It just fascinates me to think that in addition to all of the gas and dust and stars, the universe (or at least each galaxy) is likely littered with jettisoned planetary and smaller mass bodies-so many with nearly unimaginable spans of nothingness in between.

Fraser, hi! Patreon member here. Just a tiny little question for you. I'm wondering if you could explain in more detail just how heavier elements are created in supernovae and neutron star collisions AND how those elements make their way from these cataclysmic events, through a phase of being dispersed in "gas and dust" (whatever these are exactly) until they finally show up in more consolidated formations in planets. For example, if Earth's gold was created in, say, a neutron star collision, can you describe its journey to middle Earth? Did the gold molecules travel from the neutron star collision in a consolidated fashion? Or were the molecules widely dispersed and then reconsolidated as the molten Earth distributed the elements according to their mass/weight?

Q: Science says objects can't go faster than the speed of light, but what about objects relative to each other? If object #1 is travelling 90% the speed of light heading due east and object #2 is travelling 90% the speed of light heading due west, when they pass each other, won't object #1 look out the window and see object #2 travelling towards it at 180% the speed of light? What would this look like? Would it even be visible? I'm about 90% sure this is just me playing semantic word games, but the other 10% is like, "no wait, maybe this kinda sorta breaks the laws of physics. At least to the people on objects #1 and #2.

The black hole that forms before the collapse (not but nanoseconds before are needed) then eats anything that collapses on the event horizon, never to return. The core would need to have enough pressure from above, added to the amount of iron and other core components to begin the shift of the Schwarzschild radius outside of the core's radius, and that is all that is needed to initiate the collapse.

Hey Fraser love your videos. Here are some questions for you: 1) I've noticed that when there's a full moon people are more energised and restless. In the same vein as Foundation's pyschohistory - have any legitimate researchers looked into the effects moons have on people? ie. there's a reason why the word "lunatic" exists.. 2) What actual power does the IAU or any other organisation/government have for protecting our dark-skies commons? ie. curtailing BlueWalker3. 3) This is kind of an astronomy question: I've encountered more than a few climate change skeptics and can't help but feel this general trend is because people simply haven't seen the data. Could you do a single video which shows a straightforward and clear visualisation of Earth's data over time (temperature, CO2 level, sea level), in particular showing all the cycles on one graph starting with the longest timescale and smoothly zooming in to the current day. The aim is to show people: a) there are small high frequency perturbations overlaid on top of large long undulations, b) the majority of Earth's history has been in a 'jungle planet' greenhouse Earth state where alligators could live at the poles. ie. there's a big BIG difference between "greenhouse and icehouse Earth" vs "glacial and interglacial periods", people don't get this.. [..that Earth warming up may tip us out of not only the interglacial period but also the larger icehouse state]

About the discussion on earth being save for superNovae. How is that about type 1a supernovae (white dwarf and 'donor' star)? Could a white dwarf on the brink of its critical mass be relatively close to earth with a not too massive companion and we might have missed it? Or is that completely outruled by now by what we can know about the 'near' vicinity. So basically, what is the nearest white dwarf to earth we could have missed. (in general I find that an interesting question. Like nearest brown dwarf we could have missed, at what distance could we currently spot a (non gravitationally lensed) rogue jupiter and so on).

This question is so interesting that I can't help but answer so forgive me. But in this analogy I'd think that the Theory of Evolution would be the equivalent of aerodynamics and biochemistry is the engine. We understand Evolution fairly well, the biochemistry of life while pretty well understood in some areas is also just so infinitely complex that we are still making groundbreaking discoveries regularly. The materials here would be the specifics of how life originates and there we're at something of a stump, we have a pretty good general theory and some successful experiments but we still don't understand the specifics enough to really rule out the possibility of life on any planets other than the most obvious ones. Like Mercury almost definitely doesn't have life, Venus seems unlikely, Mars might have had in the past and it could possibly still have some, but a lot of the moons of gas giants seem promising. We just simply don't know enough to make hard predictions yet, life remains one of the greatest mysteries in the universe, it continually surprises with what it can endure so it is really hard to rule out anything that at the very least has an atmosphere and some water.

