Aliens might be following a strategic plan when it comes to visiting and contacting Earth, a new study suggests. According to the authors of the study, it is possible that the aliens are waiting for Earth to get closer to their home planet before initiating contact.

The new study, which was published in the Astrophysical Journal, serves as a response to the Fermi Paradox, a concept presented by physicist Enrico Fermi regarding the existence of extraterrestrial intelligence.

Basically, Fermi noted that due to the number of planets and stars in the galaxy, there should be another world teeming with intelligent extraterrestrial life. If this is true, then Earth should have already been visited or at least contacted by aliens.

However, since humans have not yet come across evidence of intelligent extraterrestrial life, many doubt the existence of alien civilizations. Recently, a team of scientists presented a new idea regarding the possible existence of extraterrestrial life.

In their study, the scientists noted that it is possible that alien civilizations are thriving in other planets in the galaxy. According to the scientists, these aliens have not yet visited Earth because they are still waiting for the right moment to do so.

They explained that this concept is based on the fact that the objects within the galaxy move constantly. In addition to planets and stars orbiting one another, entire solar systems are also known to travel around the centers of galaxies.

For lead researcher Jonathan Carroll-Nellenback, it is possible that the aliens from another planet are waiting for the time when Earth or the Solar System gets closer to their homeworld before sending out a probe or launching an expedition.

“If long enough is a billion years, well then that's one solution to the Fermi paradox,” Carroll-Nellenback told Business Insider. “Habitable worlds are so rare that you have to wait longer than any civilization is expected to last before another one comes in range.”

“Every system could be habitable and could be settled, but they wouldn't visit us because they're not close enough,” he added.
