SUMMARY

The discussion centers on the elusive nature of dark matter, which constitutes a significant portion of the universe yet remains undetectable through conventional means. Participants highlight that dark matter does not interact with electromagnetic forces, rendering it invisible to current observational techniques. Its presence is inferred solely through gravitational effects, suggesting that dark matter may indeed be ubiquitous, but its detection requires advanced methodologies such as particle accelerators and theoretical exploration.

PREREQUISITES
  • Understanding of dark matter and its role in cosmology
  • Familiarity with electromagnetic interactions and gravitational effects
  • Knowledge of particle physics and the function of particle accelerators
  • Basic principles of observational astronomy
NEXT STEPS
  • Research the methodologies used in particle accelerators for dark matter detection
  • Explore gravitational lensing as a technique for observing dark matter
  • Study the implications of dark matter on galaxy formation and structure
  • Investigate current theoretical models of dark matter, including WIMPs and axions
USEFUL FOR

Astronomers, physicists, and students of cosmology interested in the properties and detection methods of dark matter.

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.
