The discussion revolves around the policy of Physics Forums regarding Lorentz Ether Theory (LET) and the Block Universe concept. Participants explore the implications of philosophical interpretations of these theories, the level of debate among physicists, and the relevance of such interpretations in the context of current scientific understanding.
Participants express a range of opinions, with no clear consensus on the necessity or relevance of philosophical interpretations in the context of LET and the Block Universe. The discussion reflects competing views on the importance of these interpretations and the level of debate surrounding them.
Some discussions touch on the limitations of current theories and the potential for future developments, but these points remain speculative and are not universally accepted among participants.
Fair enough, but both present the same moderation challenge so are covered by the same policy - and this thread is about the policy.OJ Bernander said:The OP comes across as setting up BU as an alternative to LET. I always thought of BU as an alternative to Presentism (a sliding "now"). LET, meanwhile posits the existence of a medium, a different issue altogether, as it can exist (or not) in but BU and Presentism.
