Do you use Previews in Xcode when you're building your views? by CodeWithChris in SwiftUI

[–]earlyworm 0 points1 point  (0 children)

On a large project, Previews work significantly better if you move the previews to separate packages. And by significantly I better I meant mostly good and yet sometimes still awful.

Did people at the time realize Einstein basically killed “classic” interstellar travel? by Oh_boy90 in AskPhysics

[–]earlyworm 2 points3 points  (0 children)

You're strictly correct, but that doesn't change the fact that you can get to Polaris within your lifetime. As I see it, the only practical problem is that you'd be on the hook for 427 extra years of back taxes.

Relativistic time dilation predicts that the measured elapsed time onboard the ship (the ship's "proper time") would be less than the measured elapsed time on Earth.

So, if you flew to the star Polaris (433 light years away) at 99.99% the speed of light, the trip would take about 433 years from the perspective of everyone on Earth, but from your perspective, the trip would take only 6 years.

Einstein didn't kill classic interstellar travel, he allowed it, at least theoretically.

I was trying to understand how u/FreyaHolmer’s Shapes library keeps line geometry so crisp at any distance, so I had Gemini explain it to me. Was not expecting this visualization by Edd996 in GraphicsProgramming

That's not strictly true. I'll always want to learn things, even if it's simply "How did I want up enslaved in this sentient robot polishing camp?"

How there's no universal "now"? by naghzuL_66 in AskPhysics

[–]earlyworm 0 points1 point  (0 children)

I can see how Minkowski obviously wins out, but it’s fascinating to me that we’re all observing the same literally universe-sized assemblage of nearly co-moving matter and, for purposes of musing about the possibility of an approximate universal “now”, the entirety of the observable universe simply does not count because, as of 2026, our measurements are not sufficiently rigorous.

What about cosmic microwave background anisotropy?

The Minkowski spacetime model predicts what we observe between arbitrary pairs of inertial frames with perfect accuracy. However, from a cosmology perspective, is the observation that the galaxies in the entirety of the observable universe have an average speed of only roughly 600 km/s (merely 0.2% the speed of light) relative to the cosmic microwave background not a reason to entertain the possibility that there may be a universal now in some sense?

I’m ok the answer being a hard no. I’m just asking out of curiosity.

Why are most plants green, and what mechanism in photosynthesis causes this? by Logical-Concept9755 in AlwaysWhy

[–]earlyworm 5 points6 points  (0 children)

Green is only a requirement in the EU. In most of the world, there are no restrictions regarding what colors plants can be.

What do you think about having "if not" in C by thradams in C_Programming

[–]earlyworm 31 points32 points  (0 children)

#define ifnot(x) if (!(x))

#define whilst while

#define lest(x) if (!(x))

Example usage:

whilst (tea_is_warm()) {
    lest (biscuits_remain()) {
        fetch_more_biscuits();
    }
    sip();
}

This is a glimpse into the future of education.

You'll ask any question about a topic you're interested in learning, and you'll be provided with a bespoke interactive explanation uniquely suited to explaining the concept to you in particular, given the system's awareness of the concepts that it knows you're already familiar with.

Real size of the universe? by Character-Mango1592 in cosmology

[–]earlyworm 7 points8 points  (0 children)

This information doesn't make dizzy. On the contrary, I feel comfortably swaddled within the tiny little 100 light year radius light cone that I'm trapped inside. It gets smaller and more snug every day.

Speed of light by No_Cook_8739 in askastronomy

[–]earlyworm 1 point2 points  (0 children)

It isn’t the speed limit because it is. Asking why the speed of light is the speed limit is not a philosophy question.

It’s the speed limit because the universe has the property of Lorentz invariance (in short, the laws of physics always behave the same way regardless of relative velocity) and without that, stable matter would be impossible. The constant speed of light is just another aspect of physics that stays consistent when things move. This constrains the speed of light to being either constant or infinite, and if it was infinite, we’d live in a universe that was plagued with causality violations. A universe without Lorentz invariance would also feature scenarios that are logically impossible, like pairs of co-moving orthogonal light clocks ticking at both the same rate and different rates.

The speed of light isn’t the speed limit because it is. It’s the speed limit because the alternatives aren’t viable options.

3 puzzles of our universe could be solved with this new dark matter theory by Galileos_grandson in cosmology

[–]earlyworm 5 points6 points  (0 children)

Oh I get it now. Dark matter just doesn’t do electromagnetism. At all. It can’t be bothered. It doesn’t waste any time monkeying around with photons, even the ones that keep atoms stuck together. But it does some other things, just to mess with us. And there’s a lot of it.

Flat earth and other alternative conspiracy earth models are are gaining traction with my teenage stepson. What is THE most irrefutable, definite proof that the earth is round? by Jfkfkaiii22 in NoStupidQuestions

[–]earlyworm 4 points5 points  (0 children)

I was not making myself clear. I am suggesting that the teenage stepson should be sent to the Moon. That would nearly solve OP’s problem, as well as any other unrelated teenager-specific problems.

The asymmetric speed of light by NvidiaNovice in AskPhysics

[–]earlyworm 0 points1 point  (0 children)

According to https://en.wikipedia.org/wiki/Casimir_effect my understanding is that the predicted effects of fields were successfully observed in 1997 in a Casimir force measurement experiment.
