Traditional physics predicts weight (W ) should NOT change at increasing temperature (T) in vacuum. My theory predicts W should decrease at increasing T in vacuum and can be found here yaniv-stern.webnode.com. W reduction at increasing T in vacuum disproves conservation of mass and most of the rest of physics. Over the past ten years I contacted thousands of scientists to weigh a heated metal in vacuum and publish the results. I didn’t get the results of the experiment. Results required.
