If light gives up energy due to universal expansion, only red shift is evident. If light gives up energy due to other interactions, many more effects are evident and can be observed. None have been. I was going to give you +1 for that statement, but then I would have had to give you -1 for the rest of your uneducated post. You're still even; which way you go is up to you.

If you feel strongly enough about it to compare the US to NAZI Germany, it may be time to move. Canada's nice this time of year; we just had our first snowfall in Southern Ontario, today ( didn't stick ).

One could take the cynical view that he has found how to make large amounts of money by being controversial. Or you might think that the Canadian Government is too controlling of people's lives. In Canada ( Ontario ) we are required to show a double ( approved ) vaccination passport to dine in restaurants, attend sporting events/concerts, or have a drink in a bar. If I cross into the US and stay longer than 72 hrs, I am required to get tested before entering the US, and again within 72 hrs of re-entry into Canada ( at my own expense for a PCR test ) even if doubly vaccinated, and having had Covid. Things like this would undoubtedly lead to gun shootouts in the US, wouldn't they ? I myself think the Government has every right to be controlling in public health matters, where your illness could affect many others who are unknowingly exposed to you. The Government has every right to control what you DO. They have no right to control what you THINK. And should control what you SAY, only in cases where it can directly affect public health/safety. In case I wasn't clear, I don't agree with his 'politics' on vaccinations/public health measures.

As you probably did for that reply ...

Not to belabor the point, CharonY, but the passages are clearly and accurately quoted, 5 posts back, and 15 hours ago.

I just substituted old people for people who demand others use preferred pronouns. I used similar arguments as have been used to defend the demanding of preferred pronoun use. There is such a thing as age discrimination, you know 😄 . And old people die in greater numbers than the general population 😁 .

I don't see what any of the other issues you feel strongly about, have to do with the fact that you brought up how the social backlash against the professor was just one isolated incident. Then you, again, complained when I gave another example, indicating it isn't an isolated incident. You opened the door; I walked in. Please keep in mind that this is an ideological discussion, and it doesn't change the way either you or I live our lives.. If I, or others< should stress you out, go grab a beer and relax, knowing that I do use people's requested pronouns. Our discussion isn't going to change the world one way or the other.

Less than a quarter of the price of a Mac, and better spec'd. I have fond memories of it also.

You said To which I replied "No it isn't" and provided today's example, with a link. You then said So why would you have brought it up in the first place ???

Oh, I see. Old people are not allowed to voice their view of the world. They are simply angry old men/women who resist change. A young person would say they are almost 'delusional'. How is that for youth privilege ? Again, does a person's subjective world view only count when you agree with it ???

There are plenty of examples of 'social backlash' on university campus. Not all have to do with pronouns or gender association. Here is one from today ... John Cleese pulls out of Cambridge Union event over ‘woke rules’ | John Cleese | The Guardian ( though I'm sure you will claim J Cleese quit, and circumstances/pressures had nothing to do with it 🙂 )

i2 = -1

The term (ic) has to be appended to the t term for calculating the interval length, which has to be a 'distance' in space-time. It does not need to be appended to a space-time diagram, as it will not change the shape of any 'curves' plotted in your space-time diagram. Try it with X and Y on graph paper, then substitute 2X for every X value. The only thing affcted is the spread along the X axis. The difference on a space-time diagram would be that the diagonal ( representing the boundry between spacelike and timelike motion ) has a slope of 1 instead of c .

Like, within the last 2 hours, or just today? Maybe you mean how many have I done since last week? Please clarify. You are perfectly capable of getting onboard the train of thought that Trans people commit suicide in much higher rates, not of their own volition, but due to the external pressures of oppression and bullying. Yet you can't grasp that the professor quit because of those same external pressures, and keep insisting that she quit and was not fired ? Maybe I should have asked "Do you choose to apply root-cause analysis only when it suits your argument ?"

I haven't seen LISP referenced since the 80s either. At that time I also used the Atari ST, and learned Forth on it.

If in a long orbit about each other, any energy loss would be small, as it would be via gravitational waves. On long enough time scales they would eventually merge. IIRC, the limit for electron degeneracy, after which collapse to a neutron star is mandatory, is approx. 2.3 solar masses. While BHs have various collapse points ranging from 4 to 10 solar masses. Depending on which one eventually turns out to be correct, if the lower, then a resulting BH is assured. However, if the limit for BH formation is the upper, 10 solar masses, then two small neutron stars will not necessarily result in a BH.

I learned English in 6 months ( in 1968/9 ). I studied French for 6 years ( Gr 7-Gr12 ) and I still can't carry on a conversation, although I can read it and understand it if spoken slowly enough. I suppose the difference is that I needed to use English every day; French, not so much. Incidentally I still do basic math functions ( +, -, *, / ) in my head, using my native Italian. ( so I guess learning new languages really messed up my brain )

I'm not sure I understand what the problem is. On a regular graph, is there a requirement that X and Y must share the same units ? Or can they simply be related by a constant of proportionality; in this case ... c ?

watch out for Joigus. He says he is a liar, and then, tells you he's lying. Next thing you know, smoke is coming out of your ears.

No, I guess that would undermine my whole argument.

Neutron stars don't have an extended radius around them from which gravitational escape is impossible, like Black Holes do. Unless by 'close' you mean close enough to exert some 'drag' on each other, and lose some energy ( such as via gravitational waves ), there will be no capture or merging. Not sure what you mean by gravity cancelling, but where two neutron stars are close enough for mass to spiral from one to the other, neither will de-collapse to white dwarf. Rather they will lose energy fairly quickly, due to gravitational wave emission, spiral in to each other and, depending on mass, either form a larger neutron star, or a Black Hole.

Yes, I asked Kathleen Stocks 😁 . You've never done root-cause analysis, have you ? I wonder, if the suicide rates among disenfranchised, disgraced, fired, or forced to quit professors is higher than in the general population, are we going to assume it's because they are oppressed, and we should grant them more freedom to say whatever they want, and socially force others to agree with them.

Mind you, these would be definitions of a Physicist ... Objective - properties inherent in the object being observed Subjective - properties perceived by the observer of an object Now I don't deny that everyone has the right to proclaim their subjective view of themselves, and the world around them; If you feel like a 'Ze', you should be able to say so. But the operative word is 'everyone', trans people, gay people, straight people, even MAGA people. Yet society strongly pressures, to the point of ostracization and job loss ( if not law ), people who don't think you are a 'Ze' from voicing their subjective view of the world around them. Do we ALL have that right or not ? Are we only giving that right to people who yell loudest ? Is that the kind of society we want/need ? We are, in effect, taking the right to their subjective opinion from those people who disagree with 'political correctness' ,as applied by the rest of society. All to make up for past wrongs, oppression, and coddling of people with agendas or mental issues. Incidentally, suicide in the general population is regarded as a mental issue. Yet in Trans individuals, suicide is seen as a result of ongoing oppression.

Hey, I didn't realize this discussion was going to be catered.

Do you really expect evidence for this nonsense, Beecee ?
