What's really fascinating is that it starts out as more of an elliptical galaxy, and only gains its characteristic spiral arms from collisions with other smaller elliptical and irregular clusters.

Well it’s not really an elliptical, more like an irregular galaxy at first. However, one it gained mass the conservation of angular momentum combined with the gas rich area formed it into a spiral.

Can you do an Oort cloud sim please. If there are so many artist images of Oort cloud of a very similar geometry, then with a sim the same as a galaxy can give us the same geometry as the art images? from a pre-disk system and also as a cross-section views. The Oort cloud images must have used a physical equation base, so we can use them as a 3D gravity cloud visual?

"This TNG50 galaxy will be similar in mass and shape to Andromeda (M31)", but only ends up with a galaxy stellar mass of 47 million suns? I thot M31 was closer to 1000 billion suns in mass...Wikipedia shows Mass (1.5±0.5)×1012[9] M☉.

Sometimes periods are used in place with commas with numbers, i.e. you're meant to read it as 47,000 million suns rather than 47.000 million I'm guessing that's what's going on, but even then that'd put it below the Milky Way's mass let alone Andromeda's.

It directly tests our understanding of the laws of physics to see if it stands up to the scrutiny of a simulated environment with the same laws. It can show flaws in our understanding of the laws of physics to see where we need to study more and challenge our assumptions.

wtrange, we don't see the galaxy, only its border. Is there something to hide during the galaxy formation? Look at the trick at the beginning: there are mainly two opposite gaz sources. Not exactly opposite to let the planar and spiral galaxy formation.... These simulations are known to follow hydrodynamics rules in their software... so it's not surprising to observe a vortex because of these two gaz sources. So this is not a simulation, this is an animation, this cosmologic event only mimicks macroscopic phenomenons, that's all. We know that there are too much unknown parameters in the galaxies to achieve a real simulation. Don't say "look, i have reproduce the original necessary conditions to form flat spiral galaxies, look, it works!", no you just have built a scam

Wrong assumption on your part they are simulating gravo-magnetohydrodynamics . www.tng-project.org/ just so you know what is actually the scale and what the video shows, and if you want to know about the previous versions which is released for public on arxiv.org/abs/1812.05609
