An exploration of the question of whether transhumanism, and the analogue in alien civilizations is in fact the great filter.

🚀 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.
Scientists Just Found New Evidence of Life on Enceladus
The question Enceladus is asking is whether the transition from chemistry to biology is easy or hard. Whether it is something that happens whenever conditions permit, or whether we are alone in a universe that almost got there but never quite did.
A small, bright moon, five hundred kilometres wide, has become the most precise instrument humanity has ever had for answering that question. And it is answering it in real time, one grain of ice at a time.
