I asked for evidence. You have yet to supply any. Until then, we have no reason to believe that the gravitational constant is wrong.

I think it is sensible to wait for the results of the experiment.
You can if W≠mg.
Quote from: Yaniv on 27/01/2023 03:49:31You can if W≠mg.But it is- by definition.

You seem reluctant to conclude the experiment. Why?
Quote from: Yaniv on 28/01/2023 05:36:07You seem reluctant to conclude the experiment. Why?I can't conclude something I never started. There are also two other problems:(1) I don't have the equipment needed to do such an experiment.(2) Even if I did have such equipment, you haven't told me the needed precision that I would need to measure to. We already know what a positive result would look like (any decrease in weight with temperature would be a positive result). But what about a negative result? If someone measured the weight and found that it didn't change with temperature, would you accept that result or would you say, "your experiment wasn't precise enough"? That's why you have to define the measurement limits. Otherwise, you can keep saying, "your experiment wasn't precise enough" after an endless number of increasingly precise tests that found no weight change.
20 grams metals heated by 5 degrees C in air lost 100 micrograms (Glaser,1990). Let's start there.

Let's start there.In order to best measure the effect, you'd want to maximize the difference in temperature between your measurements. That being said, what kind of relationship are you expecting? Does doubling the temperature double the weight loss?

Does doubling the temperature double the weight loss?I expect a linear relationship between heat absorbed and weight loss. Doubling the calories absorbed should double the weight loss.

The mechanism for W reduction at increasing T in vacuum is described in my theory on my website here yaniv-stern.webnode.page.Glaser paper is below.https://www.semanticscholar.org/paper/Response-of-apparent-mass-to-thermal-gradients-Gl%C3%A4ser/dd77e00123f2e0efe31f02f9b0b717a98620172c
Glaser paper is below.https://www.semanticscholar.org/paper/Response-of-apparent-mass-to-thermal-gradients-Gl%C3%A4ser/dd77e00123f2e0efe31f02f9b0b717a98620172cI looked at your reference. The author states: 'it is predominantly free convection forces which change the apparent mass.'
