Humans Will Hear from Intelligent Aliens This Century, Physicist Says

Feb 26, 2018

By Jeanna Bryner

Humans will make contact with aliens by the end of the century, theoretical physicist and futurist Michio Kaku told Redditers last week. However, Kaku said he wasn’t sure whether we’d be able to communicate directly with this unknown extraterrestrial society — one that could run the gamut from hostile to pacifist, according to Kaku.

In his AMA on Reddit, Kaku responded to a question about alien civilizations, saying, “Let me stick my neck out. I personally feel that within this century, we will make contact with an alien civilization, by listening in on their radio communications. But talking to them will be difficult, since they could be tens of light years away. 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.”

Kaku 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.”

  • @OP – Kaku added,
    “Another possibility is that they land on the White House lawn and announce their existence.

    It does seem rather unlikely given the rare incidence of Earth-type planets, and the scale of the universe and the galaxies!

    But I think that is unlikely, since we would be like forest animals to them, i.e. not worth communicating with.”

    They would definitely conclude they had landed among primitive animals with no useful information to communicate, if they took the White House as a typical sample of the human population! –
    (For a slightly more intelligent sample, better try the Bronx zoo! )

    Kaku’s a perennial idiot. Like an advanced civilisation is going to use radio to talk to itself and its outposts…

    He says stupid stuff to attract attention.

    He is a physicist, – but he does have help with his thinking from a god-delusion! 🙂

    If they had tuned in to any of Donald Trump’s utterances, I think they would be almost incapacitated by their equivalent of rolling on the floor laughing their asses off.

  • Kaku says they need stereovision to hunt prey. Larry Niven came up with the puppeteers for his known space series. They were a prey species. While vertebrate predators seem to be brighter on Earth, I wonder if that would be universal.
