The discussion centers around the limitations of posting metaphysical ideas and personal theories on a science forum. The forum's mission is to focus on established scientific knowledge as recognized by the professional community, leaving little room for speculative or non-mainstream topics. Users are encouraged to engage with theories that are grounded in peer-reviewed literature rather than personal interpretations. There is a clear distinction made between mainstream science and topics that are considered cutting-edge or speculative, which are not welcome unless published in reputable journals. Ultimately, the forum aims to facilitate learning about standard physics while discouraging personal speculation.
