👉 In physics and astronomy, a pyrosphere is a hypothetical spherical structure that would form around a star if it were to become completely炽热。 It could be used as a way to study the effects of radiation on matter. The pyrosphere would have a thin, transparent outer layer that reflects all visible light, while its inner core would absorb and scatter all other forms of electromagnetic radiation. This would allow scientists to observe the properties of radiation in space and determine how it affects different substances.
