Actually it could not continue forever. Two objects orbiting one another will cause tidal forces which gradually induce rotation on the objects. This is energy that is taken away from the orbital kinetic energy, eventually resulting in orbital decay. (see tidal locking)
@rchoetzlein : and you would be wrong, they would continue forever due to Newton's simple laws (an object in motion stays in motion unless acted upon). If 2 objects were all that were in the universe, and they had an orbit of exact space, then those objects would continue forever. But this isn't such a simple universe and we have almost infinite amount of energy vectors acting upon each other. "Entropy" is what you are thinking of, and is the cause of the universe expanding.
@sabriath: im sorry but the post you are replying to is correct. you are correct also, but only a bit. rotation will be induced in the objects, and from conservation of momentum, the orbit speed will slow and object rotation speed will increase. the end result will be 2 objects, each rotating on its axis, and the sum of the momentums of both objects still = to the original momentum when they were orbiting.
You might like Victor Shauberger's idea that the ocean water is colder and denser at depth. All is needed is a channel to get that water to the surface. Then you got flow forever which you can apply a turbine. Free energy lives.
this should be very small. but in theory if you give a superfluid momentum it could generate a superfluid fountain of any size. it's jsut we can't make a vaccuum big enough to accommodate a large superfluid fountain.
i need help can i use this as an investigatory project? I think its too hard . can I use the helium in baloons and produce the fountain effect ? or if its not applicable i'll just make a research .please help me thanks ..
The fountain phenomenon is powered by gravity, it's also sort of like a pendulum in that way. When a pendulum drops it will reach the exact same height on the other side, except for the fact that it looses energy to friction in the pivot and to air resistance. If no such resistance existed the pendulum would swing forever, which is the case for the superfluid.
with the one little hitch that superfluids don't exist unless extremely cooled, thus making it a very unviable candidate for any sort of perpetual motion devices, in case some fanatics are seeking that sort of miraculous use for superfluids :)
well perpetual motion does exist in a way, the moon rotates around the earth without losing energy, but it doesn't generate energy either, it's in a state of rest while being in motion relative to the earth. Therefore Perpetual motion cna exist in a frictionless enviroment, but the moment you try and tap that energy somehow it's lost. Thats what people don't seem to understand, it's not generated energy, it's potential energy.
Now that you mention it, you are actually wrong, albeit on a scale that is very strict - The moon does rotate around the earth without losing energy, however it does gain distance, and this gradually(very slowly) diminishes the gravitational bond between the two bodies enough that when stretching towards near-infinity it will be broken ; the same is true for all conceived perpetual motion, there is always either a tiny loss or degeneration of the system or its components.
@GronTheMighty however, if you made two heavenly bodies in a perfect orbit, then their motion would continue forever. This doesn't violate any laws of physics.
Like you say though, the real problem with perpetual motion is a properly closed system.
I'm afraid again you're wandering off into wishful thinking - any sort of gravitational orbit comes to an end eventually with either one of the gravitating bodies to be slung away from the other out of the orbital, or the weaker one being drawn closer and closer to the stronger - in even gravitational pull situations both bodies will still end up either colliding or seperating given enough time.
Keep in mind, 'forever' is a time longer than any other span
yes, but my point is that its theoretically possible, if you could set it in a perfect, non-decaying orbit. Most people seem to think this violates some law of physics.
The problem is it would be theoretically sound yes, but an orbit will always have a decay in one form or the other - gravitational decay, drag decay, tidal force decay or whats known as 'bulge decay'.. even with perfectly round spheres of the exact same size in as perfect an orbit as we could position them they would both still be influenced by gravitation from elsewhere in the universe since there is no known way to hinder gravitational forces in order to 'close' the system off
in other words i would not say there is any law of physics that i know of that hinders the theoretical alignment of two or more celestial bodies in a perpetual orbit forever, but there is a variability that is known to cause orbital decay that we have absolutely no clue whether it is ever going to be possible to affect...
Even so, you're talking about merely making a perpetual motion happen, which is theoretically sound.. deriving energy from it however is not, as you know ;)
Orbital decay is due to tidal forces generating friction in the celestial bodies. Friction generates heat which is then radiated into space. If you can think of two orbiting celestial bodies that are made of a material that can handle tidal forces without generating friction they would cool to zero kelvin and orbit each other forever.
@sleepingeye You are correct, if you propose a system that is seperate from the rest of the universe.. or in other words exists in a universe of its own. Then yes, two bodies made of a frictionless material can orbit eachother perpetually.. but you still cannot derive any energy from this without ruining the perpetuality of the system :\
In our universe, to my knowledge we also don't have any frictionless materials, only materials that are close to frictionless... like superfluids :)
@GronTheMighty If the moon is going away from the earth, as you say, this means it gains energy with respect to the earth's gravitational field or the earth's gravitational field is getting weaker. How does that work?
@sleepingeye Neither is true ; on the earth we have oceans that are affected by the orbit of the moon and it's gravitational pull ; due to the moon orbiting the earth, this creates a tidal effect on the earths oceans - the distance between the earth and the moon makes this tidal effect 'lag behind', which is what causes the slight increase in distance - if you will, a weakening of the proportion of the gravitational pull of the earth on the moon to the moon on the earth's water.. i think? :s
In the case of I.e the Fountain effect of superfluids, the degeneration takes place as absorbsion of heat from the surrounding environment which accumulates slowly untill the superfluid is no longer frictionless and then rapidly it loses momentum untill it comes to a near-complete halt when the differential in temperature is diffused.
