Mach 3 Bubble Shockwaves 

Isn't it simulated? With a powerful computer it shouldn't take much long?

Wait no I think it's animated

Some simulations can be so accurate that experiments can't beat them

5th-order accurate in time and space is quite accurate. Likely less than 1% deviations from absolute (if you could reproduce exactly in lab, which cannot). The actual computation keep track of (mass or energy) residual, which can be 1e-6 (0.0001%) or lower (can be arbitrarily set, but depends on compute resources and time)

This looks like an Large Eddy Simulation (LES). At these high speeds (high Reynolds numbers) the Kolmogorov scale is going to be very small so not even supercomputers can resolve after thousands of years of computation. Subscale turbulence modeling (such as Smagorinsky methods) combined with LES (resolving 80% of turbulent kinetic energy) can yield very accurate resolution/properties above the Taylor length scale, though will deviate increasingly below that scale (in terms of truncation and dissipative error).

I have an ideea about how solar heliosphere works. Is like a bubble with a fire shielded in front and two extention behind the bubble.
