Hello Masto-peeps who use screen readers!
I just learned that I need to put alt text on URLs for more accessible PDFs, but -- what should it say?
I am formatting academic citations that include a URL, so all the information about where that link will take you is in the text. I don't want it to read the URL to you and I don't want to just repeat the same information you just heard. What do you find most helpful in this situation?
Pls boost for reach!

Even if earth just gets pulled away from the sun a little we are screwed.
I get what you're saying, but had to laugh at the use of "a little" here. The goldilocks zone in the solar system is roughly the between the orbits of Venus and Mars, and we're almost right in the middle of it, so "a little" is like 150 million km.
I would imagine that the first issue we would experience would be that the moon would be pulled out of Earth's orbit first and then we lose the ocean tides and the stable tilt of the earth. It would probably get worse from there.
Goldilocks zone is basically just where life can survive.
Even if we stay within the Goldilocks zone doesn't mean that most of the species alive today won't go extinct because it fucks up the seasons or the magnetic poles or tilt of the earth, etc.

Right, but I don't get why this thread is full of people talking about collisions. Even if it was moving at the speed of light (it's not) it's still billions of years away.
It would just prove our theory of universe inflation to be incorrect.
I know you can't see this comment but maybe someone else will find it useful
Just like how a siren changes pitch when it's coming from a vehicle passing by due to the Doppler effect, the same thing happens to moving light sources due to relativistic effects.
Usually astronomical objects are redshifting because the universe is expanding and are thus receding away from Earth's frame of reference. Most of them are forever unreachable even if we could travel at the speed of light.
Something blueshifting means it's coming closer from Earth's frame of reference. In some cases, this could result in the galaxy colliding with ours, such as the hypothesized collision between the Andromeda Galaxy and the Milky Way
If it's blue shifting from that distance, then it's likely some advanced technology is moving it in our direction.
There's not many other explanations for that.
Could it potentially be an object orbiting around the cosmic center that just so happens to have an orbital path that crosses us?
I have to admit that astronomy is what caused me to change majors, but that's because I stopped going to class when the lesson was, "This is a terrestrial planet, it's rocky," and my first exam was like, "If it's 5:45pm in Tanzina on October 15th, how many degrees is the moon above the horizon?"
Since the speed something is moving away is dependent on the distance, something billions of light years away is absolutely not going to be moving towards us, regardless of its local orbits.
Let's suppose that for some reason it's completely normal, and it's just simply speeding toward us.
OP says it's billions of light years away. Doesn't that mean that we still have a few billion years?
isnt andromeda gigantic in the night sky but weve got too much light pollution to see it normally?
anyway retvrn to alien
It is gigantic & very luminous but it's also just too far away to be really noticeable - on its own is just on the limit of the best of human eyes if there would be no other star in the sky (very dim, with the visible/luminous core being only about the size of the Moon or smaller - the full galaxy is 5× larger on the sky compared to Moon, but that's not comparable in luminosity).
Disregarding human pollution there are just too many starts from Milfky Way way closer to us.
So blue is moving toward you?
I was always a bit confused with the explanations in high school. But I also got a D in physics so maybe I'm just dumb.
Blue shift, it's moving towards you, the photons are being "compressed" to a higher, bluer frequency. Redshift, the light is being "stretched" to a lower, redder frequency. Both only noticeable at significant fractions of the spped of light, relativistic speed.
Something ominous about the post is that a cosmic object that is moving towards you at a steady rate is consided "blueshifted" in the past tense, it's velocity is steady. If a galaxy is "Blueshifting" in the present tense, then that galzy is somehow accelerating at you, which is impossible unless it's under direct control by an entity, presumably a kardeshev level 3 civilization.
It's not just that, but it is unlikely that any star in our galaxy will collide with any star in Andromeda.
I think it's easy to think of galaxies as individual things, like these nodes in the universe where all the stuff is stored. But galaxies are incredibly vast and incredibly empty.
I love the video this guy did on the subject: youtube.com/watch?v=VsRmyY3Db1…
The part that stuck with me is that if you made the Milky Way the size of the United States, our gigantic sun holding 99.86% of the matter in the solar system would be microscopic -- the size of a red blood cell. And iirc, the planet earth would be all the way down to the size of a virus.

