Even Einstein Doubted His Gravitational Waves (astronomy.com)

Flash Modin writes: In 1936, twenty years after Albert Einstein introduced the concept, the great physicist took another look at his math and came to a surprising conclusion. 'Together with a young collaborator, I arrived at the interesting result that gravitational waves do not exist, though they had been assumed a certainty to the first approximation,' he wrote in a letter to friend Max Born. Interestingly, his research denouncing gravitational waves was rejected by Physical Review Letters, the journal that just published proof of their existence. The story shows that even when Einstein's wrong, it's because he was already right the first time.

      Exactly. I'm not sure what the point is here. And TFS's conclusion is just weird: "The story shows that even when Einstein's wrong, it's because he was already right the first time." Actually, if you read TFA, it has a quote from Einstein himself about how he admitted he got things wrong and sometimes his errors had been published.

      The only vaguely interesting aspect to TFA is how Einstein apparently got upset that someone dared to do peer-review on his paper before simply publishing it. Granted, peer-review was not a universal standard in the 1930s (at least not peer-review by external reviewers -- review by expert editorial boards was standard long before that), but Einstein still seems to have reacted quite poorly in this case... refusing to admit he was wrong, and later finding his error and not acknowledging he could have found it had he listened to the reviewer's criticism.

      The lesson here is NOT that Einstein was always right. He was clearly fallible and recognized himself to be so. On the other hand, he also seems to have a tendency (a natural human one) to refuse to acknowledge errors. That's one of the reasons peer review exists, since scientists often -- consciously or unconsciously -- refuse to see errors in their own logic. TFA's lesson actually shows us that even great scientists can be WRONG, but a proper scientific process can help to weed out those errors.

Technologies come and go, and so do their users and proponents; that's the nature of the beast, and it's going to be reflected on any tech site.

    But the underlying point that the popularity of slashdot at its peak led to an influx of users who didn't probably respect the way slashdot worked, and thus changed the nature of the site, is probably sound. The slashdot moderation system can only work if people moderate with care, and don't just spaff their mod points on the first karma-whore post they come across, or just mod up posts that agree with their point of view. That clearly doesn't happen much, I see so many highly scored posts where it's obvious that neither the posted nor the people that modded the post up have read the article or know much about the subject.

    Meta-moderating is probably even more broken, because it's more effort when meta-moderating to see the context of the post, read the referenced articles, etc. So there are a certain proportion of posts that you can look at in isolation and say they're worth voting up or down, but for the rest, I suspect that even the few people who bother to meta-moderate either skip them or meta-mod them badly without taking the time to look at the context.

What he showed was that given his postulates for special relativity it followed that E^2=p^2c^2+m^2c^4. He was then proven to be correct by experiments not by the maths alone because until those experiments were done his theory might have been nothing more than an exercise in abstract maths.

      Relativistic mass is a misleading and wrong concept which even Einstein himself cautioned against. Mass is something called a Lorentz invariant which means that it never changes no matter which inertial frame you look at it in. The gamma factor in things like momentum, p=gamma*mv, comes from the mixing of space and time which means that the relativistic concept of velocity (the rate of change of position with respect to time) in relativity is not quite what we think of in our everyday world as velocity. Hence the gamma factor has nothing to do with the mass and everything to do with the velocity.

This is the absolute last thing from surprising: every single physical theory we know of so far breaks down at some point. Newtonian mechanics breaks down at high speeds (relative to c). Classical mechanics breaks down in the quantum limit, and is replaced by quantum mechanics. Quantum mechanics breaks down in the relativistic limit (and is replaced by quantum field theory). Most QFT breaks down at high energies, as we can only solve it in the pertubative low-energy limit.

    In the case of GR and quantum mechanics, that's exactly what happens. At low energies, the two work together fine. It's at high energies and short length-scales where the two fall apart (no surprise, as again, both theories were formulated from the low-energy behavior, which is the regime we can perform experiments/observations in quite easily). This is why people are looking for some unified theory that would include both theories in the low-energy regime, and at the same time would work at high energies (this has already been done with electrodynamics and the weak force: at high energies, they become unified through the electroweak interaction). String theory, loop quantum gravity, etc. are all such attempts. So far, we've not been able to perform experiments that would be required to confirm any of them.

    This is off topic, and not a defence of anything that Einstein said, but...

    "God does not play at dice"

    Contrary to what most lay-people believe, quantum mechanics (QM) in no way requires that there be any random element to physics, or the universe in general.

