In what was probably the most outstanding show on television, the history channel had a broadcast of alien engineering. If you missed this then you will always have certain questions of how these crafts maneuver the way they do.

            This was probably the most interesting information that ever has been provided. I will do a general summery of what the technology was about. Remember this is general summery and not a verbatim of the episode. If you want to learn more it is recommended you watch the History Channel’s Alien Engineering.

            First I want someone to show me a law of physics that prevents contact with a species millions of years ahead of us. Truth be told there is nothing that even remotely prevents it. There is no law of physics that prevents a species more advanced making contact with us.

            If you go back in history, Albert Einstein revealed a lot about how the universe works. In order to understand alien technology we must first refer back to the man that brought to light the theory of relativity. Albert Einstein revealed the basics of his theory of relativity the most common formula was: (E=MC2) He revealed the space was a vast mass and that the heavier the object was it would bend space.

            The theory of relativity, or simply relativity, refers specifically to two theories of Albert Einstein: special relativity and general relativity. However, "relativity" can also refer to Galilean relativity.

The term "theory of relativity" was coined by Max Planck in 1908 to emphasize how special relativity (and later, general relativity) uses the principle of relativity.

            Special relativity is a theory of the structure of spacetime. It was introduced in Albert Einstein's 1905 paper "On the Electrodynamics of Moving Bodies". Special relativity is based on two postulates which are contradictory in classical mechanics:

   1. The laws of physics are the same for all observers in uniform motion relative to one another (Galileo's principle of relativity),

   2. The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the source of the light.

The resultant theory has many surprising consequences. Some of these are:

v     Time dilation: Moving clocks are measured to tick more slowly than an observer's "stationary" clock.

    * Length contraction: Objects are measured to be shortened in the direction that they are moving with respect to the observer.

    * Relativity of simultaneity: two events that appear simultaneous to an observer A will not be simultaneous to an observer B if B is moving with respect to A.

    * Mass-energy equivalence: E = mc2, energy and mass are equivalent and transmutable.

            In brief, a spaceship in space would have their clock tick more slowly than our clocks here on the stationary planet earth. The brief summery is time is a gooey substance that can be manipulated, and the results are science fact this is something that is proven day after day in physic labs all over the country. Weight is also a factor, with the mass that is heavier and larger it would bend space and the lighter objects would spiral around it. Remember there is a vacuum in space and there is no density like here on earth.

            Understanding this we can get a clearer picture of space travel and density. With this theo
