Leaning in, starting the car, hitting the garage door button, putting stuff in, grabbing ice scraper, begrudgingly pondering why I had to get another car that’s currently in the garage, parked where if my running one was it would not need scraping.
Insecurity. People are afraid of being perceived as weak and don’t have the emotional maturity to work through it. They can’t see that it’s a sign of confidence and strength to be able to do so.
Suits. It’s insanely unrealistic, full of nonsense drama for no reason, and just has some of the most insane bullshit. But God damn was it a fun show to watch.
Me being able to teleport would prove that FTL is possible so I think I’d have to take it for that alone. Invisibility in comparison is tricky but very grounded in existing physics.
To light, there’s no difference in those times, as I understand. A light particle doesn’t experience traveling at all. From its own perspective, it exists where it is created, then immediately where it is absorbed, in the same instance. So you could say it doesn’t experience time at all. All of its energy exists in its velocity, and none of it in its movement through time.
Don’t ask me to prove or explain this, because I don’t remember where I heard it or if I even remember it correctly. 😅
Actually light does experience time in its own frame of reference. For somebody observing(us in this example) the light or any object that moves at the speed of light in vacuum, it would seem that object is not experiencing time at all, that is, if there was clock on the object and we tried to measure the time that clock reads, it would give the same number as the result of the reading irrespective of when or where we measure it in our frame of reference.
It was my understanding that light does not experience time.
And yes it does experience time from our dimension because the speed of light is finite, making the lifetime of a photon as observed from a different frame of reference, non-zero.
I think the point I was trying to make was that the lifetime of the photon is nonzero to us, from our perspective, but zero to the photon, from its perspective. All of its energy is in its velocity.
Remember in Interstellar when they slingshot around the black hole and it cost them like 80 years or whatever? The time around them went by faster as a result. Well a photon going at c would see time around it going by at max time speed as well, so it would arrive at its destination immediately after it departed. (From its perspective.)
By what you’re saying, it sounds like you’re confirming what I said, just in a different way. A photon experiences time, but in its own frame of reference, the time experienced is zero. From its perspective, the time it takes to travel from one destination to the next, is zero. Just like the clock following it would show, from our perspective. Or am I misunderstanding?
First of all, talking about a photon’s experience is weird because when moving at the the speed of light, the transformation equations associated with changing the frame of reference start having infinities appearing within them which makes it impossible to mathematically define things like time elapsed or distance travelled.
Secondly it is a little confusing to talk about of frames of reference but I will try my best to explain.
Assume there are two balls(A and B) in an empty region of spacing moving away from each other at speed of 1m/s. Since there are refrences in the background, we have no idea of both the balls are moving or ball A is the only one moving or ball B is the only one moving. From ball A’s perspective, it would seem like ball B is moving away from it while it is stationary. Vice versa for ball B which thinks A is moving while it is stationary. Now let us say that the balls have a way to measure the time elapsed and distance travelled. Now when ball A sees that 10 seconds have passed and that ball B has travelled 10m. To verify this it measures the reading shown by ball B. To its surprise it finds out the reading from B’s instruments show that only 8 seconds have and that B travelled only 8m. This is the time dialation and length contraction that happens in special relativity. Till now everything is fine but interesting things start to happen when you switch perspectives. In the frame of reference of B, it measures that 10 seconds has passed and that A has moved 10m in that duration. When it tries to verify these measurements from A’s instruments, it finds out that they show that only 8sec have passed and that A has only travelled 8m. Now we are in trouble as these measurements seem incompatible. Not only are the instruments not agreeing with each, other, the instruments don’t even agree with themselves depending on the frame. This is eventually resolved by the realisation that the order of events is not the same for all frames. In A’s, frame, it seems to B that started measuring late by 2s while from B’s frame it seems A started measurements later. Adding this 2 second delay in both frames solves all the measurement inconsistency issues.(The numbers used are random. If you actually calculate the difference in measurements coming from a relative velocity of 1m/s, the differences will be exceeding small)
Now that a basic understanding is out of the way, let us discuss the case of the photon. From our frame of reference, the photon is moving at the speed of light, we can measure with our instruments for how long the photon moved and what was the distance it moved but when we measure using the photon’s instruments we see that the clock always shows the same time and no time has lapsed. From the photon’s frame, it seems like it is stationary and everything else is moving at the speed of(which is obviously not true. Weird things happen when we try talk of moving at the speed of light beacuse of the infinities I aluded to before) and so while it clock is ticking, the clocks of the world around it seem stopped. So in conclusion while it valid to say that photons experience no time, it is only because we can’t go to the photon’s frame of reference because physics and math fail us that point.
