      How can they still claim the universe is around 13 and a half billion years old, due to rewinding the expansion when they are now telling us dark energy is speeding up the expansion? Seriously, can anyone explain why the age has not been adjusted if dark energy theory is right. Not in the 5 years I've been asking has anyone been able to tell me

  • @robertmartin513
    @robertmartin513 4 года назад +8

    I have about as much exposure to cosmology and physics as the next interested guy but this utterly blows my mind. What an incredible story. I've long held the suspicion that despite our best efforts weve tripped somewhere along the way in our efforts to define our universe and that taking a phorensic expedition into the origins of this blunder would be so catastrophic to our current estimations that we would have to scrap an enormous margin of what we believe to be truth in order to get on the path to discovery of the real truths of the universe, rendering most of science all but useless and contrived. I'm sure of shared sentiment when I say this is terrifying. I hope, on the other hand, that there are just more discoveries along the way that tie up the loose ends.

    • @rickb06
      @rickb06 2 года назад

      I tend to agree with your assessment, Robert. In the flamboyantly Russian words of an actor from the film Armageddon: "I told you, you took a wrong way, a wrong road.”
      At some point between Hubble, and Einstein, we (humanity, et al.,) fumbled our theories, and stopped caring about how our theories matched up against reality and our observations of it. Einstein was described by many early astrophysicists and astronomers as being "blind to the fact that a forest exists beyond the trees that so fascinate him". Any time that one single human being's name and likeness is associated with an astronomical amount of so called discoveries, and those discoveries remain scientifically unchanged for over a century; that fact would seem to indicate that we've been set on a wild goose chase for a century.

    Douglas Adams may have been on the right track when he wrote:

      There are a handful of TV presenters* who do a great job of drawing you into their subject with enough depth to entice, and whose knowledge and enthusiasm naturally engage the viewer without the need for OTT effects, overly dramatic music, and 'talking years' forever telling us how wonderful / mysterious / unbelievable something is without adding to the content. When you also subtract from the latter kind the all-too-frequent recaps to cater to the and breaks (and ours in Britain now rival the American ones), if often leaves very little time for anything educational.

      @Astute Cingulus "Agnosticism is a state of confusion of the thinker. "
      Agnosticism is not the simultaneous assertion that God does and does not exist, which would be a contradiction. It is the frank admission "I do not know", which concept is fundamental to the toolbox of any scientific or academic investigator. The notion that the recognition of logical dilemma is the same as the resolution of the dilemma is a state of confusion of the thinker.

    Maybe that smart guy can blast me too, gentlemen. The fact that a majority of scientists supports a theory or believes today that the age of the universe is 13.8 billion years is acknowledged. But it does not mean it's true.
    As the narrator in this clip states, it's big and I may add: there is nothing that proves it's finite.
    The statement "we are twelve billion light-years from the edge" in a song is no reason to "BLAST" someone.
    This distance is just an estimate and indicates nothing about possible infinity beyond that "edge".
    As an observer we are always in the "center" of an observable sphere. Think of a diver in a murky ocean. He may see hundreds of fish nearby, but the sphere that limits his view is not automatically the scientifically proven size of the ocean. The sphere is that big - the universe can be much bigger or infinite. Or transformed into time, the universe maybe that old or much older or eternal. Think about it and use your math properly.
    And you can blast me if you wish - but it won't make your theory more true!

    My guess is the inflationary epoch was caused by vacuum decay, which in addition to releasing an enormous amount of energy, also resulted in the separation of the 3 particulate forces (electromagnetism, strong nuclear, and weak nuclear). I'm not convinced that gravity _can_ be unified with the rest, as it appears to operate fundamentally differently. But I suppose it's possible that the Big Bang itself was caused by a vacuum decay that resulted in the separation of gravity from the 3 particulate forces.

      @Shawn I'm with you on gravity not being the 4th force. There is no doubt that something is different about gravity that makes it a strong force to hold objects (planets, galaxies, etc) together yet also so weak that a .99 cent magnet put on your refrigerator can defeat the force of gravity. Also I'm thinking that maybe gravity isn't everything we make of it and electromagnetism is really the force that shapes and keeps everything together and in order. Just my 2 cents.

      @@morningbite2023: Electromagnetism doesn't shape the universe. Electromagnetism, like the other particulate forces, can be repulsive as well as attractive depending on charge. Gravity is unique in that similar gravitational "charges" attract instead of repel -- in fact there is no known physical manifestation of repulsive gravity -- which is why gravity can pull countless fucktillions of particles together across millions of light years of distance. Electromagnetism can't do that, because every electromagnetically charged particle has a 50% chance of encountering another electromagnetically charged particle with a similar charge and repelling it instead of attracting it.

      "The BIG Bang-Bit Bang inflation/expansion of energy and information into the void 13.8 billion years ago was a supermassive white hole spawned by a supermassive black hole at the heart of a galaxy in our 'parent universe'. This duality combines general relativity’s singularities of infinite density in a ‘Cosmic Egg’ birth of this and all universes within 'The Conglomerate': multiverse without random bubble universes and parallel worlds. Our Universe is inside the Planck density of that SBH and shares the same event horizon. That SBH-SWH seed phase transition was a 'quantum tunneling umbilical wormhole' with energy-matter and data transformed/transferred, albeit scrambled and encoded. Our Universe is 1-in-2 trillion 'self-similar offspring' each with the same inherited physical laws (‘DNA’). This simple cause-and-effect cycle/'circle of life' - birth-life-death-transformation-rebirth - explains both infinite space and eternity.

