  • When will we return to that "inferior" thinking of respect for a truly amazing creator who has made all things?

    Hopefully never.

  • @karl Thanks for the input.

    From the abstract I think its the old Lorentz transformation in disguise - but I'm not sure. I would have to see the proposed equations and explanation.

    "...he requirement of invariance is removed..." would brake a very essential rule - and I don't think thats a good idea in this case (it would mean that there is a special frame of reference, braking relativity of motion).

    To read the whole article would be interesting, but I don't have access to this journal - if you can download the article, maybe you can give me a copy (if so, please PM me ;-)

    @v10tdi Yes, it is possible but would need several books to pack all the information of the equations into it - thats how you learn/understand the equations.

  • I am pretty sure all this does not belong to this topic.

    In this topic there is no God, period. Consider this as axiom.

    LOL…an axiom …really? That would be contradicting the controversial argument(s) earlier in this thread of whether Einstein was basing his theories off religious influence or not. I think most of @Sph1nxster’s argument is appropriate with this discussion.

  • @Psyco: Regarding transformations compatible with the relativity theory: Have a look at this interesting article.

  • @Sage is it possible to express the Standard Model formula in words?

  • @soundgh2 It's so funny that you say that, because I remember now that in my Planetary Geology class in astrophysics that the teacher said on the first day that everything we would learn in the class would be invalidated in ten years. And he was right.

    @igorek7 I assume you didn't really mean that our universe is only 1 kpc (1,000 parsecs), since you would not even leave our Milky Way galaxy by traveling only 1kpc.

    You can assume that, and the math would be important work if you could do it. When I was studying astronomy, the best measurements were one milliarcsecond of parallax. I m.a.s. is of course far short of 1 kpc. Using some very sophisticated measuring techniques, we can extend that outwards a bit. The methods of measurement are laid out in the link I posted, and you can always submit a correction to the Wikipedia. Update the data BEFORE you leave the MWG or we won't get it in time.

  • generation has now grown up believing that God does not exist, period, the world and the universe as we know it was created by some mistake of an explosion, and science can answer everything. Dangerous ideas built upon one theory after another and not waiting for facts to be established leads to destruction

    Humans from days gone by had an appreciation that they were only Human, they had limitations in what they could answer, but ultimately they appreciated the existence of God and his power. I'm not saying that all people bowed the knee and believed in God, but generally people respected at least the idea of God. How far we have fallen, when somebody tries to bring God into the conversation it is immediately discounted as Religious babble, then closely followed by "they don't know what they are talking about anyway..... scoff scoff o how enlightened i am"

  • The danger with Modern Science is the way it is perceived.

    Asking why, why, why is a healthy process. It allows people to think for themselves, and in many cases answers can be found.

    Danger creeps in when theories are presented in such a fashion as being absolute certainties. When this occurs the general public are quick to believe and certainly any shred of evidence that may disprove the existence of God is readily snapped up by the media. In a short space of time, theories like the Big Bang have become street terminology and the vast majority of people, who do not do any research into life beyond their own existence, believe it. Why? Human's like the idea of things fitting into models, it helps them to cope with the insecurities of life. Human's are also generally quite lazy, we like to accept whatever is going so long as everyone else believes it.

    Now the problem that we have is that theories like the Big Bang are readily accepted and yet the scientific community is rejecting it as it does not fit. So what damage has this created? Is this not just a simple exercise of finding the truth? Who exactly is hurt through this process?

    A generation has now grown up believing that God does not exist, period, the world and the universe as we know it was created by some mistake of an explosion, and science can answer everything. Dangerous ideas built upon one theory after another and not waiting for facts to be established leads to destruction.

    References on this topic have been made to Human's way of thinking from many years ago. Explaining the likes of thunder away as an act of God as being somehow inferior thinking, and my o my how we have evolved since then. Really? You think things are clearer now? Do we really believe that when we look up at the stars at night we can answer all the questions there are to ask? Scientists can't even agree if the Earth is moving or not, in fact both models can be used for the projection of satellites.

    God has created a universe full of majesty and beauty, one that can leave a person breathless at how amazing and truly intricate it is. Designed by a loving father who wants us to ask why He made it, not how it was made. Now when we gaze upon the beauty of the heavens, we argue about how it works and ultimately every argument is replaced by the next one that pushes God further and further away from the center of it. When will we return to that "inferior" thinking of respect for a truly amazing creator who has made all things?

