I don’t think gravitational waves traveling at the speed of light is the same as the gravitational attraction being apparently felt faster than light travels. Similarly, electric attraction between + and - charges is different from electromagnetic waves being transmitted in the field. It’s not light that is “communicating” that attraction.

I used wave function as a bad form of shorthand for the general properties of the photon, such as the theoretically infinitely extending magnetic and electric fields. Those associated fields stop existing when the photon is absorbed onto a screen. They collapse faster than light can travel. This doesn’t ruin much of modern theories, because there doesn’t seem to be a way to transfer usable information through this phenomenon.
No, gravity is faster than light. If there was this lag, we wouldn’t have stable orbits exactly because of the lag you describe. Wave functions of photons also collapse faster than light when they hit absorbent material.
Cutecity [he/him]@hexbear.netto Science Memes@mander.xyz•vibes-based astrophysicsEnglish16·4 months agoIm not reading on that specifically right now, but I think one problem with dark matter is that it’s not a falsifyable hypothesis and likely never will be. I can make up an explanation over any body of proof of a phenomena and just say that my explanation is due to undetectable things. An alternative theory would be something like stars spinning produce electromagnetic fields which account for the apparent acceleration that’s attributed to gravity caused by an invisible mass. You can measure electromagnetic fields and you can refine models of our sun to try and prove it, and then reach for further discovery. Dark matter feels like a well that’s that. Can’t see it, can’t touch it, can’t prove it doesn’t exist. It should be what remains after we’ve actually tried explanations based on observed phenomenas. That’s just my barely informed take on it.

They also have the extra lobe iirc
Cutecity [he/him]@hexbear.netto World News@lemmy.ml•China Can’t Cut Electric Vehicle Subsidies It Isn’t Paying3·6 months agoCant access the article, here’s a dumb AI summary “The article by David Fickling on Bloomberg Law discusses China’s electric vehicle (EV) subsidy system. Fickling argues that China can’t reduce its EV subsidies because it isn’t actually paying them in full. While the Chinese government provides financial incentives to encourage the growth of the EV industry, much of the support is being delayed or deferred, and in some cases, the payments are not made at all. The article highlights the gap between China’s ambitious EV targets and the practical realities of its financial commitments, pointing out that many EV companies rely on the promise of subsidies, even though the actual funds have often not been disbursed as expected. This reliance on delayed payments could undermine the sustainability of the industry and the broader transition to electric vehicles.”

This proof is partial though. This assumes there is only 1 way of obtaining lead. What if lead appeared from fusion in stars younger than that.

This feels very important. I think it’s a core reflexion on why some means are acceptable once the material conditions have degraded enough. In general, when a fight is just, I tend to reflect twice before condemning alleged “violence”, including light stuff like breaking park benches or lamp posts which is heavily demonized in the media, let alone popular liberation armies around the world.
Isn’t that similar to how Hitler got his last job? Genuine question, I don’t know enough and I don’t understand the jargon enough when researching
Not related to the movies themselves but I remember from the original Spider-Man run in the first 100 issues, Spidey goes to a prison riot and understands the guards are the abusers and supports the formation of the inmates union iirc

The game really opens up if you spend a bit of time learning alternate routes and sequence breaks. Many of them are kind of easy too. Besides all that, I just feel weirdly cozy in the depths or outside in the rain. It’s also a shortish randomizer if you go outside of the vanilla experience with like 100 places to check.
I don’t think you can achieve a spiral orbit in an area with so little friction, mostly devoid of dust and gas, else the earth would be on one of those too…
I was definitely talking about the first scenario, as is mostly everyone else. I know not everyone admits gravity (gravitational attraction) might travel faster than light as in the “sun moving” thought experiment. I’m not confused, I’m discussing like everybody else. You linked an article about gravitational waves which must transmit through some sort of gravitational field and they might transmit at approximately c as predicted in general relativity. What I believe is that gravitational attraction, so the general effect of the field will be felt as if it acts almost instantly, and that does not contradict anything about the waves in that field. Because the waves in that field are not responsible for the attraction. This is similar to how photons do not mediate the magnetic attraction in magnets even though they are electromagnetic waves. The current theories (which you are pulling from) manage to mathematically explain that in our moving sun thought experiment, the gravitational force coming from the sun appears to “update” instantly as if it’s acting from it’s actual position without the lag, because of (to my understanding) the curvature of space-time. So I personally can’t fight that on mathematical grounds because that’s above my understanding. But in the end it doesn’t change much of anything to our discussion, because the force of gravity still updates “as if” it was mostly instantaneous and that’s the standard model. Meanwhile, gravitational waves do travel at c but are kind of unrelated to the continous force. They are merely fluctuations in that force. Please keep poking and challenging me at that, I’m still wrapping my head around it and will need better and better sources while I’m hyper focusing on it until I move on lol
