@Blue His skipping of proofs just defeats the whole purpose, a real shame

Q: So Black Holes Actually Merge! In 1/5th of a Second - How?

I've read a lot of conflicting answers in these forums. However, today saw the awesome announcement of gravitational waves. Two black holes merged: http://www.slate.com/blogs/bad_astronomy/2016/02/11/gravitational_waves_finally_detected_at_ligo.html Not only that, they merged FAST. In 1/5th of a...

Real quick: working through the night to finish and ship software by tomorrow. Also will be working on my dental issues this week and next week.

Ok here goes. Three software products, 6 databases, 2 daps etc. One night . . . .

Let me put on some music for inspiration.

This is next level stuff

Probably the most challenging tasks yet

About to make it pop

Need to be on autopilot (code intuitively without giving thought, letting the universe run my vessel for a few hours)

@b_jonas if you mean the kettle question then that's a chemistry question, or at a stretch physical chemistry. For what it's worth I think your boss is correct though I also suspect it doesn't make that much difference.

It isn't something I can easily test as I live in a part of the UK where the water is very soft. My kettle element shows no sign of limescale after at least a decade.

There's also pbs infinite series that's math

Secret

3:51 PM

(has radical idea: What if the sterile neutrino exists just recently in our universe history, thus it does not play a role in the early universe structure)

John Rennie

@Secret you would have to explain why the sterile neutrino exists only now i.e. provide a physically plausible reason for it suddenly appearing.

enumaris

It's shy

Secret

that will require our universe suddenly undergoes a phase transition so some new particles emerges from some symmetry breaking process, which then the burden of proof becomes even higher then proving the existence of sterile neutrinos

definitely not occams razor friendly

It's an interesting question though, do our equipment able to time resolve the different kinds of symmetry breaking in recent (e.g. after it goes transparent) cosmic history

From what I learnt back in cosmology lectures, I vaguely recall there is nothing special at the field level after the era when the universe gone transparent til the present day and the 4 fundemental forces completely separated

John Rennie

The universe going transparent happened at recombination, which was tens of millenia after the Big Bang. Long after the electroweak transition.

378,000 years after the Big Bang

Secret

4:07 PM

yeah. after recombination, there isn't any significant change in the underlying vacuum or background (the matter stuff does not really count as a change because they organised based on what happens to the physics in the background), except maybe the accelerated expansion by dark energy (which we still don't know what that is)

John Rennie

If dark energy is a cosmological constant it has always been present, but its affects only became obvious when the average density of matter dropped below a certain value.

Secret

right

I wonder if future gravitational wave experiments will be able to tell us whether dark energy suddenly switched on, or has been constant throughout the cosmic history

future gravitational wave experiments should be able to reach wavelengths of hours to years, which is the scale where primordial gravitational waves would be

(assuming I remember the gravitational wave spectrum correctly...)

Secret

4:23 PM

Update: Oooo, it's much longer than centuries

nvm then

danielunderwood

This still leaves a big unanswered question about cosmic ray protons, right? science.sciencemag.org/content/early/2018/07/11/science.aat2890

Secret

probably the existence of sterile neutrinos won't affect much about the gamma ray burst events

enumaris

fancy stuff bros

time to implement beam search!

dmckee

@Secret I suppose that sterile neutrino could affect energy transport by neutrinos (usually by making the cross-section for re-deposition smaller) in events that are both energetic and extend over a lot of space.

But aside from that ...nothing. mean, the only way to access the sector is by neutrino mixing, right?

Anonymous

@enumaris I was waiting for fun beans ;)

enumaris

4:30 PM

Only when I feel like it

dmckee

So low cross, section plus small mixing probability (else we'd have found the sector long ago) means interactions are way rare.

enumaris

hence the "sterile"

hmmm implementing beam search is not as trivial as it first appears

Secret

@dmckee yeah, but it is probably a pretty minor modulation on the neutrino energy distribution in the event given how weak the mixing of the sterile neutrino and the standard model neutrino sector is expected to be

@JohnRennie I had the realization a few months ago that the temperature of the surface of the sun and the temperature of the universe when it became transparent are ~~the same within an order of magnitude or so for the same reasons

Also there are the papers from the announcement today

Semiclassical

5:58 PM

@PhysicsMeta editorializes about their own content, generalizes one mod action to "mods are blocking clear answers to questions", dismisses the mod as 'obviously not a biochemist or a particle physicist' despite the question not really being about either...lots of "this is a not a good use of time" warnings going off

dmckee

@GPhys No surprise there.

We define the "surface" of a star for most purposes in terms of the average depth from which radiation penetrates to large radius. In other words we are using "the plasma is transparent" as the criterion for stellar surface, too.

@Semiclassical So, I take it I am not the only person who find that effusive self-praise distasteful, then?

Semiclassical

quite.

now, since I'm not a 10k user on PSE, I can't actually view the deleted answer

so I can't actually judge whether or not his answer was legitimately valuable or not

but that meta post really doesn't give me any reason to expect such

b_jonas

@JohnRennie So should I try to ask that too on Chemistry SE, or would it still be off-topic there?

dmckee

@Semiclassical I would characterize it as very peripherally related to the question, though parts of it are interesting for their own sake.

On the other hands parts of it seem to be the poster riding a hobbyhorse.

@PhysicsMeta @DavidZ I think it is unfair of you to close Michael Bush's meta question. Bad enough that his answer was closed unilaterally by one Moderator, now his rant has been closed by another Moderator! Isn't it clear that he wants to challenge the deletion of his question? I think he is entitled to ask what other users (his peers) think about this.
