    A lot of videos have covered the general overview of the discovery of gravitational waves, what they are, the history of the search, when they were found but I wanted to delve into the absurd science that made the detection possible.
    When scientists want one megawatt of laser power, it's not just for fun (though I'm sure it's that too), it's because the fluctuations in the number of photons is proportional to their square root, making more powerful beams less noisy (as a fraction of their total). The smoothest mirrors were created not for aesthetic joy but because when you're trying to measure wiggles that are a fraction the width of a proton, a rough mirror surface simply won't do.

    So basically this is just a REALLY REALLY precise way of measuring redshift and as a result the expansion and contraction of space. So does that mean it could also be used to measure the expansion of the universe and therefore locate the location of the centre of the big bang? Perhaps this would give us a better understanding of how far the potential edge of the universe is beyond the limits of what was previously the "observable" universe?

    If I made the arms 40 km long, would I only need to measure to 1/100th of a proton, or at 400 km would it be just 1/10th?

    Do the gravitational waves carry energy (on top of spactime) that make the waves? Or is the "energy" inside of spacetime's fabric propagating out around the universe?
    I want to know if there is energy riding with the waves or is the energy transferred into spacetime's "fabric" causing gravity that has separated from its original source. Gravity that is independent of mass.

    Could these gravitational wave detectors be built for the moon? Granted I am totally an amateur here, but I see the hardware being much simpler. No need for tubes to create a vacuum, the surface of the moon is almost a perfect vacuum. No need for all that hardware to isolate from the noise of our civilization. Just three laser and detector packages that could be launched from earth and set down on the moon. If the packages had wheels, they could literally inch themselves into the proper positions with respect to each of the other two detectors.

      What is pseudo-science is the way your using those.
      Of course molecules vibrates, that's thermal agitation. Of course vibrating moves of electric charges causes EM waves, that's the very principle of an antenna.
      But that's not "specific", neither "far above gamma" : for most part, at room temperature, thermal agitation will generates a very weak infrared emission, that thermal camera will be able to measure.
      You have some specific resonances frequencies for most molecules (not for metals, as they have a Fermi sea). Unless specifically designed, however, those frequencies are not an heavy part of the spectra. An everyday use of such a frequency are micro-wave oven that send an em wave at the main resonance frequency of water molecule (H2O) and so efficiently transfer energy to them (so that they heat).
      But anyway, that doesnt makes "all things vibrating to a specific frequency", and even less explain gravitation (that depend on the *mass* ) being done by *charges.*

    • Yohen Sevtstein
      Yohen Sevtstein 14 дней назад

      Probably censored, I just sent links to the wiki pages of Atomic Vibration and Molecular vibration. Just so you know they're not pseudo scientific words. I don't claim to know everything, or that I'm even right about most things I've said, but most of it has just been stating what we as a species have already discovered, that moving electric charges emit electric fields. I also stated the resonant frequency of cancer, if you cared at all. I'll remove the links, maybe that'll fix it.

      What is the "Lorentz force"? Thanks.
      And why cant you answer most of my questions?
      Let me suggest why: in fact you dont have any idea of the answer. "vibration" is a kind of buzzword you use, without knowing what it may refer to. Like the others. It's some pseudo-science word salad that looks like saying something, but in fact dont. I asked you several time to provide figures (like what is the actual frequency of what you are referring to, etc.), but you cant answer, because you dont know. Again because that's not science, but buzzwords.
      I invite you to think about it.
      Anyway, if you think you have something sound to teach me, I'm reading carefully: just answer my questions :-)

    This is easily the most interesting and clearly presented video by Veritasium ever. One concern I have is the nature of interpreting interferometry results, generally. When one looks back at the Michelson-Morely experiment, it's not very clear what their actual experimental results meant. We are told a seemingly coherent story from our modern physics textbooks in Freshman year of undergrad, but this does not hold up to scrutiny. It seems like there may be some fundamental assumptions going into the interpretation of interferometry data, which produce misleading interpretation of outcomes, and subsequent mis-processing of data and certainty.

