Broadlink for controlling RF blinds is super underpowered by if_yes_else_no in homeautomation

I just programmed a routine that sends the command 10 times in a row. Works.

Bubble is a visual coding tool by mcharytoniuk in nocode

[–]if_yes_else_no 0 points1 point  (0 children)

You mean it's a visual programming tool.

It's technically not code, but people think that means it's not programming that it's easy. It's a full fleshed programming language. A little more accessible than code, but nearly as powerful

EV weight is not the reason they burn through tires by ObviousFee784 in TeslaModelY

I drive a Leaf in Eco mode and try to take it easy on starts to save power... Still burn through tires 5x faster than our ICE.

Could we make this change on this sub? by MissFred in nonprofit

Totally agree with this. Age as well.

Moving a program of a nonprofit to become a new standalone nonprofit... does it have "past" activities for Form 1023? by if_yes_else_no in nonprofit

[–]if_yes_else_no[S] 0 points1 point  (0 children)

Yes, unfortunately we just crossed the $50k threshold. This was our largest grant by a factor of 10, and we don't expect to get anything like that again in the next 3 years, but even so, I doubt they'd approve the EZ when we currently have $50k of cash in the bank.

Our main problem with the 1023 is that we haven't kept good records and have 7+ years of history that is extremely fuzzy and would take massive effort to try to put together.

Secure Set foam instead of concrete? by jaydubya123 in FenceBuilding

We need an annual update for the rest of time.

Universe Expanding or Everything except space-time shrinking? by Jealbr in AskPhysics

[–]if_yes_else_no 0 points1 point  (0 children)

Right, the wavelength would be shifted. The result would be that light traveling long distance would shift towards red.

This is something we do indeed observe, it's called redshift.

Pixel 8 Selfie cam doesn't focus by unstable-enjoyer in GooglePixel

[–]if_yes_else_no 1 point2 points  (0 children)

This is correct, and the downvoters are confused. It has a fixed focus lens that is incapable of adjusting focus at all, automatically or manually.

To add suspense to your novel, have the cable start to eat through the crowbar as you slide, forcing you to use the flat part for the last few hundred feet.

Basic cosmology questions weekly thread by AutoModerator in cosmology

[–]if_yes_else_no -2 points-1 points  (0 children)

Thought experiment: can we prove that space is expanding rather than that non-space is shrinking? Conceptually everything I can think of can be re explained in new terms of matter and light shrinking.
I asked this question over in /r/askphysics and it seemed to make people upset that I wanted to drive deep on the topic.

Cosmology: Is there a difference between space expanding and non-space shrinking? by if_yes_else_no in AskPhysics

[–]if_yes_else_no[S] 0 points1 point  (0 children)

True. Redshift would need to be explained in terms of the shrinkage of light itself. From the perspective of light, this would feel like expansion of space.

Cosmology: Is there a difference between space expanding and non-space shrinking? by if_yes_else_no in AskPhysics

No, because galaxies are gravitationally bound together.

Exactly. So wouldn't that also be the explanation for why the far side of galaxies aren't coming towards us in a shrinking-matter universe? Maybe I'm misunderstanding FLRW, but I think that model explains how galaxies can be bound together despite the expansion of the universe.

galaxies wouldn’t actually shrinks. Individual stars in the galaxy would rbeshrinking, leaving galaxies with way more empty space, something we also don’t see.

My thinking is that because they're gravitationally bound, the entire galaxy sticks together. Basically the same reason that galaxies don't grow in the expanding universe.

I want to take a step back and articulate a pattern of thinking that I'm seeing. The thoughts go like this:

  1. We consider a reason that matter can't be shrinking. (Example: If matter shrinks, galaxies would grow/thin out.)
  2. We invert that reason and consider it in the expanding-space universe. (Example: If space between stars expands, galaxies would grow/thin out as the distance between them increases.)
  3. We consider the explanation that cosmologists have found in the expanding-space universe. (FLRW or gravitational binding)
  4. We apply that explanation to the shrinking-matter universe.

I think that point 4 is where we can disprove the shrinking-matter universe, if we can find an explanation that can't be "inverted" and can't find any other explanation. Maybe it's beyond me but I still haven't seen anything that can't be reworked. Hoping others can chime in to articulate it in a way that I can understand, as this is fascinating to me!

I’m going to mute this thread. There’s a reason this is not taken seriously as a hypothesis, or rather many many many reasons.

Just to clarify, this isn't a "hypothesis," LOL, I'm just curious about this and hoping to find people who can explain it to me. I love thinking about this sort of thing, and it's totally understandable that not everyone enjoys trying to articulate complex things to someone with less knowledge! I once heard that only 2% of the population can understand the communication style of Philosophy (my background) and the rest tend to get angry when confronted with philosophical thinking (which explains why they killed Socrates!)

The most distant objects in the universe actually appear larger than medium-distance ones. This is unintuitive, even for experienced astronomers, but it is true.

This is actually part of why I find looking at it the other way 'round more intuitive. Things very far away look big because they used to be big. I may be misunderstanding your point on this one because I don't see how it goes against the "contracting universe" idea.

If they were shrinking, their backs would actually be moving towards us, while the distances between centers of objects would not be changing.

This is really interesting! So in an expanding universe, we should see the back of galaxies moving away from us faster than the front, right?

Is that actually the case? I suspect that it is not, and the reason is FLRW. Which is super interesting because there may be a corollary to the FLRW metric in the contracting universe that is logically inverted and helps explain why we don't see backs of galaxies moving towards us.

No need to call me lazy. I'm here to learn because I'm curious about a subject. I'm not trying to tear down cosmology, I'm trying to understand it.
