World-Renowned Physicist: The Truth About Aliens! UFOs Are Definitely Robotic - Michio Kaku
"If I were to shoot in the dark, I'd say first of all, they're robotic. They're not organic at all. These flying saucers can zigzag. They can dive from 70,000 feet all the way down. They can dive underwater. These require skills and tensions and vibrations that would crack any known US device in half."
Dr. Michio Kaku stated that observed UAPs performing extreme maneuvers are likely robotic rather than piloted by biological beings, as the forces involved would crush any known organic life. He suggested that if alien visitors exist, they deployed autonomous probes rather than risking biological crews, which would explain why they haven't made direct contact despite alleged sightings dating back millennia.

About this episode

In this wide-ranging conversation, host Steven Bartlett interviews legendary theoretical physicist Dr. Michio Kaku, co-founder of string field theory and author of multiple books on the physics of the future. The episode centers on humanity's biggest unanswered questions: where we came from, whether we're alone in the universe, and what the future holds as transformative technologies reshape civilization. Kaku, who has spent 71 years studying physics since age eight, opens by explaining string theory—his life's work attempting to complete Einstein's dream of a unified theory of everything. He describes the universe as originating from a Big Bang roughly 14 billion years ago, potentially part of a "bubble bath" multiverse where countless universes coexist in 11-dimensional space. Addressing recent declassified UFO files released by President Trump, Kaku states he found no smoking gun evidence but remains open-minded, theorizing that any visiting craft would likely be robotic rather than biological given the extreme forces involved. He warns that quantum computers pose an existential threat to digital security and could crack Bitcoin and all known encryption within decades, prompting urgent CIA concern. On artificial intelligence, Kaku predicts menial jobs will vanish but argues true creativity remains beyond current AI capabilities, though he advocates for humans merging with machines to remain competitive. He reveals that scientists have identified telomeres and telomerase as the keys to potential human immortality, but the same mechanism is exploited by cancer cells. Throughout, Kaku reflects on how his two years in the U.S. Army during the Vietnam War era fundamentally changed his worldview, teaching him that morality and meaning are not universal but constructed by individuals and cultures. He remains agnostic about God, viewing religion as evolutionary "glue" that holds intelligent societies together when pure reason fails.
