Successful predictions attributed to the Plasma Universe (and Plasma Cosmology), and its pioneers and proponents, are considerable. These are just a small sample.
- Predictions attributed to Hannes Alfvén by Professor of the History of Science, Stephen G. Brush, include:
- Magnetic braking.
- Magnetohydrodynamic waves (Alfvén waves)  
- Field-aligned (“Birkeland”) currents 
- Critical ionization velocity .
- Rings of Uranus (predicted by Bibas De) 
- Jet streams  
- Electrostatic double layers  
- Partial corotation (“2/3 effect”)
Dr Anthony L. Peratt notes:
- Background radiation in the X-ray, gamma-ray, and infrared regions: “The discovery of background radiation in the X-ray, gamma-ray, and infrared regions was unpredicted by the Big Bang model and was the first in a long list of “surprises” which theorists then sought to incorporate into that cosmology. Unfortunately, the ad hoc explanation of observations not predicted by a theory rings of Ptolemy’s epicycles.
- In contrast, the Plasma Universe model welcomes and seeks ever more data from the entire electromagnetic spectrum, from extremely low frequency radiowaves with wavelengths of kilometers or longer to gamma rays with wavelengths of 10-13 meters. This requirement arises because plasmas are prodigious producers of electromagnetic radiation.”
- Large-scale structure: “The prediction that the universe should have a cellular and filamentary structure at the large scale is a major difference between the Big Bang and Plasma Universe models.”
- Filamentary, magnetized structures in our galaxy: “Since the plasma model assumes that the properties of plasmas are the same throughout the ranges of sizes from the laboratory to the cosmos, a model has been developed based on processes verified in the lab and observed on the Sun which predicts that plasma filaments should be found at the center of our galaxy.”
- Magnetic fields in galaxies: “In early 1984, plasma simulations of galaxies suggested that highly ordered magnetic fields stretching for tens of thousands of light years should exist in galaxies.”
- Rotational velocities of galaxies: “The only way to explain this characteristic in a gravitational system is to postulate large amounts of unseen matter in the form of a massive halo about galaxies. Plasma simulations show that electromagnetic forces, which are 39 orders of magnitude stronger than the gravitational force, are central to the dynamics of galaxy formation. Using the observable mass of a typical galaxy, about 100 billion suns, the plasma simulations replicate the rotational curves of spiral galaxies.”
- Cosmic Microwave Background: “One of the serendipitous but extremely significant discoveries of the Plasma Universe simulation model was a background of microwaves with an energy density very nearly equal to that observed from the cosmic microwave background.”
