Chatted with a guy at the observatory open house last weekend

I was at the university observatory here in Austin and a retired physics teacher pointed at a blurry photo of the Andromeda galaxy I took and said 'this is what dark matter looks like, just a ghost of mass.' He explained how the rotation curves don't match what we see, and it kinda hit me that most astro photos are showing something invisible too. Does anyone else feel like we're just taking pictures of empty space and calling it science?

Wait, you're saying the empty spots in photos actually tell us more than the bright ones?

Bought a cheap telescope off Craigslist and spent a whole night trying to get a clear shot of the Orion Nebula. Ended up with this fuzzy blob that looked like someone smeared cotton candy across the lens. But knowing that dust cloud is birthing stars and the dark parts are hiding stuff we cant even see yet, that changed how I look at every photo now. Its mostly empty space with a few bright spots, but the empty parts tell the real story.