    Best science video I've seen in youtube, ever!
    Yeah, I never trusted and still don't trust Cosmology.
    Back of the envelope math:
    Say we observe a galaxy 12Bly away, and red shift is such that it seems to be moving away at c. How long ago was it "here" (near the place the big bang happened)? Well, even assuming constant speed, 12Byr to get there PLUS 12Byr for light to get back, so the universe would have to be 24Byrs old.
    There's also the superluminic early expansion and the mother of all slammings on the break.
    Given just those 2 megabsurdities it's a gigabsurdity to introduce dark this and dark that to fix minute problems in an island of theory in an ocean of contradictions.
    WMAP produced it's own contradictions by declaring the universe flat (with local curvature cases, but generally flat). The contradiction with that conclusion is that the whole premise of WMAP is that those stretched photons from the big bang are visible to us BECAUSE THE UNIVERSE IS CLOSED, so they've been going round and round. If the universe is flat, the only way those photons could be coming back is if the edge of the universe is mirror plated. Where did the silver or aluminium come from?
    Another similar crisis exists regarding the diameter of the proton, which when measured using moronic hydrogen yields a diameter that differs by 5% or so from other methods.
    Conceptual misunderstandings abound in science, too, like the idea that the Michaelson Morley experiment disproved "the ether". The ether was misconceived as a medium on which EM waves propagate LONGITUDINALLY, like sound waves. If that were true, indeed a speed vector in the medium would affect propagation.
    But nobody seems to have questioned this longitudinal assumption.
    When waves are transversal to the medium, such as waves on water, the waves' motion is not affected by motion of the medium (e.g. stones into river cause expanding, circular waves with a stationary center, regardless of water flow).
    The only thing Michaelson Morley proved is that EITHER there is no ether, OR that relative to the ether EM waves are transversal, --which should have been obvious...

      1) As Tommy said, your initial assumption is incorrect. Astronomers don't observe light that is _reflected_ off distant objects, they observe light that was _emitted_ by distant objects. There is no need for a "mirror-plated universe".
      2) Why are you assuming a constant rate of expansion? There is no evidence to support a constant rate of expansion. In fact, there is an increasing amount of evidence to support that the rate of expansion was initially very fast, followed by a decreasing rate of expansion, followed by an increasing rate of expansion that started a few billion years ago.
      3) If a galaxy were moving away from us at _c,_ we wouldn't be able to see its light at all -- some galaxies are _extrapolated_ to _now_ be moving away from us at _c_ or even faster thanks to expanding space, but that's based on light that we can see which was emitted when they were moving at a speed less than _c._
      4) Of course transverse waves are affected by movement of the medium through which they pass. That's why turbulence from a waterfall doesn't propagate upstream (the waterfall is effectively an event horizon), and that's _also_ why light emitted from distant galaxies is redshifted. As for your example of throwing a rock into a moving stream, next time pay attention to the _location_ of those waves _relative to the point where the rock entered the water._ You will see very clearly (if the water is clear and you can see where the rock landed) that the circular ripples are moving downstream. It is only due to your own disconnection from the medium (i.e. the water) that you are able to observe the ripples without a Doppler shift.

    Everyone first time arriving here might have thought this is just a boring bed story to help to sleep . But it isn't , instead it's the otherwise , it makes your brain think and probably in some cases it makes u can't sleep with the overflowing ideas, dopamine and chemical rushes in the brain as you think about the real world . Good job indeed ParallaxNick , i found your channel on "accident" , and i never regret it , you deserve more views and subscribe.

    I have been teaching Physics and Astronomy for 20 years. There are many other experimental results that neither GR or QM can explain. Particle Physics also faces monumental problems.
    However, attempting to accurately date the Big Bang has brought it all to a head.
    To me, both GR and QM must be approximate. They must be discarded as foundational assumptions. However, for the past 50 years, GR and QM have been treated as religious tenets.
    Physics won't progress until a groundswell of Physicists agree that it is OK to propose alternative foundations.
    Unfortunately, the vast majority of academic journals flat out reject any attempts to formulate alternative foundational postulates.
    A culture of exploration needs to return to fundamental Physics.

      Agree that there is a near religious devotion to relativity (among other things). Seeing the same fervor across the board in academe. Seems to me there is a movement away from empiricism broadly in the culture. Figured that physicists would be less susceptible to groupthink and willing to challenge assumptions when faced with facts, but...

    I think the Universe is simply eternal without begging or end, and is not expanding as the Tolman surface brightness test indicates. The SN Ia dilation that purported to prove expansion were likely an error resulting from an over assumption of the standard-candle nature derived from Chandrasekhar limits which ignore many other aspects like rotation and magnetic fields which can vary the mass and magnitude of the SN.

      Type 1as are only one standard candle. There are others, like cepheid variables. And I don't see how measuring the brightness of our nearest star could have an impact on the values of galactic motion.

    I know that the statement that, "The universe is one big star...", was mostly metaphorical...
    But, just imagine it in a literal sense.
    Imagine humans, one day achieving the necessary technology, to travel at great enough speed... to reach the "edge" of the universe... and BEYOND.
    Imagine our "craft", traveling outward... through the various layers, experiencing the requisite changes in temperature, etc... until finally "popping out" of the Corona of "the star that IS our universe"... and INTO A GREATER, COMPLETE UNIVERSE OUTSIDE OF IT...
    Someone should scifi the sh*t outta this idea, lol.
