Description
Marc Mars and co-authors prove two results on trapped light tubes in de Sitter space in a 2024 paper. Such tubes trace the rims where light can just fail to escape. They are the math hearts of black hole edge studies.
First, in a broad class of space times, all such rim sheets are unstable. That blocks the standard path from sheets to full tubes. Second, a fresh family of round sheet stacks in a three sphere is scaled up. The scaling yields full tubes whose sheet area grows strictly with time. The pair of results frames how such tubes can be built at all.
