What is dark matter? Show more Show less
Back to question

Dark matter makes up at least 27% of the universe. Everything on earth only adds up to less than 5% of the universe. Dark matter has been a mystery for a long time and continues to be in so many aspects. What is dark matter, and what do we know about it?

Dark matter is made of non-Baryonic matter Show more Show less

Dark matter is not baryonic at all. It is made of more exotic particles like axions or Weakly Interactive Massive Particles (WHIMPs).

Dark matter is made of WIMPs

Weakly Interacting Massive Particles (WIMPS) have been attractive candidates for what may make up dark matter. Scientists place hope on WIMPs as particles that would connect the large cosmic scale of physics to the standard models of physics.

The Argument

WIMPs initially originated as an outcome of string theory. Scientists then started looking at them as dark matter candidates. WIMPs are attractive candidates because they show up in two theories in physics and attempt to solve more than one question.[1] Scientists study the hypothetical WIMPs by attempting to sense them in underground detectors as they pass through the earth and by trying to creat them in accelerators.[2] WIMPs are very massive particles that scientists proposed as a component of dark matter. They interact weakly with normal matter. Scientists predict that they go back to the beginning of the universe 13.7 billion years ago, but scientists did not discover enough of them account for dark matter. WIMPs include heavy neutrinos which have been strong candidates for dark matter. [3]

Counter arguments

WIMPs interact weakly with normal matter and are very difficult to detect. Most of them pass through earth without getting stuck or without colliding with normal matter like materials on earth. If particles do not collide with normal matter like with a detector they cannot be sensed. WIMPs need highly sensitive equipment and research has not reached the ability to detect them. The large underground xenon detector (LUX) in South Dakota is the major instrument for studying WIMPs and it hasn't detected a WIMP yet since 2014. Scientists cannot be exactly sure of the existence of WIMPs if they cannot detect them. [3][4]
