Based on the supposed distance to the moon (hundreds of thousands of miles) the brightness on the moon should be MILLIONS of lux, brighter than anything ever experienced on earth. Please explain the manned moon missions and the surface of the moon appearing dark as night.

Bear with me here, but imagine the light source, the Sun, on the opposite side of a sphere as another object, the moon.

Holy crap. It appears larger. It's explained in mainstream as an optical illusion.

Bright gibbous moon tonight. Light brightness (lux) is quadratic to distance. If you half your distance to any light source (original or reflected) the light gets 4x brighter. The apparent brightness of the sun in the brightest part on earth in the brightest part of summer is around 120,000 lux. Based on the supposed distance to the moon (hundreds of thousands of miles) the brightness on the moon should be MILLIONS of lux, brighter than anything ever experienced on earth. Please explain the manned moon missions and the surface of the moon appearing dark as night.

If it were a theoretical point light source, that would be the case. In reality, the apparent size of the moon increases at the same rate, spreading out the increased brightness, so it would not appear any brighter.

How bright does the surface of earth look from an airplane at 35k feet? Is it millions of times brighter when you look at it from 2 feet? Obviously not, you fricking dolt.

They went to the light, earth-facing side.

Also do not Google shadow analysis Apollo 11. They 'debunk' moon hoax conspiracy by saying shadows could have only come from the sun not a studio light.

What light source created this shadow?

What in God's name. No, no, no. Light sources' apparent size increase and their intensity of brightness. Spreads out and doesn't get brighter? Holy shite. Are you trolling?

Yes. 0 lux x millions = 0. And you got it backwards. If the dirt had natural brightness (it doesn't) it would look brighter from the surface than from the airplane.

What? Are you saying that earth's surface reflects light at 0 lux?

And you got it backwards. If the dirt had natural brightness (it doesn't) it would like brighter from the surface than from the airplane.

No no no, you said yourself it doesn't matter if the light is original or reflected.

You read poorly and you're not smart. A light source that is reflected will be no different

Lets walk this through:

1. the highest lux readings at the earth's surface on the equator is 120,000 lux (filter through our atmosphere).

2. the sun produces this light approximately 94 million miles away

3. when the moon is reflecting light on the earth it is father away from the sun than the earth so slightly less light reaches the moon than the earth, prior to the filtration of the earth's atmosphere

4. given the fact the moon is less than a perfect reflector (roughly 7%) it, therefore, could never produce lux readings on earth's surface of more than 120,000 lux.


You continue to demonstrate you are nothing but a copy-paster with zero ability to think on your own.

Well, the parts of the earth that aren't black reflect some light during the day. It's not much. But it would get dimmer as you got further away. Your whole misunderstanding of that was so unreal. You are a moron.

You're just going to have to explain why the principle is different for light reflected from the surface of the moon and the surface of the earth.

What really happens is the same in either case. If you halve the distance to the moon, yes four times as much light will reach your eyes, but it will be sourced from an area that appears four times as large. As a result each point on the moon's surface appears the same brightness. The same is true of the surface of the earth from a plane. It appears a certain brightness from 35k feet, but as you descend it gets brighter but also apparently larger at the same rate. It will never blind you even as you put your eyeball 100,000 times closer to it.

This is easy to verify via experimentation, whether you are looking at light from the earth's surface, or the moon, or a wall. Now you have to explain why the light reflected from the moon would be different.

I love how you can see amazing constellations and light shows from the stars on Earth but go to the moon, you know closer to those things and the sky is nothing but pitch black.

Forget the fact that NASA itself admitted that they lost the footage of the original 1969 landing but don't worry, they've been restored with awesome effects.

Nothing shady about them using the original tapes to record over because of lack of funds.


Moon landing tapes got erased, NASA admits

Yup, they couldn't even agree.
