Talk:2762: Diffraction Spikes
I tried to make an initial explanation, but then someone beat me to it and I made a fool of myself on the page trying to add a comment where it didn't go. I fixed it, but I am ashamed ;~; 172.69.34.15 23:31, 12 April 2023 (UTC)
- It's all good. As long as you learn from it, and we learn what useful things you want to say, nothing at all to worry about... All power to your typing fingers! 172.70.85.66 00:15, 13 April 2023 (UTC)
Exoplanets nevertheless exist because, alongside the visible diffraction spikes that chop them up, there are invisible defraction [sic] spikes that reassemble them. 162.158.158.136 00:32, 13 April 2023 (UTC)
Why does the spike slice the planet instead of the planet breaking the tip off the spike? Are the spikes like enormous light sabers? Barmar (talk) 00:43, 13 April 2023 (UTC)
- The spikes are stellar artifacts of distant observers, with all the mass of the star behind them. The Sun hardly moves much if you dunk the Earth into it, why should the exoplanet move the spike? At best you'd get a similar effect to karate chopping a stream of water from a hose. 172.71.150.175 04:49, 13 April 2023 (UTC)
Is it inspired by some movie that features this "spike pointing on some person" effect? I remember seeing one, but I don't seem to remember its name. 2659: Unreliable Connection (talk) 02:07, 13 April 2023 (UTC)
- This comic also reminded me of fractal images. 2503: Memo Spike Connector (talk) 09:06, 13 April 2023 (UTC)
- Is there also some joke here about double vision (if you cross your eyes you will see two planets), you use lens occlusion to see expolanets? (garbled)) 10:55, 14 April 2023 (UTC+1)
From an edit comment "(Refractor telescopes (using only lenses) don't give refraction spikes, reflector telescopes (using mirrors) do.)". Yeahbut, nobuf... It's just the struts, also mentioned, that are the key. You can build pure-refractor telescopes that still have struts (probably not optimal, but a design option) and therefore spikes. And you can make one with mirrors and no struts (more complicated and less of a practical shape for most mounting/launching purposes) which would therefore be spikeless. 172.70.162.160 12:00, 13 April 2023 (UTC)
