Did a little reading last night on FTL travel. Seems science is always ready to make adjustments to Einstein's
Theory of Relativity to account for objects able to exceed the speed of light when moving in space.
Just a small sampling of what is currently being discussed.
excerpt from: Wikipedia, the free encyclopedia (Redirected from Faster than light travel)
Light spots and shadows
If a laser is swept across a distant object, the spot of light can easily be made to move at a speed greater than c.[18] Similarly, a shadow projected onto a distant object can be made to move faster than c.[19] In neither case does any matter or information travel faster than light.
[edit] Closing speeds
An observer may conclude that two objects are moving faster than the speed of light relative to each other, by adding their velocities according to the principle of Galilean relativity.
For example, two fast-moving particles approaching each other from opposite sides of a particle accelerator will appear to be moving at slightly less than twice the speed of light, relative to each other, from the point of view of an observer standing at rest relative to the accelerator. This correctly reflects the rate at which the distance between the two particles is decreasing, from the observer's point of view and is called the closing speed. However, it is not the same as the velocity of one of the particles as would be measured by a hypothetical fast-moving observer travelling alongside the other particle. To obtain this, the calculation must be done according to the principle of special relativity. If the two particles are moving at velocities v and -v, or expressed in units of c, β and − β, where
then this relative velocity (again in units of the speed of light c) is
,
which is less than the speed of light.
[edit] Proper speeds
If a spaceship travels to a planet one light year (as measured in the Earth's rest frame) away from Earth at high speed, the time taken to reach that planet could be less than one year as measured by the traveller's clock (although it will always be more than one year as measured by a clock on Earth). The value obtained by dividing the distance travelled, as determined in the Earth's frame, by the time taken, measured by the traveller's clock, is known as a proper speed or a proper velocity. There is no limit on the value of a proper speed as a proper speed does not represent a speed measured in a single inertial frame. A light signal that left the Earth at the same time as the traveller would always get to the destination before the traveller.
[edit] Phase velocities above c
The phase velocity of an electromagnetic wave, when traveling through a medium, can routinely exceed c, the vacuum velocity of light. For example, this occurs in most glasses at X-ray frequencies[20]. However, the phase velocity of a wave corresponds to the propagation speed of a theoretical single-frequency (purely monochromatic) component of the wave at that frequency. Such a wave component must be infinite in extent and of constant amplitude (otherwise it is not truly monochromatic), and so cannot convey any information[21]. Thus a phase velocity above c does not imply the propagation of signals with a velocity above c.

Interesting stuff George.
I saw a program the other night, they showed that the hubble telescope is starting to return data of planets orbiting other stars in our galaxy. What they are looking for is a rocky planet in the right proximity to a star to support life forms. So far all they have found is a few stars which appear to have large gas cloud planets like Jupiter orbiting them.
They appear as small dark spots passing in front of the star.
So if what they are seeing they've identified correctly, God did make some other planets out there.

David,
You know; we start to understand when we know what we do not know. And we can only know what is
revealed to us or what our mind has the capacity to assimilate and adopt. In a short time many of us will
know much more about GOD'S Purpose for our being than we now know. I always have to revert to my
childhood days when someone adult said to stop asking questions; i said why stop if i want to learn. When
i got wiser (many cuffs in the head) :-X i stopped asking but kept looking and searching. Our FATHER IS Creating
us in HIS Image (Work in progress); as we grow our mental capacity to see and understand HIS Word grows.
Listening to Ray's teaching daily make me feel closer to GOD and farther from the things of the world. In his
Repentance teaching here is a quote from Ray (in blue below):
Excerpt from Repentance Nashville 2005
http://forums.bible-truths.com/index.php/topic,3709.msg27923.html#msg27923
So I was wanting to repent of everything. EVERYTHING. I didn’t want to hold on to anything! Give it all up. And in my heart and mind, I was able to do it. And I didn’t have to struggle! I mean, I struggled all my life against these sins and now I didn’t have to struggle anymore. The temptations would come up, but I would just put a stop on it. That was it; God put me in control. And I didn’t have to fight it night and day. It just started to take care of itself. Because there was a power working in my mind that I didn’t have before. It was now God’s time to do that.
And when I had nothing more to repent of, that I knew of, then the scriptures started opening up. I started understanding the scriptures that I never understood before. And I would learn something every month. Every week, and then almost every day! New things, spiritual things, lofty things. So, if the spirit of God is going to be between your ears (you understand your heart is in your brain…), when the spirit of God starts to motivate your mind then you have greater capacity. If you have a glass of water and you want to pour a coke into it, you’ve got to pour the water out, you’ve got to make room. And that’s what happens in your life when you make room for God.
