Beschreibung

We’re looking in all the wrong ways for intelligent life in space, but, what if we found it? Would they be friendly? Would they give us all the magic they have learned to perform? Would they enrich our lives? Even if they just said hello and let’s be friends, what would be the natural outcome of having them visit? Should we be looking for and calling for them to come here? Read this natural factual account of having neighbors from space visit us and how it will change our lives.

CHAPTER 1 MAGNETIC RADIO WAVES

Magnetic waves increase in strength as the square of the distance as we move closer to the source.

Magnetic waves diminish in strength as the square root of the distance as we move away from the source.

As a function of frequency, the clarity of the signal is dependant on the position it occupies on the magnetic spectrum. Light is a very high frequency and is therefore more discernible than sound, for instance.

The source of sound can be approximated from the signal, but the light is more easily pinpointed and becomes an image, such as a point of light. We don’t discern a “point of sound”.

Radio waves are much longer than light waves. They tend to scatter and become less focal than light.

We can do a radio direction detection and find a radio source, but until we get closer, it’s not as clear where the source is, exactly.

In a perfect universe, this is not a problem. The searcher can move in the approximate direction of the radio wave and the source becomes more and more defined as we approach.

This is not a perfect universe. It is filled with radio noise right down to and including the remains of the big bang.

With all of this radiated noise on a host of random frequencies, the diminishing radiated signals from Earth will shrink and be swallowed up in the background noise.

You can filter out the background noise and focus on the frequency of our radiated signals, that's true. It won’t be good enough to discern our radiated signals because the background random noise includes competing signals from so many other sources much closer to the direction finder.

Unless the extraterrestrials just happen to be passing by our stellar neighborhood and monitoring our relatively low frequency radio emissions, we are not likely to be found by our radio signature alone.

Besides, why would an intelligent race of extraterrestrials want to be looking at old episodes of “I Love Lucy” anyway? It could only reinforce their perception that our planet is devoid of intelligent life (only kidding).
