Why does the pattern of galaxy super-clusters in space show fractal features?
Why do galaxies occur in clusters and chains?
Why are there spirals in sizes from superclusters, galaxies, through quasars, down to meteors?
Why do they often resemble hurricanes in shape?
Why do these spirals, even down to meteors, spit out jets of plasma?
Why do they radiate wide-spectrum electromagnetic energy?
Why do many spirals e.g NGC 7814 (see pic) resemble high-voltage arcs?
Why are some plasma jets periodic?
Why does the centre of our galaxy resemble a dynamo?
Why are the largest craters on planets and moons at or near the poles?