  • @brianluce The are important relativistic corrections to the Kepler's "laws", which have to be applied, for example, in order to describe pulsars (a type of the binary stars). This is because these very compact objects may not be adequately described by Newtonian gravity. Observations of some of the binary pulsars, such as PSR 1923+16, indicate that their orbit about a secondary companion precesses considerably, in violation of Kepler's first law, and also indicates that the pulsar is slowly spiraling into its companion, seemingly in violation of the law of conservation of energy. A relativistic description of this pulsar's orbit (and of various other binary systems) is required to account for these effects.

    This is a thing about the nature, nothing is really a universal law, "laws" are correct only within a certain boundary conditions. Another example is the infamous Big Bang, a singular region in space-time out of which our universe was born, which is a point where the density and curvature of spacetime become infinite, and our equations (gravity described by Einstein's general relativity, and other fields described by the Standard Model of particle physics) cease to make sense.

    @DrDave

    If the observable universe is 1,000 parsecs, and you shrink a parsec down to half size, the observable universe will be 2,000 parsecs.

    I assume you didn't really mean that our universe is only 1 kpc (1,000 parsecs), since you would not even leave our Milky Way galaxy by traveling only 1kpc. The Solar system is about 8 kpc away from the Galaxy center. One can play with the numbers here to estimate our space-time uncertainties (for example, change Ho from 71 to 50 or 100, or hit Open, Flat, General models of the universe expansion): http://www.astro.ucla.edu/~wright/CosmoCalc.html

    My point was actually the following. While in appearance many cosmological theories are to be purely unverifiable speculations, the confronting tests may come from various global- (astronomical observations) and local- (general and particle physics experiments) data sets.

  • What are Keppler's Laws then? Guidelines, speculation? Conjecture? Fancy?

  • Reality is complicated

    Scientists try

  • @soundgh2 Sounds like that your lecturer doesn't like his job ;-)

    But he is right about string theory :-P

  • @svart I don't quite agree, makeing science the same as a religion. A lot of people like to do that, but that are normally the ones that don't really understand what they are talking about.

    Religion = shut up and believe what you were told! Science = ask nature if your ideas are right.

    But I do agree that money and ego is quite a problem in the academic realm - thats why I turned my back to the universitys - you run with the mob or you don't get a job/money/... (my physics professor was working in the math departement because his ideas are not fancy enough for the physics department).

    (I didn't miss the sarcasm - its just some times to close to the truth to be funny.)

    And the reason why I'm bitching on quantum mechanics is exactly because (as it has no real foundation) we were told to learn it as it is written in the bocks and shut up. Asking "why" or "how" things work were considered as unscientific even by nobel price winners! But as far as I know, things are changing - very slowly - and now even very popular physicists start to think about alternatives to the "orthodox" version.

  • As an Astrophysics graduate and there in the middle of string theorys birth etc yawn - as my lecturer said on the first day of Uni - everything youve learned is bollocks everything im going to teach ou is bollocks - ok lets begin

  • @karl

    How can the universe and everything we "see" be so regular without any pattern underlying it? And don't forget, that quantum mechanics can be completed to an absolut deterministic theory! (Bohmian mechanics)

    The speed of light is not the important part, its the transformations that can be derived from the idea. The Lorentz transformations have to be applied, otherwise we get the incorrect results....so, big deal? Yes, because there are only two transformations that satisfy the symmetries of space and time. The Galilei transformations or the Lorentz transformations. Its quite interesting what we learn about our universe from the simple experimental result, that the speed of light is (more) constant (than not). And thats something that goes beyond a simple model or a theory.

    Its the same with the Bell inequality. Its derived only using simple statistics, yet by doing the experiment it clearly shows if our universe is of "type A" or "type B" - there are no shades inbetween. So, in this cases we get definit answers - something that is very rare, I have to admit.

    Every theory should formulate "first principles", the base (a bit like the axioms in math) the rest of the theory can be derived from. The best example is the theory of general relativity - its one of the most beautyfull ideas ever. On the other hand is (orthodox/textbook) quantum mechanics and all theorys that built on it - its a cooking recipe, nothing else. There are atempts to get a real physical foundation into quantum mechanics, e.g. Bohmian mechanics, many worlds (its not as stupid as one things at first glance),... but none looks better than the others. And here I think lies the core of theoretical physics - its not only about models or theorys and there is more to it than only trying to mimic some experimental results.

