Does the ΛCDM term violate strong energy condition?

@JohnDuffield ... because they don't exist. But a CTC is defined as a closed curve that you can travel round. If you can't travel round it the curve isn't timelike.

0celo7

That's never been entirely clear to me.

@JohnDuffield What? Why not?

John Rennie

@0celo7 as I recall, it depends on the dark energy equation of state. A cosmological constant doesn't violate the stong energy condition but some variants of dark energy do.

John Duffield

@John Rennie : you can't travel along a worldline. There's no motion in spacetime. Whoever defined a CTC as something you can travel round got it wrong. It was probably Wheeler. See my answer here where I referred to Palle Yourgrau saying he conflated a circle with a cycle. There is no way you can move such that everything else not only moved back to where it was, but never moved at all.

0celo7

@JohnRennie Do you have any references?

I'm reading Hawking-Ellis and I'm wondering how their theorems work with modern models.

Q: Does negative energy density (i.e. weak energy condition violation) create closed timelike curves?

I remember reading something about Stephen Hawking denying the fact you can't make CTC's (Closed Timelike Curves) without weak energy condition violation. If this is true, where do the light cones point to in the $t$ direction? On the end of the right and left, the cone points up (future) but...

0celo7

@JohnDuffield You're gonna have to source "there is no motion in spacetime"

John Rennie

@0celo7 It's the block universe idea

Eternalism (philosophy of time)

Eternalism is a philosophical approach to the ontological nature of time, which takes the view that all points in time are equally "real", as opposed to the presentist idea that only the present is real and the growing block universe theory of time in which the past and present are real while the future is not. Modern advocates often take inspiration from the way time is modeled as a dimension in the theory of relativity, giving time a similar ontology to that of space (although the basic idea dates back at least to McTaggart's B-Theory of time, first published in The Unreality of Time in 1908...

John Duffield

@John Rennie : I forgot the URL, see my answer here: physics.stackexchange.com/questions/83064/…

0celo7

@JohnRennie Paywall...you bastard

:P

John Rennie

But in this context it's a bit of a red herring because motion is defined as the evolution of position with proper time.

i.e. the proper time parameterises the motion.

So claiming that motion doesn't exist in GR is really down to how you define motion.

My own view is that GR's concept of motion should agree with what I personally experience, and this is exactly how the parametrisation using the proper time works.

5:09 PM

Well, it's been (more than) an hour... time for me to go sleep

John Duffield

@0celo7 : see Ben Crowell saying the same here: physics.stackexchange.com/questions/33840/…. Spacetime is the block universe, you need meta time to move in it.

John Rennie

@DavidZ Have a good mountain climb.

Which mountain BTW?

I did a quick Google for mountains in Vietnam with no obviously applicable results

David Z

I have no idea, I'm meeting some people and they will show me where

It's a small mountain

more of a hill really

There are no big ones near here as far as I know

John Rennie

How would you feel if you went to a website, asked a question you care about, was down voted and unanswered. I wouldn't come back. — Alex 25 mins ago

John Duffield

@John Rennie : motion is motion. You can see it. It is empirical. Your proper time is given by your clock reading. And inside your clock, a pendulum moves. Or cogs move. Or a piezo-electric crystal. Or something else. The proper time is defined by motion, not the other way around.

ACuriousMind

@KyleKanos To quote you a while ago: sigh

Gaurav

@KyleKanos Sounds like a paradox to solve for the great minds in the room.

John Rennie

@KyleKanos I think Alex's answer was well intentioned, and it's a shame to downvote, but it's a rubbish answer.

Kyle Kanos

@Alex: My first question here was downvoted and left unanswered for about a year. I came back; repeatedly. — Kyle Kanos 13 secs ago

Gaurav

@KyleKanos He's upset with the downvote on the answer right ? Which question is he talking about ?

Kyle Kanos

He's upset with the downvotes on the question itself

I think that the downvotes on the question are probably unneeded

It's not a terribly thought-out/researched question

Q: What are mesons and leptons?

What are mesons and leptons? I get decay processes where the decay products are leptons (electrons, positrons, neutrinos, mesons etc.). What are these?

standard-model mesons leptons

Gaurav

Well, I think it's always better to close such questions right away rather than downvoting them. It serves the purpose better.

John Rennie

"not a terribly thought-out/researched" - it shows no research effort at all.