    Something suspicious about this research.
    I remember watching the initial video where you spoke about them finding the waves.
    It was something like, in all of mankind, in all history and in future. The only time they had to detect those waves was the exact time they turned the machine on... And they couldn't believe it. A year earlier would have detected nothing and a year later they would have deteced nothing. It's like the won the lottery 15000 weekends in a row.
    And then we have things like "Measuring the waves is like measuring a varation in the distance from earth to Alpha Centurai with the width of a human hair"
    So we built something HUGE... 4km? That is not huge. That's like saying "I built a 0.0000000000000000000000000000000001m fishing rod to try and catch fish at the very bottom of the Mariana Trench"

    Actually the notion of gravitational waves is absurd. The tiny deflections detected are simply due to the massless, chargeless positrons and electrons striking the detector. Study the Reciprocal System and prove it for yourself. www.reciprocalsystem.guru

    You seem to have missed an important point about the wavelength of the gravitational wave. Or am I just confused? It has to be long. Longer than the detector in any distance. But then, if it is travelling at the speed of light, I don't understand the explanation that 'the next photon has to travel through more space'. Because... no, only those caught in the gravitational wave would be travelling through more space, or longer time. Or less space, and less time.

    *\/ \/ PROOF BELOW THAT LIGO ITSELF DEBUNKS GRAVITY \/ \/*
    If you read on LIGO's website, (QUOTED BELOW) you will find that they had to account for the curvature of the earth when building the vacuum tubes of LIGO, which means that the LIGO people understand that the gravitational pull of earth has NO EFFECT on the course of the laser. However, if the earth's gravitational pull has no effect on the laser, then we can all agree and say that the sun's gravitational pull has no effect and if gravity has no effect on light (besides this stretching of space-time from black holes that LIGO claims they are measuring), then according to the laws of light and gravity, no matter whether the earth is stationary in space or moving at 100,000,000 mph, the light should head in a straight path unaltered by gravity. HOWEVER, the light in each of LIGO's "arms" goes back and forth for OVER 690 miles before recombining with one another in 1/270th of a second. And in that 1/270th of a second, the earth has rotated 5.44 ft, and orbited the sun for 362.36 ft, and our solar system has moved towards Lambda Herculis by 235.05 feet.
    BUT SOMEHOW LIGO'S LASERS HAVE NO PROBLEM BEING LINED UP PROPERLY WHEN THE EARTH IS GOING EVERY WHICH DIRECTION AND THE LASER IS GOING IN ONE DIRECTION REGARDLESS OF IT'S ENVIRONMENT... LIGO PROVED SOMETHING -- THAT GRAVITY AND THE WORLD AS WE UNDERSTAND IT JUST DON'T MAKE NO SENSE.
    LIGO QUOTE: VERY INTERESTING!!!
    "LIGO's arms are long enough that the curvature of the Earth itself was a complicating factor when installing the vacuum tubes. It wasn’t enough for LIGO’s civil engineers to smooth a level path and assemble each arm’s tubes in a straight line. To ensure a perfectly level beam path, the Earth’s curvature (more than a vertical meter over the length of each arm) was countered by GPS-assisted earth-moving and high-precision concrete work."

    Einstein never predicted gravitational waves come from two black holes collide or come from explosion. He didn't believe in black holes. He is the reluctant father of black hole.
    He predicted:" Two celestial bodies IN ORBIT will generate invisible ripples in spacetime" (Einstein's manuscript 1916).

    • John Wagner
      John Wagner Месяц назад

      Yes, I am aware that light IS supposed to be affected by "gravity". I am saying that LIGO scientists and people ALL OVER THE WORLD say that light is affected by gravity, BUT, LIKE YOU SAID, the effect on the light's path is MINIMAL. People also say that the light doesn't necessarily bend from gravity, but that the space around light bends making it appear that the light must be bending. I've heard quite a bit and am familiar with the theories on relativity and how they work.
      I am ONLY SAYING that the LIGO project disproves those "well established" theories by the fact that the laser system ACTUALLY WORKS FOR OVER 690 MILES OF BOUNCING BACK AND FORTH in EACH of the INTERFEROMETERS ARMS THAT ARE PERPENDICULAR TO EACH OTHER,, WHICH WOULD BE IMPOSSIBLE IF THE EARTH WAS MOVING & GRAVITY AFFECTED LIGHT OR DIDN'T EFFECT IT'S PATH AT ALL!!--EITHER WAY, NOTHING MAKES SENSE WITH THIS EXPERIMENT WITH THE WAY THAT THE MAJORITY OF PEOPLE VIEW & UNDERSTAND THE WORLD.
      This is the problem with scientists these days, they jump from the theory of relativity to quantum mechanics and back and forth to different theories and laws until they have something that makes sense if you don't think about it for too long..

