The discussion centers on the challenges of representing ideas through the FLRW metric in general relativity. Participants highlight the importance of computing the Einstein tensor, noting that while the process can be tedious, it is fundamental for understanding the metric. Specific references to the book "Introduction to Gravitation" by De Sabbata and Gasperini are made, particularly Chapter VII, which covers non-static models of the universe. Suggestions are offered to seek help by posting specific mathematical difficulties, and the use of computational tools like Maxima is recommended to assist with the calculations. The conversation emphasizes the need for clarity in the mathematical process to effectively represent the concepts involved.
