why are galaxies and solar systems always shown as being disclike?
Because elliptical and spiral galaxies are common.

Check
this out Tuggy :)
" both the matter that collapses to form a galaxy and that which collapses to form a star or planet must conserve angular momentum. In doing so, disks are formed. "
Now what the f* is angular momentum?
Check
this outAnd now you can make even better questions :)

Spiral galaxies are formed after ejection stars and planets from equatorial plane of parent stars (starburst nucleus).
Proof is in the excellent research;

K Margiani makes a valid statement, and also with elliptical galaxies are generally created after the cyclonic merging of multi remaining spiral galaxies. This is know as "galaxy cannibalism" Its a very involved subject matter with many contributing factors. We could go on...

The solar system isn't entirely disklike (which suggests it is relatively young).
Pluto and several other so-called dwarf planets orbit the sun on orbital planes drastically different than the 8 planets. There are also millions, and possibly even billions of comets that orbit the sun at very drastically different angles.
In a very old solar system, you would expect virtually everything, not just major planets, to orbit along the exact same plane.

So is it that they orbit on a disk or do some have orbits like electrons around their atom?
