How Much Gravity Do You Actually Need?

Earth is 1 G which is our normal but hard on the knees. Earth orbit is 0 G which we know causes problems for our bodies over time. It's actually called micro-gravity, if you knock a cup off the counter it will take three years to hit the floor. The Moon and Mars are less than 1 but more than 0. If I could live on the Moon, I could still have a cup of coffee in the morning, jog 30 Km without ruining my knees and maybe finally bench 180... I wonder if there was a study? Maybe the Russians did one and never told anybody!

Gravity is only 1g aka 9.8 m/s/s at 'mean sea level'.

Go much closer to the planet's core and gravity is greater, and much much further away and it's less.

If you go to the moon how do you make water boil? 8-) Lunar gravity is drastically less because of (a) the physical size of the moon and (b) it doesn't have a molten moving core and the materials that make up the moon are different.

As it's not really possible actually go into the molten core of the planet humans as we exist today would never be able to experience high gravity near the centre of the planet.

The composition of the Earth and moon are very nearly the same, only varying in amounts. The moon has a solid iron core that is still hot (between 1,327°C and 1427°C). This is hot enough to create a surrounding molten liquid iron outer core.

Because the core is so small (~20 percent of the lunar diameter), though, its heat does not reach the surface.@zonavar68

So throw billions at the problem?

@MasterLee I don't actually have billions at the moment. Maybe one of those go fund deals..??
