It would be great if we could meet at a nearby university and check whether in fact the spectrum does reverse when we view a hot object through any gases of your choosing.
When and where can we meet??
The CERN experiment shows that the wavelength of a H+ matter and H- antimatter are exactly the same but does not mention whether the spectrum was a black absorption line or blue/green emission line so we still need to get this confirmation from them.
Within experimental limits, the result shows no difference compared to the equivalent spectral line in hydrogen. This is consistent with the Standard Model of particle physics, the theory that best describes particles and the forces at work between them, which predicts that hydrogen and antihydrogen should have identical spectroscopic characteristics.
We find that the shape of the spectral line agrees very well with that expected for hydrogen and that the resonance frequency agrees with that in hydrogen to about 5 kilohertz out of 2.5×1015 hertz.
What we want is to see the visual spectroscope image. We do not dispute the frequency vibration and energy are the same for both the matter and antimatter variants, it is just whether is it an absorption or emission spectrum that needs clarification.
If you understood how anti-atoms were structured, you would understand why the absorption spectra are identical. It takes the same amount of energy to excite the positron in antihydrogen as it does to excite the electron in hydrogen because both are bound to their respective nuclei by the same amount of force.

If its absorption then stars are made of antimatter, period.

One reason the sun cannot be made of matter and anti-matter, is the sun does not burn itself out in short time. A Matter and Antimatter sun would have the proper fuel to oxidizer ratio, (to use the term oxidizer loosely) for a runaway chain reaction. The sun would burn itself in a very short time, with blazing glory, Instead, it burns slow and steady, suggestive of a controlled burn. This would require a way to segregate the matter and anti-matter. The observed controlled burn of the sun, also suggest that existing theory may have a problem, A large fusion core in a middle of a hydrogen based sun, also has a good fuel setup for a gobal chain reaction.. Why does the sun, using existing theory, not chain react into a blaze of glory? How does the sun's fusion core limit the input of hydrogen fuel or how does it limit the expansion of fusion outward, so the sun can last for billions of years?
Exactly so, the suns output is limited/stabilized by the planetary matter returning electrons that magnetically helix around the incoming H+ ions in the solar wind. Planets can't just absorb positive charge without completing the electric circuit. Its like electricity you need two wires to get a flow of current round and balance the system. When the return electron hits the sun it cancels a positron which releases a negative neutrons worth of light energy to the planetary object and we stay warm.

No need for anything complicated; the reaction is fairly slow, mainly because the nuclei that have to react are positively charged and strongly repel eachother.
Wouldn't solar flares and sun spots, which reflect vastly different amounts of energy reaching the surface, suggest there is a variability in the amount of the fusion?
Charges will indeed repel. However, a charge in motion will create a magnetic field. Similar charges moving in opposite directions will attract each other through their magnetic fields. So again, what prevents fusion from running away, seeing fusion is highly exothermic?
As positive charge is evacuated from the core due to the "nuke burn",
negative neutrons
Yes, you consider the neutrons to be electrically neutral
but neutral to what?
The touchable outside enclosure shells of course.
but if the sun corona is antimatter

Quote from: puppypowerHow does the sun's fusion core limit the input of hydrogen fuel or how does it limit the expansion of fusion outward, so the sun can last for billions of years?The rate-limiting step in a star the size of the Sun is:proton + proton -> deuterium (=bound proton+neutron) + neutrino + positronThe protons are both positively charged, and when they collide, they just repel each other, and fly away again (no reaction).- Helium-2 is extremely unstable!However, if, at the very instant that two protons collide, one of the protons decays into a neutron (+shrapnel), then you can form Hydrogen-2 = Deuterium, which is stable- This coincidence is extremely unlikely, as the decay of a proton into a neutron is mediated by the weak nuclear force, which operates on long timescales compared to the strong nuclear force.- Deuterium, once formed, fuses very easily to form the familiar Helium-4 nucleus, which is extremely stable (and releases lots of energy)- In fact, Deuterium fuses so easily, that even brown dwarfs, about a dozen times bigger than Jupiter are able to fuse Deuterium, even though they can't fuse ordinary Hydrogen (they don't have enough temperature and pressure).See: https://en.wikipedia.org/wiki/Stellar_nucleosynthesis#Hydrogen_fusionThe other rate-limiting step is temperature and pressure. If you double the mass of a star, the temperature and pressure in the core increases, and the rate of fusion increases by a factor of around 16.- That's why red dwarf stars (with a mass perhaps half the Sun) will outlast the Sun by billions of years.
