Trying to get a job, which requires better equipment.

I need a job, to be able to afford the equipment.

Solution: Become the better equipment.

You're welcome for the extreme motivation that you just received. This was thanks to the free trial of my "extreme motivation course". To access "full extreme motivation very hardcore", buy my course for just $999.99.

Damn, the yellow robots from Murder Drones are so attractive, why did i have to watch that series?

Just watched a Tibees video about the possibility of a force like gravity potentially traveling through folded 4D space and affecting something before the light can reach it.

I realize this sort of thing has been thoroughly tested and debunked, but I can't get it out of my head. What if it's some force other than gravity? What if Earth just happens to be folded against some empty bit of space - and what if that were to change?

Like, I've thought about folded spacetime before, but always in the context of traveling between points (like the classic ant-on-paper thought experiment). I never really considered that something could in theory radiate a force (like gravity) in 4+ dimensions.

Maybe you've seen this already, but if you haven't, here's a wonderfully terrifying thought:

Something I've been thinking about is... I often mention that I've been trying to look for more friends for a while, because I don't have any that my mind would qualify as any that I have access to, and I often get two questions, 1) how do I define a friend, and 2) how do I know friends would make me happy.

The first question is a rabbit hole in disguise. Most people, when asked, would list a bunch of benefits, right? Things like "someone I can trust" and "someone who puts me first". But that's the thing. Take the first question for example. Do you not have any enemies you might consider at least honest people? And do you not have friends whom might inspire some skepticism? They're not absolute. So that begs the question, what do I answer to the question of what a friend is? I do in fact have an answer, but it's goes deeper than words, the same words used to answer the question. It defeats itself in ways that swell the question rather than remedy it.

As for the second question, that's where it becomes like anhedonia embodied by words.

A friend is someone who reciprocates tolerable presence.

You don't know friends would make you happy, but they can help you pass the time in less pain.

[–] Rodeo@lemmy.ca 7 points 1 year ago (2 children)

I sure hope friends are better than just tolerable.

Let's go with enjoyable. Tolerable is like the bare minimum for how to behave around other people. Friends are more than the bare minimum.

A friend is someone who reciprocates enjoyable presence.

I'm sure plenty of people would understand it, but I'm struggling with a project at work where I've got an operator giving me bad data, and the project appears unsafe and I need to decide and convince my management if we're going to object to it or not.

[–] HowMany@lemmy.ml 6 points 1 year ago (4 children)

What is the mechanism by which gravity "pulls"? Puzzling me for almost 10 years. I think I've almost got it.

[–] Byter@lemmy.one 8 points 1 year ago* (last edited 1 year ago) (1 children)

There are a lot of analogies but they all fail in some way. I think PBS Spacetime does the best in general, with good graphics to back up the words.

My layman's explanation is probably all stuff you've heard before. Massive objects "warp" spacetime and things that get stuck in those "wells" eventually fall to the bottom due to drag (from a variety of sources).

You've also probably seen the rubber sheet with a bowling ball in the middle used to represent that warping. To visualize that in 3D, I like to imagine a 3D grid of nodes and edges (like a jungle gym of joints and bars) where the whole thing is flexed inward towards a center point. More warped near the center, less warped further out. That kind of conveys the acceleration from gravity felt by things around that center mass.

I'm toying with time-domain audio codecs at comically low bitrates, and wondering why error diffusion is so damn hard.

I'd make a slight change that nobody I personally know would understand or care to try to understand.

If universe is expanding that means further away something is the faster it moves away from you. At some point that will cross the speed of light. This can be thought as an event horizon.

If expansion of the universe is accelerating it means that this event horizon will eventually start to come closer.

Like event horizon of a black hole this horizon will also radiate Hawking radiation, but inwards.

When the inside volume of this event horizon gets small enough, will the mass energy of the Hawking radiation get strong enough to counteract the expansion of the universe and form a stable bubble that wound produce baryonic matter inside the bubble from the massive energy density that gets released from the event horizons grip.

Could this be analog to big bang type event and can the interaction of the bubble with outside universe give us a sensible model of the early inflation.
