Random Science Questions

[abudabit]

Q1) Why do people say space is really cold if it is a vacuum? Isn't heat (or the lack there-of) the result of vibration of molecules?

Q2) You have a jar that weighs exactly 100 mg. Air pressure is normal. You remove the lid, and place an insect in there which weighs 10 mg. You close the lid. The insect begins to fly, and hovers in the middle fo the jar. How much does the jar weight?



I don't know the answers to either of these. Answer them, or ask any science questions you don't know the answer to.

Q2 is an easy answer, it weighs 110mg. Although in practice, I don't think it would be easy to find any bug that will fit into a jar that weighs a tenth of a gram. But I know what you mean, and the scale isn't important. The jar, the air inside, and the bug are all one unit that weighs as much as the total of their individual parts.

Q1 I have to think about.

That was an interesting question.. These pretty much explain it. If there were no particles at all, there would be no temperature at all. But there always are particles, just not many. Any single one might be very hot, but the average is 2.7K.

:smarty:

can we take completely unfounded guesses?

1. heat is also a byproduct of solar energy. because theres no atmosphere in space to absorb and store the heat like our atmosphere(greenhouse gases and water) space is probably cold. also considering the extreme difference in size between the universe and planet earth, the same amount of solar energy spread through out the different areas can also explain the temperature difference

2. the jar should still weigh the same under normal circumstances, provided the bee has the same density as the air it displaces, otherwise it should weigh more in ideal conditions.. i.e think of how a jar would weigh more if instead of air, it was filled with powder suspended in the air

[Bagel Lord]

Q3) Does ice melt in warm liquids because the cold energy of the ice passes onto the beverage, thus cooling it, or because the warm energy of the beverage passes onto the ice cube, thus warming it?

This has been bothering me for years.

:smarty:
1st question i'm not sure, but i'm guessing it's cause there is nothing to hold the heat in, around the closer planets to the sun it's extremely hot, but if there is no atmosphere, there is no way for any heat to stay instead of keep traveling.
2nd question is while the bug is in the jar, and flying his wings are exerting a push on the air down equal to his weight for him to be able to fly. I think thats correct, we learned about in science but i also failed most of my science classes.

[abudabit]

Q3) Does ice melt in warm liquids because the cold energy of the ice passes onto the beverage, thus cooling it, or because the warm energy of the beverage passes onto the ice cube, thus warming it?

The second. There is no such thing as "cold energy". Cold is a lack of energy. The energy from the warm liquid transfers to the ice, thus warming the ice. Since energy is leaving the warm liquid for the ice, there becomes less energy in the liquid.

[DrumCorpsAlum]

About the bug in a jar question, the bug has to exert lift, which would be equal to it's weight, therefore pushing down on the bottom the same weight. Mythbusters did this with pigeons. Same this with the force on the wing of an airplane.

[Hudson]

q1) actually, If I recall correctly, direct view of the sun raises the tempurature of an astonaut on a space walk close to 250 degrees, the space suit protects him, much as the lack of solar radiation chills him down by 200 degrees ( I got it off of The Right Stuff or Armageddon..I forget.).

Q1. Heat is because the vibration of atom's.
Because space has nothing nada it can't have any heat. Hence Abouslute zero. Even though water freezes at 32 degrees F. That still is a unit of heat.

Q4 ] If you built a box and lined it with perfect mirrors and sucked all the are out until it was a perfect vacuum. You then shined a flashlight in the box. In 10,000 year someone open the box would they see the light from the flash light?

[Cunt Smasher]

Q1-I think space is very close to 0 degrees Kelvin,which is the absolute absence of temperature.
Q2-Doesn't the jar itself weigh the same no matter what? -like the old gag "what's heavier,a ton of lead or a ton of feathers?"

[CrazyMrPoopSex]

Q1) Isn't heat (or the lack there-of) the result of vibration of molecules?
answered your own question, without the atmoshere to hold heat it is cold.
absence of heat = cold

There would be light in the box, but a human eye would not be able to see it. The maximum duration of the light would be how long it takes light to travel the distance of the interior of the box. Wouldn't even be 1/10000th of a second.

[THE FEZ MAN]

also isn't it that space is "cold" its just lacking matter to heat? since when your inspace when something is exposed to the direct radiation of the sun it gets incredible hot yet on the other side its dispersing its heat, hence cold with the exception of what is coming through the part because of conductivity of the part? hence why the shuttle is covered with tiles? and most shit in space is white or reflective?

Wonder if Jimmy could go beat on Dr. Kaku's door and ask him this. He was on the history channel show that made me wonder about this.

Picture the universe as a balloon. It is getting blown up larger and larger as time goes on. The rate it expands is immaterial, I assume it's at a constant rate(time). It expands in all directions simultaneously. If I were blowing this balloon up on earth, the edges would be expanding into the air (matter) around it, displacing (space) it.

