Re. Dark matter. Concept of nothing

In summary, the conversation discusses the belief of many physicists that there must be a structure to the vast voids in space, despite it defying basic principles of physics. The structures are not theoretical entities and are measurable. However, the forum is not for debunking alternative theories and only focuses on mainstream physics.

"Why do so many physicists believe there has to be a structure to the vast voids in space" ?

Surely, Their thinking defies the basic principles of physics, i.e. in order to have something
there has to be nothing ! to have a positive there also has to be a negative, so as for the positive to function !

“Can someone explain why not” ?

Hi Philip Carvey,

This forum is dedicated to helping people learn and understand mainstream physics as practiced today by professional physicists. It is not for debunking alternative theories. We can discuss "Explain why theory X says Y" but "Explain why not" is out of scope.

1. What is dark matter and why is it important in science?

Dark matter is a hypothetical type of matter that is believed to make up about 85% of the total matter in the universe. It does not emit or absorb light, making it invisible to traditional forms of detection. Its existence is inferred from its gravitational effects on visible matter. Understanding dark matter is important in science because it can help explain the structure and evolution of the universe, as well as the formation of galaxies and clusters of galaxies.

2. How is dark matter different from regular matter?

Dark matter is different from regular matter in several ways. Firstly, it does not interact with electromagnetic radiation, which means it does not emit, absorb, or reflect light. Secondly, it does not interact with regular matter through strong or weak nuclear forces, only through gravity. Lastly, it is believed to be made up of different types of particles than regular matter, although the exact composition is still unknown.

3. What are some theories about the origin of dark matter?

Scientists have proposed several theories about the origin of dark matter, but there is still no definitive answer. Some theories suggest that dark matter is made up of exotic particles, such as weakly interacting massive particles (WIMPs) or axions. Other theories propose modifications to the laws of gravity, such as the theory of Modified Newtonian Dynamics (MOND), to explain the observed effects of dark matter.

4. Can dark matter be detected or observed?

Dark matter cannot be detected or observed directly, as it does not interact with electromagnetic radiation. However, its presence can be inferred through its gravitational effects on visible matter. Scientists use a variety of techniques, such as studying the rotation curves of galaxies or gravitational lensing, to indirectly observe the effects of dark matter.

5. How does the concept of "nothing" relate to dark matter?

The concept of "nothing" does not directly relate to dark matter, as dark matter is a type of matter that has mass and exerts gravitational effects. However, the fact that dark matter cannot be detected or observed brings up philosophical questions about the nature of "nothingness" and our understanding of the universe. Some scientists and philosophers have even proposed that dark matter may be a manifestation of the concept of "nothingness".
