The sun gives us light because of nuclear fusion-two atoms of Hydrogen are combining in huge quantities to form one atom of Helium. The mass of two atoms of Hydrogen are slightly more than one atom of Helium, which is mono atomic.The difference in this mass is converted to energy in the form of Heat and Light, rays of which don't need a medium to travel.

The answer to your question would depend on (1) whether "empty" means a "perfect vacuum" or filled with air? (2) how is this 1 joule of energy initially distributed inside this box? (3) how large is this box? (4) how much time is allowed to elapse before the termperature is determined? (5) can energy leak out or into the box? (6) is the box under the influence of a gravitational field?\n\nThe temperature of an object is proportional to the average kinetic energy of the molecules in it. In a pure vacuum, there are no molecules. There is nothing to measure the kinetic energy of, and temperature is undefined. If a thermometer were placed in a vacuum, the reading would be a measurement of the internal temperature of the thermometer, not of the vacuum which surrounds it. So having 1 joule of energy inside a box containing pure vacuum would have NO temperature. And if it contained air, then we would need to know the initial temperature, pressure of the air inside the box and also the volume of the box. Then we can approximate the air as an ideal gas and use the following equation to compute the temperature:\n\nPV=nRT\n\nwhere T is the temperature, n is the number of moles of gas and R is the gas constant. Since we know the initial temperture and pressure, and the volume of the box. Then\n\nP(i)V(i)/T(i) = P(f)V(f)/T(f)\n\nT(f) = T(i) [P(f)/P(i)]\n\nSince pressure is dfined as P = F/A (force per unit area) and\n\nE = Fd (force times distance), then\n\nP = E/Ad, where Ad = V volume of the box (here we are assuming that the 1 joule of energy is uniformly distributed inside the box and the volume of the box does not change)\n\nHence, T(f) = T(i) [E/P(i)V(i)]

Actually, There is no such thing as a true vacuum...Period!\n(exerpt from a previous answer)\nContrary to popular belief, empty space is not empty, and it is certainly not a vacuum. In fact, a true vacuum has never been created, anywhere, where the atomic count is zero.\nresearch it, its true.\n"Empty" space actually contains an average of 1 hydrogen atom for every 32 cubic centimeters of space, this data is per NASA.\n\nIn our own Milky Way, space is more dense with 1 hydrogen atom for every 1 cubic centimeter.\n\nOne day the misinformation of space as a vacuum will finally die out.\n\n\nspread the knowledge

actually, there may be something in the nothingness of a vacuum....\n\nwell,, sound (waves) needs a medium for it to travel...\nmedium like solids and fluids...\nsound (waves) cannot travel in a vacuum..\nthere's nothing in a vacuum...\nthat's why there's no sound...\nno pressure is created by the sound waves...\nthst's why there's no sound...

There's no oxygen in space but we all breathe. The sun has enough gravity to keep the oxygen inside it just like Earth but even more so. However this oxygen isn't for burning like we would burn wood. It is part of the cycle of nuclear reactions going on in the sun. The gravity of the sun is large enough to keep the mass of gas concentrated enough to be able to sustain such nuclear reactions.

Nope.  A vacuum (not "vacume") means that there's not any air to begin with, and because a fan cannot produce air, only move it around, no air will be given off.

All the techno babble apart - space has no end.\n\nThere is a distinction between space and universe. When talking about space in common man's language we talk about what is outside earth's atmosphere. That space has NO END. It is infinite in all directions and contains the moon, the planets, the sun, the starts, the galaxies, our universe formed after the big bang and beyond (probably several more universes formed of separate big bangs that are dying or forming like stars do).\n\nNow about a sphere's surface having no end but an area, well this has nothing to do with end of either universe or space or a sphere.. when viewed from the center of a sphere, a line drawn in any direction will intersect the surface of the sphere and therefore the entire surface of the sphere is an end. Space on the other hand has no end, it extends out to infinity.\n\nA simple way of understanding this is imagine you are in a room in a building. The room ends with the walls, but beyond the walls there is something - maybe more rooms. The rooms end with he building's walls but even beyond that wall there are more buildings. There is no end, if you imagine an end and if you could stand at the end there would still be something beyond that end more empty space maybe. No matter how large a number you imagine there is always something bigger. Numbers just like space go till infinity.

no....\n\nit wont need fuel..... it is moving in the space only through the gravitional force...

