dark matter is not a theory

dark matter is not a theory.

I tried to increase the sound on this---let me know how it went? I keep getting comments that my sound is too low but it always sounds fine on my devices.

Dark matter:
Do we need it?
What is it?
Where is it?
How much?
Do we need it?
Do we need it?
Do we need it?
Do we need it?

POV: You're about to add an 'other' comment, thus changing the data until that which was presented in the second video is inaccurate for the future, thus aging it like milk.

There's sometime therapeutic about "Dark matter isn't a theory, it's a list of observations"

[comment_section]

as a retired engineer who's good at math but doesn't really understand this, you must be wrong.

Dr Weinberg was my professor for cosmology, and he gave us a flawless performance of the dark matter rap during lecture. He got a standing ovation. It was effervescent and hearing that at the beginning of this video made my day

The fossil analogy was actually perfect! Fossils aren't the actual organisms anymore (ignoring stuff trapped in amber etc), but give us a detailed picture of what the bones (and sometimes skin and feathers/hair) looked like.

I'm not a student, engineer, chemist, or scholar; I'm a truck driver with a high school education. I just want to say I love your content. Your ability to communicate is wonderful and make the topics more interesting.

Someone in the comments unironically just said "Thank you Physics Mommy"

I was just trying to explain this to my son earlier (who's 6) and told him that while we haven't figured out what dark matter or dark energy is, we can observe the effects of it. He had far too many questions though. I study computer science, not astrophysics, so I had to basically tell him I just don't know enough or understand enough to give him better answers. I think admitting "idk" is unfortunately lacking in society. Anyway, maybe one day he'll be able to explain it to me!

I love finding new educational channels with personality. Love the casual vlog style and your vibe, subscribed

It's funny: some creators use these powerful engines and elaborate animations to try and convey complicated topics more intuitively. You simply talk to us like we're in a conversation, using your hands and the occasional picture, and I always end up with a clear and manageable (even if not totally complete) understanding. You are an amazing communicator! Thank you for your content

8 questions to ask yourself about dark matter:
1. Do we need it?
2. What is it?
3. Where is it?
4. How much?
5. Do we need it?
6. Do we need it?
7. Do we need it?
8. Do we need it?

"so this is when we- well not us, we werenyt there...this was before stars..."

Something about this line is just hauntingly beautiful and terrifying to me

[Binyamin.Tsadik]

I like that you included the point about the systematic error.
That the expectation vs measurement does not have the same discrepancy in every galaxy.
Very important addition.

This got unexpectedly very emotional for me at the end. Today was the funeral of an aunt of mine, who was one of the best hobby gardener I know. And as a matter of fact I told the people who were there how honoured I feel to have all her gardening books now here at my place to take care of them. And it was also a rough day because we couldn't take my dad with us who is at very poor health both physically and mentally. And coincidentally to how you ended your video my dad has been a ham radio enthusiast for 30 years. So very strangely I feel like somehow if I have been hugged by this video and it somehow makes me want to hug it back. This must sound strange... but I feel very strange after watching the end of your video, but actually a lot better. Just had to have you know that.

What if the next spike on this video is from your own video? 🤔

Love your crusade against the use of plots/graphics that are incomprehensible or given no explanation.

I don't hate when you repeat stuff. You are (a) making a stylistic choice which is fun and (b) making things easier to understand. I get it, and please keep doing it

Takeaways from this video:
1. Dark Matter is not a theory
2. Dark Matter is an observation
3. You can't just throw away Dark Matter
