    ❤️thank you and appreciate
    If we want to know and understand things, we have to ask person who made it.

    If we want to understand this universe, we have to ask the One who created it!

    We can researching and sturdy about universe but we will never understand about it if we not become as they are. The Master of all will let us know if we humble, obey and ask Him.

    I think it would be cool to see the very first episode of Nova. How about it Nova PBS Official?

  • @outdoorfun8780 on May 29, 2024

    These people are so full of nonsense it is laughable.

  • @honodle7219 on May 29, 2024

    Every question we can answer raises three more we can't. From the day the first early human stumbled out of the forest, saw the moon, and threw rocks at it, never will we cease trying to understand the cosmos.

    The biggest energy in the Universe is…
    Nothing.
    Ok.
    Thanks, science guy.
    Keep naming things that you can't quantify.
    Nobody has done that.!.
    Forever and since mankind evolved enough to question nature.
    Good job.

    The universe is an illusion created by our brains. Once we die, there’s no universe. It disappears

    So if dark matter is keeping the planets from launching out from the arms of the galaxies like they stated then why doesn’t DM keep the universe from expanding from the Big Bang? And is it expand from earth like in video? Something doesn’t add up.

  • @customerreview6783 on May 29, 2024

    Woke DEI episode. Nova like most PBS is garbage now. Had to turn it off. Unwatchable. Definitely an emphasis on women scientists.

  • @thorenshammer on May 29, 2024

    When Voyager One and Two were launched, I was a sophomore in high school, so I remember all of the excitement and wonder of the "Grand Tour" of the outer Planets. We, as a scientific community, are just scratching the surface of space, as the James Webb telescope is literally re-writing the textbooks.

    Why such is there so much background music? I find it annoying and it takes away from the scientific content of the program.

  • @ChickSage on May 30, 2024

    I wonder how many rogue planets and black holes are whizzing around out there.

  • @Zurround on May 30, 2024

    I usually sleep through vids like this but I was awake dang.

  • @user-mi9rl7eu9h on May 30, 2024

    Yes we are the center of the multiverse because every point in space is the center.
    We learn than in basic cosmology.
    I'm tired of fake cosmologists who forget that fact.

  • @NashPotatoesOutdoorShow on May 30, 2024

    You know how some particles behave differently when we observe them. Maybe the galaxies in the Universe only exist now that we're able to view them with these high-powered telescopes…

  • @philosothink on May 31, 2024

    I have held the belief for over two decades that our "Big Bang" was nothing more than a local event caused by the collision of two supermassive black holes, or something bigger we haven't defined. When Dark Matter became a talking point, It dawned upon me that this much older, "Real Universe" is likely more dense and exponentially larger and older than we've imagined, because of gravity and time. I believe the collision released "primordial matter" back into a pocket of this ancient, much larger Universe. Our Universe is just ghostly matter to whatever lives out there. A puff of light in the darkness.

    Contemplating the increasing rate of "the Universe's" expansion led me on this thought experiment. I believe that if the Outer, Dark Matter Universe if you will, surrounds us in 360' and is "dark matter heavy" while our side is more light matter, then gravity will "work backwards" and cause an increasing expansion of our Universe, as it's reabsorbed by the bigger, older one.

  • @all2031 on May 31, 2024

    Dark matter/energy might be matter not gone through the Higgs Boson field. At quantum level, it tries to go through the Higgs's Field and becomes visible for a moment as energy field then disappears because somehow, Higgs Field stops it. Our universe lies inside of the dark matter. We see its effect as an expanding universe. The visible matter may have been dark matter before it could pass through the Higgs Field which may have been less energetics in the beginning due to intense heat and pressure in denser beyond plasma hot time/space continuum. It might be anti-matter/anti-gravity. Higgs Filed is keeping it separate from the visible matter.
    Black Holes are portals into dark matter/energy, possibly.
    The mismatch between the Hubble constant using inside in and out methods of calculations is due to the mismatch of cosmic pressure inside our universe our side of Higgs Boson and the invisible dark matter/energy

  • @nobullman5853 on May 31, 2024

    Do you suppose the DeviL has a brain ? We know a brain is required for thought process in this world. A I rummaging ones and zeroes is not a thought process

  • @buckanderson3520 on May 31, 2024

    Another interesting observation is that the universe is expanding at the same time our knowledge of it does. Our knowledge accelerates so does the universe. The two can't be related can they, 'cause that would crazy right…righT….rigHT…..riGHT……rIGHT…….RIGHT???

  • @sidewinder814u on May 31, 2024

    Wrong! An infinite number of galaxies in the infinite universe!

  • @thomasperri5316 on May 31, 2024

    Who's going to be around trillions of years from now to witness the end?

