Thinking - Multiverse

So, apparently we live in one small manifestation of the universe within something called the Multiverse. This is according to some apparently excellent equations.

I don't like it.

One version of the Multiverse says that every possible version of the universe exists, and there's some stuff about a new universe popping into existence every time a decision is made. And a stack of other stuff as well.

As far as I can see, the main upshot of all this, is that people tend to talk about it a lot. I'm not so sure it makes any useful predictions or anything, but that doesn't mean it isn't true.

As I understand it, I think it's more of an inevitable side effect of some awesome equations rather than something people really want.

I know I dont want it.

I've never been comfortable with the concept because it seems a little wasteful. Just think of how much energy is required to support a universe made entirely of blue paint with nothing (obviously) that needs painting. Painting blue paint blue is a foolish errand in anyone's book.

See my problem.

But this morning I found a yellow sticky note on my screen in my handwriting that said...


"This version of the universe just so happens to be one where the Multiverse doesn't exist."


Problem solved.

Epic adventurer - DIY paracord bungee that should outlast the polar caps

Making a home made paracord* bungee** to take my new and very small Gerber Dime® multi tool on any epic adventures I may set off on turned out to be pretty worth while. Claiming that it will outlast the polar caps probably isn't saying that much.

Oh well.

I wanted to make it so I could use my new little multi tool while it was still attached to my belt so I couldn't lose it overboard, but didn't want it dangling around my ankles when I let it go without re-clipping it. I figured if I wasn't actively using it, I'd clip it to my belt, but when I was using it, I could just it to still be attached. That would mean there was a loop of rope hanging down a foot or so from my belt, and I thought that might be annoying. I have a bungee cord with a hook at each end thats been sitting in water outside in the sun for 3 years and is still in perfect condition, but I have also bought a few dozen that didn't make it 3 months. I have no idea what brand the good one is, but even if I did, it's too think for my requirements.

The invention engine said I should make my own.

I started with some paracord and removed all the inner strands. If they are tight, just pull one out at a time until they come out with ease.

The mess should look something like this when complete.

The next step was to cut a length of inner tube into a strip thin enough to fit inside the hollowed out para cord.

I cut a length around 30cm long, and around 2mm wide

Try to avoid any nicks and rough edges as this is where it will break if stretched too far.

But we wont be stretching our too far so it wont matter.

I then threaded a thin wire through the hollow  length of paracord, bent a loop, and tied the strip of inner tube to it.

I attached to other end of the wire to my house because it was the only heavy thing I could find.

With the help of some pliers to grip the paracord, it was simple to pull the strip of inner tube back through the empty paracord.

I added a decent quality swivel from my fishing gear as an afterthought, but it would have been a lot neater to incorporate it into the knot so it might lie in a straight line to the DIY paracord bungee.

As it is in this pic, I can stretch it to around twice the relaxed length.

In later experiments, I discovered that if you scrunch the length of paracord bungee into a rough ball, then roll it around between your palms as if you were rolling a ball of dough, it gains extra creases and folds. This allows you to untie it, and shorten the length of inner tube inside, and as a result bunch up the paracord.

So now I can get a stretch of around 3 times the relaxed length.

To get maximum stretch, bunch up the paracord until it's still slack when you stretch it. This means the inner tube is the limiting factor. Then let a little paracord slip through your fingers until the inner tube is still fully stretched, but the paracord is also tight.

Tie it off, and you should be set. As long as you didn't stretch the inner tube too much before tying it off, the paracord should take any extreme force that's applied, and your rubber inner should stay intact for the next 25,000 years or so.

All in all this suggestion from the invention engine turned out well.

The short length of very thin and super strong DIY paracord bungee is ideal to suspend my new favorite tool.
