Humans Will Come Into Contact With Aliens Within This Century, Predicts Expert

According to theorist physicist and futurist Michio Kaku, human beings are expected to make contact with aliens by the end of this century. However, the communication is expected to range from hostile to pacifist. It can also be not known if humans will be able to communicate with them directly or not. Kaku said that humans will be able make contact with the aliens by listening to their radio communications. However, actually talking to them will be difficult since they can be many light years away.


Kaku said, “So, in the meantime, we must decipher their language to understand their level of technology. Are they Type I, II, or III??? [These represent three categories in the Kardashev scale, measuring technological achievement in civilizations based on their level of energy use for communication.] And what are their intentions. Are they expansive and aggressive, or peaceful?” he added, “another possibility is that they land on the White House lawn and announce their existence. But I think that is unlikely, since we would be like forest animals to them, i.e. not worth communicating with.”

Futurists and theoretical physicists have come up with many ideas for when and how humans will be able to make contact with the extraterrestrials. An astronomer calculated that this can happen within 1500 years and another said humans might find the aliens by 2040. Many scientists have also warned about the risks which are involved in terms of interacting with aliens. Stephen Hawking said that the intelligent aliens would not resist from getting rid of the human race. A survey carried out recently suggested that humans will not be harmed by aliens.

Kaku was probably talking about the narrowband signals when he mentioned the radio communication. Or maybe those which are spread over a very small part of the radio extent of the electromagnetic spectrum. In response to a Reddit user who asked how much advanced an alien society might be morally and philosophically, Kaku said, “I get asked if the aliens are evil and want to destroy us. Maybe, but I think in the main they will be peaceful because they have had thousands of years to resolve sectarian, fundamentalist, nationalist questions. However, they still might be dangerous if they simply don’t care about us and we get in the way. In War of the Worlds, the aliens did not hate us. We were simply in the way. In the same way that a developer is a threat to forest animals because he can pave the first, the danger there is from someone who sees that we are just in the way. But for the most part, I think they will be peaceful, but view us like we view forest animals.”

In his book, “The Future of Humanity”, Kaku described the aliens based on interviews with the experts in exobiology. According to the description he gave, they are most likely to have three traits;

  • stereovision, which is needed to hunt
  • grasping appendages which are like opposable thumbs
  • their own different language(s)
