Experimental confirmation of the gravitation force negative temperature dependence

TL;DR

This study experimentally confirms that the gravitational force on piezoelectric ceramics decreases with increasing temperature, suggesting a negative temperature dependence of gravity.

Contribution

It provides experimental evidence of gravity's negative temperature dependence using heated piezoelectric ceramics, expanding understanding of gravitational interactions.

Findings

Weight of piezoelectric ceramics decreases with temperature.

Results align with previous measurements on non-magnetic metal bars.

Supports further research with diverse materials and temperature ranges.

Abstract

The experiment with weighing PZT-piezoelectric ceramics, heated up by a high-frequency signal for the temperature of 1.6 C is briefly described. The negative change of piezoelectric ceramics weight having relative value of is confidently registered. The sign and the order of the value of relative temperature change of piezoelectric ceramics weight correspond to the measurements of weight of non-magnetic metal bars which were conducted earlier. What is emphasized as expedient for development of physics of gravitation is conducting similar measurements with use of various materials as samples and in a wide range of temperatures.
