The universe is a fractal composed by infinte fractal dimensions.
It has been proven by astrophisics that at the center of each and every galaxy there is a black hole (what a majestic example of life/death taoistic balance).
The actual level of knowledge of human kind is only at the beginning of the path leading to full comprehension of the universe.
Based on latest phisics laws, it is accepted by science that if we sum up all the matter in the universe we obtain only 30% of the matter that is needed to justify the status of the universe as it is.
The remaining 70% of it is left in an unexplored, undiscovered and unexplained "container" called for now dark matter...
70% !!! Just think about it...we are just kids playing in the sandbox. We don't even know what there is beyond our "garden".
Interstellar travel is to humankind of 21st century as traveling the ocean has been to neanderthalians !
But the curve of knowledge is rising faster and steeper... look back just 50 years and see what it has been achieved.
Scientific research (in all its branches) must be freed from human greed (in all its forms... governments, corporations, personal gain) and used to rise humankind to a new level of knowledge and therefore consciousness.
