John Duffield

@heather : yep. See LIGO.

When an ocean wave moves through the sea, the sea waves. When a seismic wave moves through the ground, the ground waves. And when a gravitational wave moves through space, ........... waves.

Secret

The metric has an explicit time dependence which is periodic, you can consider that to be waving

Sir Cumference

@JohnDuffield I wave, you wave, we all wave

That answer "what waves?"

John Duffield

@Secret : the metric is an abstract thing to do with measurement.

heather

not sure what you want to discuss @JohnDuffield

It's the main reason I am better at QM than GR because GR screw up the intuitive notion of distance and time which are the two things I rely on to build a memory palace that is used to make sense of the concepts

@heather : the nature of gravitational waves. What's waving?

heather

@JohnDuffield spacetime

diobuc eulb

@Phase it’s figurative dummy

for now at least!

Sir Cumference

@JohnDuffield Is this waving

John Duffield

17:15

@heather : the only problem with that is that spacetime models space at all times, so there's no motion in spacetime.

Secret

@JohnDuffield but all observers can only see one slice of the time at a time, thus they perceive a time dependence on the set of distances (and time lag) between objects, and this varies periodically and thus waving

John Duffield

@Secret : if distances change as a gravitational wave passes through, what's waving?

heather

ask your question on P.SE @JohnDuffield I guess. I'm no physicist.

much as I'd like to be one.

John Duffield

@heather : I know the answer. The answer is space.

diobuc eulb

17:19

space is like the sea

and gravitational waves are dolphins

John Duffield

A gravitational wave moves through space. LIGO measures distance variations via an interferometer.

Has anybody ever spotted William Kingdon Clifford's space theory of matter? It dates from 1870.

_I hold in fact_

_(1) That small portions of space are in fact of a nature analogous to little hills on a surface which is on the average flat; namely, that the ordinary laws of geometry are not valid in them._

_(2) That this property of being curved or distorted is continually being passed on from one portion of space to another after the manner of a wave._

Secret

@JohnDuffield It's the same as what happens in electric fields in EM waves. the field is periodically varying in strength, but there is no charge that is responsible for it, thus it is the field itself. Similarly, spacetime is waving (the time aspect shows itself by the time lag and the redshifts of the light that passes through it)

Sir Cumference

@JohnDuffield What made you bring this up?

Secret

If it is only space is waving, there will be no periodic variation in time lag observed, which is not the case in the LIGO experiment

2

John Rennie

@Secret I would be cautious about assigning actions to spacetime. Spacetime is a purely mathematical construct. A gravitational wave is an oscillation in the metric. The question what is really waving is unanswerable in GR. You need to go and ask a philosopher with too little to do.

Can anyone help me with this?

in Problem Solving Strategies, 3 hours ago, by Mr. Xcoder

Hello people! I have this pyramid $ABCDE$, and there is a current of intensity $I$ entering the circuit through $A$ and exiting through $C$. Each wire ($AB$, $AC$, $AD$, $AE$, $DE$, $BE$, $CB$, $CD$) has resistance $R$. Noting that the structure is symmetrical when "cut" with the plane $(ABE)$, I've sketched this equivalent circuit. Can anyone confirm it is correctly drawn?

John Duffield

@SirCumference : Something Phase said this morning. This.

diobuc eulb

sometimes being rational is not as rational as being irrational when debating an irrational person.

Secret

@JohnRennie Well, from an instrumentalist point of view, we see the effects in terms of the change in distance and the time lag, thus to a superficial extent, this is sufficient. However as you said, since these are the observations, ultimately what is waving may be in the philsophical domain. It's a similar idea really, we can ask what is electric charge, and eventually it will go philosophical

John Duffield

@Secret : spacetime is static. It models space at all times. It doesn't wave.

John Rennie

17:24

@diobuceulb General relativity is a mathematical model. If you don't understand the maths you don't understand GR. End of story.

Sir Cumference

@JohnRennie What maths

I've been asking for months

John Duffield

@Secret : I know what electromagnetic charge is. And it isn't philosophical.

Secret

@JohnRennie In science, we only have models to to describe our experimental results, so our models can only get so far. The rest is metaphysics as you said

diobuc eulb

@JohnRennie well tell that to JD

John Rennie

@SirCumference and we've been telling you for months. The fact you can't decide whether you like diff geo or topology more isn't Einstein's fault! :-)

Secret

17:29

@JohnDuffield technically it does not change if you look at it from the outside, but since every observer trace a trajectory within spacetime, they only see the change in space wrt their proper time, thus to a moving observer, it looks as if it is waving, if that's a rough way to describe it

John Duffield

@Secret : an observer doesn't "trace a trajectory within spacetime". There is no motion in spacetime. You don't move along your worldline. Your worldline represents you at all times.

Q: Why is chemical potential equivalent to a true potential?

My K&K thermal physics testbook says chemical potential is equivalent to a true potential: the chemical potential is equivalent to a true potential energy: the difference in chemical potential between two systems is equal to the potential barrier that will bring the two systems into diffusive...

Would anyone help me review the comments under the answer? I am not very sure if the comments are reliable.

Secret

@JohnDuffield but we only see one moment in time, not the whole time at once in our life, so we are experiencing movement of sorts in order to have things changing from our point of view

John Duffield

@Secret : yes, we live in a world of space and motion. Things move. Things like waves. They move through the sea, or the air, or the ground, or space. Now, do you know of any waves where something doesn't wave? Because I don't.

Secret

well, since from the above we conclude (at least from an instrumentalist, and also from the mathematical model view) what is waving in gravitational waves (the rest is metaphysics) thus so far everything that is a wave has something that can be said to be waving, so I dont see any issue with your query here

Shing

17:37

In general relativity, is the energy density of gravitational field zero?

John Rennie

@Shing that depends what you're asking.

John Duffield

@Secret : the issue is that people dismiss what they don't understand. There is a great deal of ignorance out there.

John Rennie

Energy is a tricky thing to pin down in GR.

Shing

@JohnRennie I was thinking if the detection of gravitational waves suggests gravitational waves carry energy (such that interact with the detector)

John Rennie

17:40

@Shing The energy of gravitational waves is decsribed by the gravitational stress–energy–momentum pseudotensor. But this is a curious object because coordinates can always be chosen in which it is zero.

The energy of the gravitational field can't be simply expressed as a function of position.

John Duffield

@Shing : see what Einstein said here: "the energy of the gravitational field shall act in the same way as any other kind of energy"

Field energy is positive energy. It's a popscience myth that gravitational field energy is negative. It's been popularized by people like Lawrence Krauss who claims gravitational field energy is negative, and that the total energy of the universe is zero.

I have to go I'm afraid. Bye for now.

Mercury-Redstone 1

Mercury-Redstone 1 (MR-1) was the first Mercury-Redstone unmanned flight test in Project Mercury and the first attempt to launch a Mercury spacecraft with the Mercury-Redstone Launch Vehicle. Intended to be an unmanned sub-orbital spaceflight, it was launched on November 21, 1960 from Cape Canaveral Air Force Station, Florida. The launch failed in a peculiar fashion which has been referred to as the "four-inch flight". == Test background and launch failure == The purpose of the MR-1 flight was to qualify the Mercury spacecraft and the Mercury-Redstone launch vehicle for the sub-orbital Mercury...

As discussed here math.stackexchange.com/questions/281931/… and here mathoverflow.net/questions/21171/… this answer doesn't sound quite right; for instance, no integral multiple of $2[S^1]$ is the fundamental class of a submanifold of $S^1$).
