![]() ![]() ![]() A typical human body emits around 100 watts of infrared radiation (about the same amount of energy as an old-school incandescent light bulb). ![]() Without any air or water to surround your body, there’s no way for convection or conduction to transport heat and cool you off. At this point, achieving absolute zero is only theoretically possible. There are no parts of space, or anywhere in the universe, that can reach this temperature. This is the point at which even molecules don’t move. □ Zero Kelvin is a measure of the coldest possible temperature, absolute zero. Radiation is just that: emitting electromagnetic radiation. Conduction is the transfer of heat through physical contact, like when you accidentally touch a hot stove. Convection is the movement of a fluid, like warm air rising to higher altitudes. There are three ways to transfer heat from a warm body to its surroundings: convection, conduction, and radiation. However, the human body is rather inefficient at getting rid of heat, especially in the vacuum of space. Yes, space is generally cold, around 3 Kelvin, due to a bath of radiation soaking the universe known as the cosmic microwave background. If you want to survive this grisly scenario, you’re going to have to act quickly.įirst, It’s Going To Be Colder Than You Can Imagine.īut you’re not going to have to worry about freezing to death. You annoyed your crewmates enough that they did the unthinkable: they shoved you into the airlock and kicked you out of the space station. ![]()
