Okay look… the big bang has happened more than once according to string theory. To explain it, picture a two sided vortex. much like an hourglass. Now the thing is… it spins around and wobbles because it is in outer space. Much like a cantaloupe in water, in a running river being pushed by one ocean between two seas. This is called particular gravity waves. They were just proven to be true. Also known as particle gravity waves according to a Nobel prize winning observation and research the ten empirical values. Based on the higg’s bosom explosion, implosions. Meaning there is a small universe within our universe, and therefore a large one, it is not a multiverse, it is a multidimensional universe… this is dimension, sizes and all that. Well in space, a similar particle matter known as dark gravity exists. In between this photon energy occurs between stars (called gamma rays in theory during the 50’s and 60’s). Think of them as stones in the bottom of a river for simplicity sake. That does not mean some do not protrude near shallow water by the river’s beach. Well the way it works is that there is a series of tiny things much like midichloreans in star wars for those sci fi fans. But that suggests water in outer space, which does exist on some frozen comets and the smallest planet in our solar system Pluto. You can call it a dwarf planet if you will. Anyway, not to stray off topic, well gravitational fields are found in space, think of it as a heaven’s wind. This causes planets to spin and when something is spinning so fast, it can cause a suction like effect, hence why we don’t float away, it also has to do with our mass as a human body as other animals can fly to high elevations even to the moon… of course they are frozen over and it would be hard to revive them but that is beside the point, there is still bacterium on the moon. Not necessarily germs but healing form of water mixed with dirt through wind but compacted by the impact on earth and the gravity of the sun along with the nearest two planets for a start. I’m straying off topic, but with this simple knowledge, it means… essentially a black hole is sorta like an hourglass that has an opening where sand does not pass but clearly air and gravity does despite it being sealed. Other wise the sand would stay in place. Depending on the size of the stars around it can pull up like an hour glass that is diagonally held. Once in awhile some sand bounces up to the other side of the hour glass. This effect is similar to a rubber band that is pulled back and flies forward as I had stated before. Of course, this effect is hard to see visually as the wind would be like the other grains of sand which vary in sizes through clumps on an hourglass while the speed at which it falls causes some to rise on the upper side of the hourglass. It seems everything is stuck in one place, but it is expanding beyond the hourglass. That is like the vortex effect that keeps the universe expanding as there is something small growing into large and something large growing into apparent nothingness, yet it is not nothing. It is not necessarily based on a collision, but rather a symbiotic effect if you will… hahaha. More so a pairing effect between photon particles based on light spectrum and gravitational waves based on sound or vibration.
