If space is a real physical medium—capable of carrying stress and waves—why don’t we feel it?
Why can matter move freely, light propagate without loss, and motion reveal no preferred frame?
This series addresses the most intuitive objections to a mechanical vacuum using standard mechanics, not metaphysics. It explains why solidity does not imply drag, why acceleration is different from motion, how inertia arises naturally, and why the vacuum remains experientially invisible.
Speculation is explicitly labeled and never required.
The goal is understanding—not persuasion.
Could the Vacuum Have Structure Without Chemistry? SERIES VII — LIVING IN A SOLID VACUUM How Motion, Freedom, and Transparency Are Possible Speculative, Optional Reading Up to this point, nothing in the argument has required the vacuum to be made of anything. We have only required that it behave like a real medium: That alone […]

When the Medium Pushes Back: Regime Separation SERIES VII — LIVING IN A SOLID VACUUM How Motion, Freedom, and Transparency Are Possible So far, the mechanical vacuum has seemed almost too accommodating. This raises a fair question: If the medium is real, does it ever actually push back? The answer is yes—but only when certain

Why Inertia Exists at All SERIES VII — LIVING IN A SOLID VACUUM How Motion, Freedom, and Transparency Are Possible Up to this point, the picture has been reassuringly quiet. But there is one situation where the vacuum does respond: When motion changes. This response is so familiar that we rarely question it. We give

Why Motion Doesn’t Reveal a Preferred Frame SERIES VII — LIVING IN A SOLID VACUUM How Motion, Freedom, and Transparency Are Possible Once a physical medium is introduced, a familiar objection quickly follows: If space is a medium, shouldn’t there be a true state of rest? Shouldn’t motion through it be detectable? This concern is

Why You Don’t Feel the Medium (But Light Does) SERIES VII — LIVING IN A SOLID VACUUM How Motion, Freedom, and Transparency Are Possible If the vacuum is a real mechanical medium—stiff enough to carry light—then a sharper question follows naturally: Why don’t we feel it at all? After all, we do feel air when

If the Vacuum Is a Solid, Why Can We Move Through It? SERIES VII — LIVING IN A SOLID VACUUM How Motion, Freedom, and Transparency Are Possible One of the first objections to any physical vacuum model is immediate and intuitive: If space is a solid medium, shouldn’t moving through it feel like moving through