    By the way, I don't think there is dark matter - its was invented as a placeholder to apply an old theory to new observations. The physicists "inventing" dark matter were stating this fact explicit in there publications. Idiots made this NEVER observable thing more real than it was ever intended to be. I think the problem here is, that dark matter just sounds very cool ;-)

    One thing to keep in mind:

    Math is a product of our brain -> our brain is a physical system following the same "rules" as the universe (as it is part of the universe) -> Math is a product of this "rules" -> thats why (part of) the universe can be described so well with Math. What we call logic seems to be itselfe an important property of our universe. If it would be totally different, we would have a really hard time describing even the simplest things (but thats ofcourse no proof of that idea).

  • @p4inkiller yes, just yes! I see sarcasm isn't necessarily easy to understand over the internet so I'll explain.



    We humans tend to think of ourselves as special and tend to believe our own theories. Early humans didn't understand thunder/lightning but knew that other humans could make such noise so therefor there must be a "being" that is like humans that makes these noises, and we'll call him God. From then on, God was the explanation for everything that humans didn't understand. Bad weather? god did it. Disease? God did it. etc.

    With the invention of science, we start to realize that there are real, observable, causes for things we don't understand and we reveal that the world works the same no matter how small or large you look. Everything is made of the same atomic soup and therefor everything must work the exact same way once you get down to the smallest level. It doesn't mean that we can't/won't stop looking, but it means that when people can't understand something, they invoke the God principle, only this time they call it theory. Oh, you can't explain how gravity works? Then we'll create a theory that fits! Someone else comes along and pokes a hole in that theory with another theory, and so forth. The problem is that this is essentially people making things up to explain something, much like making up God to explain thunder or famine. You start to get into paradox territory when you start looking at these things from a higher viewpoint, and realize that people are trying to explain something that another person created. It's like asking what time it is. People created time. It could be any time that we choose it to be! /sarcasm

    I've spent many years in the academic realm and many more in the engineering world. I've come to one conclusion. People are full of shit. They want to make their mark on the world and will stop at nothing to do so. I've watched people claim false findings for money, I've been asked to change my stance on a subject to make it more "marketable" and many times I've seen modern science ruin people just because the status quo wouldn't accept that it was wrong even though it truly was. People will always think they know more than they do, (called illusory superiority) some of which are posting in this thread. :)

    I don't knock people for trying, but people who have a need to restate a theory as fact, really need to understand that we'll never know the truth if we keep trying to prove that they are right(confirmation bias). It obfuscates the actual data observations and biases the learners into believing something that may not even be true.

  • @Psyco: I hope my translation is as accurate as possible, but being a native German speaker myself, I cannot be sure it does not skew the intended message of the original author.

    I agree that postulating the existence of things depends on the presence of a human observer is somewhat absurd - this theory easily falls vicitim to Ockham's razor, IMHO.

    Regarding the goal setting of physical sciences, we probably have to agree that we disagree. Whether you call it a masterplan or a fundamental set of rules, I am convinced that no such thing exists, and hunting for it just distracts from creating useful models and theories. It's like if chemists would still hunt for the Philisopher's stone. Such a hunt may yield a useful result from time to time, but filling in the gaps of nearby unanswered scientific questions is much more productive.

    Regarding your examples: Theories like the speed of light being a constant cannot be proven. Mathmatical propositions can be proven (their logical correctness, not the axioms they start from). Physical theories can just be tested, and falsified if observations of reality don't fit, or confirmed if they do. But even if not a single observation contradicts the theory, that is not a logical proof that would be immune to later revision.

    Regarding the speed of light, for example, there is currently a lot of confirmation and no substantial contradicting observation available that "c" might, indeed, be constant. Within a vacuum. But what is a vacuum? Is a space already a vacuum if it is free of any particles that have a mass? Or does it have to be of free of any fields, too - because virtual particles can be formed by the interaction of fields? But then a space with a photon in it would already not qualify as a vacuum. And given that many scientists today, in absence of a better theory, assume that most of the mass of the universe exists in the form of mysterious "dark matter", how can one be sure that any space is without mass in it? Imagine if there was a way to clean a piece of space from "dark matter" that today taints all experimenting rooms - maybe suddenly a ray of light will pass faster through it?

    I for one do not expect to experience the finding of a contradiction to the constantness of the speed of light, in general, but it is not quite impossible that some aspect of reality has not yet been considered in the theories that would make higher speeds possible. There is not and there cannot be a proof for the "c" constantness, there is just strong indication.

    BTW: I like the way that the Loop Quantum Gravity explains the existence of an upper speed limit "c" - sounded more plausible than every other theory to me. But I have neither the time nor the expertise to check all the other aspects of the theory for plausiblity.

