using only the ten hundred words in our language that people use the most.

Going to space is hard.

First because the Earth pulls things toward it,

so not only do you have to fight the Earth's pull to get to space,

you also have to go really fast to the side, so that when you fall back toward Earth

you miss and go around, instead.

That's how you stay in space.

The best way we know of to get to space and stay there

is an up-goer that burns fire-water,

usually made from all dead animals

or the kind of air that once burned the big sky-bag, and people died.

The burning fire-water hits the inside of the up-goer so hard

that it pushes the up-goer up.

Actually, it pushes the up-goer away from where the fire comes out.

If the fire-end points toward space, you are having a bad problem,

and will not go to space, today.

There are often several fire-water burning parts to an up-goer,

so that after you use up the fire-water in one part,

you can drop it, and don't have to lift it all the way to space too.

Space is cold and has no air,

so if you want to go to space and live,

you need to be on an up-goer that has a room for people in it, usually on top.

This room has heaters, and air, and no holes, so that you can stay alive,

and a window, so that you can enjoy looking at Earth from space.

It also has a thick side, so that if you want to come back from space,

you won't burn up from all the air you hit on the way down.

Hitting air helps slow you down a lot,

but to help slow down even more, there are big sheets to catch air too,

so you don't hit the ground too hard.

We humans pretty much always have several up-goers almost ready to go to space.

But if you try to get in one of them, a lot of people would get really mad at you,

and you'd get in trouble and probably go into a locked room behind bars.

If you want to use an up-goer to go to space instead of into that room,

you have to have many important people say "OK".

Before they say "OK", you have to prepare to go to space for many years.

If you want to be like many people who went to space in the past,

you should go to school to learn to fly sky-boats, and be really good at it.

You also need to be able to see and hear very well, and not get a sick body or head.

There are many other things you need to be good at, too, and you need to be lucky.

But if you're good, and lucky, and all the important people say "OK",

then maybe you can go to space someday.

Thanks for watching. If you like confusing stuff explained in simple words,

you'll probably like the book "Thing Explainer"

by the man who wrote the picture story, XKCD, and the book called "What if?".

You can find "Thing Explainer" at book stores,

or by using your computer to search the place where many computers think together,

or by looking in the words below this computer movie.

I also want to add that I am a huge fan of XKCD and...

I'm just super excited to be able to make this video.

You should definitely check out "Thing Explainer" if you're into XKCD,

it's a great book, it's really fun, the drawings are really fun to pore through,

and Randall's done a great job with it,

it's beautiful. And if you like this video, this style of video,

please, let me know, share, I'm excited to see what you think.

Thanks for watching.
