      @Brad Watson ⁰knowledge of field is incomplete without that of its witness , observer or knower in context to both micro and macro , part and whole ,one and . many . According to the Bhagavat Geeta ,true knowledge constitutes the right knowlede of both field (khetra) and ( khetranjna) knower of the field in all levels of existence or reality . Their interactioñ is so meaninggul that evolution of life not only is initiated but also consumated in principle through replication and self realization

    Thanks for a great talk. As to the man questioning the veracity of language in describing modern physics: language is a system. All systems are finite by definition. That means that there will be things outside its 'wheelhouse'. I doubt you could describe your favorite painting well enough for me to picture it in my mind anything like you see it. Oh, I might get a feel for colors, composition, & such, and I might even catch some glimpse of what it means to you. But I'd really have to see it for myself; something you'd almost certainly be quick to tell me. But science communicators - especially those who are actually practicing scientists - have not only words, but pictures, as well as math at their own disposal. Plus the fact that as scientists, they've 'seen it for themselves'. They do their best to share all that with us, but it's not easy! There is some truth in saying that areas of modern science - particularly particle physics and cosmology - have become increasingly abstract, and that makes a science communicator's job all the harder. There's also the jargon barrier. All organized institutions have at least a bit of their own language; terms that only apply to their specialty. Parsec is good example from cosmology. The light year that we're familiar with is not something cosmologists often use among themselves. They use the parsec. They also all use metrics; even here in North America (except when NASA forgets!) So there are plenty of challenges to keep an honest science communicator busy! Thanks again. tavi.

Who will be the characters alive and working today that will be the protagonists populating the great science stories told to enthralled audiences the world over?

    From Job 38 (The Message Translation)
    ...
    Where were you when I created the earth?
    Tell me, since you know so much!
    Who decided on its size? Certainly you’ll know that!
    Who came up with the blueprints and measurements?
    How was its foundation poured,
    and who set the cornerstone,
    While the morning stars sang in chorus
    and all the angels shouted praise?
    And who took charge of the ocean
    when it gushed forth like a baby from the womb?
    That was me! I wrapped it in soft clouds,
    and tucked it in safely at night.
    Then I made a playpen for it,
    a strong playpen so it couldn’t run loose,
    And said, ‘Stay here, this is your place.
    Your wild tantrums are confined to this place.’
    12-15 “And have you ever ordered Morning, ‘Get up!’
    told Dawn, ‘Get to work!’
    So you could seize Earth like a blanket
    and shake out the wicked like cockroaches?
    As the sun brings everything to light,
    brings out all the colors and shapes,
    The cover of darkness is snatched from the wicked-
    they’re caught in the very act!
    16-18 “Have you ever gotten to the true bottom of things,
    explored the labyrinthine caves of deep ocean?
    Do you know the first thing about death?
    Do you have one clue regarding death’s dark mysteries?
    And do you have any idea how large this earth is?
    Speak up if you have even the beginning of an answer.
    19-21 “Do you know where Light comes from
    and where Darkness lives
    So you can take them by the hand
    and lead them home when they get lost?
    Why, of course you know that.
    You’ve known them all your life,
    grown up in the same neighborhood with them!
    22-30 “Have you ever traveled to where snow is made,
    seen the vault where hail is stockpiled,
    The arsenals of hail and snow that I keep in readiness
    for times of trouble and battle and war?
    Can you find your way to where lightning is launched,
    or to the place from which the wind blows?
    Who do you suppose carves canyons
    for the downpours of rain, and charts
    the route of thunderstorms
    That bring water to unvisited fields,
    deserts no one ever lays eyes on,
    Drenching the useless wastelands
    so they’re carpeted with wildflowers and grass?
    And who do you think is the father of rain and dew,
    the mother of ice and frost?
    You don’t for a minute imagine
    these marvels of weather just happen, do you?
    31-33 “Can you catch the eye of the beautiful Pleiades sisters,
    or distract Orion from his hunt?
    Can you get Venus to look your way,
    or get the Great Bear and her cubs to come out and play?
    Do you know the first thing about the sky’s constellations
    and how they affect things on Earth?
    34-35 “Can you get the attention of the clouds,
    and commission a shower of rain?
    Can you take charge of the lightning bolts
    and have them report to you for orders?
    What Do You Have to Say for Yourself?
    36-38 “Who do you think gave weather-wisdom to the ibis,
    and storm-savvy to the rooster?
    Does anyone know enough to number all the clouds
    or tip over the rain barrels of heaven
    When the earth is cracked and dry,
    the ground baked hard as a brick?
    39-41 “Can you teach the lioness to stalk her prey
    and satisfy the appetite of her cubs
    As they crouch in their den,
    waiting hungrily in their cave?
    And who sets out food for the ravens
    when their young cry to God,
    fluttering about because they have no food?”

If you ask that particular Man who have done these calculations to explain how he Imagines Space, Time and Gravitational Effect, because that's what it's all about, I believe you will get a rather unexpected answer, but probably the most close one to the Reality of the Cosmos.

    • @levigoldwing1536
      @levigoldwing1536 4 года назад +4

      Any particular energy, particle or otherwise is stripped of it's information . Regarding quantum entanglement, it is believed through the containment of information that the particle is always present in the black hole including it's entangled particle should it be within the Schwarzchild Radius, or Beyond the Event Horizon. Since no energy is known to escape any black holes in our known universe, it is forever encapsulated within the black hole. Moreover, in theory, entangled particles will release energy in the form of Hawking Radiation. Note that energy cannot be created nor destroyed. This is important because it implies that in some form energy absorbed by a black hole should in theory be released. Quantum Physics is more Grey then Black or White. There is more we don't know in the quantum world then anything else. Essential Particles, Quarks and Neutrinos in theory and in experiments violate the Laws of Physics.

    I'm skeptical about his scenario in which 2 people have different times on their watches because they have traveled at different rates. Traveling is only done relative to other objects. If someone travels at the speed of light relative to someone else, the person he is traveling at the speed of light relative to is traveling at the speed of light relative to him. Wouldn't their perception of time be identical?

    What keeps planets moving?Gravity only pulls.

    • @StaticBlaster
      @StaticBlaster 4 года назад +1

      This is explained by Einstein's theory of GR. Gravity does not pull like Newton thought. Rather, the mass of the sun and all objects in space "warps" the space-time "fabric" such that smaller mass objects move around the larger objects. They technically move around the center of mass which is concentrated at the Sun but the sun does kind of wobble due to the other planets' presence. Space pushes mass. Think of it that way instead. So space is pushing on us. That's why we are stuck on Earth's surface. In fact, gravity may not be a force after all. It may be an emergent property of space itself when mass is "warping" it. Also, it may be that gravity is just an illusion. This is a pretty wild speculation but it's a byproduct of black hole physics and what happens to information around the event horizon. If you want more information, look up the holographic principle.

    • @albertdumont4977
      @albertdumont4977 Год назад

      Planets are moving because they are made of stardust that was already moving before they formed the planets themselves. Gravity helped to give them form by accretion. As there was nothing to stop them, they kept moving so far, but not in straight line across the space. The same gravity that gave them shape, keeps the planets moving around the stars. Yes, gravity only pulls, but it doesn't eliminates the initial force given to the planets, otherwise, they all would fall on their own stars of their solar systems. Two forces imbalances each other producing a circular effect.
