In this episode of The Diary of a CEO, featuring Brian Keating and Steven Bartlett, Brian Keating: I’m Spending $200 Million To Explore Existence! How God Fits Into Science Explained! explores astrophysicist’s $200M Experiment Probes Universe’s Origin, God, and Us Astrophysicist Brian Keating explains how his career-long mission to understand the origin of the universe has led to a new $200 million observatory that may provide the first hard scientific clues about whether the cosmos had a singular beginning—implicating questions about God, creation, and meaning.
Astrophysicist’s $200M Experiment Probes Universe’s Origin, God, and Us
Astrophysicist Brian Keating explains how his career-long mission to understand the origin of the universe has led to a new $200 million observatory that may provide the first hard scientific clues about whether the cosmos had a singular beginning—implicating questions about God, creation, and meaning.
He recounts the rise and fall of his famous South Pole BICEP experiment, which briefly appeared to detect signatures of the Big Bang’s first moments before being disproven by galactic dust, and how that scientific failure reshaped his views on ambition, humility, and the Nobel Prize.
Keating and Steven Bartlett explore the tension between science and religion, agnosticism versus practice, and why Keating remains a devout, practicing Jew while insisting God can’t be proven or disproven by physics.
The conversation widens into the rarity of intelligent life, simulation theory, astrology, free will, and what gives life meaning, with Keating arguing that our likely cosmic loneliness heightens our responsibility to each other and to the fragile planet that made us possible.
Key Takeaways
The new $200M Simons Observatory could test whether the universe had a singular beginning.
Keating’s new Chilean observatory (funded heavily by Jim Simons) is designed to detect subtle patterns in the cosmic microwave background—specifically polarization signatures that would only exist if the universe underwent a rapid inflationary phase after a true Big Bang singularity. ...

His famed South Pole “discovery” of primordial gravitational waves was actually galactic dust—and that failure was career‑defining.
The BICEP experiment at the South Pole briefly appeared to detect the “baby picture” of the universe: microwave patterns interpreted as gravitational waves from inflation. ...

Keating sees science and God as intertwined questions, but insists both believers and atheists must accept unresolvable ambiguity.
As a “devout agnostic” and practicing Jew, Keating argues that science is about evidence (he doesn’t ‘believe’ in gravity; he measures it) while God is fundamentally beyond empirical proof or disproof. ...

The chain of cosmic coincidences needed for humans to exist suggests intelligent life may be extraordinarily rare.
To get us, Keating says, the Earth needed: (1) a colossal planetary collision to form the Moon (stabilizing tides and climate), (2) comet bombardment to deliver just the right amount of water, and (3) a dinosaur‑killing asteroid at exactly the right time to clear evolutionary space for mammals. ...

Religious practice can be behaviorally valuable even if you’re unsure what you believe.
Keating challenges Steven’s agnosticism by asking: if you truly think God might exist, how does that show up in your behavior? ...

Meaning in life comes from irreplaceable connections and consequential commitments, not prizes or status.
Earlier in his career, Keating’s meaning was dominated by the quest for a Nobel Prize, partly to outdo his scientist father. ...

Many popular ideas—simulation theory, aliens, astrology—are possible, but currently unsupported by hard evidence.
On simulation theory, Keating explains how future computing could in principle simulate entire worlds, but notes there’s currently no empirical sign we’re in one; some astrophysical tests even argue against certain simulation models. ...

Questions Answered in This Episode
If the Simons Observatory ultimately finds *no* evidence of inflation or a singular beginning, what specific alternative cosmological models do you think will gain the most traction, and how would that reshape your own theology?

When you realized BICEP’s ‘discovery’ was actually dust, what concrete safeguards or methodological changes did you implement in your subsequent experiments to prevent a similar confirmation bias from creeping in again?

You argue that religious practice is behaviorally valuable even if God doesn’t exist; what aspects of Jewish practice would you *stop* doing first if future evidence convinced you that a creator is definitively impossible?
Keating and Steven Bartlett explore the tension between science and religion, agnosticism versus practice, and why Keating remains a devout, practicing Jew while insisting God can’t be proven or disproven by physics.

Your argument that our existence required an incredibly specific sequence of cosmic accidents suggests extreme rarity—how do you respond to critics who say this is just an anthropic selection effect rather than evidence we’re likely alone?
The conversation widens into the rarity of intelligent life, simulation theory, astrology, free will, and what gives life meaning, with Keating arguing that our likely cosmic loneliness heightens our responsibility to each other and to the fragile planet that made us possible.

You’re skeptical of astrology because its mechanisms contradict known physics; by the same standard, what would a minimally plausible ‘mechanism’ for answered prayer or divine interaction with the physical world have to look like to be scientifically discussable, even if not yet observed?

This is the shrapnel of an exploded star, and this is a meteorite scoop from over four billion years ago. And this is what Elon will kill for.
Wow.
And all of this is to understand that fundamental question, people wanna know, how did we get here?
And how does the question of God tie into all of this?
Well, for the first time in history, we might be able to answer that question with scientific hard data.
Brian Keating is an astrophysicist and professor whose groundbreaking research and digestible explanations uncover everything we want to know about the universe and what lies beyond.
We go way back. 400 years ago, a genius named Galileo looked through a telescope, and he realized that we are not the center of the universe. And now we know the universe is vaster than you or I can comprehend.
How big would Earth be on this table?
Small.
Not even a grain of sand?
Even our galaxy wouldn't be a grain of sand. But we still don't know how the universe began. And so one experiment took me to the South Pole, to the bottom of the planet, and we thought we'd discovered the creation of time and space itself. Took me to the brink of a Nobel Prize, and we were on the front page of every newspaper. But it turned out we didn't see that at all. What we saw was... and we were crushed. I don't get too emotional but... We had to retract these discoveries and it was the most crushing experience a scientist can have. But you cannot stop doing experiments to answer these questions.
Now you've launched this $200 million project.
Yeah, and the data that this experiment is seeing is exquisite because now we know 100% that-
This has always blown my mind a little bit, 53% of you that listen to this show regularly haven't yet subscribed to the show. So could I ask you for a favor before we start? If you like the show and you like what we do here and you wanna support us, the free, simple way that you can do just that is by hitting the subscribe button. And my commitment to you is if you do that, then I'll do everything in my power, me and my team, to make sure that this show is better for you every single week. We'll listen to your feedback, we'll find the guests that you want me to speak to, and we'll continue to do what we do. Thank you so much. Dr. Brian Keating. What is the mission that you're on?
I think I'm the luckiest man on Earth. I get to get paid, not that much, but I get to get paid to study the questions that I was most interested in as a 12-year-old pimple-faced kid in Upstate New York, which is, how did we get here? And I think it's the question that people just wanna know. It's the only question you can't know, right? What happened before you were born? You, you have to rely on other people's word for it, right? You have to ask questions and be curious. And what is the only event that ever happened for which there was nobody around to ask? And that's the origin of our universe. And the universe contains everything. Contains life, minds, consciousness. Everything down to, you know, podcasters and, and, uh, and daily life.
