Been looking at Jupiter with all the reactors all over it wounding if its just a unborn star waiting to reach .....
I would be willing to bet that most of the doubt around the theory of metallic hydrogen in the gas giants (which I remember and I'm only 24) came from a fear that such a confirmation would vindicate Robitaille's criticisms of the gaseous sun model, as well as his literal advocacy of a liquid metallic hydrogen model of the sun since before gas giant metallic hydrogen became basically undeniable even by the mainstream astrophysics community. There is something of a tension in astronomy between planetary and stellar modelers; the standard stellar evolution model rather pointedly ignores the initial accumulation of gas and dust into a planetary sized object that even the Jeans swindle requires, preferring instead to treat the initiation of the hot core fusion their model requires to avoid the gravitational collapse becoming a singularity as literally the beginning of time, and ignoring all possible things that came before unless there's a spectral anomaly in the isotopes they see, which they then blame on "tainted/heterogeneous pre-stellar dust" basically.
There are a lot of anomalous spectra (for example, the sun has about one 140th of the Lithium it should according to LambdaCDM; there's also the star that has elements in its spectra we've literally never seen or produced, namely Flerovium 298 or the star that's only 200 light years from us for which they still don't have a consistent modification to their models to make it not look very much like it is ...older than the universe).
They have also never seen a Population III star, ever. They are also resolutely confident that Population III stars existed. The further back they look in our light bubble, the shorter the timespan that LambdaCDM has to get the Population III stars to form, fuse Big Bang nucleosynthesis hydrogen/helium, and then go supernova to make all the things that we see in the Population II stars so that enough supernovae have happened by the time Population I stars like the sun form that we can have planets with a nonzero percentage of elements heavier than iron (yes the population designation increases in the reverse order they formed, because scientists are weird). JWST is perfect for looking for Population III stars, which is one of the things I am most excited about it - I don't think they'll find any, and LambdaCDM kind of needs them to. I'm fully prepared to eat my words, but only if there is no ambiguity in the detection (i.e. the star has only hydrogen/helium spectral lines).
