New Light on Old Stars in the Era of the James Webb Space Telescope
The chemical diversity of the universe that makes our own existence possible is owed to multiple generations of stars that converted the primordial soup of hydrogen and helium into the periodic table we know today.
To understand this process, postdoctoral researcher Roman Gerasimov looks for the oldest objects in our galaxy that formed shortly after the beginning of time and preserve the fossilized record of the early universe in their chemical composition.
The new generation of observatories, including the James Webb Space Telescope, now provide a deeper look into our cosmic history than ever before. In this talk, Roman invites you to join him in his search for the oldest stars in the least explored corners of our galaxy, and the chemical secrets they contain within.

    I think the link with global warming is pretty stretched. There has always been a worldwide temperature gradient. A degree or two of increased average temperature in certain areas is nothing compared with the temperature variations across the surface of the world from the poles to the equator. Selection is ALWAYS ocurring with populations existing on the edges of their respective ranges. This link between global warming and increased fungal disease in humans is an example of researchers massaging the truth to get published and funded. Claim that global warming is associated with something and people will pay attention. I'm just highly skeptical here. What's also happenned along with global warming is the increased use of anti-fungals. Dude even mentioned it. And the Chytrid fungus. It was probably caused by the introduction of invasive species of amphibians. Global warming though is the sexiest variable. This pisses me off because global warming is a real problem and damn the scientist who cries wolf now.

    I liken the inability to detect dark matter particles to the inability to detect the luminiferous aether of the late 1800s. DM can't be a field, as fields do not "clump," so it's gotta be a particle. But despite billions of dollars and decades of experimental research, nothing's been found. Proposing hypothetical particles (axions, the sterile neutrino, etc.) to explain another hypothetical particle (DM) seems to be the pinnacle of scientific ignorance and hubris, particularly when modifying Einstein's gravity theory remains open to consideration. .

      Sorry that I have not stopped in to answer questions for a long time. See my reply to a previous questioner asking about MOND below in partial response. Physicists attempt to find DM candidates which are possible to detect, but we also know that they might have properties that will never allow them to be detected on a particle-by-particle basis (eg particles which only interact with ordinary matter via gravity and not the weak nuclear force).

    How about this? Dark Energy is EQUAL to Energy plus TIME, for our purposes here, "HEAVY TIME." Mira, look, we see this electron orbit however many times a minute. We set that as our base reading, right? For our plain of existence, anyway. However, in these pockets of, "heavy time," that same electron now has readings of a billion times a minute because time is HEAVY here and passes a billion times faster. Or, energy where there shouldn't be energy / dark energy / Heavy Time. See, in that same minute to us, that electron aged a billion times faster and therefore has given off readings of dark energy. Dark energy IS "HEAVY TIME." It's the difference in TIME that we're seeing! Maybe. The light from these galaxies have been aged by going through pockets of dark energy or "heavy time." Numbers used for reference only. TI-I-I-IME IS ON MY SIDE! YES, IT IS! Now we look at the other side of the coin, dark matter. Pockets of dark matter are actually pockets of "LIGHT TIME." Mira, look, if heavy time is faster pockets of time. It stands to reason, light time would be slower pockets of time, right? Making our base electron seem to stand still. Get a pocket full of seemingly motionless nothing and you get a pocket of starving dark matter. In this case, "starving," or slower pockets in time is the same as creating a vacuum in space. Since this pocket of "Light time" is "starving" and everything outside this pocket of dark matter is in a "heavier time," it makes it appear dark matter is attracting when really it's just a vacuum, IN TIME, trying to equalize. Making it stand to reason, by my, "I'm not smart enough to give anything more than this simplified reasoning, that Dark Matter is "LIGHT TIME" and Dark Energy is "HEAVY TIME." Maybe. Now think about this. As light travels through the universe and passes through these pockets of Heavy Time or Light Time. Doesn't that "age" that particular beam of light? Doesn't that beam of light that is say 40 million light years away now look like it's 100 million light years away? If I'm right, it would explain why these 6 "old" galaxies are being discovered. Also, if I'm right and someone proves it, you must name it after me and give me a cut of the Nobel prize winnings. Pass it on please. and thank you. P.S. I may have gotten the names, LIGHT and HEAVY, backwards. Thanks again and don't worry. Where I come from, crazy is a compliment. ;-P

    Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city, with no interaction with each other until they used the subway, complain about the same time paradox unless it was effected by it? Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? Ti-i-i-ime, is on my side. Yes, it is.

    My idea so I get to name it! What I mean is, no one has claimed it so I'm officially calling, "dibs." Voyager 1 is now in Milky Way's interstellar time or "Mikey's Time." "V-ger's" message has sped up now that it's outside our suns time bubble or, "Terran Time." It will be faster still when "V-ger" sends a message from beyond the Milky Way's time bubble. (That name is still up for grabs.) Then there's Outside the Local Group time bubble, so on and so on until we get to the, "True Interstellar Time Standard." Now that "V-ger" is in interstellar space, it's also in the Milky Way's STANDARD, faster moving, interstellar time or "Mikey's Time." This can be proven by turning off everything except its clock and transmitter. Have "V-ger" read time for as long as possible. They WILL show the flow of time speeds up the further away you get from any celestial bodies. Until you reach the Milky Way's time standard or "Mikey's Time." •Our sun's time bubble: "Terran Time" we know and have measured. •Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring. Wild guess I'd say time will increase in speed, now and until V-ger is outside the Ort cloud .007-.07% faster, maybe. Just for reference. •Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08% to a couple seconds faster, maybe. Used just for reference. •Outside any influence in the, "True Interstellar Time Standard," or...;-P Name NOT up for grabs BUT just begging to be measured. The rate/flow of time is fastest here. (Time flows fastest here so it's best to have your motor boat.) ;-P A minute is a minute in all. It's the rate/flow I'm talking about. The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time." Pass it on, please and thank you!

      Sorry that I have not stopped in to answer questions for a long time. Um...I looked at minute 27. I was talking about the mass of neutrinos being exceedingly small, but did not compare to photons......Perhaps somewhere else I was referring to the effective size of fundamental particles ("cross-section" is the particle physics jargon), but even here, the effective size of a particle is not merely a property of the particle but also of the target particle and the relative energy of motion in the system, so I don't believe that said some blanket statement like "neutrinos are smaller than photons ". But please point out more precisely in time if I have not addressed your question.

    • @MrEnjoivolcom1

      The accretion disk around the black hole comes close, moving at near speeds of light. Thus the extreme heat of said disk/debris circling the event horizon of said black hole. Black holes do in fact sometimes eject jets of matter (from both ends, equally). These jets, often made of photons and gamma rays do travel at or near light speed.

      @iylevine Рік тому

      Sorry that I have not stopped in to answer questions for a long time. I don't believe I would have claimed FTL speeds for black holes. Only in one sense does this happen. Relativity does not allow matter to accelerate to or beyond light speed, but the universe is expanding and a distant enough galaxy would be moving away from us at speeds faster than the speed of light, but that is due to the growth of space between us, not the speed of matter through space. I hope this helps!

People who support the idea of MOND are certainly in that class. But MOND would only explain some of the observations, not all. They then need a different ad hoc explanation for the other observations. This does not mean that the DM hypothesis Is correct, but it is the simplest most expansive explanation of a much wider variety of observations and it can naturally arise from ideas to go beyond the standard model.
