I'm not a programmer, so I am unable to write such kind of addon, but what do you think about particle physics in Celestia?

OK, I know, it seems to be a serious mistake, because we are talking about something very small in a program to visualize something very big... But there are events, where you can see particle physics in a really big scale. They are very common in Earth's atmosphere. I'm talking about cosmic gamma rays hitting our planet. Yes, particles are small, but cosmic ray showers are really huge - and really beautiful to watch.

Run this simulation (it's safe) - it looks really, really impressive. Don't you think that similar simulation in Celestia would be an amazing thing to watch? There was a beautiful addon with magnetic lines, so...

Oh, OK.... I have missed that topic:

Sorry, I see you have discussed this problem

Being a particle physicist myself, I agree that there are many particle physics aspects that we might potentially integrate into Celestia. The most striking effects would be apparent in visualizations of the early universe. That sort of stuff is potentially exciting but needs careful planning first...

I already asked for this, few days ago, in another thread. Particle physics IS linked to cosmology and the reverse is also true. The only addon about this kind of stuff (AFAIK) is my own addon about Earth's magnetic field and trapped charges particles (check out the "Magnetic-Earth" addon, now available on the Motherlode).

Cosmic rays showers are a very important thing for astronomy, and it's a "shame" Celestia can't show them.

We call this wedding "Particle Cosmology" and "Astro-particle physics"

Of particular interest are neutrinos in the context of UltraHigh Energy cosmic ray events. The final challenge would be to discover the analog of the Cosmic Microwave backround (CMB) with neutrinos! This would probe the early Universe, much earlier than the CMB radiation does! The greatest type of events would happen when such relic neutrinos would collide with cosmic neutrinos (from some hitherto unknown sources) via an intermediate Z-boson resonance (so-called Z-burst scenario). The Z-boson resonance would give a tremendous, observable enhancement and possible absoption dips in the neutrino energy spectrum around 10^21 (!) Evolt, depending on the neutrino mass!! So apart from a possible discovery of the cosmic neutrino background even a cosmic ray determination or at least a competitive limit of the neutrino mass is thinkable. The laboratory where our main hope is resting on is of course the Auger lab in the Pampas of Argentina!
Moreover, the neutrino telescopes AMANDA and ICECUBE at the South pole, where my lab is strongly involved carry great hopes.
