The video explains why space is perceived as cold despite the presence of numerous hot stars. It highlights the role of the sun in heating Earth and the importance of Earth's atmosphere in retaining heat. The video clarifies that space itself is not cold or hot, as it is a vacuum with no temperature. It discusses heat transfer methods—conduction, convection, and radiation—and their relevance in space. The vast distances between stars and the vacuum nature of space contribute to the coldness experienced by objects far from heat sources.
