Electric Universe theory explains most, if not all, of cosmological phenomina observed without the use of undetectable and unprovable contrivances (black holes, dark energy, dark matter, etc).
Electric Universe theory will also explain many terrestrial and extra-terrestrial geological phenomena.
Electromagnetic forces are many orders of magnitude more powerful than gravity, and do explain what we see quite nicely.
Spend a little more time with it before you dismiss it as "crackpot".
Usually if a seemingly good idea isn’t accepted there’s a good reason why.
Especially if a whole lotta people are looking for the solution for a long time.
The paper looks more like an senior undergrad “pick a subject” research assignment, spending lots of time reviewing basics before moving on to sort “hey this is neat” applications and borrowing random pictures from popular sources.