The universe is ever expanding in all directions. Since the there is only one universe, and that universe encompasses all matter, space, and time, what are the edges of this expanding universe expanding into? A void, empty of space, matter, and time? What would this void be called?


That's as well as I can explain my question.

Job Number 1 for the tiles on the Space Shuttle is the reflecting heat from re-entry, not heat from the sun. Protection from the sun is a secondary (and imnsho - distantly so) purpose of the the tiles.

For the first part of your question: All the galaxies, dust, energy, etc. are expanding out there. Imagine that each galaxy is an atom, and the universe is an orb made of those atoms. That orb is expanding in size, with the distance between each atom expanding.

For the second.... well we just don't have that answer I think.

Also, there is an additional theoretical constituent of the universe. Dark matter. According to many calculations, 70% of the mass in the universe is unaccounted for. There is something that can't be touched or detected that is generating gravity. But we don't feel that gravity because it exists evenly through out the universe. And that dark matter doesn't exist outside the boundaries of the universe, so the gravity from it helps hold the universe together.

I have no idea how accurate that last paragraph is, it's just my understanding of that very complex quandary. Also it's still all speculative theory anyways.

[Bluestreak]

Because space has nothing nada it can't have any heat. Hence Abouslute zero. Even though water freezes at 32 degrees F. That still is a unit of heat.

1. Absolute zero K is damn near impossible. Check your facts, and I don't mean Wiki.
1a. Heat transfer (say from an "interstellar ship" to the surrounding space) is a different story because there is nothing that acts as a medium for the energy.

Ok, time to kick this up a notch:

Q6) The theory of special relativity

Now, if the speed of light is the limit a particle can reach.... and if the theory of special relativity says that there is no universal reference point.... let's say that a space ship is traveling at 1/10th the speed of light towards a probe. Electromagnetic radiation is emited from the space ship towards the probe so that the probe will be able to detect it.

Does the probe detect the electromagnetic radiation as traveling as 1.1 times the speed of light, or does it detect it as 1 times the speed of light?

It'll detect it at whatever speed the signal is sent. There will be a shift in the signal based upon the speed of the original object. You'll see "blue shift"

Oh an Q5. The entirety of the universe is all matter and energy. If there is something beyond the known universe then it is still the universe. Which creates a shitload of questions.

[BCH]

If I seperate quantum entangled particles by some great distance say earth - mars and then alter some attribute of the earth-bound particle say spin or flavor in a predictable way, in a sort of morse code, doesn't my information travel at faster than the speed of light, and doesn't that violate special relativity?

:martianvirus:



Please elaborate, why does it possibly travel faster than light?

[BCH]

Because the distant particle's spin or flavor or whichever attribute is entangled would change to match it's partners' ostensibly in zero time thereby transmitting information, say morse code in less than the obligitory 30 or 40 minutes predicted by the speed of light.

My physics teacher in high school was awesome, it was a great class and I opted to take it. I just couldn't grasp the idea of there being other dimensions.
Does anyone think we'll figure a way to go into another dimension?

Ahh, I get what you mean.

Well this is lame and cheesy and an incomplete answer but I looked it up on Wikipedia (yeah, I know). This is one of the entries on things which can theoretically travel faster than light:

In quantum mechanics, certain quantum effects may be transmitted at speeds greater than c (indeed, action at a distance has long been perceived by some as a problem with quantum mechanics: see EPR paradox, interpretations of quantum mechanics). For example, the quantum states of two particles can be entangled, so the state of one particle fixes the state of the other particle (say, one must have spin +½ and the other must have spin −½). Until the particles are observed, they exist in a superposition of two quantum states, (+½, −½) and (−½, +½). If the particles are separated and one of them is observed to determine its quantum state then the quantum state of the second particle is determined automatically. If, as in some interpretations of quantum mechanics, one presumes that the information about the quantum state is local to one particle, then one must conclude that second particle takes up its quantum state instantaneously, as soon as the first observation is carried out. However, it is impossible to control which quantum state the first particle will take on when it is observed, so no information can be transmitted in this manner. The laws of physics also appear to prevent information from being transferred through more clever ways and this has led to the formulation of rules such as the no-cloning theorem and the no-communication theorem.

I think this and other contradictions is why Einstein was so against Quantum Mechanics. He called it an incomplete theory or something along those lines.

[abudabit]

My physics teacher in high school was awesome, it was a great class and I opted to take it. I just couldn't grasp the idea of there being other dimensions.
Does anyone think we'll figure a way to go into another dimension?

I think when people talk about dimensions they are using outdated sci-fi understandings of the subject.

If the 1st dimension is linear, the 2nd dimension is 'flat', the 3rd dimension is what we normally think of as 3d (true 3d, not computer graphics), and the 4th dimension is time, what is the 5th?

