In this episode of The Michael Shermer Show, host Michael Shermer interviews Dr. Hakeem Oluseyi, astrophysicist and author of *Why Do We Exist? The Nine Realms of the Universe That Make You Possible*. Oluseyi shares his remarkable journey from a turbulent childhood in the Deep South to becoming a Stanford PhD and pioneering scientist, emphasizing the roles of hope, hustle, and serendipitous mentorship. He challenges conventional scientific thinking by arguing that we can now meaningfully ask 'why' questions about existence, not just 'how'. Drawing on cosmology, quantum physics, and the multiverse hypothesis, Oluseyi explains that time and space may have existed before the Big Bang through the inflaton field, and that the universe may be an infinite, self-replicating foam of bubble universes. He redefines fundamental concepts like gravity, time, and light, and offers a compelling explanation for the Fermi Paradox: while simple life may be ubiquitous, complex life—and especially advanced civilizations—are exceedingly rare due to Earth’s unique conditions, particularly the emergence of oxygenic photosynthesis. The conversation concludes with reflections on the future of space exploration, the limitations of government-funded science, and the transformative power of imagination in science and life.
Everything in the universe moves through spacetime at the speed of light, with motion through space and time being orthogonal—explaining gravity as a redirection of motion through time into motion through space.
The concept of 'time before time' is scientifically plausible via the inflaton field, which existed prior to our universe and imbued it with energy, making the idea of a 'first moment' nonsensical.
Life may be common in the universe, but multicellular life and advanced civilizations are extremely rare due to the specific conditions required—especially Earth’s unique oxygen-rich atmosphere created by photosynthesis.
The Fermi Paradox is resolved not by alien invisibility, but by the extreme rarity of advanced civilizations; there may be only 10 or fewer in our entire galaxy.
The universe is not a single 'Big Bang' event but a series of energy transfers across quantum fields—what Oluseyi calls the '10 Bangs'—each marking a phase transition in cosmic evolution.

The Speed of Light and the Nature of Time
“You're not being pulled down to Earth. You're moving through space time at the speed of light. But the Earth's surface is accelerating upwards. And so since force equals mass times acceleration, that is the force.”
The Time Before Time: Inflation and the Pre-Big Bang Universe
“There is a time before time. When I was a student in the 20th century, we were taught that's a nonsensical question, like asking what's north of the North Pole. But actually, the answer is right there.”
The Multiverse and the 10 Bangs of Cosmic Evolution
“You can start with the inflaton field... it puts energy into our space time, makes it rapidly expand. At the very end... energy goes out of that inflaton field into the quantum fields of matter and light.”
The Fermi Paradox and the Rarity of Advanced Civilizations
“Earth is the only place in the universe that we know of where fire can exist. Because what is so special about fire? Fire is this rapid reaction of oxygen combining with various other molecules.”
The Limits of Science and the Role of Imagination
Oluseyi critiques the current crisis in theoretical physics, particularly the stagnation of string theory, and argues that science needs more imagination and inclusivity. He champions the role of 'outsider insiders'—those with deep knowledge but outsider perspectives.
“You are a being of infinite complexity defined by relationships... You are possibility, curiosity, and change embodied, continually constructing and reconstructing yourself as you engage with the mysteries of existence.”
