The Truth Behind Moon’s Gravity. The Hammer and Feather Drop Experiment

With this short writing we  start a series under the title The Truth Behind in which we want to demonstrate the truth behind some of the scientific predictions. In this first writing we are going to demonstrate – via the Hammer and Feather Drop Experiment – that Moon’s gravity is far greater than predicted.Until now Moon’s gravity has been nothing but a calculated result of a theory never really proven by measures of experiments on another celestial body. Based on the theory and Moon’s theoretical measures (diameter, density) its gravity has been theorised as one sixth (approximately 17%) of Earth’s gravity.

Many people watched the short NASA video showing Apollo 15 commander David Scott dropping a hammer and a falcon feather together on the Moon. This act is an important scientific experiment proving that Galileo was right. The two objects hit the surface simultaneously as he predicted. So far so good, theory is proven. But the truth is you do not have to go to the Moon just to prove it. It can be easily demonstrated here on Earth in a vacuum chamber.

But again there is far more to this experiment than meets the eye! It is also a really important gravity experiment that has never been performed before on a celestial body outside Earth! And this is far more important than proving Galileo’s theory because it gives everybody the opportunity to measure Moon’s gravity compared to Earth’s gravity. Let’s see, how.

Here on Earth we can experience the pull of gravity in two phenomena. First here is the weight of objects lying at the surface. Second we can see objects falling towards the surface at an increasing speed. And that is what we can see on the video: two objects falling toward the surface of the Moon. The acceleration (gravity pull) is characteristic to the particular celestial body and it can be measured by measuring the time of the drop of an object from a fixed height. That’s what we are going to do.

Here on Earth an object dropped covers the firs meter of the fall about half a second (0.47 sec) and in one second it falls approximately five meters because of the acceleration caused by gravity on falling bodies.

In the preliminary science report Joe Allen says the following on the circumstances of the experiment:

“During the final minutes of the third extravehicular activity, a short demonstration experiment was conducted. A heavy object (a 1.32-kg aluminum geological hammer) and a light object (a 0.03-kg falcon feather) were released simultaneously from approximately the same height (approximately 1.6 m) and were allowed to fall to the surface. Within the accuracy of the simultaneous release, the objects were observed to undergo the same acceleration and strike the lunar surface simultaneously, which was a result predicted by well-established theory, but a result nonetheless reassuring considering both the number of viewers that witnessed the experiment and the fact that the homeward journey was based critically on the validity of the particular theory being tested.”

So the hammer on the video falls 1.6 meter before striking the surface. On Earth it would take 0.57 second and on the Moon’ – according to the accepted theory – it should take 1.41 second to fall this distance. Now we have all the data needed to perform our own experiment and measure the time of the drop on the video with a stop-watch.

To do it, we must open the video, which is available on the following sites:  http://teachertube.com/viewVideo.php?video_id=41342&title=Hammer_and_Feather_Drop_on_Moon, or http://www.youtube.com/watch?v=5C5_dOEyAfk, or http://www.youtube.com/watch?v=KDp1tiUsZw8, or at NASA sites http://nssdc.gsfc.nasa.gov/planetary/lunar/apollo_15_feather_drop.html and http://www.hq.nasa.gov/alsj/a15/video15.html.

And here comes the big surprise. No matter how many times we measure the time of the drop the reading will always be approximately 0.9 second instead of the predicted 1.41 second. That’s a big difference!

Let’s see the consequences of the experiment to the theory. Now we have strong evidence in hand that the theory is faulty. The accepted scientific theory on gravitation is not proven by the experiment, on the contrary. Moon’s gravity is not 17% of Earth’s gravity as predicted but approximately 40%, which is 2.5 times stronger. It means the Moon is either bigger or denser than thought (or both), or gravity is not constant and does not work the way scientists thought!

That is the truth behind Moon’s gravity and behind the Hammer and Feather Drop Experiment.

Of course our experiment will show the truth only IF men really travelled to the Moon in the Apollo Programme, and IF the drop experiment has been performed on the surface of the Moon, and IF the video has been taken on the Moon, and IF the video has not been tampered with! We just do not know! If it is a hoax….
