How do I discuss cross-topic themes in usenet?

Question by 5minGuru: How do I discuss cross-topic themes in usenet?
If I have a topic that belongs to or touches two or more separate groups or subjects in usenet, how do I post this then?

For example: I want to know what is the relation between information (information theory) and energy (physics). Or the biological view of religion…and so on.

What you are describing is called “cross-posting” and the way to do it depends on what news-reader you use though it might be as simple as entering a comma-separated list of newsgroups or adding additional “To:/Newsgroup:” headers.

Before cross-posting, please ensure that the groups you are targeting allow cross-posting and have compatible content rules or customs.
