so light is part of an electron, and part of an electrons weight, but there is some magical barriar at the speed of light that changes light to have no weight? Maybe it's the way you think of gravity that leads you to believe that only light has the power to travel at the limit of the universe. [/b]
Sou,
Light is not part of an electron. Light is made up of photons. Photons are the elementary particles from quantum mechanics that transmit certain forces in interactions between particles that interact through the transfer of those forces (by "certain forces" I mean the electromagnetic force and the weak nuclear force.)
If you remember your atomic model (the Bohr Atom), then you can visualize a nucleus surrounded by it's associated electron "cloud" (or orbits, depending on how long ago you were taught about this.) Electrons in the atom are arranged in a series of "shells", or energy levels. Electrons in the outermost shell have the highest energy levels, in the innermost they have the lowest. If you take an atom and heat it up, electrons in the atom are what absorbs the energy. When an electron absorbs enough energy, it will dissappear from it's energy level, or shell, and re-appear instantaneously in the energy level that is appropriate for the amount of energy it has absorbed. The electron does not belong in this higher energy shell, it creates an instability in the energy balance of the atom. So the electron releases it's extra energy in the form of a photon, dissappears, and reappears instantly back in the lower energy shell. (Releasing a photon is the way that an electron loses the extra energy, an electron has only this option.) The released photon leaves the atom. The mass of the electron remains unchanged throughout this process. What I have described here explains the glow you see when you burn wood (gases associated with tree sap make the flames, plus just regular air that has been heated), or heat metal until it glows. This is the association that photons (light) have with electrons. Photons are also associated with many other particles, though, not just electrons.

After all you cannot use a lazer as a propulsion device, and I doubt you can use solar sails to catch light. [/b]
Your doubts notwithstanding, a solar sail has been successfully tested and shown to provide the necessary thrust.

Additionally, laser light has been shown to be sufficient to provide thrust to these types of sails. More info on this at these sites:

But what happens when you shoot two lazers so they cross paths? No light is bouncing off other light showing that light is a dormant energy untill it is absorbed by other matter.[/b]
Normally, in clean air, laser light is invisible. If there is dust in the air, you can see some of the light because it is scattered (bounced off, in your words) by the particles of dust. Not being an expert on these matters, I would guess that some forms of light could possibly be scattered by other forms of light, but I have not heard of this happening. If one were to do this type of scattering in clean air, all you would see is the area of intersection, the beams would be invisible elsewhere. Light is not "a dormant energy", whatever that means. Everything is energy if you examine it at the quantum level. Light is made up of photons. Photons carry energy.

gravity is space being bent? How can this be caused? [/b]
This is rather deep and I'm not going to go into it here. It difficult enough to understand it at all, much less explain it. But if you really, really want to know, have at it:

<div class='quotetop'>QUOTE(\"systemoftheuniverse\")</div>
Space is the void of matter, or the limit of how far matter's energies extend. But space is really how a expression of time (time in action). It has no form to bend. This is where it's important to know if God created matter by pulling nothing apart to create the two opposites of matter and anti-matter. [/b]
Space is
absolutely not the "void of matter". There is more space in you or me than matter.
What we call space is a construct of our minds. The universe is made of spacetime, not space, hence space is not an expression of time, space is a component of spacetime. What we call time is also such a component.
As to whether spacetime can be bent, I refer you to the two General Relativity links I posted above.
<div class='quotetop'>QUOTE(\"systemoftheuniverse\")</div>
But then the fact that space and time are able to be manipulated (when by all logic they should be constants) shows that even they come from nothing (a side effect of matter being created). That means that before there was anything except the soul, everything traveled at the speed of light, and there was no space.[/b]
Scientists are currently unable to describe the instant of the Big Bang. They certainly cannot describe any of the instants
before the Big Bang occurred. But I would venture to guess that, there being no spacetime to travel in, very few entities traveled at the speed of light since they had nowhere to go in the first place.
<div class='quotetop'>QUOTE(\"systemoftheuniverse\")</div>
Now when the universe was created from nothing... Matter was pulled from anti matter, and this had two measurable side effects, space/time (cause you cannot effect one without effecting the other) and then pressure, witch is the main element in effecting matter. Gravity is a force without a cause. Gravity is a force without it's equal and opposite side effect. [/b]
The creation of spacetime as a side effect of getting something from nothing is an interesting concept. After all, if you were to make matter and antimatter out of nothing, you would have to have someplace for them to be. Unfortunately, there has been no scientific description of the instant of the Big Bang as of yet, but M Theory could hold the answers.
