The question of whether alien life exists or not has been debated, pondered and experimented upon for decades. People have been trying to find a sign or a signal that will indicate life beyond our planet. Now, a Harvard professor believes we might be receiving a signal that may prove that aliens do exist.

In Canada, researchers discovered a very powerful radio signal that they believe could be coming from another distant galaxy. This signal seems to repeat itself every 16 days. A Harvard professor, who is the chair of the Harvard Astronomy Department, believes that this signal could be a sign of an alien civilization. However, he does acknowledge that signals could also be generated through young neutron stars or another phenomenon that is not familiar to us yet. The signal is called a fast radio bust or FBR.

He believes that a possibility could be that alien life could be using a beam of energy to transport something within space. The signal that is being received by the Canadian researchers is the energy or radiation that is being leaked from that. However, the amount of energy needed for such a beam would be equivalent to the energy needed to sustain Earth, which seems unlikely.

The Canadian researchers do not seem to have the same point of view as the Harvard researchers and have said that non-professionals claim it as extraterrestrial life when they do not believe so. However, the Harvard professor is insistent that it is a possibility that needs to be considered and should be looked into with detail, with regards to possible natural causes and phenomena.

If we think about how our lives will change if alien contact is made, the thought itself is staggering. When the news of this signal spread, some people began to express their worry and fear while others wanted to know more. Scientists believe that actual contact with such life are close to impossible, because traveling in space is too difficult for them to come to Earth, or for humans to meet them where they are situated.

At times, such news may show some signs of extraterrestrial life and may have researchers excited for what they may discover; however, there has never been any substantial proof of whether life exists beyond Earth.
