Japanese-American theoretical physicist Michio Kaku advocated for the scientific basis of multiverses and addressed the search for extraterrestrial intelligence. Kaku stated that humanity is still at the “Type 0 civilization” level and that civilizations encountered in the future could be tens of thousands of years more advanced than us.
Referring to unidentified aerial phenomena (UAP) and military radar records that have emerged in recent years, Kaku said, “The maneuvers of these objects are too unusual to be explained by classical aerodynamics and the laws of physics.”
In his 70-minute video, released last month and garnering great interest, Japanese-American theoretical physicist Michio Kaku made striking statements regarding the simulation hypothesis, multiverses, and the search for extraterrestrial intelligence.
Addressing a philosophical and scientific debate, Kaku referred to Nick Bostrom's simulation argument and the discussion popularized by 'The Matrix' film, emphasizing his skepticism towards this idea. Kaku stated:
“The computational power required to model all quantum states and atomic interactions of the universe is unimaginably vast. Quantum mechanics is probabilistic by nature. Modeling all possible states of a system simultaneously would require an astronomically large dataset. Therefore, the view that the universe is a simulation in its entirety is, to me, more of a philosophical speculation.”
The concept of multiverses has a scientific basis
In contrast, Kaku, who argued that the concept of multiverses has a scientific basis, proposed that quantum mechanics' superposition principle allows particles to exist in multiple states simultaneously, and the act of observation can 'collapse' these possibilities into a definite outcome. Noting that, according to Everett's many-worlds interpretation, the universe branches with every measurement, and every possible outcome occurs in a different universe, Kaku said, “String theory also allows for different vacuum solutions, and each solution can represent a different physical universe.”
Kaku reminded that the idea of multiverses has generated significant interest not only in theoretical physics but also in popular culture through the Marvel Cinematic Universe or Oscar-winning films, noting that, according to him, this interest is a reflection of humanity's tendency to question its perception of reality and consider alternative possibilities.
Evaluating the simulation hypothesis within a metaphorical framework, Kaku concluded that multiverses are a physically investigable phenomenon, emphasizing that more precise cosmological measurements in the future, especially anomalies in the cosmic microwave background, could offer indirect traces of multiverses.

The search for extraterrestrial intelligence and civilizations on a cosmic scale
Theoretical physicist Michio Kaku addressed perhaps one of the most fundamental questions about humanity's place in the universe, asking, "Are we alone?" Kaku first defined the concept of intelligence, stating that it is not limited to human intelligence but can manifest in different forms in nature. Kaku provided examples of studies on measuring animal intelligence, particularly the analysis of communication systems of dolphins and other social animals with AI-supported methods.
Humanity is still largely dependent on fossil fuels
Expanding this approach to a cosmic scale, Kaku introduced the Kardashev scale, stating that this scale classifies civilizations according to their energy consumption capacity. Kaku said:
“Type I civilizations control all energy on their planet, Type II civilizations can harness the energy of their star, and Type III civilizations can manage energy on a galactic scale. Humanity is still at Type 0 level and is largely dependent on fossil fuels. This finding indicates that human civilization is still at the initial stage of its developmental journey.”
The search for extraterrestrial intelligence should now be more systematic and data-driven
Referring to unidentified aerial phenomena (UAP) and military radar records that have emerged in recent years, Kaku stated, “The maneuvers of these objects are too unusual to be explained by classical aerodynamics and the laws of physics.”
Kaku stated that most of these observations could be explained by natural phenomena or human-made vehicles, but a small remaining portion might point to unknown physical processes.
Kaku also expressed that this situation indicates that the search for extraterrestrial intelligence should now be more systematic and data-driven, emphasizing that the burden of proof now rests with those who wish to demonstrate that these phenomena have ordinary explanations. Kaku added that civilizations encountered in the future could be tens of thousands of years more advanced than humanity, which would lead humanity to re-evaluate its role in the universe.
