Human beings have evolved in a gravitational field which has remained constant in direction and magnitude since life began and for the most part, any connection between gravity and health was not even considered, however, the recent exploration into space and the subsequent interest in gravitational biology have revealed that even small changes in the gravitational field can have profound effects on human health.
Among the most important adverse health effects experienced by astronauts is the failure of the human immune system where immune cells, unable to mature, leave the astronauts exposed to all manner of illness.
A second example is that of bone cell growth, without a steady and constant gravitational field new bone cells will not become attached in their correct positions and will die which results in a continual loss of bone mass.
Of most importance to Hum Sufferers, are the effects on the receptors of the inner ear which allow humans to sense the direction and intensity of gravity.
Approximately half of all astronauts are affected by a series of unpleasant symptoms which include, nausea, headaches, loss of concentration and over-heating, that is, the same symptoms which have been reported by Hum Sufferers over many years.
Conclusion. Human beings have evolved in, and therefore need, a steady and precise gravitational field for the maintenance of good health.
Large parts of the Earth are now covered with a high voltage alternating grid that has modulated the gravitational field and a small proportion of people can detect this as a sound, in addition to this problem of a continuous irritating noise, many others experience the effects as ill health, both mental and physical.
Electrical energy is now the biggest form of pollution on the planet.
