I will start by agreeing that usage of "war" seems weired. Although scientific drama in fundamental physics is not uncommon but a word like "debate" would be more appropriate. I don't like your usage of word "Inshallah" as a mock up of the idea that something will never happen. Because it is a complete opposite meaning of when you suppose to use it. It is usually overused by arab moms (I know that people tends to mea…

Please see my other comment; I used "inshallah" wrongly.

No problem, happens to the best of us. No hard feelings.

That is part of the original etymology of the word. [1] > late Old English wyrre, werre "large-scale military conflict," from Old North French werre "war" (Old French guerre "difficulty, dispute; hostility; fight, combat, war;" Modern French guerre), Note the old French part including difficulty dispute, hostility and fight. [1] https://www.etymonline.com/word/war

Wow, words changing meaning over time. Imagine that. The internet would lead me to believe that’s something horrific that must not be allowed.

The OP doesn't like the meaning of the word "war" changing from a definition they believe to be correct. My example shows that the meaning of words is defined by usage and that usage changes over time. This is especially ironic in this particular case because the meaning that the OP didn't like is one which was actually part of the original etymology of the word.

Your response needlessly called out Arabic for using too much “Allah”. English overuses it the same amount, given that Allah is their word for God.

> English overuses it the same amount Not even close! I only have experience in the Gulf but they use "allah" words all the time! "Alhamdulillah" (thank god) is pretty much part of the standard greeting (Pretty much just two people rapid firing a list of phrases at each other simultaneously "peace be with you / and also peace with you / how are you / thank god / how's the family / thank god") and a frequent response…

> "Alhamdulillah" (thank god) is pretty much part of the standard greeting

Same goes with English! When parting ways, people commonly say "bye" or "goodbye" which is an evolution of "Godbye" - a contraction of "God be with ye"

That means there's no Gravity before The BigBang, right ?

the big bang is a singularity; we can't ever experimentally learn anything about what came before it. that doesn't mean there was no time before the big bang, or no gravity, or that there wasn't another universe just like ours. But due to the singularity, for the sake of convenience, we simply _say_ that those things came into existence at the big bang. cite: https://www.hawking.org.uk/in-words/lectures/the-beginning…

It was pointed out that in American English we overuse "war". I pointed out a language that overuses a different word. I imagine most languages have a bunch of phrases involving an overused word. My point was that this phenomenon isn't unique to American English. Your response is that English also overuses another word. I don't understand the point you are trying to make.

Your response needlessly called out Arabic for using too much “Allah”. English overuses it the same amount, given that Allah is their word for God.

>English overuses it the same amount,

Nah, even a short interaction with a muslim would key you into the fact that they use allah based phrases way more often than the typical american or christian.

So the main issue here is how people were presenting it, in Quantum field theory, as stated by other people, each force is associated with a field and has at least one force carrier, the exact number is linked to the specifics of the mathematical framework underlying it To that extent you can build 3 fundamental forces, electro magnetic, weak (that are called together electroweak) and the strong force. You have an ex…

> neutrinos have mass and this in itself is a problem because the Higgs mechanism doesn't provide mass to them ... The Higgs mechanism doesn't provide all mass, even of the things that it provides mass for. They each have a "bare" mass, that is, a mass without any Higgs interactions. They just have a much greater mass because of the Higgs interaction. (And maybe that's why neutrinos have so little mass...)

Uuuuh... No...

The W Z have only mass from the Higgs and nothing else for example.

But to answer your point completely here is an answer which is in the two following links making the point for the Dirac fields

I had a photoshoot scheduled with a young Somali man. He was late by over an hour, and I had another shoot after so I had to cancel. I rescheduled and told him if he was late for the next shoot I wouldn’t be rescheduling again. He said he wouldn’t be…inshallah. I know it’s part of their language but just as with your cab example it can be a bit annoying as an outsider, as it feels like they’re passing off responsibil…

> they’re passing off responsibility On the other hand. For example in Kiswahili "Shauri ya Mungo" (God's business). Perhaps not exactly the same, but sufficiently similar to be interesting: that some things are in fact beyond human capability and comprehension has largely disappeared from the English language (or any language from predominately secular countries).

> that some things are in fact beyond human capability and comprehension has largely disappeared from the English language (or any language from predominately secular countries

It's still common in insurances agreements or other contracts that have to consider force majeure - natural disasters and other phenomena fall under the blanket term "Acts of God".

Also, plenty of "secular" curses/exclamations have religious connotations (because it was taboo, and cursing and the taboo are inextricably linked). "Geez", "Gazooks" (God's hooks), etc.

You seem to be frequently flame posting about America. Are you going to be okay?

I think I'm getting an anxiety disorder here seeing as close to 50% of Americans are seemingly OK with Trump, Vance and Elon becoming their new overlords. Seriously.

Normal to be nervous when the stakes are high. One thing that history has taught me is that disaster is always an option lol

I last took a physics course when Pluto was a planet, so excuse my possibly outdated question, but isn't the detection of gravitational waves proof of gravity being a force? I follow a few educators/communicators in this field and I have a feeling they're using this "gravity isn't really a force" to bridge the gap between their deep understanding and us mortals that don't poses the language / understanding to get the…

Fwiw gravitational waves were predicted by Einstein himself (Einstein, Albert, Ueber Gravitationswellen, 1918) as a consequence of general relativity. The core idea is that when you move a mass, its contribution to the spacetime geometry changes, but the effects of the change of the geometry doesn't apply instantaneously to all the universe but instead the change propagates at the speed of light. So that explains why…
