For one thing, we cannot, as yet, reach the velocities necessary to make Light Speed travel possible, and it is doubtful that we ever will. There are theories that suggest that it may be possible to "jump" across vast distances of space by using some unknown technology of "hyper space" travel, or "warp".
These ideas are founded upon Albert Einstein's theory that space is curved. I believe this is ridiculous. Not that I can even begin to compare myself with the genius of that great man, but this particular idea of Curved Space is very much flawed. The idea of curved space comes from observations of the movement of light. It was noticed that a ray of light will alter its course when it passes near another object in space that has a gravitational pull. As light rays are assumed to always travel in straight lines, this bending of course seemed to indicate that space itself was somehow curved around objects with a gravitational field about them. This is in error, I feel, as it completely neglects the reality that a ray of light is actually a beam of PHOTONS, which are particles of MATTER. Anyone involved with physics at all should know that any form of matter is affected by gravity. That light rays are actually made of matter is the real reason why they bend in slightly when passing near stars and planets. Space is not curved at all.
This makes any idea of hyper space travel, warp speed engines, and wormholes impossible. It is logical, I know, to assume that space and time are curved because everything moves in great circles throughout the known universe. It is only possible to contemplate travel through time and space if the whole line is seen as a huge circle, but this just isn't so. The only way to cross these vast distances is going to be striking out on a course and following it. There is no shortcut way around it. And considering that the very closest solar system to our own, Alpha Centari, is about four light years away, it is going to take a long time to get anywhere else beyond our system. Just ONE light year is equal to 5,869,713,600,000 miles. The speed of light is more than 91 thousand times faster than the speed of sound, which is about 735 miles per hour. Even traveling in a craft that could reach mach 100, or 100 times the speed of sound, it would still take over 36,440 years to reach our nearest neighbor in space. Considering we are not even close to building a craft that could do mach 100, and even if we could, it would be over 1800 generations later that our crew would reach their destination, we should just give the whole idea up.
If we want to go places, we should instead try to
figure out how to cross DIMENSIONS rather than space, for it is here that
we stand more chances of success, though it will not be without problems.
Crossing dimensions has a very difficult problem to overcome. This
is not the case if we get into smaller dimensions that are within our own
reality. Getting out of them is simply returning to the larger dimension
which is where we are. If we find a way to get into the larger dimensions
though, we might never be able to get back.Going into a lessor dimension
is simply getting smaller and arriving there. Coming back is getting
larger again and returning to this scale. It will be an easy step
up. Going to a larger dimension may be initially easier to do, but
getting back will require that we find the exact place in atom of that
reality to return to. As things move slower the larger they get,
and faster the smaller they get, and it is all in constant motion, we may
not ever be able to find the point to return to.
