How close can a human get to the Sun before burning up?
Could you please elaborate on the factors that determine how close a human could potentially approach the Sun without sustaining severe damage or burning up? Are there any known technologies or materials that could potentially shield a person from the extreme heat and radiation of the Sun's surface? Additionally, have there been any successful missions or experiments that have tested the limits of human proximity to the Sun, and what were the results of these endeavors?
