Gosh, you gotta love those scientists. They probably had a quiet chuckle amongst themselves when they decided to create the acronym of WIMP when they came up with a possible explanation to support the theory of dark matter. These theoretical particles are huge and can’t be seen by the naked eye (or telescope for that matter).
The only way they can be ‘seen’ (they don’t absorb or emit light) is by viewing their gravitational impact on other visible objects.
