Probably the number one conspiracy theory is the picture of the flag waving on the moon when there is no atmosphere. There is a simple explanation: it was due to inertia of wiggling the flag post into the lunar surface and because the horizontal rod that runs along the top of the flag got stuck part way out. This meant that the flag didn't "unfurl" fully and is hanging like a curtain rather than being stretched flat as was the original intention. The rod was used because NASA knew that, with no atmosphere and hence no wind, a flag would just hang down.

The Apollo spacecraft passed through the inner belt in a matter of minutes and the outer belt in about 1 1⁄2 hours. The astronauts were shielded from the ionizing radiation by the aluminum hulls of the spacecraft. The inner belt is the more dangerous one, containing energetic protons.

The lunar land modules did scatter a lot of dust, but in the landing itself, the power was decreased for many technical reasons and because of the light gravity that is with the moon.
About a 10 minute video to explain and even visualize the landing.
The light from the sun hitting the surface of the moon is too bright for any camera to capture something in the distance -- it would wash out any light coming from distant stars in the sky. Just as it is harder to see stars from a city because of the lights than it is to them from out of the city. All the lunar missions were done during the daylight, which lasts 29 Earth days.
The Lunar Modules used Aerozine 50 (fuel) and dinitrogen tetroxide (oxidizer) propellants, chosen for simplicity and reliability; they ignite hypergolically – upon contact – without the need for a spark. These propellants produce a nearly transparent exhaust.

ready for take off. The camera was on the lunar rover and controlled from earth.
There are satellites that orbit the moon and since the debris is too small to see from a telescope, the satellite images show evidence of the lunar landing and man`s foot prints on the lunar surface.
A great example of how to reply to a person that thinks the moon landing and other scientific advancements from NASA are fake.
A video that puts the nail in the coffin for the conspiracy theory that NASA faked the man moon landings
They still will not accept that we landed on the moon-----they will say it is a film made in Hollywood.

E = mc2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing. Under the right conditions, energy can become mass, and vice versa. We humans don't see them that way—how can a beam of light and a walnut, say, be different forms of the same thing?—but Nature does.
So why would you have to multiply the mass of that walnut by the speed of light to determine how much energy is bound up inside it? The reason is that whenever you convert part of a walnut or any other piece of matter to pure energy, the resulting energy is by definition moving at the speed of light. Pure energy is electromagnetic radiation—whether light or X-rays or whatever—and electromagnetic radiation travels at a constant speed of 300,000 km/sec (186,000 miles/sec).
Why, then, do you have to square the speed of light? It has to do with the nature of energy. When something is moving four times as fast as something else, it doesn't have four times the energy but rather 16 times the energy—in other words, that figure is squared. So the speed of light squared is the conversion factor that decides just how much energy lies within a walnut or any other chunk of matter. And because the speed of light squared is a huge number—90,000,000,000 (km/sec)2—the amount of energy bound up into even the smallest mass is truly mind-boggling.
Here's an example. If you could turn every one of the atoms in a paper clip into pure energy—leaving no mass whatsoever—the paper clip would yield 18 kilotons of TNT. That's roughly the size of the bomb that destroyed Hiroshima in 1945. On Earth, however, there is no practical way to convert a paper clip or any other object entirely to energy. It would require temperatures and pressures greater than those at the core of our sun.
It is a common misconception that seasons occur because of Earth's elliptical orbit around the Sun, with winter occurring when Earth is farthest away from the Sun, and summer when it is closest to it.
However, our planet's distance from the Sun has little effect on the onset of seasons. In fact, Earth is closest to the Sun, or at its Perihelion, around the Northern Hemisphere's winter solstice, while it is farthest away from the Sun, or at its Aphelion, around the north's summer solstice
