May the light and the noise to attract the aliens?

Since the advent of artificial lighting in the 19th century the mankind did not often think about the consequences. But our houses and streets illuminated constantly. And all so we could go about their business at any time of the day. Besides the obvious advantages for each of us and the economy, in society there is a growing understanding of the negative impact of artificial lighting. Light pollution leads to disruption of wildlife behavior, and also affects mental health. But we rarely think that's what the light on the vastness of space. Remember the night pictures of Earth from the ISS? Such a pretty girl could attract attention to himself.

Intelligent life in space exists?

We don't know if aliens existed. about which we wrote earlier, so far no one has decided. Scientists can only assume that life outside our planet exists. However, in the opinion of the eminent theoretical physicist Stephen Hawking, if intelligent life exists in space, we don't have to meet her and especially to attract attention.

To Share their thoughts about how friendly are the aliens .

Think about it: stumbled on an anthill, you will be talking with these insects? Most likely, you just step on an anthill and then shake the shoes. As you know, according to Hawking, our planet — an anthill. So if you stick to the same opinion adhered to this great scientist, we really makes sense to worry about what someone might see us. Or to hear.

Us who can hear?

In 1974, radio astronomer Frank Drake with the help of the most powerful in those years of the radio telescope at Arecibo Observatory sent into space and the messages that announced our existence. And in 1977 was sent into space in "Voyager-1 and Voyager-2". Aboard each spacecraft is a Golden plate, which in addition to basic information about us, are the coordinates of our planet.

Despite the fact that space exploration is our greatest achievement, some scientists still agree with Hawking. We don't know what could be aliens. And if there is a technically advanced civilization, it's very possible that we do not want to send messages into space that we are looking forward to meeting you.

However, without sending into space a message and we could inadvertently give away your presence. All because of the invention of radio communications, including navigation, television broadcasts, and . All these signals can be detected from space. So it is possible that we have already noticed. The question is, how friendly this "someone".

watching us?

As we have said, night shots of our planet from space are fascinating. The contours of the continents framed by the light, ships "paint" lines across the oceans, and the sea dotted with oil platforms. Despite the fact that even from our planet Jupiter seems to "pale blue dot" artificial lighting is clearly visible for technically advanced civilizations.

In the near future, space agencies of different countries can develop a means of detecting such artificial light from planets near other stars. However, if the aliens think that it is better not to take risks, we can fail. On the other hand, does not exclude the possibility that our planet is already headed alien guests. In this case, the question arises — should we dim the lights until it was too late?
