Curving charged particles in magnetic fields is a completely different experiment to weighing a heated metal in vacuum. Don't you think E=mc2 should be tested by different types of experiments ?

Different kinds of experiments have already been done to verify it and are being done every day. Positron emission tomography measures that gamma ray energies equal to that predicted by E=mc2 are released when electrons and positrons annihilate each other. Even as far back as 1932, the Cockcroft-Walton generator verified E=mc2 to an accuracy of 0.5% by transmuting lithium into helium and measuring the mass and kinetic energy of the resulting particles. E=mc2 is tested every time a nuclear reactor is powered up. We have more than enough information to know that E=mc2 is highly accurate.

We don't have data on the temperature measurement of a thermometer in the Sun. All we have are predictions.

It has been.
https://www.nature.com/articles/4381096a
https://en.wikipedia.org/wiki/Nuclear_binding_energy
etc.

The equation is a consequence of relativity.
Relativity has been tested  many times to high precision
https://en.wikipedia.org/wiki/Tests_of_special_relativity
https://en.wikipedia.org/wiki/Tests_of_general_relativity

So, there's no sensible argument that the equation is wrong.

Now let's test it.
How?
The prediction is that the change in mass will be far too small to measure for any practical temperature range.
Of course, there's still nothing stopping you doing the experiment.

Now an experiment is required to test if your prediction matches the results.

It has to be. We know from E=mc2 that energy has an associated mass. Where there is extra energy, there is extra mass to go with it. Heat is a form of energy. So an object must weigh more when it is hot than when it is cold. This is rather like you saying, "We don't know if Ek = 1/2mv2 (the kinetic energy equation) is highly accurate at predicting the effect of dropping an elephant on Mars from 10 meters up.". Just because no one has done that experiment before doesn't mean we don't know how to calculate what its kinetic energy would be if one was to be dropped on Mars from 10 meters up.

Quote

No, because it isn't a necessary experiment to establish that the Sun is hot. We have mountains of other data already. Just as it isn't necessary to weigh heated metal in a vacuum to establish that extra energy adds extra mass to an object.

The Sun's temperature hasn't been measured with a thermometer either. Are you going to say that we can't really be sure that the Sun is hot until we do that?

It isn't necessary to do so when we already have enough information about the laws of physics to tell us what will happen.

Quote
I find your analogies stupid.

They're perfectly apt analogies. You claim that, despite mountains of evidence that E=mc2 is correct, we can't use it to make accurate predictions about the effect that thermal energy has on mass. It's exactly the same as claiming that, despite mountains of evidence that the Sun is hot, we can't use it to make accurate predictions about the effect it would have on a thermometer. The exact same kind of reasoning underlies both.

You claimed that an experiment which determined that E=mc2 is accurate to 1 part in 1 million (in addition to many other previous confirmatory experiments) is "faith, not fact". If you can call some kinds of high-precision, hard data "faith, not fact", then there's nothing keeping you from doing the same to other forms of high-precision, hard data. Like the Sun's temperature, for example. Or do you just have some kind of special double standard that you only apply to E=mc2 that you let other scientific principles get a free pass on?

You are welcome to make predictions about the effect of T on W. Next is to test your predictions against results.

No. I claim your statement W does Not change at increasing T is faith because we don't have the results of the experiment.

I think had it been possible to place a thermometer in the sun it would have been a great experiment to test if it's readings agree with theoretical predictions.

Because it's a really stupid proposal.
We know that the change in mass is too small to measure directly.

It wouldn't help.
We know that the mass change would be too small to measure.
And it would still be too small to measure if it was a thousand times bigger.
So doing the experiment wouldn't even tell us if we were wrong by a factor of a thousand.
So it's pointless.

We don't know if the change in W is too small to measure because we haven't completed the experiment.

I think his analogies are an attempt to confuse, deflect and discourage scientists from concluding the most important experiment in history of physics.

Had I done the experiment myself you would have discarded the results as quickly as you discarded the results of the references provided. I want this experiment concluded by the best experimentalists on the planet.

Only in as much as we are unsure of them. Or to increase the precision of our measurements. Existing experiments are good enough to do both of those things.

Quote

Like testing the prediction that a thermometer in the Sun would read it as hot?

Quote
No. I claim your statement W does Not change at increasing T is faith because we don't have the results of the experiment.

We know from the before-mentioned experiments that energy has mass. Therefore, by saying that mass increasing with temperature is "faith, not fact", you most certainly are saying that the high-precision experiments used to determine the accuracy of E=mc2 are "faith, not fact".

Quote
I think had it been possible to place a thermometer in the sun it would have been a great experiment to test if it's readings agree with theoretical predictions.

So you don't believe we can say with confidence from existing data that the Sun is hot? We would have to put a thermometer in the Sun in order to be sure of it?

Your claim W increasing with T is "faith" based on your confidence in your theory. We don't have the "facts".
I suspect all physical equations based on F=ma are false and over the years developed and corrected by addition of new functions to match results and E=mc2 is a reduced expression of many equations.
W reduction at increasing T in vacuum disproves E=mc2 and provides support for my view on the evolution of physics.

It's confidence in data.

We don't have the "facts".

If you don't think experimental data is factual (or at least as close to fact as one can philosophically reach), then there's no point in doing experiments of any kind because obviously experiments don't tell us anything useful.

How can you disprove something that's already been proven? Do you think that physicists are part of some massive conspiracy that invented the experimental results out of thin air when they said that they had measured E=mc2 to be accurate to 1 part in 1 million? That's the only option you have. In order for your model to be correct, those physicists must have been lying (or at least exceedingly stupid).

I don't think they invented the results in this case. I think physicists invent corrections to false mathematical equations and this can be tested by concluding the proposed experiment.
