Theoretically speaking, if you had a ladder connected from Earth to the Moon, could you just climp up? Would you be able to escape and re-enter Earth's gravity? Would zero-g be instant at a certain alritude or would it be gradual?

You would probably die

The earth rotates faster than the moon orbits. In order to answer your question I need to know how it moves with the earth

Jesus fucking Christ, hypotherically speaking for fucks sake.

It's on a railroad on the equator, the guy is wearing a space suit, he won't need to shit for the rest of his life -- who gives a fuck.

The ladder would break before you even got high in Earth's atmosphere.

Ok I can answer now (it's actually really important that the ladder is rotating at the moons angular speed)

Assuming you don't fatigue yes you could climb up all the way to the moon.
Because you aren't in a stable orbital path until you get to the either the moon or a special point on the ladder where all the forces cancel out you wont experience zero g until you get to the point on the ladder where the force of earths gravity plus the force of the moons gravity is equil to the centripetal force necessary to maintain a circular orbit at that altitude and velocity.
After that point gravity would increase I the opposit direction as you enter the moon's sphere of influence

If you're gonna ask inbred potato level retard captain obvious questions, the least you can do is know your place and be as humble and as apologetic about it as fuck.

Seeing as instead, you're just a rude little prick of a douche in addition to being such a major retard, the only answer I'll give is this: Stick that ladder sideways up your fucking ass and see what that does to your equator, and you'll have your answer.

Do you know the formula for the gravitational force?

>> No.7150916

>>7150888
apparently not..

>> No.7150952

Yeah, why wouldn't you be able to? Climbing a ladder requires an exerted force all the way up.

You can fight gravity up until there's no gravity, just make your way through space, guiding yourself through space with the ladder, and finally entering he moons gravity as you climb down the ladder.

What exactly would stop you?

>> No.7150956

>>7150952
You need heat, air, and protection from radiation in space. Even if you built the mythical ladder to the moon, you'd need a space suit for a sizable portion of the journey, not to mention the fact that its a really long way to have to manually climb.

An escalator to the moon would be easier.

I'm sorry, but hypothetical or not, this is a stupid question.

>>7150845
You'll never reach zero G. Astronauts and satellites don't float because there's no gravity, they appear to float because they're in freefall around the Earth. If you climbed a ladder half way to the moon then jumped off, you'd still fall back to Earth.

>> No.7151006

>>7150845
lets be slightly less retarded and attach the ladder to a satellite in geostationary orbit, now would it work?

yes but ONLY THEORETICALLY

Yes of course, given you specific set of conditions, your specific set of conditions exists. Are you fucking happy?

I'm going to paraphrase this before any hypothetical situation from now on

gradual very slow. Spaceships are in orbit because their lateral speed is faster than the earths pull: they're constantly falling but misses the horizon.
On your ladder gravity would lower because: >distance from earth
>the rotation imparted on the moon-ladder system.
on a stationary very high ladder ad the equator you'd need to climb to geostationary orbit before gravity disappears, and as you climb furhter you need to change direction and climb downwards. The moon-earth train track ladder would force you to climb much futher before it's a downwards climb to the moon.

Also the moon is far away. If you can climb as fast as you walk(4km/h) you'd need to climb around the clock for 11 years before you reach the moon.
