We know that dark matter exists because it got gravity, though it is invisible. It hold galaxy and Universe.
There is a theory there many other parallel universe outside our universe and dark matter holds those universe up and some scientists says that dark matter are just mass of the matter of the parallel universe. It sounds crazy but that is the Law of Physics.
However there is not exact explanation of what dark matter really is, so there are still Noble Prices for those who can come up with a reasonable explanation.
Weird thing is, there are many other parallel universe, so there is someone like me from another universe typing this answer and there is someone from another universe that is the same as you read reading this right now, man that is creepy.
So what lies on the edge of the Universe? Another parallel universe. And the theory for that is 'String Theory' and 'The M theory'.
If it lies in a plane, it is a decagon.

There is probably be nothing more than comets, dust, and dark matter until you reach another solar system.

What lies beyond the boundary of the observable universe can not be known.
In a very simple sense, scientists like to believe that the universe if "symmetrical". That is, there should be equal amounts of matter and anti-matter. However, there is obviously more matter than anti-matter in the universe, and Scientists believe that the answer to why this apparent "asymmetry" exists lies in particle physics. I would recommend reading the book "Supersymmetry : Unveiling the Ultimate Laws of Nature" by Gordon Kane for further explanation. Other reasons why the study of small particles will help us understand the universe is that there are predicted particles, such as the Higg's Boson, which could explain the properties of the Universe itself. In this case, it is believed that the mass of all particles arise from the interaction with the Higg's Boson. All these things are explained in this book.

Antarctica is the only continent that does not have any edges meeting a plate boundary. It lies entirely within the Antarctic Plate.
