# I Gravitational time dilation

#### EasterEggs123

If a planet has gravity that is 3,000 m/s^2 instead of 9.8 m/s^2, would time passage be significantly different, or what would one second on earth be compared to one second on that planet?

Gravitational time dilation depends on the gravitational potential.

Gravitational time dilation depends on the gravitational potential.
But you can find the potential by knowing that it's 3000 m/s^2?

No.

#### H_A_Landman

You'd need to know the mass and radius of the planet. For example, The Earth has 1 G of gravity, but so does a galaxy-mass black hole with Schwarzschild radius of 1 light year. The potentials for those two cases are hugely different even though the field strength is about the same.
