When helium 4 becomes a super fluid does the proper time change, can this be detected?
This understanding is not correct. There is nothing such as a unique way of identifying a "point in space" as that would be coordinate dependent. Proper time is an invariant quantity related to a clock following a particular world line.Ripperooster said:My understanding of proper time:
Every point in space is affected differently by time and gravity so has a different relative time, this goes for the 1st floor and the 50th or my toe and my eyebrow.
You started off talking about proper time and now you have switched to relative time. Time relative to WHAT? Do you mean the proper time throughout the life of the material? If so, that question has already been answered.Ripperooster said:Can the relative time of a superfluid be proven to be constant though it's change or phase change as you put it.
I believe tick rate differences have been measured at height differences as low as 1m, so differences between your head and toes are detectable. But this is the gravitational field of the Earth. My number above is a back-of-the-envelope estimate of the equivalent effect due to the gravity of a jar of liquid helium (or, indeed, a jar of water) and sounds optimistic on reflection. Its gravity just isn't important to anything.Ripperooster said:I understand the immeasurable diffences of my head and feet but I'm sure differences in relative time have been shown at the top and bottom of a skyscraper.
As phinds says, relative to what?Ripperooster said:Can the relative time of a superfluid be proven to be constant though it's change or phase change as you put it.
The clear answer is “no”. So you can come on up out of the rabbit holeRipperooster said:I don't know where I got the idea from, but I couldn't find a clear answer, which usually sends me down the rabbit hole..
Proper time change refers to the changes in the flow properties of helium 4 when it transitions into a superfluid state. This includes changes in density, viscosity, and flow rate.
Helium 4 transitions into a superfluid state when it is cooled to extremely low temperatures, typically below 2.17 Kelvin. At this temperature, the helium atoms lose their individual identities and behave as a single entity, exhibiting unique quantum properties.
The main effects of helium 4 superfluidity include zero viscosity, zero thermal resistance, and quantized vortices. These properties allow for extremely efficient heat transfer and unique flow behavior, making it useful in various applications such as cryogenics and superconductivity research.
Helium 4 superfluidity plays a crucial role in the study of quantum mechanics, as it allows for the observation and manipulation of quantum phenomena on a macroscopic scale. Its unique properties provide a platform for testing and refining theories in quantum mechanics.
One of the main challenges in studying helium 4 superfluidity is achieving and maintaining the extremely low temperatures required for it to manifest. This requires specialized equipment and techniques, such as dilution refrigeration, to cool helium 4 to its superfluid state. Additionally, the behavior of helium 4 in superfluid state can be unpredictable and difficult to control, making experiments and observations challenging.
