has anyone asked an AI try take a try at this problem?

2 years ago | Likes 5 Dislikes 4

Sorry you're getting downvoted for asking a question. The answer is that AI can't do that type of thing because it's only able to work with and summarise what we already know. It's not actually intelligent by any real definition of the word.

a well posed question to an AI may not be able to come up with a complete answer to a complex question but it can sometimes point in a direction that people may not have come up with.

If they actually figured it out, you'd be hearing a lot more people than just a Twitter screenshot.

this time i'm sure they got it right

and that response is exactly what's annoying about string theory... lots of good will and trust from the public squandered through decades of people bullshitting their way into grants and tenure.

I'll wait for Sabine Hossenfelder and PBS' Space Time team to weigh in on the papers. I'd love to understand it all in great detail, but sadly I don't.

How they got the data!

Wait.. are they saying that gravity, essentially, only exists at a classical level?

2 years ago | Likes 1 Dislikes 0

I'm just a layman, so bear with my limited knowledge, but as I understand it, this is a proposed competitor to string theory. And to me, the proposed experiment to verify this seems to be impossible to conduct, as it would be impossible to isolate all variables, right? In the same vein, how does one isolate the control unit that the variable weight is measured against? Maybe they've thought it all out, and I'm misunderstanding it, but this seems unprovable.

Shhhhhhhhhhhh, you're going to make them give their grant monies back. Loose lips let the cat out of the bag......

Remember when they thought it would be impossible to verify the existence of gravity waves?

So about as probable as string theory then?

*provable, damn it

You don’t need a control weight, you’re measuring variances for the same object. Checking if it’s 1.000000000000001 kg one day and 0.9999999999999999 the next. I dont know how they make that fine of measurement or what variables need/can be controlled, because I didn’t even stay in a Holiday Inn Express last night.

Walmart has some decent bathroom scales. I got one for my wife. She hated it.

As far as isolating variables, at the level to which one is measuring the fluctuation of spacetime, I'm thinking in the vein of stable materials. How can we be sure that the weight didn't gain mass via a chemical reaction like oxidation? A few molecules could change the result. What about losing mass via decay of unaccounted for radioactive atoms within the material? What about storage environment? Or temperature/atmospheric pressure for that day?

On top of all that, if this theory proposes that gravitational wells of large bodies are what causes the interference pattern, how can we ensure that the measurement device is also not affected by the same effect, leading to what appears to be a similar measurement? Again, I'm just a layperson, and I'm sure someone more intelligent than me has thought this out and accounted for it, I'm just skeptical of the proposed experiment at its face value.

I do, however, like this theory. It makes sense without having to go into complex mathematical models like string theory does. My only skepticism is with the methodology of the experiment, as it seems to me to be somewhat impossible to truly derive a solid conclusion from its results without going into extreme methods bordering on the impossible.

Dude, I think you just need to read the paper they published

Hmm... considering the existence of Oppenheim and Oppenheimer, I say we should pool all our resources to finding the existence of Oppenheimest.

But we still need to figure out how mavity works on it own, right?

But wasn't quantum electrodynamics done back in the 1960s?

2 years ago | Likes 1 Dislikes 0

..... Now, I'm a layman in the field. But isn't gravity a *resultant* force of space/time curving? As in, gravity is caused by mass interacting with said space/time? A VERY bad anology, it's like we're trying to unify shadows with light by trying to math how shadows are a thing on its own without light and something stopping said light to generate those shadows?

flex-time..seems useful since I don't understand it at all..

2 years ago | Likes 8 Dislikes 1

I can explain it to you, it's very simple actually. Flex time is when you have flexible times to start and stop working and can even take days off as long as you work a total of 40h in a week. My last job had that. Hope that helps! Like and subscribe.

I take it George Santos finally gave permission to release his work then? Now he's been kicked out of Congress, he needs to show them what they are missing out on, perhaps?
