KOMPAS.com – People continue to want to know if there is another life outside the Earth. Now, scientists have new ideas to steal the attention of our galactic neighbors.
They are planning to use laser technology, which today we have as flammable or "light planet verandas" for foreigners who could search us.
Scientists at the Massachusetts Institute of Technology (MIT) say that the light of the porch can be perceived not only around the world, but also 20,000 light years.
According to the team, infrared lasers can also be used to send basic reports to space. It serves as a Morse code to tell other animals about human existence on planet Earth.

"It will be a complicated project, but it's not impossible to do it," said James Clark, one of the researchers who participated in the study.
"Nowadays, lasers and telescopes can create detectable signals so that other creatures can see our stars and immediately see an unusual spectrum and will definitely pay even more attention," he said, quoted from Scientific anxietyWednesday (11/07/2018).
In the feasibility study, it is proposed to use 1-2 megawatt focused laser with a 30-45 meter telescope.
This will produce an infrared rays that are strong enough to defeat the energy generated by the sun and may therefore be strong enough to be perceived by the eyes of the aliens.
The most immediate possibility is that aliens in the Proxima Centauri region (the nearest star on Earth) or TRAPPIST-1 (a star that is potentially inhabited in 40 light years) can perceive the signal transmitted.

But the problem is that there is not enough telescope. At the same time, the laser should be burnt from the top to reduce atmospheric disturbance or the camera passing through this spacecraft.
"If we start communicating, we can send messages at speeds of around a few hundred bits per second to get there only a few years," Clarks said.
The new study also includes an analysis of whether laser-like beams from space can be perceived with instruments on Earth, although some experts argue that this is not possible because there will be too many obstacles that surround light.
It is not clear when this plan will be implemented. But at least, if people want to begin to "propagate" the existence of the Earth, we already know one direction.
"Overall it's a feasibility study. Whether it's a good idea or not, it will require more discussion later," said Clark.
