Alexa Stop the alarm.
Hey, smarty pants. I'm so excited.
You know why? Because today is Mel Science Day.
The day Mel Science delivers a science kit right to my door.
Oh, that must be it.
Excuse me, Luna. Watch out.
Whiskers. Yeah, I got a pizza delivery for trusty narrator.
Oh, yes. Thanks. I forgot.
I pre -ordered a pizza, which I'm also very excited about.
Yes, it's my MEL Science Box!
I wonder what today's science experiment will be.
Last month, I built an awesome cable -stayed bridge, and the month before, I turned my cell phone into a microscope.
OK, here we go. Oh, this month's experiment is building an infinity cube.
Infinity cube? Infinity cube?!
What's an infinity cube?
Sounds pretty awe -inspiring.
After all, infinity means… smarty pants.
Do you know what infinity means?
Is it… Oh boy, what's happening?
whoa the roof of my house just flew off there's a giant spaceship hovering over me now a huge dude with a giant head is walking menacingly towards me I've come for the infinity cube whoa are you Thanos no I'm Ten knows as in a one One followed by 10 zeros.
Oh. Hey, I'm still one of the biggest numbers in the universe.
I mean, sure, a one with 10 zeros is a fairly large number.
Smarty pants, do you know what a one followed by 10 zeros is?
Is it A, 1 million, B, 1 billion, or C, 10 billion?
If you said 10 billion, you're right.
Like I said, I'm one of the biggest, most powerful numbers in the universe.
In fact, the universe is said to be around 14 billion years old, which means I nearly equal the age of the universe.
Whoa whoa whoa whoa whoa, hold on!
Well, ten billion is a lot, especially if we're talking about money.
It's not nearly the biggest number in the universe.
In fact, even if we were talking about money, the richest person in the world has $240 billion.
And if we're just talking numbers, there's way bigger numbers than billions.
You sure know how to make a guy feel small, narrator.
No, no, no, you shouldn't feel small.
I'm just saying there's much larger numbers out there.
And if you stick around, you can help me build my Mel Science Infinity Cube while we answer cool questions like, What is infinity?
Is infinity the biggest number?
And is there anything bigger than infinity?
Pah! I can answer those in a snap!
No! No snapping! Time for another whiff of science and history on Who's smarted?
Who's smarted? Who's smart?
Is it you? Is it me?
Is it science? Or history?
Listen up! Everyone!
We make smarting lots of fun on Who's Smarted!
It is estimated that over 4 million people have been abducted by alien lifeforms but only one of them asked for it.
This is Elio of Earth.
If any aliens are listening, come and get me.
From Disney and Pixar...
Yes, it's really happening!
He'll go where no one has gone before.
Welcome to the Comuniverse.
This is the most beautiful place I've ever seen.
This is the bathroom.
Disney and Pixar's Elio.
Rated PG. A rental guidance suggested.
Only in theaters June 20th.
Okay smarty -pants, call out the biggest number you can think of.
Did anyone say a gazillion billion cotrillian?
That was my favorite giant number growing up.
There's just one problem.
That number doesn't exist. Yikes!
Tedos, did you just snap your fingers?
No. I started putting together the Infinity Cube.
Anyway, like I was saying, some big sounding numbers are completely made up.
Don't believe me? Let's play a game.
I'll say a word, and you call out if you think it's a real or fake big number.
Ready? Go. Quadrillion.
Real. Octillion. Real.
Virgillion. Fake. Noonillion.
Real. Azillion. Fake.
Vigentillion. Real.
Mageillion. Fake. Catrillion.
Fake. How'd you do smarty -pants?
Don't worry if you got any wrong it can be tricky.
What if you got them all wrong?
I'm just saying. It's okay, Tenos.
We're learning. Okay, starting with a million, which is the same as saying 1 ,000 ,000, you've got a one followed by six zeros, and a thousand million equals one billion, which is a one followed by nine zeros.
I'm Ten -O's. Or Ten -billion.
We know there's always a 10 and 100 of each new number.
For example, 10 -billion and 100 -billion.
Ugh. Smarty -Pants, what comes after a billion?
Did you say a trillion?
Yep! Then a quadrillion.
Then a quintillion.
Followed by sextillion.
Septillion. Octillion.
Nunnillion. And a cillion.
What about a Brazilian?
Nope! That's someone who lives in the country of Brazil.
So, Smarty -Pants, you have all these big numbers with increasingly larger amounts of zeros after them.
For example, in the US, a vegetarian is a 1 followed by 63 zeroes.
Wow, that could take a while to write out.
Exactly, which is why we don't write them out.
Instead we represent big numbers by saying 10 to the power of, and then however many zeroes it is.
For example, a centillion is a 1 followed by 303 zeroes.
So we'd say 10 to the 303rd power, and we'd write it out by putting the number 10 and then next to it, a small number, 303, raised up a little bit.
Hmm. It looks like the number 10 is thinking about the number 303.
Exactly! So, smarty pants, what do you think is the biggest number of all?
Is it A, a centillion, B, a Google, or C, something else?
If you said a Google, you are wrong.
Sorry. I know what it's like to lose, to feel so desperately that you're right.
But to fall, nonetheless.
Um, yeah. Any who? A Google, which is represented by a 1 followed by 100 zeros, is certainly a big number.
