Light has mass and is effected by gravity. Light exsist as both a partical and a wave. There are theories that say that it is a possibility that the same may be true of gravity.
As far as faster than light travel....I think it is a possibility. However, I believe that it will be many many many years before we ever discover how to do it in this world.

--- Quote from: shibboleth ---My brain doesn't work well in science or math. But I do appreciate all those who have that gift. I have been to a number of Creation Science seminars and one thing that I find interesting about evolution is they never explain how an animal can survive in its transitory stages. In other words, how does a bird, that is turning into an alligator, live with a wing and a foot? what does this bizarre creature eat? It can't fly and it can't walk. I saw a picture of this creature and it just made me laugh that people can believe anything as long as it's not God.
I always liked the story about the emperor who had no clothes. It just shows how gullible people are and how willing they are to let the "experts" think for them.
I hope more of you science people can help us with some of these things.

Hi Debra, I remember reading a book a while back that disputed evolution and what the author termed "junk science" due to the fact that not one part of the theory could be proven in a lab setting.
He went on to say that when a frog turns into a prince in a flash, it is a fairy tale but if a frog turns into a prince through the muddy waters of billions of years it is science. The incalculable thought of billions of years is a bit much for the human mind to comprehend and has the power to confuse any scenario into being plausable.
Where in nature have we seen positive mutations, more commonly referred to as birth defects? When someone is born with an extra finger or something it generally does not function properly, also most of the birth defects are not transferable to the subsequent generations although there are cases of genetic transfer of some conditions or diseases being transferred to offspring, but these cases do not show an upward mobility or an improvement of the species.
We can also get into the 2nd Law of Thermodynamics or the Law of Entropy.........nah, that can wait.

Hello Joe,
Interesting question.
As an engineer in the scientific community I rely on the "Laws of Physics" or better stated "Cause and effect" to do my work. One of the basic precepts of physics is that matter cannot be created or destroyed, but only converted into energy. Gravity is a function of mass, the more the mass, the more the gravity. In order for any object to lose all gravity it would have to lose all mass. What your question proposes is that if an object would lose all gravity in an instant, how long would it take for the earth to feel the effect? If a large amount of the mass of the sun was instantly be converted into energy, which it does all the time by the way, and the sun exploded, the explosion would send chunks of mass scattering in all directions at some finite velocity less than the speed of light. The earth would then be essentially pulled in many directions simultaneously toward each of the sun fragments until all these pieces were so far away that they had no effect on the earth anymore. Of course this is all academic since if the sun blew up it would take the earth with it. The only way the sun could ever lose all its mass instantly is if God performed a miracle, which I define as sovereignly breaking the connection between cause and effect, and just spoke the sun out of existance.
I hope this helps a little, let me know if I can shed any more light on this (pun intended)

Joe,
In my previous post I made the statement that matter can be converted into energy. Although this can be observed in the macro world, it is not true in the micro world. In truth, in any process, mass in conserved and energy is conserved. What we observe is the conversion of one type of matter into another and the conversion of one type of energy into another, but there is still the same amount of mass as before as well as the same amount of energy.
Gravity is an interesting subject, and is being studied in depth by the scientific community with huge experiments. What is being searched for is the Graviton. Current theory is that gravity acts like a wave and travels at the speed of light.
