I like to daydream around hard challenges.

I don't know how to build a spaceship.  But maybe it would be fun to try.

To make it harder, let's make it out of only something ridiculously hard to do it with, like toilet paper, or leaves, or old newspapers.

I don't know what kinds of problems one runs into when building a spaceship, but when I start planning it I think the first problem will be getting something to go really, really far against gravity.

Another problem I hear about is burning up as you accelerate through the atmosphere.

I imagine aiming what direction you go in is pretty hard too.

I'm thinking I'm probably okay with there being some guidance computers and robotics on the craft, but that we would _mostly_ make it out of tissue paper or whatnot.  Making computers out of tissue paper can be considered a separate problem, for now.

One way to make tissue paper move is to burn it.  Could we use a tissue-paper-fueled rocket to accelerate the craft?  Almost certainly not, but doing the calculations for this could inform what thing to consider next.

I have no idea how to make a rocket, or how rockets work, but I imagine that when you burn something, it turns into gas, and the expansion of the gas is much larger than the thing you burned, so if you direct this gas in some direction or another, it might push something further. I dunno.  Like getting up from a chair because of a fire you sat in.  Maybe?  I dunno.

Maybe I'll briefly websearch for "solid fuel rocket" and see what I get.

Oh, great, this is a very well-studied thing.  https://en.wikipedia.org/wiki/Solid-propellant_rocket .

I'll read the "Basic Concepts" section.

Huh, they mix the fuel with oxidizer in advance.  Early rockets couldn't be turned off, after being ignited, until they burned up.  Anyway mixing the fuel with the oxidizer would make design _so_ much easier.  I wonder how thrust is calculated.

I'll click around some.

I'm saving this as a draft.  The 'cocky' attitude I post with on this list is an affect.  However, I'm noticing that posting this, it appears that I might only need knowledge to accomplish things, which could scare people wanting to control me. Maybe that's why it is so hard to do even the smallest thing in my life.  Unsure.  Also unsure why I post.  So, draft.