  • @karl

    Einstein uses the term "god" here to express what he thinks how nature works - don't take it to literally (it is clear to me from the german original, I don't know how the translation sounds to a native english speaker?). I'm a physicist myselfe and I did read some of his original works - he used the term "god" in his letters to other scientists often to talk about the universe as a whole - just some kind of economic wording, but I did never come across a section where his religious believe was ruling his reasoning.

    Especially when talking about quantum mechanics, he used the term "god" opposed to the "observer". The observer was used by later physicists to put human beeings at the top of the universe - only what we observe is real - which is one of the most stupid things that ever happend in the history of physics. His god here, was just the rest of the universe excluding human beeings (think about his famous question: "Is the moon still there, even when nobody is looking at it?")

    I don't think he believed in a made up masterplan, I think he just believed that a full describtion of the universe with the language of physics is possible - an idea that I share. We have learned a lot about our universe by now - as it follows some rules - but this set of insights are not complete. Can we ever get to the "theorie of everything" (I really do hate those marketing terms) ? I believe, if we have enough time, we might get there.

    And sorry, but physics is not about making some modells - thats a wide spread missunderstanding and one reason why we are not getting anywhere at the moment. Modells are a tool in physics, not its core idea. Physics is about finding and understanding those "rules" that are giving our universe its structure. (Words, like "rules", are a bit missleading, but I can't come up with something better at the moment - my native language is german not english;-) Physics originates from philosophy, not engineering - but at the moment its taught the other way round.

    Some examples for those "rules":

    • constant speed of light (in flat spacetime) / the Lorentz transformations

    • quantum correlation / Bell inequality

    Both are found as the core of there respective theory and later proven by experiment. (Both are not fully understood till now.)

  • After reading through all posts, I am in shock of how many people here are scientifically illiterate and think of themselves as the complete opposite. So far @karl seems to be the most knowledgeable.

    @svart No, just no.

  • @Psyco: We seem to agree that scientists should be a little quicker in scrapping theories that don't fit observations instead of bending them to sometimes unreasonable degrees - but for different reasons.

    Regarding the mind set of Mr. Einstein, which we both didn't meet personally: Einstein certainly did leave the religious community he was born into at the age of 17, and he certainly wasn't a naive believer in some personal god (he clarified his position on this in 1954, in this letter(1)(2).)

    But he was nevertheless making use of religous terms in his reasoning, as in a letter he wrote to Cornelius Lanczos on 21st of March 1942:

    „Es scheint hart, dem Herrgott in die Karten zu gucken. Aber dass er würfelt und sich telepathischer Mittel bedient (wie es ihm von der gegenwärtigen Quantentheorie zugemutet wird), kann ich keinen Augenblick glauben.“
    
    Translation: "It seems hard to look into Gods cards. But I do not believe for a second that he rolls dice and makes use of telepathic measures (as current quantum theory expects from him)."
    

    Maybe it's just a habit of people who grew up in a more or less religious environment to use such terms, and he may not even have put too much thought into using a formulation like this, but to me this wording is a very strong indication that he was definitely dismissing the idea that the universe could exist without some sort of "master plan" setting the rules.

    You wrote: "Physicists are looking for the rules that are underlying our universe, but they didn't find it yet." To this I say (being a physicist myself): No, I am not looking for rules that are underlying our universe, and it is no wonder others did not find them yet, because there is no set of rules underlying our universe. Refined models and new theories can be valuable because they allow better predictions of what happenes in reality, but since there is no core of all things, there is no getting closer to it. The journey (if meant to be the ongoing efforts in science) will not end. (At least not because of finding the universal rule set, it may of course end with the dead of the last life form in the universe capable or willing to do research.)

    So I am all for trying and using different theories and models at the same time. Discard the ones that turn out to contradict reality too much or which have no practical use - and keep the rest around as good tools. And tools are all they are, not master plans.

  • @goanna

    I don't like elementary particles that change there mass/energie every two years because the latest accelerator ruled out the former clamed number - happend to the higgs particle several times.

    Most of the better theoretical physicists hope that they don't find a higgs particle at cern. If the first measurements of the higgs particle are confirmed, they will have a hard time finding a better theory. And we need something to replace quantum chromo dynamics because it has the same problems as every quantum field theory (e.g. infinite field strength at the most interesting locations - the positions of the particles - and no way to combine it with general relativity).

  • @psyco

    Interesting read. What do you find absurd about the higgs particle?
