Temperature in Space

Temperature in Space

Space, as we all know, consists of a vacuum. Or just distance without any matter, if you happen to be unfamiliar with the term "vacuum".

And according to wikipedia, space holds a temperature of roughly -270C (-454F). So my question is: How can vacuum hold a temperature?

Wiki Reference

All of the observable universe is filled with large numbers of photons, the so-called cosmic background radiation, and quite likely a correspondingly large number of neutrinos. The current temperature of this radiation is about 3 K, or −270 °C (−454 °F).

Correct me if I'm wrong. Above quote says that vacuum can not hold a temperature. And the temperature in outer space is hold by photons and neutrons (which have a mass)?

And if that is true, it brings me to another question!
The cosmic background radiation, is it present exactly everywhere?

If we would find a spot in the universe without this radiation, (which means no mass since all mass is more or less radioactive) would that spot have no temperature? And by that I don't mean the absolute lowest, or highest temperature, I mean a total abstinence of temperature

Re: Temperature in Space

Heat is caused by particles colliding. Remove the particles you remove the heat

Re: Temperature in Space

Well you can't have an absense of temperature, since that is just a way of measuring heat. You can have an absense of heat and we call this absolute zero (in the Kelvin scale, if I'm not mistaken), which is where there are no atoms present to be heated.

But space isn't really a vacuum anyways. For every cubic metre of space there is at least one hydrogen atom. So really space is just one big hydrogen cloud :lol:

Hehe I'm a nerd....

Re: Temperature in Space

I knewe there were some particles in space but didn't know the ratio this of course doesn't factor in the quantum elements
