What Is Dark Matter? Neil deGrasse Tyson Tries To Explain

Neil deGrasse Tyson is a renowned astrophysicist who can explain just about everything related to science and outer space. Well, except for one thing.

"Dark matter. I get asked what it is. And my best answer is we haven't a clue. We don't know what it is," Tyson tells us.

The StarTalk Radio host does his best to explain dark matter and why it's such a complex subject.

I'm all in for calling it "Fred"

[joedotphp]

"There's gotta be some ass.  Where is it?  We can't find it."  Laughed so hard.

[nichirh]

I just love this man, he explains complicated concepts in a way that anyone can understand them! Thanks for being in this universe NdGT

[leopold]

In a nutshell: We don't know what it is but it must be there bcs all the visible things in the universe don't add enough mass up for the gravity we're seeing

[VorsaLjanta]

Sorry Freds of Earth, you have no meaning.

[pranav]

Just a random thought...what if Dark Matter is really luminiferous ether?

[boldsign]

Maybe it's gravity from another dimension.

[jerilloyd]

Out of the many brief explanations I've found of dark matter- this explained it to me the best!

[SoccerBoyAP]

I actually prefer to think of it more like "missing matter" then dark gravity or dark matter.

[RecentlyAdults]

Every Fred I know is mysterious, so it's quite fitting.

[ShannonLooper]

"Extra gravity" would be totally honest. I got $10 that says we got our "mass causes gravity" concept wrong. If the observation doesn't fit the model, the first thing to suspect is the model.

[lewisner]

I would love to find out what it was and casually mention to him "oh I know that".

[sexybeast]

I had a thought that dark matter is matter, but just in higher dimension so we can't see it. Gravity still mathematically works if we include more dimensions so it affects that matter as well. Going all the way up to 11 dimensions could explain why there is so much more dark matter than regular matter, that we see.

Imagine 11 transparent sheets of papers and on every one of them stars and galaxies are drawn. If you put them all together, forming one sheet of paper, you get how universe actually looks like, but we are prisoners of 3 dimensions so what we actually see are only 3 sheets of papers, .. our regular matter. Other 8 dimensions are unkown to us and only connection with them are black holes and gravity.
That's how i imagine it

[Spiralsmile]

It's so curious to me that someone with the personality of neil degrasse tyson also had the personality of an astrophysicist

[iWpanz]

It is the mechanics behind the mulitversal computer that is running this simulation which is the universe we are in

[Wowyana]

There's gotta be some mass somewhere! Get it?! Some mass! Lmao!

[FlemingoFilmProductions]

people named fred after this: 🚗 🛣🚶🏻‍♂️📉

[swardist]

Well seems like a fucking good explanation to me.

[Campiclatch]

Dark Matter: "We should call it Fred"

[Atlas]

Just call it "the unknown thing" Neil.
