Can anyone help me to explain plasma to a nine year old?

So in a way 96% of the universe isnt actually missing as such it just that we havn't figured out the right equation to account for it?

I guess you could put it that way, but it's actually missing in that we don't know what it is, and considering it's 96% of the universe, that's a tad embarrassing.

We know it's "there", because we can observe the speed of distant galaxies and stuff, and we can measure the mass that they should have by what's around them, how fast they're moving, plus the light emitted and stuff, and basically everything is moving much faster than it should be, which means there's a shit-ton (Approximately 30 metric assloads) of mass that we can't account for. That is stuff we call dark matter and dark energy, because what else do you call stuff you can't find?

Would be kind of difficult, since I hate kids.

They're not 'kids'. Well, most of them are over 15, aren't they? They must be almost human by then.

Under 18, as a general rule, equals idiot.




However, observations show the following:

A) is what we predicted, showing that the outer edge of the galaxy slows according to distance from the galactic core.
B) is however what observational evidence shows, that the outer edge rotates the same as the inner edge regardless of distance from the core.



What this means is that there is a huge, huge amount of material in the galactic haloes that we can't see, and it applies to the vast majority of spiral galaxies. I can't recall the number, but I believe spiral galaxies make up the vast majority of galaxies in the observable universe, which means there's a ton of stuff we can't see. There's a similar issue with the makeup of elliptical or irregular galaxies but that's more complicated to explain.

And that's just one of the ways we know the universe is hiding stuff from us.

you struggle to find it because it is behind you

Take your juvenile theatrics elsewhere, I'm explaining the universe you goddamn cretins!
