why is space so cold?

Answer 1

The state of being cold is basically an absence of heat. The earth is warm because the earth holds heat and the things around us hold heat in them. But since space is a vacuum and there are essentially no particles in space there is nothing to hold heat.

Answer 3

Space is cold because anything in it will radiate all its heat away until it reaches equilibrium with the heat absorbed from the sun and the stars. That's why the moon is 100 celsius in the sun and -150 celsius in the dark.

On earth we are radiating about 100 watts all the time which we replace with metabolism. Plus we absorb heat from the air and radiation from the earth.

Answer 4

The radiation from various stars are the only source for energy.
Since radiation requires interaction with matter to jiggle the atoms and molecules and those jiggling are known as heat.

Since, space contains no considerable matter in the region of interest, one cannot feel heat.. However, these radiations can interact with our human body and can makes us feel heat .. like the temperature on solar cells while facing sun is hotter

Answer 5

The only reason our Earth is so warm is because we have an atmosphere that traps the heat. In space there is no possible way for the heat to get trapped.
If you want more info talk to me. This is just some basic easy stuff so you can understand it.

Answer 6

That depends on where exactly you are in space, but the majority of it is a cold vacuum that has little heat because there is little energy or particle movement to create heat.

Answer 7

Space is essentially a perfect vacuum. Heat is the result of atoms and molecules in vigorus motion. Since a sample of space has no atoms or molecules to speak of there is no heat in intergalactic space, however, if one was very near a star the effects of the stars radiation would boil your spacesuit and you into oblivion in a very short time. .

Answer 8

It is not cold in total. A person in his space suit on the moon will be +350 deg F. in the sun light. But on the shady side it will be -200 .

Answer 9

i bet on that pre.lives, you got it perfectly..