@Gaurav My response to questions like that it to vote to close but not to downvote.

ACuriousMind

@Gaurav We're undecided on whether or not to close such questions

John Rennie

5:20 PM

Although in this case all my close votes are used up

@ACuriousMind You may be undecided, we are not.

ACuriousMind

@JohnRennie Look at the poll there (the two answers by alemi) - it's no clear decision at all

John Rennie

@ACuriousMind the point I'm making is that I have decided I will (usually) vote to close questions that show no effort.

ACuriousMind

Ah, alright then

John Rennie

This is a democracy and others may vote to close or keep open as they will

But I consider it an important principle that the Physics SE best helps those who help themselves

0celo7

@JohnDuffield Perception of time is not understood, and I think you're being bold to place an interpretation on it.

HDE 226868

@Ocelo7 I love how DavidZ left the room just as you posted that.

John Rennie

My point is that I have a precise definition of the phenomenon I call motion

You employ a different definition

That's OK, since we both understand each others definitions there need be no misunderstandings.

0celo7

@HDE226868 Probably to initiate the permaban

Time to fire up the VPN...

John Duffield

@John Rennie : perception of time is understood. Time travel is science fiction. Hawking's Chronology Protection Conjecture is popscience bunk. See this answer: physics.stackexchange.com/questions/83064/… . If you're not happy with it, ask a new question and I'll give more detail.

John Rennie

@JohnDuffield "perception of time is understood" - you know how the brain works?

0celo7

5:28 PM

@JohnRennie Durr, neurons fire. Not too hard to understand.

John Rennie

@0celo7 you're not taking this seriously, are you? :-)

Anyhow, I have to go. Well, I don't have to, but I'm halfway through a book on supercontinents and I'm itching to get back to it.

HDE 226868

Can I suggest that this question either be left closed here on Physics or migrated to HSM, where we can merge it? Two copies always give me a headache.

John Duffield

@John Rennie : your definition is wrong. Hold your hands up. That gap between them is a space. Space is empirical. Now shake your hands. That's motion. It's empirical too. I can show you space and motion. You can't show me time. When you show me proper time you're just showing me a cumulative measure of motion. I'm not just making this up. Go and look at A World without Time: The Forgotten Legacy of Godel and Einstein. And no, I don't know how the brain works. But I do know how clocks work.

Slereah

0celo7

Silly @Slereah, rigorous theorems are popsci.

Slereah

Plus it's a theorem to prevent time travel from happening

ACuriousMind

@0celo7 Even knowing you aren't serious - reading that makes me shudder :P

Slereah

Surely you should appreciate it

Kyle Kanos

@0celo7 Sadly, that is really his only argument.

ACuriousMind

@Slereah Why should we appreciate something that forbids time travel (thus, a fortiori, Doctor Who)?

Slereah

5:49 PM

Because Duffield is a grumpy man that hates everything

Every question about some theoretical thing is met with sneers from him!

0celo7

@ACuriousMind As someone who's trying to make sense out of Hawking's theorems, thinking of any spacetime topology theorem as popsci makes me shudder.

John Duffield

@0celo7 : it's not an appeal to authority because I also refer to the evidence. Open up a clock and you don't see time flowing through it like it's some cosmic gas meter. If you try to dismiss that, and Einstein too as some "appeal to authority", you ain't talking physics.

Slereah

All the cool kids love convex spacetime neighbourhoods

2

John Duffield

@Slereah: yes the chronology protection conjecture is popscience. You can't move backwards through time because you don't move forward through time. A clock clocks up some kind of regular cyclical internal motion and shows you some cumulative result called "the time". It doesn't literally measure the flow of time. Or the passage of time. And it certainly doesn't measure its own "motion through time".

ACuriousMind

5

Q: Why do clocks measure arc-length?

Apologies in advance for the long question. My understanding is that in GR, massive observers move along timelike curves $x^\mu(\lambda)$, and if an observer moves from point $x^\mu(\lambda_a)$ to $x^\mu(\lambda_b)$, then his clock will measure that an amount of time $t_{ba}$ given by the curve'...

general-relativity special-relativity spacetime time relativity

Slereah

6:01 PM

The point is that a geodesic cannot cross itself

Independantly of time flow notions that you may philosophize abour

John Duffield

@0celo7 : what should make you shudder, is cargo-cult crap and popscience nonsense masquerading as serious physics. @ACuriousMind: no, observers do not move along timelike curves. There is no motion through spacetime. There is no motion through time. The motion is through space.

