You Don't Know Time

Huge thanks to Neil deGrasse Tyson and everyone at StarTalk!

It seems easy to know things. The basics of epistemology haven’t changed much since Plato’s time, and we navigate every minute of our lives using a system of justified true belief. If we’re justified in thinking something, that thing is true, and we believe it, then it’s knowledge.

But as Gettier Problems show us, sometimes that justified true belief model just doesn’t work. We can satisfy every condition of JTB and still not know something.

So if that system isn’t reliable, then how can we really know anything at all? It’s a philosophical problem so big that we need Neil deGrasse Tyson to sort it out.

Neil deGrasse Tyson of StarTalk sets the record straight on what knowledge really is. Science, he says, is filled with things we can truly know with confidence. Sometimes they’re things we can count; other times we just hit a limit on how useful knowledge is to humanity.

The way we view knowledge in our collaborative endeavors sets the tone for how we go about life itself -- and puts us in the best possible position to know more and progress with math, science, and humanity.

... and we FINALLY find out whether a hot dog is a sandwich.

Vsauce 1: Or is it?
Vsauce 2: Right?
Vsauce 3: (I don’t think Jake has one)

[zubadub]

Vsauce "RIGHT"
Me a veteran subscriber "WRONG"
Vsauce "WR-sometimes"

Me crying in a corner

[jonathanramsey]

How can two people both be so confident that they’re right when having reached two different conclusions is one of the best questions I’ve ever heard

[TSH]

I love what Neil deGrasse Tyson said about words and ideas. "Ideas matter... more than the words we come up with to describe them." :)

[Icalasari]

I was expecting you to go, "WRONG! This isn't a cat, this is a piece of plastic moulded in the shape of a cat"

So you managed to get me anyways

[extraterrestrialcontent]

It felt weird not hearing him scream “WRONG”

[besmart]

I can't believe Neil has a landline

[nicholas]

This has got to be the only timeline where Neil deGrasse Tyson confirms the definition of a hot dog.

[wehex]

Kevin: quick PICK HEADS OR TAILS! GO!
me: *scared* Hails

[musa]

Hahaha I got a neil degrasse tyson masterclass ad right after the “hello?”

"Social media is a venomous snake out of linguistic diarrhea and keyboard garbage"

Sounds like Twitter is getting to him.

[kuyadio]

A question that's been lurking in my mind since i was a child is...



Does Lightning McQueen has life insurance or a car insurance?

[ordinarygamergameplay]

"I haven't been outside for four months"

I know that feel V.

[blizzardphoenix]

Neil deGrasse Tyson: I have vowed to never fight about the definition of a word
Pluto: ._.

[jadenchen]

We need more people like Kevin who regularly uploads good content

“The good thing about science is that it's true whether or not you believe in it.”

[ChrisKogos]

Except for Neil, he knows everything.

[jamesrees]

I knew a cat was in this video because of my past experiences with Kevin's videos. When he pulled out the toy cat and said there was a cat in this video, I knew he would soon reveal a real cat

[doomdoktor]

Youtube: Don't use nsfw words, you'll be demonitized.
Kevin: L I n g u I s t I c D I a r r h e a
