Welcome back to Impact Theory with Tom Bilyeu. In today’s episode, Tom Bilyeu dives deep into one of the most provocative questions facing science and philosophy: Do we really have free will, or are we all just highly sophisticated NPCs—non-player characters—running a program inside a vast, resource-efficient simulation? Drawing on groundbreaking neuroscience experiments, the story of Phineas Gage, quantum mechanics, and the work of leading thinkers like Robert Sapolsky, Tom Bilyeu challenges everything we think we know about choice, consciousness, and the true nature of reality.

But this isn’t an episode about nihilism. Instead, Tom Bilyeu reveals why embracing the truth of a stochastically deterministic universe can actually make life feel more meaningful, freeing us from the weight of the past and inspiring us to make the most of every moment—programmed or not. Get ready to question your assumptions and see the world from a whole new perspective.

🚀 The Alien Civilizations That Chose Infinite Knowledge Instead of Space Travel

What if advanced alien civilizations achieved infinite knowledge not through space travel, but by harnessing the power of stars? This video explores how a type 2 civilization could repurpose a star into a giant computer, a concept tied to the kardashev scale and the theoretical dyson sphere. It’s a fascinating look into advanced future technology and the potential of artificial intelligence in the cosmos.

Where Are All The Alien Robots? The Chilling Idea Of Von Neumann Probes

As you know, I’m obsessed about the Fermi Paradox. Where are all the aliens? But an even stranger question is: where are all the robot aliens?

If you’ve seen at least one other episode of the Guide to Space, you know I’m obsessed about the Fermi Paradox. This idea that the Universe is big and old, and should be teeming with life. And yet, we have no evidence that it exists out there.

We wonder, where are all the aliens?

Insectoid Aliens — Hive Minds, Swarms, and Alien Evolution

Forget little green men — the galaxy’s most likely aliens may be hives and swarms. From biology to starships, insectoid life could shape civilizations stranger than ours.

Astrophysicists use ‘space archaeology’ to trace the history of a spiral galaxy

Billions of years ago, a young spiral galaxy began to grow in a crowded part of the universe. It pulled in gas and small companion galaxies, slowly building up the bright central region and sweeping spiral arms we see today.

In a new study published in March 2026, my colleagues and I used this galaxy’s chemical fingerprints to reconstruct its life story in detail.

Astronomers want to know how spiral galaxies like our own Milky Way came to be, as these galaxies can give us hints about how the elements we rely on, such as oxygen, were created and spread through space over time.
