Dark Matter & Dark Energy: Unfound Cosmological Science

In summary, dark matter is an invisible type of matter that is inferred through its gravitational effects on visible matter in the universe. It is different from regular matter in that it does not interact with light or electromagnetic forces, and is more abundant in the universe. On the other hand, dark energy is a mysterious force that is believed to be responsible for the accelerating expansion of the universe. It is not a type of matter, but a form of energy that permeates all of space and has a repulsive effect on matter. Scientists study both dark matter and dark energy through various methods, but their invisibility and lack of interaction with light make it extremely challenging. There are multiple theories about their nature, including undiscovered particles and modifications to our understanding of

That is what cosmology teaches us, dark matter, dark energy everything cosmological depends on unfound science?

Dark does not mean "unfound". In this context, it means that it doesn't emit a detectable amount of electromagnetic radiation. And yes, the majority of the energy density of the universe is "dark" in the mainstream model. It is certainly plausible that a modified theory of gravity could explain the apparent dark energy, eliminating the largest dark component, but no model has yet distinguished itself.
 

1. What is dark matter?

Dark matter is a type of matter that does not interact with light, making it invisible to telescopes and other instruments used to detect traditional matter. Its existence is inferred through its gravitational effects on visible matter in the universe.

2. How is dark matter different from regular matter?

Dark matter is different from regular matter in several ways. It does not emit or absorb light, it does not interact with electromagnetic forces, and it does not form atoms or molecules. It is also much more abundant in the universe, making up about 85% of the total matter in the universe.

3. What is dark energy?

Dark energy is a mysterious force that is believed to be responsible for the accelerating expansion of the universe. Unlike dark matter, it is not a type of matter, but rather a form of energy that permeates all of space and has a repulsive effect on matter.

4. How do scientists study dark matter and dark energy?

Scientists study dark matter and dark energy through a variety of methods, including observing the effects of their gravitational pull on visible matter, studying the large-scale structure of the universe, and using mathematical models and simulations. However, because both dark matter and dark energy are invisible and do not interact with light, studying them is extremely challenging.

5. What are some theories about the nature of dark matter and dark energy?

There are several theories about the nature of dark matter and dark energy, but they are still largely unknown. Some theories propose that dark matter is made up of undiscovered particles, while others suggest that our current understanding of gravity needs to be modified. Similarly, theories about dark energy range from the possibility of a cosmological constant to the existence of a new type of energy field. Further research and observations are needed to determine the true nature of these elusive phenomena.
