One of the things I miss most about being on a submarine was when we would occasionally pop up in the middle of the Pacific far away from any land or civilization and if it was at night you could go topside into the sail and look up at the night sky and it was just awe inspiring what you could see. It wasn't like a dark night in the city or even in typical rural areas. There was no light coming from anywhere for hundreds of miles so the sky was just completely lit up with stars and you could see the dust of the Milky Way spread across the sky. I would go up there and just stare. Just imagine, our ancient ancestors saw that every night because there used to be no light "pollution". It's really an incredible view. I think everyone should find a place you can go see it far away from city lights. It's one of the most beautiful things you can see on this Earth.
im lucky enough to live up the top of a hill covered in woodland. there's many a night when im walking in the dark, looking upwards and I think the same. I'm sure it gave the people back then a much greater connection to everything when you're seeing the true majesty of the universe.
Such a view appeared only once to me, when my wife and I visited Stewart Island, at the southern point of New Zealand. We actually embarked upon an excursion to witness the kiwi birds on a deserted shore, when they would start to forage on the beach. We were not allowed to use any flashlights, so as not to disturb the wingless birds. A side effect of these conditions was that we could see the night's sky, devoid of any light pollution. For me as a European, seeing the Southern sky is all the more exciting, but under these almost perfect conditions, it was indescribable. I need to revisit New Zealand, only for that purpose (the kiwis were fine, but hardly recognizable in the dead of night).
One night many years ago I was at a birthday celebration at a pub in a town in regional Victoria, about 2 hours outside of Melbourne, Australia. It was after midnight and I was standing outside on the main street talking to some people and then all of a sudden the whole towns power went out. A lot of people came outside and everyone was talking and curious about why the lights all went out. It took me a minute or two for my eyes to adjust but I looked up and the entire Milky Way was stretching across the sky. I told my friend to look up, and before long there were about 8 or 10 people all just standing there staring up not talking. It's absolutely breathtaking.
I have never seen anyone go so in depth into how many different varying stars there are. This is beautiful and I do thank you kindly. You have earned a subscriber tonight
This is absurd...how can a channel like this have less than 4k subscribers? As an avid follower of space time, Anton Petrov, Cool Worlds ect, this channel is right up there! Absolutely amazing! ❤ this!

If you chipped off a fragment of a Neutron Star, it would instantly explode with extraordinary energy from its staggeringly high internal pressure. It's only the gravity from their tremendous mass that keeps them stable - especially with their rapid rotations (which would rip apart pretty much any other material through internal stresses).
Thanks for not using the "only a sugar cube or teaspoonful of neutron star matter would weigh kghjillion tons and release the same amount of energy as khgjblillion Hiroshima bombs"
I really like your style. Between what you know and your expression of it into memorable, repeatable points of fact and relativity, is a high quality that I respect and appreciate a great deal. Keep up the great work! And thank you.
Your content is great. So chill, informative, interesting. You need more followers, your channel should grow fast. Doing what I can, keep making these awesome videos!
What a fantastic lil nugget of scale to include, about the neutron star. I've never read/heard before what the escape velocity would be of such a massive object. Half the speed of light? Geezus, that's enormous.
Just some update: the heaviest neutron star observed carries around 2.35 Solar Masses, was observed in the summer of 2022, so it is rather recent news.
I did well saving the best for last. I not only got my journey through the universe, I learned about stars I’ve never heard of! Nicely done, blue dot dweller. 🌌
Surprisingly, I did learn something new. I had never heard of this planck star before. That is a very cool Hypothesis. Definitely worth a subscription, thank you.
This is so awesome! I can tell you have great passion for the cosmos. Your voice and the way you talk about this is the only singularity I am thinking about I must confess. 😊😂
I really enjoyed your video. You have a lovely style of communication and you really put your own unique spin on the video compared to other UA-camrs in this space. New subscriber! Looking forward to watching more soon. Cheers.
I've always been into science, and nothing I've heard here is wrong, it's spot on, and it matches everything I know about this subject, so well done. Anyway, over all I found this video well presented, it explained things in an easy-to-understand way which made the video very interesting.
I love your name it's like that voyager look back from Saturn... Since then we're pretty sure we're small in the universe. I like to think of earth as a flaming mud ball. On a scale everything's a little earthy/wet or steam run off on a teeetanic scale lol. Love your channel just found it and subscribed ❤
So is there something like an event horizon around a Planck star? An area where the time dilation is not visible/affected? Also, near the Planck star, has it already exploded? Will the Planck stars explode after the last black hole evaporates? Does this mean that all of the matter drawn in will be released in the explosion? Subscribed. Also, also, your eye make-up is excellent/beautiful.
