This is my attempt at a straight-up Star Wars one: http://lmnopc.com/mf/ http://lmnopc.com/mf/ I made this dumb thing like seven years ago based on a CSS starfield codepen that was floating around: https://codepen.io/noahblon/pen/GKflw https://codepen.io/noahblon/pen/GKflw

That's neat, I always wonder how accurate are the sci fi depictions of galaxies and what not becoming lines.

  I'm not sure what you mean by "accurate", since all of the interstellar drives that appear in sci-fi depictions are inconsistent with our best current understanding of the laws of physics.

    So that's a no (not accurate). Looks like you just see a faint glow/ball of light. I saw something about when you travel near speed of light, lengths appear to contract. Maybe the lights becoming lines is just based on long exposure in photography of moving lights.

      > I saw something about when you travel near speed of light, lengths appear to contract "Appear" in this context, though, doesn't mean "what you actually see". What you actually see is an apparent rotation of an object moving by you at relativistic speed. This is called Penrose-Terrell rotation: https://en.wikipedia.org/wiki/Terrell_rotation https://en.wikipedia.org/wiki/Terrell_rotation Note also that the effect is only along the direction of relative motion; appearances transverse to the relative motion are unchanged. > Maybe the lights becoming lines is just based on long exposure in photography of moving lights. I think the "lights becoming lines" in sci-fi depictions is based on a Newtonian picture of what things would look like if you were moving through a space filled with stars at a speed much faster than light. Which of course has nothing to do with actual physics as we understand it today.

        Here's a demo of that effect, again via WebGL https://harrygifford.github.io/special-relativity/ https://harrygifford.github.io/special-relativity/

As soon as I said "Punch it!" Android 10 (Firefox 91.4) crashed. Haven't seen that happen before :)

  same for me, this website crashed my phone. Android/Firefox

    Bromite runs it, but my Firefox Focus also rebooted the phone. Somebody should debug this.

      The site is super slow on desktop Firefox on macOS (and fine in Chrome and Safari). I don't have Firefox for Android, but there's probably a connection. I filed a Firefox bug for the performance problem and mentioned the Android crash: https://bugzilla.mozilla.org/show_bug.cgi?id=1732608 https://bugzilla.mozilla.org/show_bug.cgi?id=1732608

Nice! Did anyone do a Star Trek one for TNG/DS9/VOY/ENT? Most of the ones I saw in the past were only half-correct - they did the "stars moving in streaks parallel to your direction of motion", but did not replicate the "individual streaks show Doppler-shift-like colors". (See e.g.: https://static.wikia.nocookie.net/memoryalpha/images/d/d8/USS_Rio_Grande_tractors_the_Orinoco.jpg/revision/latest/scale-to-width-down/520?cb=20050308150342&path-prefix=en https://static.wikia.nocookie.net/memoryalpha/images/d/d8/US..., notice the color bands on the "stars".)
