No One Is Going to Mars: A Physicist Debunks Elon Musk's Mars Fantasy w/ Adam Becker
July 15, 2026
AI Summary
5 min readOne of the most jarring details in Adam Becker’s new book is that the dirt on Mars is toxic. Not just inconvenient or abrasive, but laced with perchlorates, a class of chemicals that disrupt the thyroid and are poisonous at high concentrations. The dust is fine enough to stick to spacesuits, get tracked into habitats, and seep into water and food. For Becker, a physicist and journalist, that single fact broke whatever complacency he had left about Elon Musk’s vision of a million-person Martian colony. The conversation that follows is a methodical dismantling of that vision, grounded in physics, biology, and the real economics of spaceflight. The argument is not that space exploration is worthless; it is that the settlement fantasy sold by Musk, Jeff Bezos, and their peers is pseudoscience deployed to consolidate power and wealth on Earth.
The Mars Colony Is a Physics Problem, Not an Engineering One

What you'll learn
- 1 (01:43) **The Core Thesis: There Is No Planet B** - Becker states the foundational argument: Earth is the only viable planet for humans, and tech billionaires' space fantasies are built on pseudoscience and delusion.
- 2 (03:13) **Origins of the Obsession: Childhood Sci-Fi and Colonial Fantasies** - Becker traces the roots of Musk and Bezos's space dreams to science fiction they read as kids, which they misinterpreted as a roadmap for the future.
- 3 (06:31) **The Real Launchpad: Government Contracts, Not Private Innovation** - Both SpaceX and Blue Origin were kickstarted and are still largely funded by taxpayer money through NASA contracts.
- 4 (10:34) **Mars as a Marketing Lightning Rod** - Mars became the public goal in the 2010s, with Musk acting as a charismatic, messianic figure promising a near-future Martian colony.
- 5 (16:25) **The First Barrier: Just Getting There** - The physical journey to Mars presents immense, often overlooked challenges that are far harder than going to the moon.
- 6 (19:28) **The Insurmountable Problems of a Colony** - Even if you arrive, establishing a permanent settlement is nearly impossible due to a cascade of hostile conditions.
- 7 (22:46) **The Scale Problem: You Need a Civilization, Not a Colony** - Musk's goal of a million people on Mars is far too few to create a self-sufficient, high-tech economy.

We are never going to Mars. And the billionaires selling you the dream are lying to your face.

The idea of living on Mars has become one of Silicon Valley's biggest promises. Elon Musk, Jeff Bezos, and other tech billionaires claim humanity's future depends on becoming a multi-planetary species. But what if nearly everything you've been told about colonizing Mars is quite literally scientifically impossible?
In this week's episode of Power User, I sat down with physicist and science journalist Adam Becker, author of More Everything Forever, a fantastic book that I absolutely loved, to break down the biggest myths about Mars colonization, SpaceX, AI, and Silicon Valley's vision of the future.
We discuss why Mars is far more hostile than most people realize, the scientific barriers that make permanent settlement nearly impossible, and why billionaires continue selling this vision despite knowing it will never become reality.
We cover:
Why humans will literally NEVER live on Mars
The biggest scientific problems SpaceX can't solve
The truth about Elon Musk's Mars colony plans
Why Silicon Valley keeps selling science fiction as reality
How AI and space colonization became part of the same billionaire narrative
Why investing in Earth may matter far more than escaping it
