Aliens or experts who have been to earth say aliens are traveling across galaxies

When mankind has been trying to explore alien civilization, the Milky way may have been full of interstellar alien civilization, but we don't know it. According to Fox News on September 10, a new study published in the Journal of astronomy claims that aliens may have explored the Milky way and visited the earth long ago.

The article also points out that aliens may be taking time to fully explore the Milky way and make it easier to 'travel across galaxies' (Star jumping) by using the motion of the star system. The new study claims that aliens may just be calmly and strategically waiting for the opportunity to visit earth.

When aliens visit earth

Humans may not have begun to evolve

This research work is the latest response to the Fermi paradox, which was first developed by physicist Enrico middot; Fermi asked the question: 'why haven't we found any signs of extraterrestrial life?' Fermi once questioned the feasibility of interstellar travel. Since then, his doubts represent doubts about whether there is really alien life.

Astrophysicist Michael & middot; Hart formally discussed this problem in a paper in 1975. He pointed out in his paper that in the 13.6 billion years since the formation of the Milky way, there has been enough time for intelligent life to settle in the Milky way, but we have never heard any news. Hart concluded that there must be no other advanced civilization in the galaxy.

This latest study provides a different perspective. Researchers believe that maybe aliens are just exploring slowly and calmly.

'if you don't consider the motion of stars when trying to solve this problem, you basically have only two answers,' Jonathan & middot, a computational scientist and the first author of the study; Carol nellenbach told business insider news. " Either no one left their planet, or we are actually the only technological civilization in the galaxy. "

According to business insider, many previous studies have failed to take into account the key fact that galaxies are always moving. Just as planets orbit stars, stellar systems orbit the center of galaxies. For example, our solar system orbits galaxies every 230 million years.

Stars and their surrounding planets orbit around the center of the Milky Way galaxy at different speeds and unique orbits. Sometimes they pass each other at a fast speed. Carol nerenbach's research suggests that aliens may just wait for stars to move and wait until their next destination is closer to them.

In this case, the time for civilization to spread to all planets will be much longer than estimated in Hart's study. So aliens may not have reached our planet, or when they visit the earth, humans have not yet begun to evolve.

"If this period of time is long enough to be 1 billion years, then this is an answer to the Fermi paradox," said Carol nerenbach Habitable planets are so rare that you have to wait longer than any civilization expects before another civilization comes into your view. "

The Milky way may be full of settled planets

In order to explore the possible existence of aliens, the researchers used a numerical model to simulate the spread of a civilization in the Milky way. They assumed various possibilities for a civilization to approach a new galaxy, including the range and speed of interstellar probes and the launch speed of these probes.

However, there are some problems in establishing the propagation model of alien civilization in the Milky way, because only one data point can be studied, that is, the earth itself. So all existing predictions are based on human behavior. But even with such limitations, researchers still found that the Milky way may be full of settled star systems we don't know. This is still true when they make conservative estimates of the speed and frequency of alien star travel.

"Every galaxy may have settled planets, but they won't come to us because they're too far away," Carol nerenbach said

According to the business insider news report, so far, we have found about 4000 planets outside the solar system, but no life has been found. But there are at least 100 billion stars and more planets in the entire Milky way. A recent study by Pennsylvania State University estimated that there may be as many as 10 billion earth like planets in the Milky way.

Therefore, Carol nerenbach said that the so-called conclusion that there is no life on these planets is too one-sided, just like seeing that there are no dolphins in a sea area, saying that there are no dolphins in the whole ocean. " At present, the absence of life does not mean that we are lonely. This just means that habitable planets may be rare and difficult to reach. " He said.

In the next few years, with the construction of new telescopes and more exploration equipment into space, our ability to detect and observe other potentially habitable planets is expected to improve significantly. " Now, we urgently need some data points, 'Carol nellenbach said.
