The discussion centers on the hypothesis that dark matter originates from another universe and interacts with our universe solely through gravity. Participants emphasize the importance of adhering to mainstream scientific theories, rejecting personal speculation. Several hypotheses regarding dark matter's interaction are mentioned, including "exotic" matter, unseen normal matter, and modifications to gravity, with a recommendation to consult a Wikipedia article for further details.
PREREQUISITESAstronomers, physicists, and students interested in cosmology and the fundamental forces of nature will benefit from this discussion.
StavrosPanagiotidis said:I think that dark matter is matter from an other universe that we can only interact with through gravity.
StavrosPanagiotidis said:Does anyone have a hypothesis for why does the matter interact with us only with gravity and not with any other of the fundamental forces like electromagnetism etc.
Thanks, I will try to stick to mainstream science.Drakkith said:Personal ideas, speculation, and theories are not allowed here at PF. We like stick to mainstream science.
Yes, there are many hypotheses. Check out this wikipedia article if you'd like to know what those are. Possibilities include "exotic" matter, unseen normal matter, and modifications to gravity.
