Earth is becoming invisible, aliens will have a hard time finding us.

Digitization of TV and radio is blamed.

It was during a meeting at the Royal Society in London, founder of SETI, Frank Drake, came with statements about how the recent years development has changed the ability of his potential colleagues on other planets to discover earth.

While the old analogue TV transmitters could rise to one million watts, todays signals, including satellite signals are transmitting as little as 20 watts.

- To the aliens who are listening for something, the digital TV signals just sounds like noise, said Drake. In other words, like when you have an old-fashioned FM radio between stations.

Whit the digitization of radio and TV signals we are about to erase the traces of our own existence.

- Continuing this, our world will soon be impossible to detect, "said Drake, who believes that our development shows why we still have not heard signals from other civilizations.

- Using ourselves as an example, it shows how much harder it becomes to find other civilizations, "said Drake.
