Nullframe
Weight is a negotiation.
Null cavities suppress vacuum modes along a chosen axis. Gravitational mass remains. Inertial mass does not.

01 · The problem
Gravity isn't the enemy. Inertia is.
Every rocket fights its own mass. Every tower carries itself before it carries anything else. Equivalence made that feel inevitable: inertial mass and gravitational mass, locked together.
We treat inertia as a coupling, not a substance. Matter resists acceleration because it is entangled with the quantum vacuum. Change the vacuum modes available along one axis, and the coupling softens. The object still weighs what Earth demands. It no longer resists motion the way Newton assumed.
Rockets burn propellant to push against inertia. Structures thicken to survive their own weight. Both are negotiations with a coupling that was never fundamental. Only convenient.
02 · Technology
Null cavities.
Nested Casimir metamaterial stacks, cryogenically locked. Geometry that forbids vacuum modes along a single chosen axis.

Vacuum-mode suppression
Between parallel conducting boundaries, certain electromagnetic zero-point modes cannot exist. We stack anisotropic metamaterial plates into a cryogenic cavity whose forbidden band is aligned with a laboratory axis. That axis is the null axis.
Machian inertia
In the Haisch-Rueda-Sakharov picture, inertial mass is a reaction force from vacuum fluctuations under acceleration. Thin the mode density along one direction and the reaction softens. Equivalence fails along that axis alone. The failure is measurable.
The claim
Gravitational mass remains. Earth still pulls. Along the null axis, inertial mass drops. Objects do not float. They fall sideways through their own inertia. We call it inertial decoupling. Engineers call it an equivalence violation.
m𝑔(ẑ) ≈ m𝑔₀ | mᵢ(ẑ) ≪ mᵢ₀
03 · Products
Four product lines.
NF-D
Drive
Δv without the propellant bill.
Spacecraft systems that are not thrusters. Point the null axis, apply a tiny conventional force, get large Δv. Ships look wrong: no big engines, just a cold ring and a lot of nothing. Hard problem: cavity coherence under rotation. In progress.
NF-B
Buoy
Structural lightness.
Architectural mass-offset. A tower's effective weight is bled into a lateral inertial channel and dumped into bedrock anchors. Skyscrapers that should not stand. Bridges with almost no piers. The load path is rerouted through spacetime's preference for vacuum modes.
NF-F
Feather Rooms
Soft microgravity. No parabola.
Hospital and fab cleanrooms where effective weight dials from 1g to 0.01g along the vertical. Surgeons operate on organs that barely sag. Chip fabs grow crystals without sedimentation bias. Soft microgravity without parabolic flights.
NF-A · Restricted
Anchor
The inverse.
Amplify inertial coupling. Make something heavier than it should be. Seismic dampers. Kinetic barriers. Briefed under separate clearance.
04 · Applications
Sectors in active briefing.
01
Aerospace
Propellant mass collapses. Mission Δv becomes a geometry problem, not a tank problem.
02
Architecture
Load paths that ignore their own weight. Spans that look impossible until you stand under them.
03
Medicine
Surgical fields at fractional g. Organs that hold shape without retractors fighting gravity.
04
Semiconductor
Crystal growth without sedimentation bias. Defect densities that used to require orbit.
05 · Proof
The paper was rejected.
The demo was not.
A dark-matter detector in a Norwegian mine kept throwing “negative mass” events. They were not particles. They were microseconds where a superconducting shield geometry accidentally suppressed vacuum modes along the vertical. A test mass briefly weighed less than its inertial response predicted.
One postdoc quit, filed the patents, and founded Nullframe. Peer review called the claim impossible. The cavity did not care. In a rented cryogenic bay outside Trondheim, a 2.4 kg niobium slug accelerated under a force that should have moved 180 grams.
We still keep the rejection letter. Framed. Next to the first cavity that hummed at a frequency you feel in your teeth.
06 · Company
Cryogenics. Metrology. Patents.
Nullframe builds and qualifies null cavities. Our labs run cold. Matte niobium. Pale instrument blue. Rooms that hum. We hire people who say “equivalence violation” the way others say “bug.”
Headquarters and primary cryogenic facility: Oslo region. Secondary metrology partnership: CERN-adjacent instrumentation network. Early backing from Imaginary Ventures.