    • Ashmeed Mohammed
      Ashmeed Mohammed Месяц назад

      light IS affected by gravity, just like everything else.
      there are two problems with that:
      one is that light moves so fast, that the effects are not as obvious compared to other things in space.
      the second is that gravity isnt real. its just a convenient term for referring to the bending of space/time with respect to concentrations of mass.

    • John Wagner
      John Wagner Месяц назад

      Ashmeed Mohammed Yes! that's what I was saying. You would NOT have to account for curvature if light WAS AFFECTED by gravity, BUT LIGO SCIENTISTS CLEARLY know that it isn't which is why they accounted for it. And yet we move throughout space at millions of miles per hour and it has NO EFFECT on TWO SUBATOMIC PARTICLES OF LIGHT BOUNCING AROUND FOR OVER 690 MILES AND THEN CANCELLING EACH OTHER OUT??
      The $620 MILLION DOLLAR LIGO project successfully disproved the theory of relativity which they were trying to prove by confirming the presence of black holes.

    A 1MW CW-laser is impressive, sure. But two Tesla-model-S' can also produce 1MW power. 1 MW in and of itself isn't impressive at all. I'd like to see a household running on 1kW, by the way. The earth would be 'green' overnight.

    Why is time dilation no concern to LIGO? to my understanding: if the gravity wave hits one leg of ligo it will get a tiny bit larger than the other one and thus create a interference pattern of the laser beam. now if the extent of space changes, shouldnt the duration of time change accordingly and thus cancel the effect? whats the mistake I am making? where am I wrong?

      If you read on LIGO's website, (QUOTED BELOW) you will find that they had to account for the curvature of the earth when building the vacuum tubes of LIGO, which means that the LIGO people understand that the gravitational pull of earth has NO EFFECT on the course of the laser. However, if the earth's gravitational pull has no effect on the laser, then we can all agree and say that the sun's gravitational pull has no effect and if gravity has no effect on light (besides this stretching of space-time from black holes that LIGO claims they are measuring), then according to the laws of light and gravity, no matter whether the earth is stationary in space or moving at 100,000,000 mph, the light should head in a straight path unaltered by gravity. HOWEVER, the light in each of LIGO's "arms" goes back and forth for OVER 690 miles before recombining with one another in 1/270th of a second. And in that 1/270th of a second, the earth has rotated 5.44 ft, and orbited the sun for 362.36 ft, and our solar system has moved towards Lambda Herculis by 235.05 feet.
      BUT SOMEHOW LIGO'S LASERS HAVE NO PROBLEM BEING LINED UP PROPERLY WHEN THE EARTH IS GOING EVERY WHICH DIRECTION AND THE LASER IS GOING IN ONE DIRECTION REGARDLESS OF IT'S ENVIRONMENT... LIGO PROVED SOMETHING -- THAT GRAVITY AND THE WORLD AS WE UNDERSTAND IT JUST DON'T MAKE NO SENSE.

      @tommy: a general purpose dictionary may not be good enough. But the important thing to remember is that in science, a "theory", is not synonym to "speculation", when a theory is well established, it's the highest level of scientific confidence (and for a theory to be falsified, you would have to have at least one of the facts or laws it rely on shown wrong).
      But lets come back to Big Bang.
      How do you explain red-shift? How do you explain uniform radiation background at 4K ?
      How do you explain current He/H ratio?
      ... and tons of other observations that only makes sense in a big-bang model.
      If you have another better one, feel free to publish: you'll get the next Nobel...

      Thomas Kundera "a theory is never upgraded to a fact or law because it is higher than both of them combined." Sorry dude I cannot follow you down that rabbit hole. That is simply outrageous. I don't know where you got your definitions from but according to Webster dictionary a theory is" a plausible or scientifically acceptable general principle or body of principles offered to explain phenomena"
      Based on this definition I cannot follow your supposition of "a theory is higher than a Law or fact" Just telling you we are not gonna see eye to eye on any occasion so this conversation is pointless. I appreciate the time you take in your thoughtful answers but If you think a theory is "higher" or better than a "FACT" you are out of your mind.

