In summary, the concept of dark matter remains a mystery in the field of astrophysics. While its existence has been theorized to explain discrepancies in observed gravitational effects, its exact location and composition remain unknown. Scientists continue to study and search for evidence of dark matter, hoping to further understand its role in the universe.

good question. some critics think people are doing bad experiments, and
then grasping at straws to explain the numbers.

i don't know what the answer is, but i think we need to focus more on
particle accelerators and scribling in notebooks.

Not sure if you're actually looking for an answer to this question, but here is one:

Dark matter does not seem to interact with EM at all, thus it is invisible. We can only detect it through its gravitational influence, meaning that so far, we can only detect it in very large quantities where we can observe its gravitational effects.

And ibably is all around us, we just don't know what to look for.

Dear R. H. Nigl,

Thank you for your question regarding the location of dark matter. As you mentioned, dark matter is thought to make up a large percentage of the universe, yet it is not easily observable. This is because dark matter does not interact with light, making it difficult to detect using traditional methods.

However, scientists have been able to indirectly detect the presence of dark matter through its gravitational effects on visible matter. For example, the rotation of galaxies suggests the presence of additional mass that cannot be accounted for by visible matter. This is one of the pieces of evidence that supports the existence of dark matter.

As for why it is not found all around us, it is important to remember that dark matter is not evenly distributed throughout the universe. It is thought to be concentrated in halos around galaxies and clusters of galaxies. This is why it is not as easily observable in our own solar system or on Earth.

While there is still much to learn about dark matter, scientists are actively studying and researching this phenomenon using a variety of methods, including particle accelerators and theoretical models. By continuing to investigate and gather evidence, we hope to gain a better understanding of the role dark matter plays in the universe.

Thank you for your interest in this fascinating topic.
 

Related to Re: 'Dark Matter'-where is it?

1. What is dark matter?

Dark matter is a type of matter that is believed to make up about 85% of the total mass of the universe. It is called "dark" because it does not interact with light and is therefore invisible to telescopes.

2. Why is it important to study dark matter?

Studying dark matter is important because it helps us understand the structure and evolution of the universe. It also plays a crucial role in the formation of galaxies and other large structures in the universe.

3. How do scientists search for dark matter?

Scientists use a variety of methods to search for dark matter, including studying the rotation of galaxies, observing the bending of light in gravitational lensing, and conducting experiments with particle accelerators.

4. Where is dark matter located?

Dark matter is believed to be located throughout the universe, but it is most concentrated in and around galaxies. It is thought to exist in a halo around galaxies, and also in between galaxies in large filaments.

5. Can dark matter be detected?

Dark matter cannot be detected directly because it does not interact with light. However, scientists can indirectly detect it through its gravitational effects on visible matter, such as the rotation of galaxies and the bending of light. Efforts are also being made to detect dark matter particles using advanced technologies.
