Sun's Rays Bouncing off objects vs. Global Warming
When the sun's rays strike the earth, we get light and heat. But the sun's rays don't disappear magically after that. They bounce off of and go back into space. There is an enormous amount of space junk out there, like satellites, for instance. If the sun's rays bounce off the earth, and onto the satellites, and back off of them, back to earth, and then back to space, etc. (And all the while, more rays from the sun are striking the earth) Couldn't this cause the sun to seem to have more intensity? Couldn't this heat the earth up more in some locations, especially areas influenced by greater quantities of spacejunk?
Or is it possible that the sun's rays are striking spacejunk and bouncing off of it in such a way as to concentrate it over some parts of the earth? The concept I am talking about can be easily illustrated by focusing the sun's rays through a magnifying glass, enough to set a piece of paper on fire.
What if there is NO global warming, but the hotter temperatures on the planet are actually from our "technology?" To admit that, would mean that we'd have to change, or end, the technology that is making lots of money for many right now. It would be easier to just blame the average citizen, and tax him/her for every breath they take. Now, that would make even more money for those in charge.
Has any research been done on this subject? I am thinking of doing some mini experiments myself. Any comments/suggestions? Thanks for your input.

That's doubtful, for two reasons:
1) There is no perfect reflector of light. For example, even in a best case scenario, the moon reradiates about 13.6% of sunlight that hits it, but that's in all directions, not just towards Earth. In fact, from the Earth's surface, the moon is only about 1/100,000th as bright as the sun.
2) The majority of the surface area on most satellites is taken up by solar panels, which by necessity are horrible reflectors of light (otherwise, if they were good reflectors, they couldn't absorb enough sunlight to get the necessary energy to power themselves).
3) The satellites we have in space are far too small to reflect that much light. On a good night, you might be able to see the ISS, the largest manmade object ever in space, but even then it's a small speck of light; it looks like an exceptionally bright star, or a plane at a very high altitude. So, b/c of the small surface area, any light that is reflected won't matter much. Even the debris-cluttered orbits around earth are relatively empty. -

Interesting idea. Solar energy comes to the earth in many different forms: UV, visible light, infrared, radio, etc..., but most of it is reflected as far infrared. A little energy is reflected as visible light. When infrared or even visible light strikes an object in orbit around the earth, it is most likely absorbed completely due to the low temperature of the object's exterior.
Technology IS actually responsible for warming on the earth, but in a different way. The large amounts of brick, concrete and especially asphalt in urbanized areas have caused localized warming in cities, since these materials absorb heat by day and radiate it at night.
Lastly, global temps have been shown to be cooling since at least 2001-mostly due to reduced solar activity. That in itself could be the subject of a major discussion.

There are different rays in space. I talked with scientists of Extraterestrial ray reseacrh instute in germany. When I was 12 years old I read an article about the rays and cosmic particles that shot into the helmets of the Apollo astronauts.
That was very impressive for my as a child. They made SEM cross section pictures from cosmic ray impact.
But I believe that the experts don´t even know all things and rays .
In 2005 I made UV light research of bull eyes pattern of flowers with a NIKON UV lens , which I lend from German space agency. The results were very exciting.
Noone can say : " I only believe , what I can see with my human eyes !" This is stupid ! We only see a part of spectrum of light and rays. Insects see more UV IR light.
Do you heared about a extinction shift theory ( of cosmic rays ) by a Christian creationist sceintist Dr Dowdye in USA ? This man is a genius !
