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'.
One primary unanswered question about the origin of the universe is what caused the Big Bang. Another question is what existed before the Big Bang and what, if anything, lies beyond the observable universe. Additionally, the nature of dark matter and dark energy, which make up most of the universe's mass-energy content, remains a mystery.
Stardust refers to the material ejected from stars, primarily composed of elements like carbon, oxygen, and silicon. Dark matter, on the other hand, is a mysterious form of matter that does not emit, absorb, or reflect light, making it invisible. While stardust is a known component of the universe, dark matter is hypothesized to exist based on its gravitational effects on visible matter. Their relation lies in the fact that both stardust and dark matter play significant roles in shaping the structure and evolution of galaxies, though they exist as distinct entities.
Beyond the stars lies the vast expanse of the universe, which includes countless galaxies, cosmic structures, and phenomena that we are only beginning to understand. The observable universe is filled with dark matter and dark energy, which make up most of its content yet remain largely mysterious. Beyond the observable limits, the universe may continue infinitely or lead to other dimensions or realms that we cannot currently perceive or measure. Ultimately, what lies beyond the stars challenges our understanding of physics and the nature of existence itself.
Dark matter, matter, and antimatter are all components of the universe, but they have different properties and interactions. Dark matter is a mysterious substance that does not emit light or energy, but exerts gravitational force. Matter, which includes everything we can see and touch, is made up of atoms and particles. Antimatter is a mirror image of matter, with particles that have opposite charges. The relationship between these three components is complex and not fully understood, but they all play a role in shaping the structure and dynamics of the universe.
The fundamental difference between light matter and dark matter in the universe is that light matter interacts with electromagnetic forces and can be seen or detected, while dark matter does not interact with light and is invisible, making it difficult to detect directly.
If it lies in a plane, it is a decagon.
The universe is defined as all matter, energy, space, and time. As such, there is no "beyond" the universe in traditional terms, as it encompasses all of existence. Speculation about what lies beyond the universe is purely theoretical and currently beyond the scope of scientific understanding.

In astrophysics, geodes are used to study the effects of dark energy on the curvature of spacetime. Dark energy is believed to be causing the accelerated expansion of the universe, and geodes help scientists understand how this mysterious force influences the geometry of the cosmos.
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.
