physics occurring on Cheela to cause the time speed up?
But in the framework of general relativityreality AND any fictional universe that acts like reality, high gravity acts to slow time down. This effect was notably portrayed in Interstellar -- when the expedition party land on the watery planet that's extremely close to a black hole, their time is slowed down, compared to the human out in space.
I'm missing something simple here. Can someone help solve this for me please?.
