Let me try with a very few words to explain the basics of fractale. Be sure that you'll entry an existing amazing world of which you didn't expect that it's since all time part of your reality.
The basic concept of fractale is commonly known by a form which is called Mandelbrot, Julia Mandelbrot or Apfelmännchen. As more you dive into this grafic model the samples of this form repeat again and again. It's in any way as if you are stationed outside this universe and explore with an imagined telescope with endless magnification possibilities the viewpoint in direction earth.
At first you see the solar system. Diving deeper you recognize the surfaces of the planets. Then you see the planet Earth, note the oceans and continents. You realize deserts, woodlands and mountains, ..... cities, villages, moving traffic. You realize that there are human lifeforms ..... which have different skin tones. Diving deeper under the surface and skin you can see their organic inside, the veins which will invite you to follow them a little bit and explore different rooms of the body. But your magnification possibilities don't stop. Diving deeper you will discover molecular structures, nucleus and things which are much smaller.
Looking around in this magnification you remember that your real point of view location is outside the universe, ...............
.................. and suddenly you note that the deepest insights show you the same samples as if you look ahead to the outer stars and explore the quite other direction.
Isn't it spooky ???
