Primordial Stars

  • Published on: 08 October 2020
  • The Universe is ancient, far older than our own Solar System. What were the first stars that formed like? How different to the Sun could they have been? Today we explore 3 fascinating astrophysical stars in the early Universe.

    Professor/Dr. Kipping, i constantly come back and re-watch all your videos, it's the only channel that fulfils my itch for knowledge on all things Space, you're the BEST, thank you for your hard work so we can benefit and learn from it, very much appreciated.

    I like the fact that Prof. Kipping related the Primordial Stars to the Light in Lord of the Ring.

  • Axiological Cryptanalyst

    If stars are metal factoriesIf metals increase with time as a simple rule that can be turned into an equation (assuming no significant counter process)And Life is dependent on metalsThen it seems that this rule should be factor added to every 'probability of life' calc.I wonder if any papers have been written that accounts for (1) the amount of metals required by life (AWKI) (2) how the ratio of metals changes with time and (3) how that effects the probability of life in the universe.

    Boring to listen one more time about the Big Bang with so confident authority that seems that nobody has ever the possibility of to think by himself. Dear Sir, to state, in that way you do, about the beginning of the universe you MUST make the same magic that all physicists do: forget for a while (just in that beginning... 😜) ALL laws of physics. If you are allowed to do so, why not consider also God as a possibility?Both are wrong. For sure.Once this is stated, I do like very much your videos.

    I wonder if pair instability supernovas can fracture spacetime on some level like subspace tears in star trek. Is there any evidence of fractures or conjecture that space time can be fractured in a way beyond black holes?

    Brilliant, you answered a lot of the questions I had, such as where did the Sun get those metals.

    The Cool Worlds series of astronomy videos are unbelievably rewarding; they easily surpass anything else on YouTube in the sciences, and the competition has really heated up amongst credible, intelligent presentations in both the sciences and humanities. We have to thank Dr. David Kipping and his lab associates for the intellectual depth of their work and for his ability to explicate that work so compellingly. Wow—I will never again waste my time on channels with poorly edited writing that relied on secondary or tertiary sources, mispronounced Greco-Latin terms, used iffy academic methodology or revealed an unconvincing grasp of the principles under discussion. Why not hear science from a primary source, from a frequently published lead investigator? We who love science could be the beneficiaries of three different golden ages: * the digital revolution in communication devices, social interfacing, information theory, computer coding, microcircuitry, DNA computing, memory compression and AI;* the explosion of technology in the life sciences, including medical imaging, molecular drug development, deep ecology, habitat complexity, intersectional anthropology, paleopsychology and urban socio-geography, linguistics, theory of mind philosophies and consciousness research; * another explosion in the earth sciences, including metrics, imaging technologies, innovation in materiels, especially alloys, energy web balkanization, smart housing construction, smart rapid transit, baro-technology, femtosecond lasers, quantum- and nano-engineering, unified field theories, and, of course, the work we so love now—on exo-planets, exo-moons, large orbiting telescopes and collaborative space-station astronomy. The ideal would be regular, engaging, well-composed news from highly regarded masters of their disciplines from all those worlds. The ideal ideal is here—and is what thrills us from Prof. Kipping and his Cool Worlds staff.
