The “radio silence bubble” prevents us from making contact with aliens, scientists from the Federal Polytechnic School of Lausanne say. Their study, published in The Astronomical Journal, showed that the Earth is in a so-called “bubble” that prevents us from receiving messages emitted by alien vehicles.
The search for extraterrestrial life is one of the main topics that interests scientists from all over the world. However, as it turned out, the passage of waves encoded in the form of radio waves through the Milky Way can be difficult. Scientists have developed a mathematical model that allows us to describe this process and suggested that at any given time in the Milky Way there is at least one electromagnetic signal of technological origin.
“If the assumption of scientists is correct, then according to statistics, from one to five messages per century occur through our galaxy,” the study says.
However, due to the size of the Universe, the Earth is in a “bubble of radio silence” that prevents us from receiving these messages.
The most optimistic scenario assumes that we will receive a message from aliens no earlier than 60 years from now. At the same time, the least optimistic scenario suggests that we can wait more than two thousand years.
“This is a very interesting study that allows us to better understand why we have not yet made contact with other civilizations. However, we should not despair and continue to look for extraterrestrial life,” says astronomy expert John Smith.
As the proverb says, “there is no evil without good.” Even if we cannot receive messages from alien civilizations right now, this does not mean that we will not find other ways to contact them in the future. Research in this area is ongoing, and perhaps we will soon find answers to all our questions.
