You're right Dave, tails of comets are being carried outward by solar wind.

Isn't it experimentally confirmed that the mass of a particle increases when its kinetic energy increases by measurements for electrons which were accelerated by large differences in potential??
Interpreting the last info of mass increase, i would interprete the following...
By the fact that mass and energy are the same, i think with nuclear reactions it might be not right to say that mass is being converted into energy, or even that matter is being distroyed. it might be better to say:
restmass is a particular concentrated form of energy; you could call it 'bottled' energy.
i give you an example of a reaction...
1 ---7 --------4
H + Li gives 2 He
1 ---3 --------2
With this reaction some of this 'bottled' energy is liberated in the form of kinetic energy of small particles. This is being delivered to the environs, which becomes warmer owing to this. As the molecules of the environs acquire kinetic energy, so they acquire mass. So with a nuclear explosion concentrated rest-mass(-energy) is being converted into
the thermal mass(-energy) of the environs. There hasn't took place a total change-over in mass and nor a total change-over in energy; mass-energy remains the same.
E = mc² has been tested quantitatively.
When one uses mass-spectrography for the example i gave, then you find with 2He there is a loss of restmass.
When one calculates the mass of atoms out of the observed energys of nuclear processes, then you get very accurate atomic weights. When you compare the atomic weights you calculated this way with the weights you acquired by using mass-spectrography, then the correspondence is in such a way, that one hardly could desire a better proof for the equivalence of matter and energy.
i believe you're right when you say, there can't be mass without energy and there can't be energy without mass.
