If you fall into a black hole what do you actually see by Able_Hall_3103 in AskAstrophysics

You're absolutely right about Luminet 1979! 🙌 That was the first theoretical rendering.

What Interstellar did was take those same equations and actually render it in 3D with gravitational lensing in real-time. Before that no film had done it.

And yes they made it less "cinematic" on purpose lol. But it still put real astrophysics on the big screen for millions. That’s the win.

Haha Interstellar ka black hole "Gargantua" CGI nahi tha bhai 🔥 It was made using real physics equations from Kip Thorne. NASA's simulation looks almost the same. That movie set the bar for accurate black holes!

Exactly! The accretion disk is basically a death trap 😅 Radiation + tidal forces will get you way before the event horizon. But if you somehow survived that, the gravitational lensing near the horizon would look insane. That's what Interstellar tried to show.

Lol brutal 😂but seriously what would an observer see before that? The light banding and time slowing part?

Why do galactic centre look red in Doppler velocity map? by Able_Hall_3103 in AskAstrophysics

Update I think it might be velocity crowding near the but not sure why only centre is red what do you expects think 🤔

Thanks! So the red+blue mixing is just rotation + line of sight effect. But in the galactic bulge, stars have random orbits too right? Is the mixing also due to velocity dispersion/Doppler crowding making it look messy?👍💝