Google, the search engine you might use to look things up on the internet, is actually a, intentionally misspelled version of the huge number Google.
By the way, Google the number is spelled G -O -O -G -O -L while Internet Google is spelled G -O -O -G -L -E.
I didn't come for a spelling lesson.
I came for the infinity cube.
Hang on Budget Thanos!
Google, the number, was defined in 1929 by American mathematician, Edward Kasner, and named by Kasner's nine -year -old nephew, Milton.
Hello. Really? How do you know that?
I Googled it. But as big and cool as Google sounds, it's not the biggest. Remember, a centillion is a one followed by 303 zeros.
So, a centillion is the biggest number.
What do you think, smarty pants?
if you said nope, you're right.
The biggest known number is called a Googolplex. Googolplex, that sounds fittingly huge.
Yep, a Googolplex is a one followed by writing zeros until you get tired.
Kidding, that's an old math joke.
The truth is you can't write out a Googolplex. Of course I can.
I'm Tennos. I am inevitable.
And also capable of writing out big numbers.
Nope. Despite knowing that a googolplex is a one followed by a googol zeros no person or computer in the universe could ever write it out in full.
That's because there isn't enough room in the entire universe to write down all the digits in a Google Plex. Whoa.
A number that's bigger than the universe, I must possess it.
Good luck with that.
But here's the crazy thing.
We also know that an infinite amount of even larger numbers exist. What?
For example, Mathematician Ronald Graham came up with a number in 1971 known as Graham's number That's even bigger than the googolplex. While it too is also literally too big to write.
We know this number is divisible by 3 and ends in a 7.
Let me guess you googled that too?
I sure did. Okay, enough with other large numbers.
The biggest number in existence is the one I came for.
Infinity! I'll tell you the answer right after this quick break.
Make it snappy. No!
No snapping. Psst, hey, smarty -pants.

Hey, smarty pants, Trussty here with a special mission for all the smarty pants listening.
But unlike a top secret mission, this mission requires you to tell everyone.
That's right. Your job is to spread the word about who smarted so we can keep growing and bringing you awesome new episodes.
To qualify for this mission, let's play a little game.
Who do you know that would love who smarted, but doesn't listen to the show?
Is it A, a friend? B, a teacher?
C, a relative like your favorite cousin?
Or D, a neighbor who loves fun facts?
Got someone in mind?
Great. Question Two.
Where and when will you tell this person about who smarted?
Is it A. on a playdate?
B. at school? C. in the car?
Or D. on the phone?
Pick one. Make a plan.
Stick to it. And best of all, complete this not so top secret mission.
I'm counting on you, smarty pants.
The more people you tell, the bigger we grow, which means a lot more smarting for you.
Now back to who smarted.
According to my new friend, Tennos, the largest number in existence is...
Infinity. Infinity is the largest number, and once I posses the Infinity Cube, I will, in effect, posses Infinity.
Well, I'm going to have to stop you right there.
You think you can stop Tennos?
Oh, not just me. The Avengers?
Are they going to assemble to out math me?
I mean, Tony Stark's pretty good at math.
So's Bruce Banner. But they can't outnumber me once I have the Infinity Cube.
But that's just it.
Infinity is not the largest number.
Are you saying there's something larger than infinity?
No. Good. There's nothing larger than infinity.
However, infinity is not the largest number.
That makes no sense.
Smarty pants, do you know why?
It's because infinity isn't a number.
Then what is infinity?
Infinity is an idea.
An idea of something without an end.
It cannot be measured and it's not a number.
Reality is often disappointing.
Smarty pants, do you know what symbol is used to represent infinity?
It looks like a number you all know, only lying on its side.
Is it a three, a six, or an eight?
Did you say an eight?
Great job, infinity is represented by a figure eight because it has no beginning and no end, it just goes on, and on, and on, and on.
So it's growing. Nope, infinity is already fully formed.
Infinity doesn't do anything, it just is.
Smarty Pants, true or false?
Infinity only relates to large numbers.
The answer is false.
Not only are there an infinite amount of larger and larger numbers, but there are also an infinite amount of tiny numbers that are close to zero, but not zero.
The word infinite is related to the word infinitesimal, which means immeasurably small.
I see. So there is a balance between big and small numbers.
Yes, but that's not all.
Smarty Pants, how many numbers are there between one and two?
Did you say none? Some of you might be thinking of fractions or decimals like 1 and 1 .5 or 1 .5.
That's great. But guess what?
The answer is there is an infinite amount of numbers between one and two.
Whoa. For example, there's 1 .1, 1 .11, 1 .111, 1 .1111, and on, and on, until the universe is entirely filled with ones.
I want them. I want all those ones.
Sorry, you can't have them all because there's no end to them.
So now what? Narrators, assemble this infinity cube from Mel Science.
Oh. This cube is filled with little lights that seem to go on forever.
No matter which way I turn the cube, it looks endless, limitless, infinite.
It's also a cool little lamp.
Ooh! Tell you what, I'll give you a choice.
The hardest choices require the strongest wheels.
Right. You can either have the infinity cube or I'll sign you up for MEL Science so you can get your own infinity cube and lots more awesome science delivered right to your door or spaceship or wherever.
Really? Just like that.
Yep, it's a snap. Hey, half my pizza's gone.
I ate it when you weren't looking.
