B”H

Can you imagine that no one has an explanation for 96 % of the universe ? Only 4 % of the universe consist of galaxies, planets and stars. The other 96 % consist of “Dark Energy” and “Dark Matter”. We are neither able to feel nor to comprehend those two “existences”, "causes", “substances” or whatever you would like to call them.
