For a number of years, radio telescopes have been trying to pick up signals from outer space, so far without success. There are, however, millions of possible radio frequencies, and there is no reason why a completely alien civilisation should not use a different type of communication, such as X-rays, or even a type of wave we have not yet discovered. ………… . For example, if we made contact with beings 300-light years away - relatively close as space distances go - by the time we had sent an answer and received their response, the earth would be 600 years older.
The most famous radio telescope of all is at Jodrel Bank in England
We may have discovered only a few of countless types of waves that could be used in this way
And then there is the problem of how to carry out contact over such vast distances
According to Einstein’s Theory of Relativity, it is impossible to travel faster than the speed of light
Science fiction writers have been speculating over the nature of alien beings for decades
