MYSTERIOUS DISCOVERIES ABOUT OUR PLANET

                                         Astronomers have discovered that they do not know what makes up over 90 percent of the universe. What is more, the discoveries that led to question their understanding of the fundamentals of physics itself. Of course, such questions are nothing new.           Toward the end of the 19 th century, physicists observed something odd about the speed of light. They found that relative to an observer, light always traveled at the same speed no matter how fast the observer was moving. But that seemed to defy natural law! The problem was addressed in 1905 in Albert Einstein’s special theory of relativity, which showed that distance [length], time, and mass are not absolutes. Then, after a flash of intuition that he termed “the happiest thought of my life,” Einstein began to develop his general theory of relativity, which he published in 1916. In this revolutionary work, Einstein wove gravity , space, and time together and refined the phys

WHAT YOU MUST KNOW ABOUT THE SUN

         The sun; a giant, glowing ball of gas some 850,000 miles in diameter . The temperature at its surface is over 11,000 F ., hot enough to vaporize any material known to man. Deep within the sun, the temperature rises to over twenty million degrees, a heat we cannot begin to imagine or comprehend.             The sun dominates our solar system, containing more than 99% of the system’s matter. The sun is a thousand times as massive as Jupiter, the largest planet, and 335 , 000 times as massive as the earth. And if the sun were hollow, 1,300,000 earths could be fitted inside!            In short, the sun is immense; it is the unquestioned center of the solar system.            And yet, when compared with other stars, the sun is nothing more than average. There are stars a dozen times as massive as the sun, and others but a tenth as large. There are stars that outshine our sun 50,000 times over, and others just a hundredth as bright.             In fact, the sun i

MYSTERIOUS DISCOVERY IN THE EYES

            Scientists have long known that the eyes of mammals contain neurons that respond to light and set the body’s internal, or circadian, clock. It was long assumed that this light-sensing function was performed by known visual cells called rods and cones. But in 1999, report the journal Science, researchers found that “mutant mice lacking all rods and cones [who are thus functionally blind] still have light-responsive clocks.” This led researchers to the conclusion that “some other cells in the eye had to be sensing light”            Now these elusive light sensors have been found. Although intermingled with the image-forming rods and cones, the sensors form “a separate visual circuit, running in parallel with this image-forming visual system,” explains Science. The newly discovered circuit’s functions include governing pupil size and melatonin release, synchronizing the body’s internal clock with the cycle of light and dark and other tasks. It may even play a role in

THE INVERTED RETINA

      The human eye contains a RETINA –a membrane with approximately 120 million cells called PHOTORECEPTORS, which absorb light rays and convert them into electric signals. Your brain interprets these signals as visual images. Evolutionists have contended that where the retina is placed in the eyes of vertebrates, creatures with a backbone, proves that the eye had no designer.       The retina of VERTEBRATES is inverted, placing the photoreceptors at the back of the retina. To reach them, light must pass through several layers of cells. According to evolutionary biologist Kenneth Miller, this arrangement SCATTERS the light, making our vision less detailed than it might be.        Evolutionists thus claim that the inverted retina is evidence of poor design –really, no design. One scientist even described it as a functionally stupid upside-down orientation. However, further research reveals that the photoreceptors of the inverted retina are ideally placed next to the pigment
