It is being speculated that at the centre of our galaxy is a super massive black hole, its gravity is not just spherical but it has a central plane, like a flat disk. Hence, why the galaxy looks like a flat rotating disk. Could passing through this central plane cause a pole shift if our part of the galaxy past through it?

In evolution, species change and mutate in to different species to adapt to the new environment. But how does your body know what to keep and what to change. Like how does the body know what to evolve into? Do genes have minds of their own and they know when they are needed or not? Or is it that the body knows which part of itself is not being used well and gets rid of that part and the parts of the body that is being used constantly tells the body that they need an upgrade?

Some one enlighten me!
