I can see multiple uses for the tech. Unfortunately, many are a but dystopian, but some are legitimately useful.

It was the initial description used in my 1st year physics degree course. Not sure if it has an explicit name. We also jumped fairly quickly from there to the maths.
Basically space time can stretch infinitely, and flows towards mass. Anything on that spacetime is drawn along. It’s functionally identical to a standard force. Straight lines twist into spacetime spirals (aka orbits etc).
Physics has lots of interesting mental models for different things. Unfortunately, most are flawed, so dont lean on tgem too hard. What actually happens is way beyond what our monkey brains can interpret. The best we can do if follow the maths, and try and fit something to the end result.
It’s worth noting that spacetime isn’t static. Space “flows” into mass. It’s akin to a treadmill, you need to constantly move “upwards” to stay in place.
This is also the reason that uniform gravity, and acceleration are identical. With acceleration, the “ground” is constantly moving upwards into new space, pushing you along. With gravity, space is constantly moving down through the floor, trying to push you into the floor. It’s functionally the same thing.
Various events around the universe occur on human timescales. If time stopped for use, we would effectively skip ahead on the view of them.
I actually think we could reliably catch 1 second time stops. Scientists monitor various pulsars. They spin multiple times a second, throwing off radio wave pulses. If all of them suddenly went out of sync with our clocks, it would definitely be noticed. It might take several, however, to prove it wasn’t a weird hardware glitch.
Even if you don’t use it as a password manager, bitwarden has an excellent pass phrase generator. The only annoyance is when I run into maximum password lengths at times.
The issue is if you are a) targeted, and b)involved in multiple breaches. If they can get the pattern, they potentially get everything.
Is it worth it? That depends. Are you willing to risk it NOT being worth it to a random guy in Africa earning a few $ a day?
I tend to prefer pass phrases, they are a lot easier to type and speak, if required. Mine regularly blow past 20 characters.
As for salting, that only defends against rainbow table attacks. The salt needs to be stored along with the hash. That is find for most accounts, but once you’re in banking territory, that’s a bad bet.
You also can’t assume you have no vulnerabilities. If someone gets your database, you can’t defend against brute force attacks.
Lastly, if you are doing passwords properly, you shouldn’t care much about length. There are a few dos attacks to worry about, but a 512 char limit will stop those, and not limit any sane password.
Caps are a lot easier and cheaper to fix than you might expect.
It can be revived!
Exposure can cause similar effects. However, the act of heating the plastic to the temperatures needed to melt it and defirming it also damages the structure. It’s particularly obvious with pla, but all plastics suffer from it, to an extent.
Repeating plastics tends to damage them on a chemical level. The polymer chains break and shorten. This ends with the plastic being more brittle. Since 3d printed parts have already been remelted once, they have even more degradation than injection moulded parts.
I believe the recommended amount of recycled plastic is around 30% for PLA. Any more and the parts lose significant strength.
I personally would prefer us to accept that plastics aren’t really recyclable. It’s better to move towards renewable plastics like PLA, and treat the waste as biomass (either composted or burnt for energy.
Unfortunately, it’s not a useful one. While we know approximately where it is, we don’t know how deep the gravity well is. That gravity well slows the passage of time, just like the earth does. Without an exact mass, and mass density, we can’t calculate the correction factor.
It’s not too bad. Relativity says that no frame of reference is special.
On earth, a second looks like a second, but a second on the moon looks too quick.
On the moon, the second looks like a second, but a second on earth looks too slow.
Both are actually correct. The simplest solution is to declare 1 to be the base reference. In this case, the earth second. Any lunar colonies will just have to accept that their second is slightly longer than they think it should be.
If it helps, the difference is tiny. A second is 6.5x10^-10 seconds longer. This works out to 56 microseconds per 24 hours. It won’t affect much for a long time. About the only thing affected would be a lunar GPS.
I’ve got a similar battery bank. It’ll turn 4 hours of capability into 12, with no issues.
Mine is a veektomx MAX65W. 20,000mah.
Just be aware of capacities. The limit is either 100Wh or 160Wh depending on the airline. That works out at 27,000mah or 43,250mah respectively. Most power banks are below this, but not all.
Depressingly, that’s around 2x the cost/Tb.
Depends how it’s done.
Full generative images would definitely start creating a copying error type problem.
However it’s not quite that simple. An AI system can be used to distort an image. The derivatives force the learning AI to notice different things. This can vastly extend the pool of data to learn from, and so improve the end AI.
Adobe obviously decided that the copying errors were worth the extended datasets.
One of the key thing that LLMs lack is a knowledge layer. In many ways, modern LLMs are hyper advanced predictive text. Don’t get me wrong, what they produce is awesome and can be extremely useful, but it’s still fundamentally limited.
Ultimately, a useful AI will need some level of understanding. It will need to be able to switch between casual chatter, and information delivery. It will need to be able to crosscheck its own conclusions before delivering them. There are groups working on this, but they are quite a bit behind LLMs. When they catch up, and the 2 can be linked/combined then things will get VERY interesting!
It seems to allow it, in a sense. The errors are also left on the transmission end. By transmitting them normally, the 2 signals can be combined to recreate the data. Something is shared, at some point.
It’s definitely a “we’re not sure what’s actually going on” type situation though. Either both ends are drawing on some (otherwise) hidden data layer, or FTL transmission is allowed, so long as no information flows (information as defined by quantum mechanics). It just turns out that weird entanglement based systems are the only ones (we’ve found so far) able to send infomationless transmissions.
Both solutions would give deeper insights into reality, and its underpinnings. Unfortunately, we’ve not actually teased out which is happening.
My gut feeling is that the speed of light is a side effect of a fixed/stable causality across all rest frames. Hidden information seems to be a lot more cumbersome.
The universe seems to be keyed to disallow time travel. The speed of light limit, in relativity, is sat exactly at the limit where time travel would become possible. Conversely, quantum mechanics does allow for FTP transmission. What it doesn’t allow is information to flow along those links. It’s hit with a 0.5 error rate, which completely blocks FTP communication.
General relativity does allow for a few time travel options. However, these are sat well off in the sticks, where quantum relativity would dominate. Since we don’t have such a theory yet, our predictions are likely wrong. Even within these theories, a time machine would require a “closed timelike curve”. These can, in theory be made using several rapidly rotating black holes. Any ship traversing it, would never be able to leave before the time machine was built.
Basically, time travel is almost certainly blocked by our laws of physics. Any loopholes would be limited to the lifetime of the “machine” and would require stellar level engineering for even a few seconds of travel.
I’ve played it more recently, encountered 1 noticeable bug on my entire play though. They’ve turned it into an impressive, well polished game now.
Of course not, that would be immoral. They’ll track trollies and baskets, then tag it to the till and your loyalty card. It would be a lot more consistent, and harder to dodge.