    What leads people to claim QM is "random", is the fact that QM cannot be consistent with all of the following popular beliefs simultaneously:

    1) All physical laws are fully deterministic (non-random).
    2) All macro phenomena (with the possible exception of man's free will) are merely emergent consequences of basic physical law; the whole is not greater than the sum of its parts.
    3) The future cannot be known by any means, other than predicting it by extrapolating from the present state of the physical universe.
    4) If man has free will (in the strongest sense of that term), then any aspect of the future which depends upon his choices cannot be predicted with certainty before hand.
    5) If there is a God, His approach to running the universe is basically hands-off: He established physical law, started things in motion, and then stood back to watch and see what would happen.

    Most physicists have chosen to reconcile QM with their belief system by dropping #1. This is philosophically galling to people like Einstein, because it implies that science will never be able to completely describe or predict the behaviour of the universe. (Of course, there are many non-QM reasons that humanity's knowledge must remain incomplete, as well; for example, Gödel's incompleteness theorems.)

    Ultimately QM is really just a statistical description of how sub-atomic particles behave; it does not answer the question of why they behave that way. Unless it leads to a prediction which can be tested experimentally, interpreting the significance of these statistics is the domain of philosophy, not science. Even among secular scientists, many different interpretations have been proposed; the "randomness" type (in all its many variations) is just the most popular at the moment.

    The pretence (when communicating with the general public) that QM requires randomness is because the science community is predominantly deistic or atheistic, and thus uncomfortable with the grander cosmic order that is implied by any deterministic interpretation. Go too far down that road, and you might begin to suspect that there is a grand Organizer...

    In contrast, the Bible plainly denies #2, #3, #4, and #5. Physical laws are not self-enforcing, but are, rather, enforced by God who is all-knowing, eternal (outside of time), and enjoys a perfect attention to detail - including the hearts of men and women.

    "For all things were created by Him, the things in the heavens, and the things on the earth, the visible and the invisible, whether thrones or dominions or principalities or powers, all things were created through Him and for Him. And He is before all things, and by Him all things consist." Colossians 1:16-17

    "He telleth the number of the stars; he calleth them all by their names. Great is our LORD, and of great power: his understanding is infinite." Psalms 147:4-5

    "For the word of God is living and powerful and sharper than any two-edged sword, piercing even to the dividing apart of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. Neither is there any creature that is not manifest in His sight, but all things are naked and opened to the eyes of Him with whom we have to do." Hebrews 4:12-13

    My points above were simply that:

    1) QM does not require randomness.
    2) The reason that scientists often make it sound like it does, is because this best suits their deistic/atheistic world view, as it is furthest from the truth.

    How is it that our words have meaning, and that we can perceive it? How is it that you are experiencing this conversation?

    A mere sack of chemicals might indeed respond to the stimulation of the ears by stimulating the muscles of the mouth to produce complex sounds with complex mathematical correlations between the two. But, I'm not just a Chinese room; I am a living, thinking, feeling being who experiences life in a way that physics knows nothing about.

    I cannot prove (to myself) that you are not just a sophisticated simulation of a human being, but I know that I am the real thing and have an immaterial soul:

    "I think, therefore I am."

    This is proof positive that physical law (as it is understood today) is an incomplete description of reality: we know that there is something more; the question is, what?

    The mystery deepens when we take a step back and ask the question, "How can I know, or prove, anything?"

    In order to reason, we must first assume that the fundamental laws of logic are valid, and that we have the faculties required to apply them with some accuracy. But, this appears to be an unfounded assumption: where did it come from? Why do we trust logic so much that it makes us angry when others are illogical?

    People will often respond to this, "They've always worked for me in the past." This is circular reasoning, though - how did you conclude that they worked for you in the past? How do you know that the future will resemble the past? By the laws of logic.

    Mankind's innate grasp and love of logic are a precious gift from our creator:

    "For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves: Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another..." Romans 2:14-15

    God has written His law upon the hearts of all men and women, and a prominent feature of that law is this: "You shall not bear false witness." (To understand and obey this law necessitates some grasp of logic; otherwise "false" becomes meaningless.)

    It is because of this universal law written upon our hearts, that you expect your opponent in a debate to be affected by your use (or abuse) of logic. You expect others to be ashamed when they are illogical or lie; if this were not so debate and rational argument would be a pointless exercise in all contexts.

    We cannot ultimately know anything by ourselves, because no finite logical system can ever be proven to be correct, consistent, and complete by itself. An infinite regress is required, according to the likes of Gödel's incompleteness theorems.

    And yet, mankind does know things: you know that it is wrong to lie. (Otherwise, why are you arguing with me?) This seed of innate knowledge - upon which all other human knowledge must rest - is itself given to us by the eternal, infinite, transcendent God of the Christian Bible who is all-wise, all-knowing, and unchanging.
