For years now, scientists have been trying to find the elusive "dark matter," which they claim comprises over 90 percent of the universe.
They are also seeking the answer to why the galaxies are accelerating outward instead of slowing down from the big bang.
It just so happens that their dark matter is a globe of water surrounding the heavens.
It is the mass contained in this water that is providing the gravitational pull on the galaxies, causing their acceleration.
It is also possible that this water has frozen into a solid dome and, therefore, cannot collapse on itself. This would then provide a stable frame of reference until the galaxies reach it and their energy starts to melt it.
This approach not only makes sense logically. It is described in the very first chapter of the greatest textbook ever written.