We have control over our bodies in the first 3 dimensions, but we are actually living in a 4 dimensional existance and to some extent can alter our 4th dimensional course. By traveling very quickly we can alter the way we travel in the 4th. Just because we can't time travel in the sci-fi sense doesn't mean we aren't navigating the 4th dimension. Just as physics constraints mean you can't jump below the earth on a whim, there are physics constraints that say you can't jump in time.

So the question becomes, will we have more control over the 4th just as we have decent control of the 3rd? I think with each additional dimension the ability to navigate it gains additional restraints.

And the 5th? Does it exist? I think not, I used to, but now it just seems like something the imagination has created to allow for diverse plots to fiction. The 5th seems like wishful thinking.

On the bug in a jar question:

Once the bug is in the jar the mass of the closed jar will never change.

The weight, however, will fluctuate as the bug accelerates upward due to the down-force created by his wings, or the impact of him landing. You have to seperate the concepts of weight (force) and mass (material)

Also, assuming the bug could exist in an oxygen free environment, if you were to make the jar a perfect vacuum, the bug could not fly.

Heat in space:

This would depend solely on your exposure to the radiation of a star. Yes, the lack of atmosphere would prevent any actual heat energy transfer through atmospheric conditions, so int he absence of radiated heat from a plasma (nuclear) source there would seem to be freezing conditions, as the molecules of your skin/thermometer would have no molecular vibrations to transfer their kinetic energy, and would eventually succumb to the stillness surrounding them much like a ball would stop rolling on a flat surface. (There's other things to consider, but this is the simplest explanation)

In an environment where there's radiation exposure, however, the photons or other sub-atomic particles would be hitting the molecules of you/your ship/your thermometer probe, thus transferring their kinetic energy to the molecules, creating heat energy (and likely subsequent nuclear-chain reactions, which would perpetuate this "heat" energy)

Think of space like an empty pool table, and your thermometer like a rack of balls. The still rack would be considered "cold", ie no kinetic energy at the molecular level. Once you break, however, the cue ball acts as a photon particle would (Gamma radiation) and causes "heat" energy by causing all 15 molecules to "vibrate" as they're scattered all over the table. You would also have negligible affects from what small amounts of molecules that do exist in space (ie, space dust, etc) much like you would if there were little lint balls on the felt of the table.

Wonder if the box will melt if you kept it shining on it.

Actually though, one way glass does let light pass out the other way. That's why you're able to see the other side. There is no such thing as perfect 1 way glass, it would be a contradiction.

that one is easy..... depending on the size of the object lots of bad things could happen quick put on you lead cod piece and run to your underground bunker.... thats what im doing

What in the hell were CT and Jivin discussing on their last show? Something about the hubble spotting a very large object, light years away that just appeared and disappeared days later...

Jokes?

Why do quarter wave dipoles work better than half wave ones?

Then why is a 5/8 wave 2m antenna the most popular choice when a 1/4 wave would be both shorter and more electrically efficient?

[BrianFromIowa]

Q1) Why do people say space is really cold if it is a vacuum? Isn't heat (or the lack there-of) the result of vibration of molecules?

Q2) You have a jar that weighs exactly 100 mg. Air pressure is normal. You remove the lid, and place an insect in there which weighs 10 mg. You close the lid. The insect begins to fly, and hovers in the middle fo the jar. How much does the jar weight?



I don't know the answers to either of these. Answer them, or ask any science questions you don't know the answer to.

:smarty:

Q1. --Scientist Ted-- The lack of heat is an oxymoron!! Sell low after buying molecules for $11.98!!!! -Scientist Ted--

Q2. --Quantum Physics Ted-- It's all about the commodites of the insect! Of course it weighs the same because of the thermal properties of the quark!! The vector will not hold!! --Quantum Physics Ted--

(I know quantum physics had nothing to do with the question, but I like saying quantum)

isn't a higher frequency have a tendency to be less powerful. hence why they use ULF to communicate with submarines?

Correct. ULF is also more secure considering you need a long ass antenna to catch the signal.

could someone splain to me why does my finger smell the same after I dig lint out of my belly button as it does when I sniff my finger after I scratch my ass crack?

wash your finger after you take it out of your ass, you obviously have a cross contamination of stink producing bacteria..... you contaminated your asshole with belly button funk.... highgeeen is your friend

Because the distant particle's spin or flavor or whichever attribute is entangled would change to match it's partners' ostensibly in zero time thereby transmitting information, say morse code in less than the obligitory 30 or 40 minutes predicted by the speed of light.


awhile ago i read about quantum computing where they simulate the same entanglement effect that you are talking about inside a computing environment. they describe using the spin you are talking about as a way to be able to create a bit called a qubit that can be in two states at once. which means you can accomplish four combinations at once of those two states. basically exponentially increasing processing speed. google quantum computing its a great read. if i understand the concept correctly.
