Just stay away from Relativity. It's flat earth science personified. A couple of things to understand. 1) the laws of physics are equally applicable in ALL frames of reference. Be they vertical, horizontal, curved, 3d, 2d or in.thr case of photons, 1d being the wavelength. 2) Space and Time are separate frames of reference. This notion that time slows down with acceleration in space is church dogma. Designed to get you to worship at the alter of relativity with its promise of youth and eternal life at the speed of light. 3) mass is not a force by itself. F=ma. Acceleration is the force multiplier. Acceleration is the actionable force. Acceleration is the correct frame of reference. Mars has nearly the same amount of acceleration as Earth. 1480 vs 1440 minutes to complete one rotation. Only a 3% difference. Gravity comes from acceleration, not mass and yet Mars gravity is on 38% that of Earth's. As you cam see, everything is pretty much a lie. They mask the errors in complicated math formulas to bamboozle you and make themselves look intelligent. They aren't. Unless they are outright scamming you. Is Becky scamming you with her black hole thesis? E=mc. The conversion of atomic energy to radiant energy via Acceleration. A black hole is nothing more than stored energy. High mass, low acceleration, low energy output celestial object. There is no accretion disk anymore than Saturn's rings are accretion disks. There is no falling into a black hole. It's deceleration. Being at the center of a rotating galaxy, that is where the least amount of acceleration in space is taking place. E=mc. No acceleration. No Energy output. No electromagnetic radiation in the visible light spectrum. Not as glamorous as black holes being monsters of the galaxy swallowing everything up, including light waves. Just ask Becky, if E=mc, how much acceleration does a black hole have. Why are black holes at the center of galaxies with the least amount of acceleration taking place. To learn the correct physics, the correct frame of reference is Acceleration. Not mass. F=ma/E=mc. Force comes from Acceleration. Mass comes from Acceleration.. How much gravity (force) Mars has comes from its Acceleration factor. Not its mass factor. Being wrong about Mars gravity lead to many probes crash landing on Mars because they got the acceleration factor wrong. Will Becky and her colleagues ever admit this to the public. Probably not as it would destroy the very foundation of the church of relativity. Mass attraction? That's flat earth science. Don't let them convince you otherwise.

I'm pretty sure Douglas Adams makes a nod of a joke about the naming convention of pop I-III stars in the Hitchhiker's Guide series when he reveals that Zaphod is Zaphod the first and his father and grandfather, be Zaphod II and III (resp.). So...yeah, funny, and weird enough to have appeared in pop sci-fi shortly after Pop III was first discovered.

Similar to pop-3 naming, that the charge that an electron happens to have was named negative by Ben Franklin was a similar historical accident that has made electrical engineering confusing ever since.

Not really. It was Franklin's notion that charge flows from + to - that makes electronegativity slightly confusing. But even that is fine _in most cases_ since current carriers of either polarity make just as much sense for current flow. This becomes clear in semiconductors, where they literally talk about positive charge movement as HOLES moving around. Also, electron mass is much smaller than proton mass, so protons being + and electrons being - is quite appropriate. With that larger mass, protons do not move around as easily, so even the symbol choice itself is appropriate there.

"Metal" in glassblowing means molten glass, and in roadbuilding means stones, both of which are not conductive chemical elements but compounds, such as silicon dioxide, or mixtures thereof. Astronomers and ordinary people agree that lithium and iron are metals, and as astrophysics doesn't care about the conductivity or ductility of elements at room temperature, I think that calling oxygen and carbon "metals" is fine in that context.

It's actually good luck that stars of decreasing "metallic" content are named with increasing numbers. Look what happened in thermodynamics, where a foundational zeroth law had to be inserted. Now, if ever we observe something that fuses hydrogen into helium yet is somehow even more primitive than population III stars - those will be population IV.

Ummm, no. Stars of all "populations" burn hydrogen to helium. I don't see why people get hung up on the naming of the "populations". The first population differentiated from just "stars" was population 2 - with everything else being population 1 ; historically the next population differentiated were population 3 ... and it could go further (but the window of both time and differentiation is closing, rapidly). The problem comes from people trying to impose an formation sequence onto a discovery sequence.

It sounds like stars are consciously trying to do that. May be they do it to make the point in a shorter time, but I think it will be much better for the people who do not know the process, to explain how it really happens.

Hi Becky. I listen to your podcasts and enjoy them. I'm a member of an astronomy club in Gloucester, ma. Listening to your explanation of population 3 vs. 2 vs. 1 stars and the inconsistancy made me think about the term reionization . I worked in the semiconductor industry where our machines made ions. When you say it was hot in the beginning and it cooled enough to reionize particles to become atoms that confused me more. I thought ions were made when electrons were removed from an atoms surroundings. The term "reionize" sounds like removing ions rather than putting them back. It should be deionize as in the atoms have required their electrons, making them atoms again. This term reionize might be another misuse of a term. 😅

The naming does make sense when you consider the order of discovery. Population 1 is the first population that were seen clearly and analyzed. Population 2 were the 2nd group we were able to analyze closely, so, naturally, this would be the 3rd population to be more closely looked at and that we're beginning to analyze.

