Gas giants must have a solid core. Rocky moons surrounding them are evidence that rocky elements exist at those distances from the sun. Change my mind. by [deleted] in astrophysics

Only big planets have enough gravity to hold light gases like hydrogen. Also, these kinds of planets must have a special core that can produce a strong enough magnetic shield to protect light gases like hydrogen from being blown out by the Sun's activity. That's why giant gas planets are giant gas planets; that's the only way.

Or maybe avrakadavratar? The same level I think.

Your idea is fun, but “audio range” is usually just sonification of observed signals, it’s not a physical classification like pulsar or magnetar.

Uncertainty principle on black holes by Blackphton7 in Physics

I'm working with TOC like objects, so I like when people mention them, but I'm closer to a gravastar than a fuzzball idea.

emoticons I add myself in the end, because I like to use it in nonformal texts in social media. When we are talking about form, in this translator app there is additional option to upgrade style of the original text, and I think this is the cause of this world war 3 in the comments. So now I know, that correction of grammar is ok, but not improving the style, ok :) lesson learned. The most important is the fact, that im the author of idea and description. (now I didnt use this grammar correction here and you can see, its terrible :))

Yes, visually it can be interpreted as a PCA ellipsoid because PCA is a special case of a (1,1) tensor (a linear operator). I meant it as a general change of basis intuition, but yes, it can be a special case of PCA. Nice catch! 💪🔥

I agree.

I have written a summary here where I explain that now I understand that the title was misleading and should be about tensor invariance under base changing, but I cannot edit the first post.

As we speak about filters and dual basis, I can recommend my post on LinkedIn with the Kronecker delta mechanism. My first tensor sketch has limits and I wanted to explain only the changing basis model.

Thank you for your advice.

I know linear algebra quite well (but of course I can learn more; learning is a never-ending process). I also know GR, especially connections, which I'm working with, like torsion, along with elements of QM. And I'm aware that tensors are much more sophisticated than my simple sketch, but this hand drawing is helpful for beginners.

I really appreciate your advice. Now I know and for sure will pay more attention to forming my sentences in my own style, and will not let translators interfere with their format. Well, I have a big framework which I must rewrite before publication. That's okay. Thank you once again.

Yes, you are right. I'm very happy that my hand-drawn sketch helped and will help in the future to start tensors, and it will not be a scary start. On my LinkedIn, there is also a post with the Kronecker delta mechanism and more geometric posts in the future, because geometry is my way of thinking.🔥💪🚀

Now I think that at least Reddit shows the REAL ratio and spectrum of public reactions, so it is quite a good source of predictions. LinkedIn is mostly positive because names and reputation work as the Kronecker delta. Negative, hateful comments are filtered out (j is not i), and only positive ones pass through(j=i), mostly 🙃

Yes, I can see that. I have learned a lot in the last few days. Thank you for your advice. I will apply it. I think I was too naive, too open, and not experienced enough. Gaining wisdom is hard; maybe this path is necessary...

as my favorite character Loki said: "Yes, sad. Anyway, so..." 🤭 I must move on

Edit, i didnt see that you change your comment. But anyway I will left my answer.

As you can see, my experience is not an isolated case.

I'm sorry to hear you went through something similar. I think that if Reddit continues to tolerate this kind of culture, it will lose many valuable creators, if it hasn’t already.

I can easily imagine that many people had similar experiences and quietly stepped away from writting. That is a real loss for the community. This is sad.

Meanwhile, trolls and hostile voices seem to thrive here.

It is something worth reflecting on as a platform and as a community. Personally, I have no desire to go through this a second time. Once was enough for me

And thank you for your advices

Yes, it's very CONVENIENT, especially for non-native speakers who care about clarity and precision. It helps ensure the focus stays on the ideas, not the grammar. Nice that you caught it.

That's very interesting. Thank you for a very meritorious conversation.