At this temperature, the helium fluid's energy stated is "quantized", that is, it can only change by finite increments. It will not slow down due to friction or gravity unless the drag is more than this quantized step so it is able to move up surfaces in order to reach lower ground.
is this just a shot flipped upside down to make it look like a fountain?
if its really one..how do they pump it? must be extremely hard to pump a superfluid under any kind of usable pressure.. or am i way off on that.. someone explain the system they use to accomplish this?
i think it has to do with the weight of the upper portion of the fluid being pulled down by gravity and having a higher mass than the lower portion of the fluid will push it downwards and then up the tube because of the lack of friction, the lower portion of the fluid will be pushed up the tube with the same force that the upper more massive part of the fluid is being pulled down by gravity.
"The glass tube is heated and packed with fine powder at the bottom. Called the superfluid fountain, it occurs because the superfluid outside of the tube rushes in to cool down the superfluid that has been warmed by the inside of the tube. (Allen, the co-discoverer of superfluidity, is said to have discovered the effect after he shined a pocket flashlight onto a glass tube of liquid helium.)" Taken from SciAm.
nope, its like water in a closed soda bottle, some evaporates until the air is saturated, then it condenses, that dries the air and more water has to evaporate making an endless cycle which in fact a little endothermic.
no, superfluid are known to have none or ridiculously low amounts of friction. The type of condensation fluid motion can be thought of like a wheel. if the wheel has no friction, one side will counterbalance the other so molecules going down and molecules going up are really just trading energy in a closed system. Its nothing more than momentum with zero friction, but instead of a solid wheel, its done by fluids.
well i explained why its perpetual or nearperpetual, because superfluids have no friction, as electricity is to a superconductor. the reason why their is an exchange of gas to liquid. the moisture inside is more than the temperature and pressure's dewpoint, water condenses like rain reduces the amount fluid that is a gas and creates a vaccum where gas was and causes the fluid to boil from lowered pressure.
when the substance condenses, it becomes more dense(hence the word"condense"), so the gas in the chamber has less pressure. i.e. water is 17,000x more dense than steam. if u had a container full of steam and the steam condensed, the absence of steam creates a vaccuum effect.
I expect many comments about how wrong I am, but basically superfluids have no viscosity, which means no resistance to flow. This somehow makes the fluid creep up the sides of it's container and drip down the sides. In this case, it's made a fountain. A self propelled and thus infinitely spouting fountain.
I understand the zero viscosity. But what I can't understand is the fact that it slows down the speed of light down to a very slow speed.
Anyway a superfluid is a fluid that can flow at anytime with no resistance to flow/ no viscosity, slow motion and the speed of light down very slow speeds.
Now at the same time, it's also a state of matter that is just between a fluid and gas,meaning that there is also a supersolid, whic has a medium viscosity. Am I right?
The speed of light is constant because the carrier of light (ether) is carried within gravitational fields. Flowing ether IS what we call gravitational fields. Things fall according to the gravitational field, because they are carried with the ether, like a stick in a river.
People who followed Einstein and misinterpreted him thought they have proven the nonexistence of the ether. The only thing they had proven was the nonexistence of a STATIC ether.
Im pretty sure Superfluid and BEC are two different things. Superfluid can be created by lowering the temperature of using super cooled hydrogen. BEC requires magnetic cooling or laser cooling to exist and can apear at a tenth of a billionth of a degree
Yeah, they are two different things. This happens at 4 kelvin
While BEC occurs at 0.00000000001 kelvin, the atoms give of wavy like versions of themselves instead of just dots like in solids liquids and gases etc. They get an identity crisis so they dont know which atom they are in the substance and BEC can actually slow down the speed of light which... Superfluid can't do.
Interesting how through the process of experimentation scientist find hidden nature secrets. There are many, many secrets still waiting to be discovered. Unfortunately they're getting harder and harder to find. They will provably require a different way of thinking; thinking outside the box if you will. Just like Clerk Maxwell did when he figured out with pure mathematics the composition of Saturn's rings. Continued-
Albert Einstein and the discovery of relativity utilizing only his brilliant mind without the need of a lab or computers and of course let's not forget Sir Isaac Newtown with the discoverer of the universal laws of physics. I'm 39 now I just hope I live long enough to see more amazing discoveries. Can't wait until we humans go to mars and setup a lab there. As human beings and perhaps through religion influence we are led to believe we are the only living creatures in the universe, that's BS.
Actually, in 1999 a Danish physicist named Lene Hau used a superfluid to slow down a beam of light to about 17 metres per second, and in 2001 actually momentarily stopped a beam.
Wrong, the reason why light slows down in a medium is because unlike what is seems light isn't traveling a straight line, it's bouncing and bending past atoms, a very dense medium will slow down light more etc but only from our perspective, light is still moving at the speed of light.
I believe light is a longitudinal wave in a compressible nonviscous dynamic ether. The ether is thought to be denser around massive particles, because of gravity. In my theory gravity is due to ether flowing concentrically to massive particles. If you have a lot of massive particles together, they suck in a lot of ether. That means the ether gets less dense (like air, when it is fast --> venturi). That's why the light (ether-waves) are slower in dense materials.
Actually the clarification needs to come from the use of kelvin (K). Temperature in kelvin is not referred to in "degrees kelvin," just kelvin. So it is 1 K, or "One kelvin". You may note that when writing the unit it is K, with no degree symbol preceding it.
It's a liquid that has no friction. What you are watching is liquid Helium at 271 degrees Centigrades below zero (456 F below zero) shooting out of a tube just because of a small temperature difference. It is called the fountain effect.
These would be great additions to a music video, if they haven't already. Or maybe you should add music to them?

