If man has ever truly been to the moon it has been done in secret and with a far different technology. The tremendous radiation encountered in the Van Allen Belt, solar radiation, cosmic radiation, temperature control, and many other problems connected with space travel prevent living organisms leaving our atmosphere with our known level of technology. Any intelligent high school student with a basic physics book can prove NASA faked the Apollo moon landings. If you doubt this please explain how the astronauts walked upon the moons surface enclosed in a space suit in full sunlight absorbing a minimum of 265 degrees of heat surrounded by a vacuum. NASA tells us the moon has no atmosphere and that the astronauts were surrounded by the vacuum of space.
Heat is defined as the vibration or movement of molecules within matter.
The faster the molecular motion the higher the temperature. The slower the molecular motion the colder the temperature. Absolute zero is that point where all molecular motion ceases. In order to have hot or cold molecules must be present. A vacuum is a condition of nothingness where there are no molecules.