You’re wayyy over complicating it, invisibility is just a matter of taking the light that hits you, bending it around you and putting it back in place. We can already do this on a small scale with fixed stationary setups.
Even simpler is just a very accurate and fast camera/display system that records and displays the background onto itself.
Repetitive meme posts can get annoying, and mods should intervene in some cases, but I’d prefer if the rules were more open. It’s hard to determine what is “low effort” and “thought-provoking”, and Lemmy is small so further limiting content isn’t that productive
I think people using this community are looking for something similar to AskReddit, and it’s totally ok if you want to be different from that since the Fediverse allows for more communities to be made.
Personally, (and you don’t need to run the community like this), I’m looking for a community for open-ended and discussion provoking questions, not necessarily thought-provoking questions. The stick one was fun and lead to fun discussion
The most fun part of the early internet was the feeling that it was the Wild West. Lawlessness and fun. Obviously, rules are needed to keep things under control, but I agree that erring on the side of having fun isn’t a bad thing. It’s more inclusive and it lets people express themselves.
One of my favorite things to see on Lemmy is people who lurked on Reddit but feel free to talk here. Being too heavy-handed with rules might discourage those people from contributing.
Both should be welcome. Especially with the current state of Lemmy (low user base), over moderation can be a real thing.
More narrowly tailored communities have narrower appeal and Q&A communities function off of their number of users.
This is one reason why on Reddit r/AskReddit (44M) has more users than r/AskMen (5.8M). And why r/AskMen has more users than r/AskMenOverThirty (458K).
I sort of agree, mainly with the lower population of Lemmy concern, albeit I’ve also seen other questions that, while not low effort necessarily, have made me wonder, “Wouldn’t this perhaps be better in a more specific community, or in a different style, like NoStupidQuestions?”
However, low population, not a moderator, so the mixed thoughts have left me refraining from asking or saying anything as I kinda think we already have an abundance of communities sparsely populated as-is and I’m not into backseat moderating. Still, the thoughts have been there and this thread’s given a nice opportunity to voice them.
I’ve also seen other questions that, while not low effort necessarily, have made me wonder, “Wouldn’t this perhaps be better in a more specific community, or in a different style, like NoStupidQuestions?”
Yea I’ve seen a few of those too. Questions that are too specific to a particular app/program or a specific personal problem. Those don’t really belong here
"How do I do X on program Y" (bad) vs. “What’s your favourite program that does Z” (good)
Wouldn't the charter not be more appropriate for a "DiscussOnLemmy" group? And leave "AskLemmy" for proper, answerable questions? That mistake was made on reddit before.
At this point there should probably be a generic “just ask random questions for other Lemmy users” community to direct those people to. People don’t seem to get that this one is similar to AskReddit in purpose, but Lemmy is small so there’s no immediately obvious general communities.
Well, you got what you asked for. As one is not allowed to ask real questions here, you get the "thought provoking questions" you wanted. No sympathy or pity from my side for wasting a good community name for a socio-psychological experiment.
Look at the charter. This group is not for asking real questions, as in "Does anyone know..." or "How do I...", but for "though provoking" discussion starters. A bit like r/showerthoughts on reddit was. For that, a name like "asklemmy" is wasted.
edit: meant in general, not just amazon, added other
Any site you go with, I would make sure to triple check labels, reviews, warranty of laptop and the one offered by website.
Maybe more expensive, but warranty for a year, Newegg/Amazon/other also has some, and the one you mentioned.
Random search brought up Newegg:

I’ve thought of using Amazon, but it’s not really a thing in my country, I don’t even know if they ship here, furthermore I’ve never shopped on Amazon before, so I have no idea how it works…
(I just checked, Amazon does not deliver to my country and Newegg is an American thing afaik)
And even further more, I don’t know which are the “trusted” replacement battery manufacturers