Yep. Space is expanding everywhere at once, but the effect is minuscule at the scales we're used to. And even at galactic scales the "speed" of expansion might seem like a lot to us, but it still isn't enough to overcome the motion of objects. I looked up some rough numbers to give you an idea:
The rate of expansion of space is 73 km/s/Mpc. So for every 3.26 million light-years between you and a distant galaxy, the space between you and that galaxy is expanding by 73 kilometers per second.
Andromeda's blue shift indicates it's headed towards us at 110 km/s. And in my non-expert head I'm thinking that blueshifted light must have already been redshifted by the millions of years traveling through space to reach us. So the galaxy's speed through space towards us when the light was emitted was considerably higher.
Andromeda is 2.5 Million light-years away, btw. So the cumulative distance of space between here and there is expanding at something like 73 km/s/Mpc * 2.5 Mly * 1Mpc/3.26Mly = 57 km/s.
But when talking about relativistic distances and speeds, basic terms regarding time and location don't always make sense.
Milky way and Andromeda are close enough that expansion is too small to overpower gravity
Our local group is racing toward The Great Attractor but will never reach it as expansion is pulling it away faster than we're falling toward it
For example, tomorrow there should be more space between the Sol and Alpha Centauri systems than there was yesterday.
Galaxies are gravitationally bound, they do not expand in the same way as the universe.
It's the doppler effect, but with light instead of sound, and for the same reason.
Thing emits sound/light waves at a constant rate: sound/light waves hit you at a constant rate.
Thing continues to emit the same sound/light at the same rate, but starts to move toward you: sound/light waves hit you at a faster rate, causing the sound/light to turn higher-pitched/bluer.
Thing continues to emit the same sound/light at the same rate, but starts to move away from you: sound/light waves hit you at a slower rate, causing the sound/light to turn lower-pitched/redder.

From my understanding blue and red shifting is mostly related to movement. Like when a firetruck run past you with sirens on, you can hear change in pitch when compared it moving towards you vs away from you.
It's a similar effect with galaxies, red shifting means that after the light was emitted the space between us has increased and the light kind of stretched out to longer wave.
Now anyone with more knowledge on the subject, please correct me.
Now imagine if it did blue shift.

You're missing the point that the universe is expanding uniformly. That means two points acceleration away from each other is dependent on their distance apart. The further they are from each other the faster they accelerate from each other.
So GP is right. We measure red shift and infer distance.

Reminder I am hireable for coding work, and I can be paid in sex toys, cryptocurrency, or sex.
My rates depend on the kinda work being done, but I don't like worrying about things being transactional. Just, if it feels like a good trade, imma take it.
My usual rates are 50 EUR - 80 EUR an hour, for context.
But I reaaaly wanna be dommed by a hot domme, and don't mind doing something simple for you, like reverse engineering a small-ish Linux kernel driver and rewriting it in Rust or smth, if I get dommed enough,,,
Note that I am *slow* at doing things.

I hate AI as much as the next fedizen, but as per the update to this article, the CPU/memory spikes some people experienced were due to a different issue:
Mozilla reached out to me on Aug 14 to clarify. Some users who installed the Firefox 141 update in certain locales did experience performance degradation, but it was caused by a different on-device feature, not Smart Tab Groups which debuted in the update:“After receiving reports of issues that hadn’t come up in our testing [of the new semantic Url matching feature], we reversed the rollout and the performance issues should be resolved. We are working on a fix.”
(this is why links are more useful than screenshots)

@anselmschueler
This is more like integrating AI for the only reason: integrating AI. Imho there is not a real reason for such a feature.
If you are using tab groups you are able to group the tabs by hand - and most of the time you already know a name for your group. Its like taking a sledgehammer to crack a nut.
@soc
Exactly. I am more than willing for every tech feature to be irreparably harmed by association with AI (whether it uses AI or not and only purports to) in an all-encompassing effort to make AI toxic in all its forms (even imaginary ones).
@anselmschueler it's a PR strategy I've been pursuing from the jump and it's been very effective (if you look at any kind of surveys of what people think of AI — they don't want it, they think it tarnishes anything it touches, etc).

The image features a man dressed in a formal suit with a white flower pinned to his lapel, holding a can of WD-40 in his left hand. He is using a red straw to drink from the can, which is unusual as WD-40 is a cleaning product and not meant for consumption. The background includes a statue and a wall with a warm, golden hue. The text at the top of the image reads, "If you can't drink WD-40, then why does it come with a straw?!" This text humorously questions the inclusion of a straw with a product that is not intended to be consumed.