    • Thomas Kundera

      @tommy: short lesson in science language, may be useful to you:
      Do you mean like the germ theory of disease, the oxygen theory of combustion, the theory of plate tectonics, quantum theory... Did I mention electromagnetism is "just a theory?" As is ionizing radiation. The fact that every living human on earth breathes oxygen and exhales carbon dioxide is "just a theory." Let's make one thing absolutely abundantly clear: You are shamelessly conflating a scientific theory with a tentative guess or hunch. A theory is never upgraded to a fact or a law because it is higher than both of them combined! By definition a theory must be accurate, correct and PROVEN in order to qualify as a theory in the first place!
      You seriously need to learn the imperative differences within the scientific hierarchy:
      *HYPOTHESIS:* A tentative or educated guess, hunch or approximation that is testable and repeatable through observation and experiment. Hypotheses are often conflated with theories by laymen.
      *PREDICTION:* A supported hypothesis.
      *FACT:* A simple indisputable data point derived from predictions that can be explained through observation and experiment. The hypotheses surrounding facts are never nullified.
      *LAW:* Laws serve as excellent universally applied mathematical descriptions, quantifications and measurements of facts, but can't tell us anything about HOW that fact actually works or WHY it occurs.
      *PARADIGM:* A "fact web." A succinct collection and reservoir of well proven & organized facts and laws from which we can begin to derive & induct solid explanations. Paradigms also envelop a set of concepts or thought patterns, including research methods, postulates, and standards.
      *THEORY:* Now we're really gettin' up there. Facts & laws would be nothing without a well documented, well substantiated explanation as to how and why they occur or behave the way they do. Theories form comprehensive and accurate bodies of scientific knowledge with backbones of proven hypotheses & predictions. Theories are constantly updated with new facts about the mechanics of nature and cannot be falsified no matter how hard we try. When scientists refer to an explanatory model as a "theory," they are literally giving it the highest possible praise. In that sense Newton's theory of gravitation is a "theory".
      *THEORETICAL MODEL:* (The application of a theory). A coherent indisputable paradigmatic framework that has astonishing predictive and explanatory power from which we derive all knowledge, develop all practical applications, formulate hypotheses, accurately predict future facts that we have YET to observe thus far, and test new hypotheses with outstanding results.
      Theoretical models win Nobel Prizes!
      Got it?

      Thomas Kundera the only main point that I am bringing to the table is that I strongly disagree with people using something that is theorized as a cold hard fact as we see in the video above. The point is not that I could come up with a better model but that we look at all theories as theories and simply that. To say a theory is a fact defeats the purpose of it being a theory. I just don't like people calling theories facts thats all.

    • Thomas Kundera
      Thomas Kundera 16 дней назад

      @tommy: _"The big bang is THEORIZED as coming from nothing"_
      No, that's wrong.
      _"If you cannot explain how it began then how can you explain how it came to be."_
      The BB theory doesnt answer to the question "how it being". It explain *how it changed from some point.*
      Got it?
      _" I would never say we know "nothing" about the universe, not at all."_
      Good.
      _"But to claim that we know exactly what happened and when."_
      Nobody claims that. For example, I lost my keys last week, and even Nobel winners dont know where they are.
      _"I am disagreeing with the terminology and claims that this theory is a fact."_
      Just means you dont understand what a theory is.
      In any case, if you have a better model than then Big-Bang to explain what we can observe, I'm reading you. Feel free to explain yourself.

      @John: you obviously missed elementary lessons about Galilean equivalence of referential.
      Imagine I'm in a big boat, on a calm sea, inside a room without any window, and I'm playing basket-ball.
      - Could I know if the boat is moving from the inside of the room?
      - would my dribble be affected and would I have to adjust for the moves of the boat, if it is?
      Answer to that question is very simple: as long as there is no acceleration, absolutely not.
      So even if the boat is cruising at 50 km/h, or if, instead of a boat it's a plane flying at 800km/h, all physics inside the room will be same, and I wont have the slightest way to see, from inside only, that I'm moving.
      And it worth as much for the ball than for a photon dribbling on mirrors...
      It just means that "moving" is not some "absolute" concept, but just relative one: I'm moving *relative to* something else (the Earth ground, for example), but this is formally equivalent to say that I'm not moving at all, and that it's the Earth that is moving relative to me.

