Ordinary light from the sun is one, and the only one you can actually see. X-rays are another. Each kind, moving at a separate wavelength, has a unique effect on any matter it touches. When you lie out in the summer sun, for example, it's the infrared rays that ... of the oven, creating an electrical arc that may burn a hole in the oven. This hushed energy, electromagnetic radiation, flows all around us. All forms of matter, even your own body, produce electromagnetism -- microwaves, x-rays, untraviolet rays. It may interest you to know that whereas the human eye is sensitive to light radiation, the eye of the snake can sense infrared. Your body emits infrared radiation day and night ...
- 482: Astronomy And Space Science: Your Bones in Space
- ... gravitational and muscular strains on the skeletal system cause friction between bone crystals which creates bioelectrical fields. This bioelectrical effect in some way may stimulate bone cells and affect bone remodeling." In the early missions, X-ray densitometry was used to measure the weight-bearing bones pre & post flight. In the later Apollo, Skylab and Spacelab missions Photon absorptiometry (a more sensitive indicator of bone mineral content) was utilized. The results ... Medicine, raised a litter of mice on a animal centrifuge simulating 2G and compared them with a litter mates raised in 1G. "They were Herculean in their build, and unusually strong...." reported Dr.Graveline. Also X-ray studies showed the 2G mice to have a skeletal density to be far greater than their 1G litter mates.

A long, hard educational process is required during which a person must freely submit himself to a rigorous discipline, and strongly desire and believe in its outcome. Consequently, the truth follows that ...
- 485: The Case For The Existence of God
- ... at the speed of light (186,317.6 miles per second) it would take you 100,000 years to go across just the diameter of the galaxy. Light travels in one year approximately 5.87 x 1O.MDSU/12' miles. In 100,000 years, that would be 5.87 x 1O.MDSU/17' miles, or 587+ quadrillion miles. Our nearest neighboring galaxy is the Andromeda galaxy, which is an estimated 2,000,000 light years away. That's so far that a radio wave which ...
