[QUOTE="Harmon, post: 2682735, member: 24357"] [b]After a bit of research I am still confused[/b] I find it pretty strange, a guy with my level of education, with my level of reading comprehension, asking questions about the Speed of Light (SoL). [url]http://archive.ncsa.uiuc.edu/Cyberia/NumRel/EinsteinTest.html[/url] “The first prediction put to test was the apparent bending of light as it passes near a massive body. This effect was conclusively observed during the solar eclipse of 1919, when the Sun was silhouetted against the Hyades star cluster, for which the positions were well known. “Sir Arthur Eddington stationed himself on an island off the western coast of Africa and sent another group of British scientists to Brazil. Their measurements of several of the stars in the cluster showed that the light from these stars was indeed bent as it grazed the Sun, by the exact amount of Einstein's predictions. Einstein became a celebrity overnight when the results were announced. “The apparent displacement of light results from the warping of space in the vicinity of the massive object through which light travels. The light never changes course, but merely follows the curvature of space. Astronomers now refer to this displacement o f light as gravitational lensing. “But the Sun's gravity is relatively weak compared with what's out there in the depths of space. In the dramatic example of gravitational lensing below, the light from a quasar (a young, distant galaxy that emits prodigious amounts of radio energy) 8 billi on light years away is bent round by the gravity of a closer galaxy that's "only" 400 million light years distant from Earth.” Here is another site- this one has a drawing about light being bent by gravity, am I miss understanding what you guys are saying about light and its bend-ability or am I miss understanding these sites? [url]http://www.uh.edu/engines/epi1765.htm[/url] On the following site it kinda hits on something I was thinking about the exacts of the SoL. Heavier and lighter gravity areas in the universe would alter the speed of light. Am I reading this right? [url]http://www.grantchronicles.com/astro09.htm[/url] “In the next parallel universe our laws of gravity and light would not work due faster velocities for the gravity and light particles. So a missing piece of the puzzle is that the concentration of Dark Matter not only determines the speed of light in our part of the universe, but the behavior of returning gravity particles.” I really appreciate you guys taking the time to check out this thread. Personally I don’t think I understand this subject very well, but the logic of what I think and what I feel about it just seem so… well logical. If I have not said it in a while- thank you for your time on this, its really killer that you would try to help me out. Thanks. [/QUOTE]