      Got it?

      Okay. So why don't we just start with just one of your comments where we both agree on something. But first off, I am not trying to put you down and I don't want you to try to put me down. I just want to go over this and possibly learn some stuff as we go along.
      YOUR comment: *"Earth rotates 360°/24h, so 0.05'' in 1/270s. A very very small angle that is just corrected when aligning the beams."*
      So since you are stating that they can just align the mirrors to make the experiment work, WE BOTH AGREE that earth's gravitational pull and the rotating of earth on its axis has nearly 0 (ZERO) impact on the ORIGINAL trajectory of the laser light for this LIGO experiment.
      BUT, the way that you are SIMPLIFYING the solution to this problem just DOES NOT work. Because the earth is ROTATING, it is not moving in a single direction, but the direction is CONSTANTLY changing in the 1/270th of a second. So that means that you would have to NOT ONLY ANGLE the mirrors DIFFERENTLY EACH TIME THAT THE LASER BOUNCED OFF THE OTHER MIRROR, but you would also have to move them several feet just based upon the earth's rotation alone and not counting all the different ways that we are moving through space.
      AND, your solution to this problem does not account for the fact that the INTERFEROMETER'S ARMS are perpendicular to each other. THIS means that the spinning of the earth and would cause different problems in one arm than it would in another.
      NOT TO MENTION, if you account for the rotation of the earth then you must account for all the other ways that we move through space. AND YES, I am well aware that we only say the earth is spinning at 1000 mph and that we are orbiting around the sun at 66,666 mph, but it is all relative based upon what planet you are looking at it all from, BUT LIGHT DOES NOT HAVE THE SAME PERSPECTIVE AS YOU & ME, LIGHT JUST GOES STRAIGHT AT A CONSTANT SPEED NO MATTER WHETHER THE GROUND UNDERNEATH ITS FEET IS MOVING OR NOT. AND THIS LIGO EXPERIMENT, & THE FACT THAT THEY HAD TO ACCOUNT FOR THE CURVATURE OF THE EARTH BECAUSE LIGHT IS ONLY MINIMALLY EFFECTED BY GRAVITY, PROVES THAT PARTS, IF NOT ALL, of the THEORY OF RELATIVITY *IS WRONG*.

      @John: _" (QUOTED BELOW) you will find that they had to account for the curvature of the earth when building the vacuum tubes of LIGO"_
      No surprise.
      _"which means that the LIGO people understand that the gravitational pull of earth has NO EFFECT on the course of the laser."_
      Earth gravitational field is very weak, so light wont be much affected by it.
      _"then we can all agree and say that the sun's gravitational pull has no effect"_
      Not measurable one, likely.
      _"then according to the laws of light and gravity, no matter whether the earth is stationary in space"_
      Define "stationary"?
      _"or moving at 100,000,000 mph"_
      Relative to what?
      _"the light should head in a straight path unaltered by gravity."_
      It is altered by gravity, but unless very strong field, it's hard to notice.
      _"in that 1/270th of a second, the earth has rotated 5.44 ft"_
      Wrong unit. A "rotation" is not measured in linear unit (whatever middle-age unit you use).
      Would you rather say "at that point, turn 90° left" or "at that point, turn 20m left"?
      The second has no meaning, agree?
      Earth rotates 360°/24h, so 0.05'' in 1/270s. A very very small angle that is just corrected when aligning the beams.
      _"and orbited the sun for 362.36 ft, and our solar system has moved towards Lambda Herculis by 235.05 feet."_
      Those moves are about exact translation: they dont affect physics in any way.
      _"BUT SOMEHOW LIGO'S LASERS HAVE NO PROBLEM BEING LINED UP PROPERLY WHEN THE EARTH IS GOING EVERY WHICH DIRECTION AND THE LASER IS GOING IN ONE
      DIRECTION REGARDLESS OF IT'S ENVIRONMENT..."_
      Yeah, no problem. (You have a problem with your keyboard?)
      _"LIGO PROVED SOMETHING -- THAT GRAVITY AND THE WORLD AS WE UNDERSTAND IT JUST DON'T MAKE NO SENSE."_
      No, you just proved you dont understand gravity and modern science.
      I suggest you to dig the relativity concept (classical one, first).