Hi Fraser! I have a question I’ve been thinking about for a while but can’t make heads or tails of, relating the the Three Body book series. *Spoiler alert for Death's End moving forward* What would happen if a black whole was flattened into two dimensions? The Remembrance of Earth's Past series is full of mind bending concepts, but one of the most spectacular is when the solar system is flattened from three dimensions into two. The description of all the celestial bodies in the solar system being flattened and resembling Van Gogh's Starry Night was an incredible sequence. One object that wasn't described in the flattening sequence however was the black whole that Wade shows Cheng Xin in the abandoned space city. I know it was an incredibly small black hole (I can't remember how small exactly, but let's say nano metres) but it got me thinking…what would happen if a substantial sized black hole were to encounter the dimensional flattening? Like Sagittarius A*. Considering the description of the planets and the Sun being flattened was so detailed, and the rule that all three dimensional objects are flattened down to the atomic level and laid out side-by-side (for want of a better description), would it unveil everything that has ever fallen into the black hole? Or would the singularity be too small still and ultimately reveal nothing?

Ok Fraser here is a question for you. If the expansion of the universe is redshifting light to longer wavelengths and longer wavelengths of light have less energy than shorter wavelengths where does the energy go? I’ve always learned that energy can not be created or destroyed but can only be transferred and transformed…

I am curious about black holes. How did they find them and what did you mean by the star still existed but it was just in a black hole. How can a black hole exist?

I want to know more about man made radio sphere protection. Articles came out around 2017 about it.

Did you ever break a thermometer and see how the mercury comes together? Did it happen to you that in the end, you have two little balls left?... There you have your JUMBO's!

Question for the question session. Could we manufacture a micro singularity? and keep it alive by feeding it matter? Like somewhere out in the Kuiper belt

The disappearing star story made me wonder....if an alien civilization wanted to "harvest" a star and extract everything useful from it, how might they do that? Could that make stars disappear like this one did?

Question: Could Mercury have been a hot Jupiter? Gas stripped away from interaction with sun and core left?

I've seen reports saying Mercury isn't such a "chthonian planet". I'm guessing there's something that doesn't match up.. perhaps not dense enough to be a gas giant core? Would definitely like to hear more details about why it couldn't be, if that's the case, and what a chthonian planet would actually look like.

Question for the show: can you summarize the investigations on whether primordial black holes could be responsible for dark matter ?

You using up all my high speed data at 1070p. My high speed data downloaded lots of data really fast before I could change it to 144p.

Question: If there were rogue planets between, say here and Proxima Centauri, would we be able to detect them with current technology? How would we do it, or what new tech would we need to be able to do it? Also do we have reason to think there would be as many rocky rogue planets (presumably that we just can't detect yet) as the bigger planets we are detecting?

Stars and galaxies form in strings along magnetic field lines. Matter spirals about the field lines just as cosmic particles follow the Earth's field lines. Matter comes together in a Z-pinch along rotating Birkeland Currents. False novas are probably collapses inteh space between positive and negative ions. It is an electrical phenomenon.

Question, If planets use an iron core to produce a magnetic field like a dynamo, and Stars use ionised plasma and do not use an iron core to produce a magnetic field using an iron core... what method of magnetic production does a brown dwarf use?

Question: Following your video regarding Dyson Spheres (DS)I have been pondering this so I really hope you will see and answer this question. In conversations regarding DS, it seems we always skip to the end game of an advanced civilisation with a Dyson. Is it at all possible that an advanced civilisation not at the star DS level yet would first: A. Put their energy harvesters (pardon the terminology) in the gravity of a planet closer to their star first and perhaps build a wall of “energy harvesters” facing the sun where a star is tidally locked or a DS around said planet if the planet is not tidally locked. B. Put energy harvesters in the gravity of their stars, perhaps building wall like structures of energy harvesters facing their star. C. Build a DS or energy harvester walls around their own planet. If any of the above is plausible. Would James Webb be able to detect any techno signatures from these produced by these civilisations?

We've already started building our Dyson swarm. Think about satellites with solar panels. Imagine we keep going until we've either harvested all the energy from the Sun or we've run out of need. Yes, an infrared telescope like JWST is the perfect tool to search for Dyson spheres. Both complete and under construction.

Its a good thing that super novea happened in close proximity to the earth 🌎 otherwise we wouldn't have a lot of the elements we need and have.... 🫥 Hypernovea included or no gold and other stuffs.

I would like your take on if we could use a warp drive equipped ship to travel into a black hole. The ship creating a inverse space warp to the black holes there by canceling out the gravitational effects
