Thoughts Concerning the Origin of Our Fractal Universe
《Journal of Modern Physics》2025年第1期167-197,共31页J. C. Botke 
During the past few decades, it has become clear that the distribution, sizes, and masses of cosmic structures are best described as fractal rather than homogeneous. This means that an entirely different formalism is ...
