Not all of us with dyslexic learning disorder I put a lot of time into listening to you your very smart 😉 I thank you for speeding up my learning rather than learn 🙂 something not followed
I wonder why Zwicky didnt call it transparent matter. Dark interacts with light: it absorbs it. therefore it becomes dark, therefore it is opaque. While Dunkles Materie is invisible, absolutely transparent, and this quality is what haunts the scientists and also us, the laymen.
Am I correct in saying that, given the data, it looks like the dark matter density increases with the distance from the nucleus? Sort of like how a mattress will lift up around your body when you lay on it, the dark matter increases *around* baryonic matter?
Not quite. Dark matter is distributed much more evenly. It’s “hot” dynamically, and it has a hard time losing energy of motion (kinetic energy) because it doesn’t interact with light (electromagnetic interaction). Therefore it stays spread out and the density doesn’t drop off as fast as the regions which emit light.
@@JasonKendallAstronomer lol, I suppose so. 😆👍 I'm learning. It's just hard to take some things as given. Which is why I'm trying to learn the math at this later stage. I gotta know, ya know? Thanks Prof, for being here.
Stellar black holes are hard to directly detect, couldn't dark matter just be a mix of all the hard to detect objects in greater than expected quantity? If our tech can't 'see' it then it must be dark matter doesn't seem like a scientific explanation for making the extraordinary claim of a new substance all that strongly.
Is far as i know, the number of black holes required would be fare too large. But there is always the possibility that there is not excess mass, but some flaw in our calculations.

Very interesting. Thank you professor.

I always thought it could've ben namd "Doesn't Matter" or auf Deutche "Matter Nicht".
@@JasonKendallAstronomer LOL you are funny!
Wow great stuff.

27:13 NOBOKs. (nobody knows' s )
I don't have the math, yet, but doesn't dark matter smell a little bit like luminiferous aether?
Can’t you smell that smell?
Skynyrd likely knew something about luminiferous aether.

Those are called MACHOs and searches have been done. They do exist, but they are not in great enough amounts to account for the missing mass.
