I recently played Oxygen not included. And it learned me space is not that cold, it can also be warm. If you have electronics in a vacuum they have nowhere to pas on their energy. So they get really really hot. And with with the radiation thing, it means that if you are able to see it, it is radiating and loosing energy/temperature

[@drvishnu44]

Next topic to watch: What is radiation and why do we lose heat through it? Lose it to what?

[@aniketmeshram6598]

Maybe cause of laws of thermodynamics, we do lose heat? Temperature of system and surrounding tends to remain same, Thats law, I am not sure,

[@aniketmeshram6598]

And everyone knows radiation is nothing but a wavelength of different colours of Light, Maybe? Its just on the basis of science i ve learned in higher school

[@bs_blog]

Surrounding .........be it anything! It sort of like a room with one small light/heat source. So it is hot at that point. But when it starts to spread heat to the surroundings and the room, the entire room is not even at half the temperature of the of that heat ball. I hope this explains.

[@jenromeave4793]

I recommend learning blackbody radiation, a topic in quantum mechanics; it explores the idea underlying the mechanism of radiation further. Studying the concept alone without any reportoire of advanced physics or mathematics is fine.

[@desiseattle7395]

Radiation is scientific jingo to explain emission of, absorption of light energy in all wavelengths. Light, the the dual property of matter and wave, which photons, travels in different wavelength and frequency. Once light or photon is generated from within an atom, it just cannot stay at one place, it travels or transfers. Photon carries energy. You loose energy, because your body is at 37 deg C as wells as due to entropy when your surrounding is less than your body temperature. If your surrounding is higher than your body temperature, you will gain heat and you may get incinerated as well. Also your body also makes own head in the metabolic biochemical reaction process.

why is it so difficult to vent heat from the space station?

[@MadMax-xc4lr]

Because space is vaccum and heat transfer is slow

[@Oklahoma-Dreaming]

It’s been since high school I took chemistry although I took the Physics series in college. I believe that, since space is nearly a vacuum - a “true” vacuum probably doesn’t exist - there are no atoms, like what exists in our atmosphere. And it’s the excitation of atoms from radiation or radiant heat that causes them to move. This causes friction snd therefore heat as potential energy is released. (I’ll have to watch the video now to see how far off I am.)

[@peter4210]

You would not freeze immediately, nor would you die immediately, you can survive for as long as your body can with out oxygen which is not long enough to freeze. If you had a oxygen supply, you could heat to death or freeze to death depending on what side of the earth you are on. Your body would not be able to keep you warm or cold enough on it's own and you would die then but it would take a bit more time after your death for your body to reach 0C Don't believe what you see in movies. The most accurate thing i saw were people running on mars covered in duct tape to protect their body from vacuum to a place with oxygen pressure in under a minute which is more then survivable. For the why you get cold to death, like the video tried to explain, your body losses heat in the form of a radiation we can detect with special cameras called infrared cameras. If you are far enough from anything that can warm you up, you will end up losing more heat then your body can make and you will die from hypothermia

Cold is the absence of warmth. Thus no warmth = cold. Because warmth is always related to energy. A star creates energy, which means it heats up an spreads the heat (radiation). But due to the empty space and the distances, there is nearly nothing that can be heaten up.

[@totoysikwat8922]

I cannot imagine space being a vacuum. Imagine if everything in the universe return to its most fundamental form, the fundamental materials or particles should then exert pressure on each other. Otherwise they will not become dense enough to cause a rise of temperature for big bang to take place. We only say that space is a vacuum because we got use to measuring pressure using the Earth's atmosphere. How do we have pressure at macroscopic and molecular level then it suddenly disappear at particle level? Does it mean that the particles does not exert pressure on each other? It is counter-intuitive to say that the quantum space between particle is empty but the spaces of the molecule is not empty even though molecules are made up of particles. This is something that should be look upon.

Where does the heat off an object radiate to if there is nothing in space ….

[@Oklahoma-Dreaming]

Technically I believe “cold” doesn’t exist. It’s simply the absence of heat, but to a degree. If you could hit absolute zero (AZ) - perhaps in the Kelvin scale? - there would be no heat at all. But I think it’s only theoretical because i believe at AZ electrons don’t even spin. I would guess that no place in the Universe is truly AZ. (Heat I think decays as a function of k / r ^ 2 so while it goes to zero fairly quickly as an inverse parabolic it never really reaches zero.)

so it is cold. definition of Cold is just the lack of heat. you can say "Depending on where you are in space give or take it's hot OR cold, but however space itself has a lack of heat because it's a vacuum of nothing which.... makes it cold. it's a vacuum with a lack of heat meaning it's not hot/warm so it is cold. if you go into space your skin mind and body would register it as Coldness as there would be no heat source. i think the video is saying to Space' standards it's a big space vacuum of nothingness it's impossible for "nothing" to have a temperature, when in actuality the feeling of "cold" is not a temperature just lack of heat. given space has 1 source of a way of heat (the sun/stars-Radiation) it can't heat space up entirely due to it being an infinite vacuum, thus making space lose heat the same time as its gaining heat. my main question is "well would i sweat or would i shiver?" it basically depends on where you are in space but in actuality you would shiver. thus the answer being cold. have you ever put your hands under really hot water in the faucet and it felt so hot that your mind registered it as cold? you'd either be so hot you'd shiver or so cold you'd shiver.

[@bbj54485]

The way speed and time works in space is complicated. A light year is basically how much time it will take for light to get to it's destination. So it will take 4 years for light to arrive at its destination. If you start at earth in a car going 60 mph your going absolutely no where. In space, 60 mph your moving way slower than a snail. If you take a space ship and you are going 56,000 km/h your still not going anywhere. 56,000 km/h is about mach 47 and the speed of light is about a billion times more than that. The speed of light is around mach 4600(yea I know thats a thing). If we can travel 20 percent the speed of light we have enough speed to to travel to other stars but it will take far longer than 4 years. For us to arrive in a different star as fast as possible(4 years) we have to be going at least 95-100 percent the speed of light.
