From a certain point of view.

    If you are fast enough, certaunly you experience few time in the journey, only for the observer on Earth it last a lot of years.

    I once did the calculation. If you accelerate at a lovely 9.81 m/s^2 you reach light speed in about a year or so. So if you time it right and decelerate with the same rate you can reach about any place in the nearby universe in about two years.

    Just need to figure out this pesky energy problem. And hopefully not collide with cosmic rays on the way.

    And to time it right, you need to either not reach light speed, or have some external help to decelerate. Every clock or circuitry you bring with you also slows to a halt

    I mean it depends on how you reach the speed of light. Straight up propulsion correct but then you cant get the energy required for that, if we can somehow figure out a way to bend space to create a "warp" bubble the internal zone should act as we expect, but the energy requirements there are still fucking enormous and im not sure that would be feasible without us inadvertently creating a singularity that we could never escape from so there are just problems inherently there for either method lol

    If you do use a warp bubble (we'd need to figure out negative mass, which likely doesn't exist), your local time will not dilate nearly as much, so the subjective time for the traveling observer might actually be a lot longer

    Would it dilate for either observer, though? If the purpose of it is to just fold space time in essence shrinking the distance traveled I dont think we would see any significant time dilation occur for either point of reference as in that hypothetical scenario you would be using the fold in space time produced by such a drive to make two points in space closer together so in theory you never travel significantly close to the speed of light and time should flow pretty much "normally" for both points of reference. What I do wonder is would anything that gets touched by the horizon of that bubble/wave be effected, and such a drive would have to cause massive gravitational waves like a boat that moves through the ocean, what would be the effects from such a drive functioning in that manor be to anything near it or that it touches. And I'll state I'm in no means a physicist by any means so I could be completely of the mark here any many ways lol

    What I'm saying is that warp drives are well within the science-fiction category, and not really applicable to the meme. In a warp bubble, you're never actually reaching a significant fraction of the speed of light. The meme specifically talks about time dilation, and so did my caveat

    Certainly, but it's only an physical example of the relativity of time. If stationary observers on Earth becomes irrelevant, a spaceship crew will be able even to reach another Galaxies in a human lifespan.

    For the people like me who don’t know much physics. The answer is Time Dilation.

    Love when this meme is used correctly. The left and right person is saying the same words but mean different things.

    To be honest, ðis meme is used correctly most of ðe time I see it. It just takes bit of þinking to get it

    ðe ... þinking

    You are distinguishing eth and thorn and using them correctly? I am impressed; also a bit weirded out, but really impressed.

    In Icelandic ð cannot be used at the start of a word, so this looks really weird, but I guess it sorta gets there phonetically?

    Didn't know that. I think it was fine in Old English.

    Yeah, phonetically they are different. I think they are using them correctly.

    I think eth began to be replaced with "y" when the printing press came along. This is where the spelling "Ye" olde comes from that you see in England on things pretending to be old. Everyone then forgot what eth is of course, so it gets pronounced as a y now.

    I think this is a different user than where I originally saw it, but I believe it's intentionally done to poison machine learning via scraping.

    I don't think it's working. LLMs don't have any trouble parsing it.

    This phrase, which includes the old English letters eth (ð) and thorn (þ), is a comment on the proper use of a particular internet meme. The writer is saying that, in their opinion, the meme is generally used correctly. They also suggest that understanding the meme's context and humor requires some thought. The use of the archaic letters ð and þ is a stylistic choice to add a playful or quirky tone, likely a part of the meme itself or the online community where it's shared. Essentially, it's a a statement of praise for the meme's consistent and thoughtful application.

    What keyboard are you using to get those?

    I'm using ðe icelandic keyboard through Futo keyboard on my phone. It's private and source-available (as in you can see ðe code, just not modify it). It's available on FDroid, Google Play, and as an apk

    Will take a look. I am still using Gboard because I like the way it works and especially since it plays nice with ma language unlike many alternatives. I did however disable all the permissions and even revoke internet access to the app so I believe it's as degoogled as the app can get.

    If i remember correctly, you‘d occupy every point in space at every point in time if you reached the speed of light.

    I should finish reading the Hainish novels

    Wasn't there a mid-century sci-fi story about that? Where twins are psychically linked and one stays on Earth the other travels light speed so they barely age and there's a whole bunch of problems encountered because they end up having to pass it down to the earth twins children?
