What is the point of approximate Large Scale Structure simulation with neural networks?

People use N-body simulations to compute Large Scale Structure (LSS). To use this method you need to make assumptions about the underlying physics, e.g. the parameters of the Universe expansion, the ...

When should we use direct O(N^2) N-body simulation (instead of other methods)?

I've read a small tutorial on N-body simulation methods. What it says about direct N-body simulation is: These codes are often used in star cluster dynamics or in other contexts where multiple stars ...

Large scale structure/Single galaxy simulation on GPU

I noticed that most of the tools for cosmological simulation (e.g. large scale structure or single galaxy evolution) are based on GADGET. It only allows to use CPU. Why not GPU? What is the main ...

How well are planetary formation models (e.g., determining $\mathrm{\dot{M}_{planet}}$) understood in 2024?

I know that planets can form through accretion, bulging up from $0$ to their final mass $\mathrm{M_{planet}}$ at $\mathrm{M}(t_f)$. I know that when studying Planetary formation and migration theories,...