  • @Velereonics on May 31, 2024

    dark matter is the story of how a bunch of egomaniacs got really obsessed with magic because they didnt have the full picture.

    you dummies dont even know what produces gravity and you think you are sure about all this? laughable.

  • @deepdusto on May 31, 2024

    I can't find a SINGLE resource that coherently depicts the cosmos, all this junk of Galaxies, Milky way, dead star, alive star, white purple black dwarfs, whatever. There is not a SINGLE coherent picture that helps to understand. What has happened to our science, it has become a boatload of non-working spaghetti.

  • @leoborganelli on June 1, 2024

    Will be vewy cold and vewy dark…

  • @un-Lawyer on June 1, 2024

    Been a Nova fan all my life but it's getting to feel like the entire things is the hype up you usually get in the first few minutes.

  • @Urine_Urine_Urine on June 1, 2024

    My favorite days in school were when the science teacher would wheel in the giant TV and put in a Nova VHS tape.

  • @RandomTChance on June 1, 2024

    If hidden mass doesn't account for holding galaxies together does a spiritual answer hold sway? 🕊️🙏🕊️

  • @teronward7570 on June 1, 2024

    So they made up a whole new matter who know one can see and we just believe it. The smartest people always say I have know idea why but this is the reason without a proof. I don't believe dark matter until they prove it. This is Santa Clause science.🤣🤣

  • @ronaldkemp3952 on June 1, 2024

    Dark matter is an artifact of the unknown. Astronomers can't explain why stars along the outskirts of galaxies, extremely far from the barycenter of the galaxy's mass is orbiting the galaxy at more than a million miles per hour. At 60,000 light years from the central black hole the stars, like the orbit of Pluto should be quite slow. But instead stars increase in velocity instead of decreasing in velocity with distance from the center. Thus dark matter is a term used to explain the motion, even when the hypothetical dark matter can't be measured or observed. Because it can't be observed and measured directly they postulate dark matter doesn't absorb, reflect or radiate energy. It doesn't decay and doesn't produce any thermal energy. The only effect this hypothetical thing has is the unexplained accelerated orbits of the stars as they get further away from the galaxy center. So they came up with the idea of a dark matter halo surrounding galaxies.

    Dark energy is an artifact of the unknown too. Astronomers first couldn't explain why galaxies move away from each other instead of their gravity pulling them closer. So they came up with the big bang after Edwin Hubble noticed distant galaxies to be producing a redshift in the light, indicating they were moving away from us. If they produced a blueshift in their light they would be moving towards us. Then Hubble realized the galaxies furthest away had higher redshifts than the galaxies nearby. Thus determining the accelerated expansion of space between us and the most distant galaxies, to which they've pinned on dark energy. It's some unknown force pushing galaxies away from each other beyond the effect of their mass and gravity.

    We know it takes energy to move mass against the effect of gravity, so they came up with the term dark energy. Dark because it refutes the laws of motion and theory of gravity, and energy because it takes energy to move mass against the effect of gravity.

    Dark matter is called dark because it too refutes the law of motion and theory of gravity. And we know it takes mass to produce gravity, causing matter to accelerate towards other matter in the vacuum of space. We also do not know why mass produces the effect of gravity. Thus why the extra motion of stars is pinned on dark matter. Dark because it refutes the laws of motion and theory of gravity and matter because matter produces motion via gravity. And it's called cold dark matter because it doesn't radiate heat or decay.

    Basically these artifacts prove the laws of motion and theory of gravity are wrong because they can't explain the motion of stars and galaxies.

  • @thomas7098 on June 1, 2024

    the dirty little secret is that none of these pinheads knows anything about the space out there!!! the only one who knows is the Creator and He says "you must be born again" Repent and receive His free gift of pardon, Maranatha!!

  • @TerryUniGeezerPeterson on June 1, 2024

    Thank God this "Cosmos" isn't narrated/hosted by NDT.

    I've decided

  • @MikeJones-wp2mw on June 2, 2024

    I think the actual solution is that light accelerates over vast distances. That's what the red shifting is, it's the uncoiling of the light wave like a spring releasing it's energy and flattening out. That's what we are misinterpreting as the galaxies furthest away accelerating away from us faster.

  • @edmill9159 on June 2, 2024

    Based on comments, I’m def gonna watch this 53 min vid 👍🏻

  • @ronaldpokatiloff5704 on June 2, 2024

    The universe movement is controlled by gravity coming from a computer connected to a three dimensional picture tube. The big bang is caused when the picture tube is activated?

  • @spiritsplice on June 2, 2024

    "our entire understanding of the universe was turned upside down"

    yet they still cling to nonsense like dark matter and the big bang.

    "often wrong, but never in doubt."

  • @bobjayp on June 2, 2024

    Don't think PBS quite met the DEI standards on this presentation. The minimum standard foblacks was met, and the standard for women was exceeded. But several groups were excluded.
