Dark Matter = Fred 🤣 w/ Neil deGrasse Tyson

[Weary]

I love how they agree on calling it Fred, but then never refer to it by that name for the rest of their conversation

[uthred]

“Jamie, pull that video of a grizzly fighting over a dark matter named Fred”

Back in the 1980's we used to call it the "missing mass problem".
Back then, we didn't know that it was 20+%, all we knew was that there was more gravity than we could so far account for.

We haven’t unlocked that part of the universe yet.

[SayNoMoore]

I love how Rogan acts like he knows what he is talking about, and Neil is getting more and more aggravated trying to correct him 😂😂

[galaxysolace]

My manager is named Fred... Ill call him dark matter from now on.

[ThePinkBlowfish]

Neil needs to do a long video explaining dark matter in words we all can understand going into great detail about it

[havefunoutthere]

Absolutely LOVE these conversations. Thanks for posting.

[UnderAlog]

Neil makes me feel like im smarter than how stupid i am

[ahseaton]

The original observational "problem" that was "solved" by inventing "dark matter" was that galaxies don't rotate "right". The outer stars in the galaxies rotate too fast, given the observable mass of stars and dust, etc of that galaxy. They rotate as if the mass of the galaxy is several times heavier than it "should" be. However, the gravitational forces at those distances from the center are very weak. They are around 10^-34th what they are at the galaxy center. That order of magnitude is significant because that is the level that quantum effects start to occur. So, "dark matter" may actually be due to the effects of "quantum gravity" which nobody has been able to formulate, much less agree on. This is all made worse because gravity is already 10^-36 times weaker than electromagnetism.

Sometimes I feel a little cranky about Neil's answers, but in this case he is spot on point. Nobody knows what the heck this stuff is, or even if it is stuff. Kudos to Neil for calling that out clearly!

[lancevoorhees]

Neil always makes sense! Love his videos!

[Oziel]

The amount of times they interrupt each other 😆

[dubstepsiik]

Joe cant ask a question without even getting interrupted lol

[iwarx]

I like how he doesn’t know a sh*t about “Fred” and when Neil is trying to explain it he just interrupts him immediately

[markphilips]

If you picture the universe as a great collapse as opposed to a big bang, then maybe what we see as "Fred" is really everything collapsing into a universe that is the singularity of a black hole.

[mattshuey]

I'm going to use that for any question I don't want to answer.
"I'd like to just call that Fred for now."

[nimrodlevy]

Its not even dark, its transparent gravity.

[stormmeds]

but the fact is if you send Fred to school and learn the human value system and raise him to serve. Fred could serve forever

[altair]

Dark gravity= stuff are moving and we don't know why
