# How could they survive and move that easily on Miller's planet if the gravity field is so powerful?

In Interstellar the crew lands on a planet near a black hole, where the gravity field was so powerful because of the black hole that they had spend many years on the planet (relative to their station).

They freely walked on this planet. The planet's and Gargantua's gravity together did not give such a powerful field, so they could walk on the planet, so they couldn't spend so much time on the planet, right?

I thought that time distortion couldn't be big if they didn't feel big gravity on those planet.

• The planet they landed on was in orbit around Gargantua, so they experienced as much 'force' from Gargantua as someone in the ISS feels of Earth's gravity. The time dilation effects of Gargantua (or Earth) still apply. Sep 30, 2015 at 14:15
• Good question. You would think that a gravitational force massive enough to produce a 7 year to 1 hour time dilation, would be strong enough to be felt physically. The black hole is strong enough that Miller's planet is Tidally Locked, so it doesn't even rotate on it's own axis any more.

• @cde Why would it be felt physically? They're orbiting around the black hole. We don't get sucked towards the sun either. (Besides that you might also want to upvote the question if you think it is a good one.) Sep 30, 2015 at 14:52
• @NapoleonWilson because we only feel 0.0006g's from the sun, compared to the 1g from the earth at sea level. The distance from the sun is great enough, and the mass of the sun low enough compared to the mass of the Earth, and humans so small that it's negligible on human scale. Yet the Sun and moons produce tidal waves, causing ocean water to stretch 1 meter. Gargantua is so freaking massive that it bends space time on a scale of 61360 to 1 at the edge of its event horizon. It boggles the mind that it would have no noticeable effect.

• @cde Being tidal locked doesn't mean you'd have to feel the gravity of the black hole while on the planet. The Moon is tidal locked to the Earth. Yet when walking on the Moon you don't feel a lot of the Earth's gravity. But I am not even sure that planet was tidal locked to the black hole. I don't think the tidal waves seen on that planet would be possible if it was indeed tidal locked. Oct 5, 2015 at 7:57
