# What determines intensity + range of a gravity field?

How does the Sun's gravity extend out millions of miles to influence the far reaches of our solar system?

Reference: movie - "Interstellar", 2014 Nolan) / How does a ship avoid strong gravitational effects of a supermassive blackhole while orbiting a planet that is within range of those effects. Scenario: search crew descends to planet surface, leaving one behind on the orbital ship. When crew returns, after a 1/2hr delay, 7yrs transpire on the ship (something like that). So - I understand gravity warps time. My question is: how does mass influence intensity and range of a gravity field?

• Although the physicist (& renowned gravitation expert) Kip Thorne was a scientific advisor for Interstellar, not everything in that movie is scientifically accurate, so please don't take it too literally. FWIW, there are several questions on this site asking about various things in Interstellar, mostly to do with time dilation. Commented Aug 18, 2020 at 21:48
• Are you familiar with Newtonian gravity and the formula $F=GMm/r^2$? If so, you can answer your own question. Commented Aug 18, 2020 at 22:03

• Weird. Mentioning hard sci-fi movies on Physics StackExchange seems to generate its own gravitational field of contempt. Starting to feel the effects of stress-intimidation tensors in my inertial frame of reference. So much for equivalence principles in this blackhole. Time to dilate out of here.

• @safesphere - I see your point, gravity (warping of space+time) is a causal effect of mass. I was loosely referring to the gravitational field of supermassive blackhole, Gargantua, manifesting the time dilation experienced by characters in the movie who descended to the surface of a planet within the gravity well. So the original question, which has since been answered, relates to what determines the range + intensity of gravity fields. Thank you. Commented Aug 19, 2020 at 15:57