For a hypothetical example, imagine that it is 1 billion years ago and we had the JWST and all our same knowledge back then. Do we know proportionally know how easier it would be to detect them given they would be closer in space and time to us? Maybe through that understanding we can get a better statistically relevant number, like what the odds of us being able to detect them given the universes current age and the distance of the galaxy and star we are analyzing so we could get a sense of how many ancient galaxies we would have to survey to get a probable chance of finding one

I think they'd still be pop-III stars b/c they would only have hydrogen and helium. One of the bits of evidence for the big bang is that you can do the math on the early universe and at one point it was all hydrogen ions (i.e. protons and electrons) with conditions similar to the core of a star - and you can calculate how long it was in that state and therefore what the ratio of hydrogen to helium would be, and you end up with the correct amount.

Something caused that plasma to cool down and condensing mass in the form of quarks, cause, maybe, by shock waves from the Big Bang, beginning the process that led to actual star formation. These proto stars would not be huge, like the gen 3 stars but small and many, like brown dwarfs, in the confined space of the first event.

On the subject of poor naming decisions that have stuck around, little compares to Franklin's accidental creation of "conventional" current flow. Everything in electronics is precisely backwards, and we really should just all agree that electrons are positive, not negative, and then we can keep conventional current markings on existing components (e.g. the 'negative' band on a diode) while not being wrong. We'd have to re-label batteries, I guess.

What are you talking about? We'd need to relabel everything with a + and -, and we'd also also have to rewrite all the rules about electricity and magnetism interact - since you have magnetic fields rotating counterclockwise around an electric current - if you switched negative and positive then you'd have to switch it to clockwise, which would melt people's brains and also require replacing every textbook and diagram about electromagnetism. And for basically no reason since protons CAN carry charge (for example in a proton on positive ion beam)

She just needs something _other_ than the omnidirectional mic (which naturally picks up all the room reverb) she’s using here, such as the lapel microphone she _used_ to use before the move. Perhaps it got lost in the move?

Them wedgy square things stuck on the wall may help. Ironically the new better mic probably makes the reverb more noticable. The blue wall is indeed very nice 🙂

Great vid Dr Becky! Thanks. Could you soon slot in an attempt at an explanation for your regular stars "need" to fuse faster or fuse heavier elements to "resist" gravity, like you repeated in this vid at 7:20, please? I wonder why old stars swell up and get hotter like the sun will apparently in future, it cannot be a need to resist the pull of gravity. Cheers!

While much is uncertain about these observations, what is certain is that you have piqued my interest in it. When the only two known options for these observations is the first ever stars in the universe or evidence of an early smbh growing, the only possible outcome is "Wow!!!"

Your new room looks good, lots of natural light. That does means the white balance is much higher K than your earlier videos and not so much of the fireside glow of the last place. The clip at 16.00 has it about right, the colour coming from the table light behind looks more natural and doesn’t have a green cast. It works better with a slight yellow to complement the blue wall. I’m not suggesting you go full Ridley Scott and give it the teal/orange of ‘Blade Runner’, but maybe switch the auto white balance on your camera to manual?

The population thing does really annoy me, but no wonder. In my professional field of computer networking, when establishing priorities for things we haven't been able to decide if bigger or lower numbers mean higher priorities. Thankfully which way round they are for each protocol is just a google search away.

Just a quick note. I finally decided to try Brilliant, but when I looked at there Terms & Conditions one thing I became aware of made me leave IMMEDIATLEY!! They have AUTOMATIC RENEWAL! Terrible, invasive idea, no way I will EVER sign up to ANYTHING that does that. Now if they change THAT, then I am up for it. To be frank, I really really did not expect them to be using that NASTY service option. Bad on you BRILLIANT. In FACT, that is NOT Brilliant at ALL!!

Pretty much everything that involves a monthly fee automatically renews... Do you use Spotify or similar music streaming service? Automatic renewal. Do you subscribe to Netflix or similar streaming service? Automatic renewal. Do you pay your mortgage or rent by direct debit, or similar bank transaction? Guess what? If you only want to pay for one month then it's entirely on you to cancel your subscription, etc, before it renews. That's the standard that literally everyone else uses.

Yes, the numbering of the stellar generations has bothered me since I learned how it works. But it does make sense from a scientific and empirical perspective. As observers whose observations are constantly improving due to advancing technology, humans started with what could be observed at the time... which will necessarily be what's closest to us in the cosmic timeline... so the stars we were first able to observe will logically be where we start counting.
