How exactly does energy become mass?

[Dmitry67]

No, of course.
Mass of He4 is smaller then 2 neutron + 2 proton masses.

You could say that energy becomes mass when the wave collapses into particle form. As for pure energy, one might say that the closest thing to this might be the primordial first field that came into being after the big bang.

Energy becomes mass in: foton + molecule = triggered molecule?
and primordial first field: backgroundradiation?

It is a pity that of changes of energy levels of one electron we don't even know how this takes place which would be part of the answer to the posed question. I do believe that the formula's are there to calculate the amount of energy change.

I think that counts also for infrared emission. Process unknown yet calculation of amount: on one side of the equation Max Planck:
hf = 2 pi f hbar = omega hbar
(sorry have to learn more about the symbol-editor)
and on the other side delta m c^2.
The delta m coming out of the mass-velocity relation.
If it is right to use any inertial system, why not use the inertial system comoving with the backgroundradiation?

>>their combined mass is greater than their separate mass.
Does not make sense to me

Does it have to? These aren't billiard balls here. Don't look to the classical world.

 

[Gerinski]

Approaching the question from a different angle from what has been discussed until now, wouldn't it be another type of answer to say that "energy is supposed to become mass via the Higgs mechanism"?

 

[JANm]

No, of course.
Mass of He4 is smaller then 2 neutron + 2 proton masses.

Hello Dmitry67
Isn't it more official to compare 4 hydrogen and He4 and the mass loss during that proces? Or should you not at least compare one He4 with 2 neutron + 2 proton + 2 electron masses?