Space is technically a vacuum, hence void of any matter, invisible, see-through, like a very clean window! That's also why they placed the Hubble Telescope in orbit, out of the atmosphere.  The atmosphere seriously effects a telescope's ability to 'see' far into the universe.  It's essentially like looking through a dirty glass, because of all the particulate.\n\nSo,\nIn space no physical matter, no perception of light.  There is no air and/or physical matter for the light to bounce off of and around etc..\nIn other words, the reflections of light from objects creates the effect we perceive as light, or being lit-up.  \n\nAny solid will also be illuminated by the sun, in space. Proof of that is the moon, or any other planets visible by eye or telescope.  \n\nOur atmosphere (air is matter too) gives the appearance of being "lit" up, and all the solids on earth reflect that light, causing the effect of being "lit up"..\n\nTry this.  Go into a completely dark room, and turn on a good straight beam flashlight.  Can you see the particulate in the air?  The little lighted particles?  If they weren't there, all you would see is the white dot on the wall, that the light creates.  The reason you can put your hand next to the beam and still see it is from the reflection on the wall, AND the particle matter in the air, which causes light to stray onto your hand.  In this case it's more the reflection, but both aid in you seeing your hand..\n\nNow, take that HUGE flashlight in the sky *sun*, and apply that to what you have asked!

About 1 atom for every 32 cubic centimeters\nActually, There is no such thing as a true vacuum.\nA true vacuum has never been created, anywhere, where the atomic count is zero.\nThere is always atomic content left to fill the "vacuous" space. No one has ever been able to creat a true vacuum.\n(exerpt from a previous answer)\nContrary to popular belief, empty space is not empty, and it is certainly not a vacuum. \nresearch it, its true.\n"Empty" space actually contains an average of 1 hydrogen atom for every 32 cubic centimeters of space, this data is per NASA.\n\nIn our own Milky Way, space is more dense with 1 hydrogen atom for every 1 cubic centimeter.\n\nOne day the misinformation of space, or anything else, as a vacuum will finally die out.\n\nIf you are referring to a vacuum cleaner.... then dirt.\n\nspread the knowledge

Space does not come in particles.\n\nThere is no aether.\n\nQuantrons do not exist.\n\nBut apart from that I'd say you're probably almost right.

Nothing will happen man. It's vacuum out there, no nitrogen CO2 and so on.. so no decomposition can take place.

OK... let's get graphic.\nFirst off..... you'd die! No way around that!\nWhat would kill you first is the question.\nSpace is incredibly cold, so instant exposure to space would freeze almost all liquid in your body solid.\nSpace is also a HUGE vaccum, so all the air would be sucked out of you either while you're freezing solid, of during your freezing process.... either way, you'd suffocate if you didn't freeze by some miracle.\nSpace has absolutely no compromising pressure like the inside of our atmospere. Our bodies are used to a certain atmosperic pressure. Without it (I.E in space) if you didn't freeze or suffocate, eventually the lack of pressure would collapse our fragile bodies.\nThe possibilities for death are indeed endless.

To quote from wikipedia:\n"Outer space, also simply called space, refers to the relatively empty regions of the universe outside the atmospheres of celestial bodies. Outer space is used to distinguish it from airspace (and terrestrial locations). \n...\nThere is no clear boundary between the Earth's atmosphere and space as the density of the atmosphere gradually decreases as the altitude increases. Nevertheless, the Federation Aeronautique Internationale has established the Kármán line at an altitude of 100 km (62 miles) as a working definition for the boundary between atmosphere and space."

Space doesn't exist. There are things IN space. Matter makes up the stars and planets and gasses and eveything you see. Everything you DON'T see, I.E. the large black void, is nothing. There is no matter or antimatter or anything there. It's just....emtpy. Therefore, it doesn't exist. Only the things in it exist.

Surprise, They do not fall at the same rate- Theoretically, if there were such a thing as a true vacuum, then things would fall at the same rate. However, a true vacuum with zero atomic content has never been created, anywhere...period. This is one of the most misleading assumptions in science today.\nPlease reasearch it and you will find that there is always some atomic content that remains regardless of our best efforts to eliminate it. \n(Exerpt from another answer)\n"Empty" space actually contains an average of 1 hydrogen atom for every 32 cubic centimeters of space, this data is per NASA.\n\nIn our own Milky Way, space is more dense with 1 hydrogen atom for every 1 cubic centimeter.\n\nYes in a vacuum, things would fall at the same rate, but since there is no vacuum, they don't.\n\nshed the light
