Apollo 11 Moon Landing Revisited: Hoax ~vs~ Debunk

[Myriad]

In freefall an 80Kg astronaut weighs nothing. If he then tried to lift a 20Kg supply container, the weight ratio would be 0/0, which is infinite. The astronaut and the container would immediately collapse into a back hole. That's how we know all those videos of astronauts bouncing around inside the ISS like Sonny the Cuckoo Bird going cuckoo for Cocoa Puffs are faked.

We weren't talking about lifting or centre of gravity; just (a) how much you would theoretically weigh on the Moon and (b) your same weight as yourself backpack.

You don’t even know what you’re trying to talk about. The balance problem is the center of gravity problem. The customary way of solving that is as a vector problem. How much you would weigh on the moon irrespective of balance is a simple sum which you don’t seem to be able to get right.

Anyway, never mind.

Are you giving up on the problem?

 

[Andy_Ross]

If you are now the equivalent of 30lbs, no it would not.

Why not? I would have the same strength

 

[Foster Zygote]

I never said anything about muscles. Please read more carefully in future.

No one said you did. Please read more carefully in the future.

You claimed a man weighing 180lbs would have no problem wearing his own weight on his back on the Moon, as opposed to on Earth. I simply pointed out the ratio remains exactly the same regardless of gravity.

You were asked about muscles mass because you seem not to understand that someone who's just traveled from the earth to the moon still has the same strength they had on earth. Weight is simply a measure of gravitational acceleration, not your mass. If your weight decreases to 1/6th what it is on earth, it doesn't make you 1/6th as strong. If you weigh 180 lbs. on earth, then lifting something equal to your own weight on earth is going to be a challenge for most people. But most people can lift 30 lbs. without much trouble, and if you're standing on the moon, the fact that you now weigh 30 lbs. has no effect on your muscle strength, so lifting your own weight on the moon is literally as easy as lifting 30 lbs. on earth. In fact, it's actually easier because even your own body is over 83% lighter than on earth, so even the effort to lift your own body against gravity is significantly lessened.

This "ratios" argument is ignorant nonsense. You just like it, apparently, because it sounds sciencey to you when you use the word.

There really is no buoyancy effect on the Moon.

That's why you wrote "please read more carefully" above - because I brought up your reading comprehension issue with thinking that I was saying that there's buoyancy on the moon, simply because I attempted to use an earth-based analogy for what it would be like to wear the PLSS/OPS on the moon. You may as well have condescendingly said, "duh, there are no cats on the moon".

There is no wind to help ease the load.

Thanks. It's nice to have someone who forgot that lunar surface gravity is 1/6th that of earth then tried to cover that error with some utter nonsense about weight ratios, and who has only just recently begun to skim the information available about the Apollo Program and the relevant science and engineering for the purpose of cherry picking, inform everyone that there's no appreciable atmosphere on the moon. You've certainly established your bona fides with that arcane, esoteric, scientific deep cut.

For reference: an Earth orbit with the same period as the moon would only occur at one of the Earth-Moon Lagrange Points. These are stable, or meta-stable, positions that have a fixed relationship to both the Earth and the Moon. They also have nothing to do with the Apollo 11 communications issue. https://en.wikipedia.org/wiki/Lagrange_point#:~:text=External links-,Lagrange point,-74 languages

I think it's also worth mentioning that the illustration isn't to scale where L2 is concerned. It's actually about 1.5 million km from earth, about 6.3X farther than the moon. So a halo orbit around it would only need to be about 11-12 thousand km in radius to be always in view of earth-based antennae.

 

[Myriad]

Do you not have the wit to understand that he has bone and muscles designed to carry much more weight, but that weight is not a factor on the moon, so it's like being disproportionately powerful? if the astronaut had grown up in the moon's gravity his musculoskeletal system would be no where near as relatively strong.

In other words, the original superpower. Literally, that was the original Superman's premise: his species came from a higher gravity planet, so he was stronger in the much weaker Earth gravity. That's why he could "leap tall buildings in a single bound:" an odd flex for a being who could also fly around the planet fast enough to reverse time, but the first version couldn't do that, just leap. (See also: John Carter of Mars.)

 

[Foster Zygote]

So Vixen is talking about satellites at an altitude of 0km?

An uncle of mine had one of those.

 

[theprestige]

An Apollo astronaut weighing 180lbs carrying 180lbs on his back (ratio 1:1) on Earth, carries exactly that same ratio on the Moon, for the umpty-ninth time.

Yeah, but his muscle strength doesn't scale down as well. So he's now dealing with lunar weight for both his body and his backpack, but still enjoying Terran strength to deal with it.

 

[catsmate]

No, that is not so.

Untrue.

Why do you think it is?

Possibly because others have greater knowledge of how gravity works compared to you?

It'll be interesting when the Chinese team do their Moon Walk, in the near future, and compare and contrast with Apollo 11. There is no reason AFAICS why they shouldn't walk pretty much as normal (bearing in mind the effects of their 250,000 mile journey to get there).

No Kubrick wires to hoist them up *

Childish conspiratorial nonsense.

 

[Foster Zygote]

Er, by the same criteria, what do you think happens to a man who weighs 180lbs on earth?

Clue: the ratio to back pack remains identical, in other words.

⚠⚠⚠CLUE⚠⚠⚠: The ratio of his weight to the moon has ◊◊◊◊ all to do with his muscle strength. Unless he's been living on the moon for years, he'll still be able to exert the same force with his muscles as he did a few days earlier on earth. His muscles don't suddenly become 1/6th the mass they had on earth.

Damn, I've run out of popcorn.

 

[catsmate]

If you are now the equivalent of 30lbs, no it would not.

Utterly wrong.

 

[Foster Zygote]

Er, and so does a human being.

Oh, dearie me! You aren't laboring under the misapprehension that people on the moon get over 83% smaller?

 

[Foster Zygote]

Damn, I've run out of popcorn.

I've moved well beyond popcorn.

 

[Foster Zygote]

No, that is not so. Why do you think that is so?

Because he actually knows something about physics?

At this rate, I'm going to enter the pool with a prediction that your next big conspiracy theory thread will he you defending the flat earth cosmology.

Get yourself up to date! Flat earth is so 2025!

Vixen, take us on your Time Cube journey.

 

[Reformed Offlian]

*Looks up at the moon between fingers*. More than that, I'd say.

 

[Mojo]

The ratio remains the same, the ease of carrying it doesn't.

The one difference being that as the mass remains the same, everything has the same inertia/momentum as on Earth, and the contrast of that with the reduced weight can make changing direction or stopping a bit tricky. I seem to remember footage of at least one of the Apollo moon walkers being caught out by that.

Yes, you can see it in the video and the astronauts talked about it in their debrief. Your momentum remains the same, since that's irrespective of gravity. But your gripping force on the surface is diminished because that's a factor of weight times friction. Stopping and turning require gripping.

Ironically there was a balance problem, but it had nothing to do with the backpack weight. The human vestibular system is tuned to the rotation rates consistent with Earth gravity. The point at which your autonomic nervous system kicks in—when you suddenly (and sometimes viscerally) realize you're off-balance—depends on you starting to topple at a certain rate. That rate is determined by gravity. It turns out the astronauts didn't realize they were off-balance until far later into the topple sequence because it took that much longer for the rotation rate to register in the inner ear.

You can achieve the same effect from drinking a moderate amount of alcohol or living for several decades.
