- BugsJustFindMe 1y ago> It’s pure hydrogen The gas around it is pure hydrogen. We can't know what's inside. Could be stacks of little green men and ponies in there.
- ndsipa_pomu 1y agoArguably, it makes no difference at all as to what's inside (apart from the inference that the early universe had lots of singularity seeking ponies and little green men)
- catchclose 1y agoMaybe, lazy or tired light, and everything shifts towards specific spectral lines or frequencies/wavelengths at distant observation. Attenuates? Asymptotes to the hydrogen line?
- adgjlsfhk1 1y agothat doesn't work out. from the spectra we're seeing hydrogen spikes red shifted, so the lack of any other spikes is very strong evidence
- catchclose 1y ago!
- jfengel 1y agoIf light got tired it would make ordinary chemistry impossible. You wouldn't see spectra because atoms themselves would work differently (and probably not at all). The fact that we can tell that it's hydrogen makes it extremely unlikely that light behaved differently there.
- PantaloonFlames 1y agoThanks , very helpful.

- sandworm101 1y agoWell, the black hole isnt hydrogen. This is the gas around it. And being pure hydrogen seems sus as there should be some helium in there according to most models. https://en.wikipedia.org/wiki/Big_Bang_nucleosynthesis https://en.wikipedia.org/wiki/Big_Bang_nucleosynthesis Not only that, but getting stars to form using pure hydrogen is tricky. That helium helped early stars collapse and ignite. Not seeing any helium in an early-universe object is a big deal, suggesting some sort of error.
- felbane 1y agoBug fixes: - Corrected an infrequent issue with getResultingProtonCount that would cause it to always return 1 for certain origin bodies. (In the merge request comments: "This why we don't let junior devs commit unreviewed code to critical branches, guys.")
- Cthulhu_ 1y agoWas it wrong, or based on incomplete data?
- perching_aix 1y agoBoth at the same time? Weird question.
- HPsquared 1y agoIn most fields it's impossible to have complete data.

- tempodox 1y agoIf you draw conclusions from incomplete data, they tend to be wrong. Even Prof. van Dusen and Sherlock Holmes knew that. So if there were any difference, it would be sheer luck.