ACuriousMind

@JohnDuffield There is no fixed notion of "space" or "time" in arbitrary spacetimes.

Slereah

You can't even define a time slicing in arbitrary spacetimes, really

you might not even be able to define a future light cone!

Hard to define achronal slices when you have CTCs!

John Duffield

@Slereah: no, I'm not some grumpy old man who hates everything. I'm a guy who hates cargo-cult trash, particularly that which is presented as Einstein's relativity, but which flatly contradicts Einstein. @ACuriousMind: spacetime is an abstract mathematical space. The Earth is not surrounded by spacetime. It is surrounded by space.

Slereah

You don't really justify in what way it is not Einstein's relativity

It's a frequent feature of Lorentzian manifolds to have closed timelike curves

As shown as early as 1942

(Although I don't think it was really discussed until the 50's)

Whether or not you think that corresponds to something physical is another matter

And it's kind of the goal of the chronology protection theorem to show that it is not

John Duffield

6:09 PM

@Slereah: look up at the clear night sky. Can you see a worldline? Or a lightcone? How about a CTC? No, because all these are abstract things. Einstein did not confuse such abstract things with reality. Or space with spacetime. The map is not the territory. Nor should you.

ACuriousMind

@JohnDuffield ...so? The motion through space is equivalently encoded in a worldline.

Slereah

We are talking general relativity here, not epistemology

Knowing to which extent a theoretical model applies to reality is important

And it is not a trivial thing either

And knowing the mathematical details of a theoretical model, even if it does not apply to reality, is not pop science

John Duffield

@ACuriousMind: yes, and it's motion through space. Not motion along that worldline. So you don't travel along a CTC. There is no way you can move such that everything else not only moves back to where it was, but never moved at all. @Slereah: see my answers where I challenge "Kip Thorne relativity" and back up what I say with Einstein references.

Slereah

In what way does it invalidate what I say

ACuriousMind

@JohnDuffield I don't know where you draw that certainty from - in geometries with CTC, there is no clear cut notion of "time" or "space" because you can't define time slices properly, as said above. It's completely unclear what "motion" in the sense of "through space" would be in such a geometry.

Quoting Einstein on this is not particularly helpful because we have advanced a lot in our understanding of the mathematical structure of GR since his time.

If you understood the physics you'd know why the mathematics is handwaving trash. @ACuriousMind: no, you have not advanced your understanding. You've gone backwards.

"Our test campaign cannot confirm or refute the claims of the EM Drive"

ACuriousMind

@KyleKanos It does? Oh, well...

Kyle Kanos

@ACuriousMind Mac is a Unix OS ;)

Slereah

It's not even NASA

It's just Harold White

Well this recent presentation is neither NASA nor White

HDE 226868

@Slereah They quoted another scientist, at least.

ACuriousMind

@KyleKanos Yeah. I should've thought before typing ;)

Kyle Kanos

@ACuriousMind Happens to the best of us

@KyleKanos can con_irm

Slereah

Yeah but like

Dudes working at NASA are not NASA

I suspect the global consensus of NASA is not towards the EM Drive

@HDE226868 Mind you, any scientist with a career to protect will be pretty cagey about the line between beginning to think there is something worth looking into and actually claiming that it works.

Slereah

As he should be

Experimental physics isn't easy business

0celo7

I have to take the whole key mechanism out

Slereah

You need to be patient

0celo7

the problem is much deeper than initially assessed

HDE 226868

@dmckee Hence the cautious words.

Gotta go, but if anyone knows anything about my Orcus mini-question, I'd love to get a ping. Thanks.

I just found the answer for this closed question;

Quasar

Quasars (/ˈkweɪzɑr/) or quasi-stellar radio sources are the most energetic and distant members of a class of objects called active galactic nuclei (AGN). Quasars are extremely luminous and were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, that appeared to be similar to stars, rather than extended sources similar to galaxies. Their spectra contain very broad emission lines, unlike any known from stars, hence the name "quasi-stellar." Their luminosity can be 100 times greater than that of the Milky Way. Most quasars were formed...

A grouping of two or more quasars can result from a chance alignment, physical proximity, actual close physical interaction, or effects of gravity bending the light of a single quasar into two or more images.
