The Earth becomes invisible to the aliens

Suppose that there is extraterrestrial life, and that some form of life is looking exoterrestrial inhabited planets like ours.

Embark on a journey through space to reach them would be a stupid waste of resources, and therefore viable alternative, a radioactive signal tracking would be a much cheaper alternative to our intrepid friend extraplanetary capitalist.

So think Frank Drake, founder of the Search for Extra Terrestrial Intelligence (SETI) fifty years ago, and performs some thoughts (somewhat anthropocentric) about the possibilities that the aliens have to detect the planet earth.

Drake says that some years ago, when analog TV broadcasts, radio and radar were used everywhere, extraterrestrial life forms could be located with relative ease, since they surrounded the Earth 50 light years from radiation, generating television waves near one million watts.

However, times have changed, and now the satellites do not leak too much radiation, and things become more difficult for alien explorers.

"Now the actual amount of radiation that escapes is two watts Drake says, not much more than they need a cell phone.

If this continues in the future, our planet will soon become undetectable. "

Somehow Drake is guilty of anthropocentric to think that alien life forms would use the same tools as us to detect life in space, and both contain more technology than us.

Either way, it would be ridiculous to consider such speculation to continue to develop advances in telecommunications engineering.

Let's stay with the current technology.

And let's make it better.

Let aliens to do their own research with their own technology.
