Jakarta –
In a recent study, studies revealed this alien only interested in making contact with technologically advanced planets, while the technology on Earth is not yet that advanced.
In a study published on arXiv, an astrophysicist at the Hebrew University of Jerusalem said that life has undergone many revolutions on other planets and galaxies. Therefore, aliens may be more interested in planets with advanced technology.
The aliens are making long distance space travel
On the page Live science described, the study explores the Fermi paradox. Well, this paradox posits that given the age of the universe, intelligent aliens are very likely to undertake long-distance space travel from now on.
In this way, it is possible for them to visit Earth. Previously, experts have argued that aliens may have visited Earth in the past, before humans evolved and were able to document these visits.
Another possibility is that long-distance space travel may be more difficult than previously thought. As a result, the journey becomes a challenge for the aliens to reach Earth.
On the other hand, it might as well alien deliberately decided not to explore the cosmos. However, in his new study, Wandel explains that life forms in the Milky Way galaxy are extremely common.
Aliens more interested in technological signs
Intelligent aliens are most likely more interested in technological cues. However, technological signals can be difficult to detect.
In fact, the Earth has been emitting detectable signals from space in the form of radio waves since the 1930s.
When viewed in theory, these signals wiped out some 15,000 stars and planets orbiting them. However, this is only a fraction of the 400 billion stars in the Milky Way galaxy.
It takes time to respond to alien messages
Wandel explains that it takes time for response messages from aliens to return to Earth. So only stars within 50 light-years have had time to respond since Earth began emitting signals beyond the planet.
Even though there are more than 100 million technological planets or intelligent civilizations in the Milky Way, it’s possible that Earth’s signal hasn’t reached the planet yet.
However, as time goes on, Earth is also emitting more and more radio waves, so it becomes more likely that Earth’s technological signals will find them. alien.
