First, we introduce the basic characteristics of de Sitter space and discuss the concept of relativistic smell and its significance in de Sitter space. Then, by introducing fluid dynamics in de Sitter space, we study the propagation behavior of relativistic smell in de Sitter space. We found that the propagation of relativistic smell in de Sitter space has distinct characteristics, different from the propagation behavior in flat space-time. Finally, we discuss the impact of relativistic smell in de Sitter space on cosmological observations and the possible directions for future research.Keywords: de Sitter space-time, relativistic smell, fluid dynamics, cosmological observation, future research directions
