A power source that isn't gravity, exactly.
How Bob Lazar's reactor works, what it does to time and light, and why he no longer thinks the effect is gravity at all.
The reactor
The Sport Model’s power source, according to Lazar, is a basketball-sized hemisphere sitting on a 15-inch square base plate. X-rays of the reactor revealed an internal particle accelerator, like a small cyclotron, bombarding a target.
The target is Element 115. Lazar named it in 1989. At the time, Element 115 did not exist in any periodic table. Mainstream science synthesised it in 2003. The synthetic version had a half-life of milliseconds. Lazar says his S4 sample was a stable isotope, sitting on the predicted “island of stability” of super-heavy elements.
Around the reactor sit three wave-guide emitters that Lazar called gravity amplifiers. In one configuration, all three contribute to lift. In another, all three focus on a single distant point, producing travel by short pulsed jumps with a 10-millisecond recycle between each one.
The amplifiers are not physically connected to the reactor. Lazar described the system as held together by no visible wiring. Power and signal both arrive wirelessly.
What Barry showed him
Lazar’s lab partner at S4, Barry Castillo, demonstrated the reactor’s effects on three occasions.
First: an impenetrable force field. Lazar tried to put his hands on the sphere and couldn’t. The first two or three inches had some give, then nothing. The strange part: the force was not transferred back to the reactor itself. The reactor didn’t push back. It just stopped him.
Second: the candle experiment. Barry placed a lit candle at the focal point of the gravity amplifier. The flame stopped moving. Lazar said it should be impossible because he could still see photons leaving the flame. Barry insisted it was frozen in time. In 2026, Lazar revealed there was a third experiment that was cut from the documentary: a mechanical wristwatch at the focal point. It also simply stopped.
Third: a small black sphere. Barry rotated the emitter further. A dark point formed in space, about the size of a tennis ball, where light bent away. Lazar called it a tiny black hole that was not affecting anything else in the room.
“I’m increasingly convinced that there’s another force of nature. We call this antigravity because there’s nothing else to call it. But I think there’s another force that we haven’t discovered. And that’s what this machine is taking advantage of.”

Hal Puthoff’s framework
Hal Puthoff has spent his career building a physics framework that would, in principle, allow what Lazar describes. He calls it metric engineering. The short version: spacetime can be modelled as an optical medium with a variable refractive index. If you can engineer the index locally, you can warp the metric. If you can warp the metric, you don’t need to move the craft. You move the bubble of space around it.
He wrote this up for the DIA in 2010 as part of the AAWSAP program, in a Defense Intelligence Reference Document called “Advanced Space Propulsion Based on Vacuum (Spacetime Metric) Engineering.” The paper is declassified.
The theory is not proven. It is also not crank physics. It builds on Miguel Alcubierre’s 1994 warp-drive paper, which sits in peer-reviewed general relativity literature.
If Puthoff’s framework is right, the Sport Model would not experience inertia or air resistance. Which is exactly what Lazar’s described observations would require.