The speed of light is only constant in a vacuum. Light passing through other materials is slowed down.

Where does the speed of light enter in this? lol

Wrong, the reason why light slows down in a medium is because unlike what is seems light isn't traveling a straight line, it's bouncing and bending past atoms, a very dense medium will slow down light more etc but only from our perspective, light is still moving at the speed of light.

My theory:
I believe light is a longitudinal wave in a compressible nonviscous dynamic ether. The ether is thought to be denser around massive particles, because of gravity. In my theory gravity is due to ether flowing concentrically to massive particles. If you have a lot of massive particles together, they suck in a lot of ether. That means the ether gets less dense (like air, when it is fast --> venturi). That's why the light (ether-waves) are slower in dense materials.

I read that they reached BEC at 4.5x10^-10 and i think it was reached at higher temperatures aswell =D

actually a superfluid is formed long befor it becomes BEC. Also BEC has been cooled down to to ten billionth of a degree

a degree is no where near absolute zero you mean
a kelvin

well it could be as it is degrees centigrade or degrees kelvin, degrees is fine it just needs clarification

Actually the clarification needs to come from the use of kelvin (K). Temperature in kelvin is not referred to in "degrees kelvin," just kelvin. So it is 1 K, or "One kelvin". You may note that when writing the unit it is K, with no degree symbol preceding it.

I've always heard it refered to as degrees kelvin but then again that might be my teachers that are wrong you never know. oh well.

Yeah its Kelvin not "degrees Kelvin". Common mistake though.

what's superfluid?
infestedfrank 4 years ago
It's a liquid that has no friction. What you are watching is liquid Helium at 271 degrees Centigrades below zero (456 F below zero) shooting out of a tube just because of a small temperature difference. It is called the fountain effect.

So the liquid flows from the region of high temperature or the low temperature?

Isn't it impossible to set up temperature gradients in a superfluid due to it having infinite thermal conductivity?
