Difference between Dark energy and Dark matter

In summary, dark energy and dark matter are two distinct components of the universe that have been observed and studied by scientists. Dark energy is a force that causes the universe to expand at an accelerating rate, while dark matter is invisible matter that makes up a large portion of the universe's total mass. They are not directly related, but both play important roles in shaping the structure of the universe. While they cannot be directly detected, scientists use various methods such as observing galaxy movements and conducting experiments to study their effects on the universe.

They have absolutely nothing to do with each other.

Dark matter is a form of "non-standard" matter that only interacts via gravity with other matter (and itself)

Dark energy is the name given to the unknown force that causes the expansion of the universe to accelerate.

You really should learn how to use Google.
 

Related to Difference between Dark energy and Dark matter

1. What is the difference between dark energy and dark matter?

Dark energy and dark matter are two conceptually different components of the universe. Dark energy is a term used to describe the unknown force that is causing the universe to expand at an accelerating rate, while dark matter refers to the invisible matter that is believed to make up about 85% of the total mass of the universe.

2. How do we know that dark energy and dark matter exist?

Scientists have observed the effects of dark energy and dark matter on the behavior of galaxies and the expansion of the universe. These observations, along with mathematical models, provide strong evidence for the existence of these components.

3. How are dark energy and dark matter related?

Dark energy and dark matter are not directly related. Dark matter is believed to contribute to the gravitational pull that keeps galaxies together, while dark energy is responsible for the accelerated expansion of the universe. They both play important roles in shaping the structure of the universe, but in different ways.

4. Can dark energy and dark matter be detected?

Dark energy and dark matter are invisible and do not interact with light, making it difficult to directly detect them. However, scientists are continuously developing new methods and technologies to indirectly study and measure their effects on the universe.

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

Scientists use a variety of methods to study dark energy and dark matter, such as observing the movements of galaxies, measuring the cosmic microwave background radiation, and conducting experiments with particle accelerators. These studies help us to better understand the nature and properties of these mysterious components of the universe.
