The book "Moongate:Suppressed findings of the U.S. Space program" by William L. Brian is centred on the position of the so called neutral point i.e. the point at which the gravitational pull of the moon equals the gravitational pull of the earth.

During the fifties the neutral point was quoted as being approximately 24,000 miles from the Moon. In July 1969 Werner von Braun stated that the neutral point was 43,495 miles from the Moon.

Brian claims that the neutral point distance has been used by NASA to cover-up the fact that the moon's gravity is greater than the one sixth of earths gravity. According to Brian if the neutral point is 43,495 miles from the Moon then the Moon's gravity would be 65% of that on Earth.

David Thatcher Childress in his book The Anti-Gravity Handbook" even suggests that if the gravity on the Moon is as large as Brian suggests, then NASA would have had to use ultra secret anti-gravity devices to carry out the moon landings. Captured alien technology, no doubt!

The above points can be dismissed by anyone with a small amount of Physics.

The graph below can be created on a spreadsheet with one formula.

• g = gravity (metres/second^2)
• G = The gravitation constant 6.67 EXP -11 (dimension-less)
• M = Mass of the Earth or Moon (kilograms)
• m = A mass of 1 kilogram
• r = distance from the centre of M (metres)
  

By plotting g at increasing distances starting with g as 1.62 for the Moon and 9.81 for the Earth the above curves are produced on a logarithmic scale.

The green line represents the gravitational pull of the Earth and the blue line represents that of the Moon. They cross at a neutral point (Point One) approximately 37,500 kilometres (24,000 miles) from the Moon, precisely the early figure quoted by scientists. The red line however shows the Earth's and Moon's gravity acting together. As you can see this shifts the neutral point (Point Two) to 71,900 kilometres (43,000 miles) from the Moon.

Therefore the graph shows that using the same values of g for the Earth and Moon we can get two very different answers for the location of the neutral point depending on the way you look at the results.

Sorry guys, no cover-up and no anti-gravity devices!
