Resolution criteria
This market will resolve to "Yes" if, before January 1, 2030, at 11:59 PM UTC, a government agency, a reputable scientific institution, or a recognized peer-reviewed journal confirms the existence, public demonstration, or successful operation of technology that directly counteracts gravity (anti-gravity).
For the purpose of this market, "anti-gravitational technology" is defined as a man-made device or system that achieves lift or propulsion through the direct manipulation or neutralization of gravitational fields, rather than through conventional aerodynamic lift, thrust, or electromagnetic propulsion (e.g., ion drives).
If no such disclosure or confirmation occurs by the specified date, the market will resolve to "No." In the event of ambiguity regarding whether a discovery qualifies as "anti-gravity," the consensus among major scientific news outlets (such as Nature, Science, or major credible news organizations) will serve as the deciding factor.
Background
The concept of anti-gravity—a hypothetical force that could nullify or repel gravity—remains firmly within the realm of theoretical physics and science fiction. General Relativity, the prevailing theory of gravity, describes it as a curvature of spacetime caused by mass and energy, rather than a force that can be easily "shielded" or "inverted."
While various researchers and fringe groups have periodically claimed to have observed anomalous gravitational effects (such as those associated with the Podkletnov effect or various "electrogravitics" claims), none have been replicated, verified by the broader scientific community, or transitioned into functional technology. This market tracks whether any legitimate breakthrough, discovery, or formal disclosure regarding such capability emerges within the next five years.
