I am 9 years old. Can anyone tell me the answer on this one?
Hi quanum12345, that's a great question! Many scientists are working very hard to figure the answer out. What we know is that there is at least about 5 times as much dark-matter mass, as 'regular' (called, "baryonic") mass. Also, for a number of reasons, we expect that the mass of each dark-matter particle is much-much more massive than any of the particles which make up normal matter (i.e. protons, neutrons, especially electrons).quantum12345 said:I am 9 years old.

Dark matter is a type of matter that makes up about 27% of the universe. It does not interact with light, making it invisible to telescopes and other instruments. Its presence is inferred through its gravitational effects on visible matter.
Scientists use a variety of methods to estimate the mass of dark matter. These include measuring the rotation curves of galaxies, gravitational lensing, and studying the large-scale structure of the universe.
One of the main challenges in determining the mass of dark matter is that it does not interact with light, making it difficult to directly observe or measure. Scientists must rely on indirect methods to estimate its mass.
The current estimated mass of dark matter is about 5.6 times the mass of visible matter in the universe. This means that for every visible particle, there are approximately 5.6 dark matter particles.
No, dark matter cannot be detected in a laboratory setting because it does not interact with light or other forms of electromagnetic radiation. However, scientists are working on developing new technologies and experiments to try and directly detect dark matter.