Planck stars should probably be indistinguishable from black holes from our outside point of view. As @bluedotdweller said, it apparently rebounds in an instant from 'its' point of view, but because of the extreme time dilation, we see it exploding after trillions of years. Its the same as an infalling astronaut (into a black hole) whose radio signals and light get weaker and weaker and right at the event horizon, a final, faint 'image' is 'frozen' in place, but from the astronaut's point of view, local time seems normal as he crosses the event horizon. If Planck stars exist (and we're probably a long way from ever finding out if they exist), then black holes don't. They essentially 'prevent' a black hole from ever forming.
They come from a neutron's quarks. Despite the fact that neutrons have no electric charge, the quarks do, and their movement creates a small but measurable magnetic dipole on the neutron.
Hail bluedotdweller! Nice video. Would it be a better characterization to just call black holes planck stars? The universe has a smallest unit of space & time. The gravity of a Planck star could create an event horizon. Also, it would get rid of the infinities in the equations, would it not?
Thinking of a black hole as a ultra nova star exploding so slowly that we cannot even perceived it, really gives an idea of the scale of time and space. Because of the Event Horizon, we couldn't even see what is happening inside anyway.
Hello, I’m sorry and mean no disrespect to correct something inaccurate and/or misleading in this amazing video. The map of the city shown in the background to give an idea of the size of a neutron star is actually Montreal and not New York.
Awesome work! Have you ever imagined how the collapsing core of a massive star might go through every phase of matter you've described here for the briefest of moments on it's way to becoming a black hole? Surely the collapse happens extremely quickly, but we know for example that extreme spin rates can potentially delay the collapse into a singularity due to the massive angular momentum involved. I like to imagine that even if only for the briefest moments of time, the collapsing core goes through being a white dwarf, a neutron star, a quark star, a strange star, etc. during its collapse. Since I'm obsessed with magnetars, l sometimes wonder if perhaps the most powerful magnetic fields in existence might potentially pop up during this process but for too short a time to be measured.
I imagine this is something that could happen! But like you said, stellar collapse might go too quickly for any instrument to be able to detect each separate phase. Maybe if a supernova happens close enough to Earth, who knows what we'll find. There's still so many mysteries out there.
@bluedotdweller The mysteries are what keep it so fascinating! I truly would never want to know everything. It would be really interesting to know how fast these massive star cores actually collapse. It's widely reported that when fusion energy pressure stops, the outer layers of the star collapse inward at about 25 percent of the speed of light until they bounce off the core due to the massive neutrino energy release, which creates the supernova. But I've never heard anything about how fast the core actually collapses beyond this point. That would be something very interesting to research.
Excellent as always, I've nearly seen all of them now. It's almost like hydrogen was designed to be the ultimate building blocks. With its single electron in its ring and the electrical imbalance that goes with it, it must crave contact like nothing else.
Saw your twitter comment about it being hard to stand out on UA-cam. Well, your video just got recommended to me after watching ParalaxNick and i was really surprised because I don’t remember the last time UA-cam recommended a small channel to me. So maybe that’s a good sign of things to come.
As red dwarves start to collapse into white dwarves, would that trigger a new phase of fusion with its heavier elements, causing the star to re-expand before it collapsed again?
Those glasses charm the pulchritude of your alabaster face with your Venus like nose. The countenance beneath your visage betray's the beauty of intelligant formidabilité !
Never heard of electrowrak burning before. Fascinating. The explosion of a plank star sounds like a big bang. I wonder if it would drag a universe worth ofmass from vacuum fluctuations with it. Surly, by the time it decayed, time dilation being what it is, the reat of the previous universe would be so far beyond the hubble horizon that it wouldnt disturb much... interesting.... i wonder if the physics of what little matter surrounding such an explosion would "bleed into" the resulting big bang. (Assuming thats a good parallel.) Truely fascinating. Thank you.
Looks like it's only me but I find this hard to swallow, and here's why: "Size" of a neutron (under quotes, because, for a quantum object, size is not strictly defined) is somewhere between 10^-14 m and 10^-15 m. For quarks we don't know exactly but we estimate the upper limit to be about 10^-16 m. So, in the instance of neutron degeneracy pressure giving way, we would expect immediate contraction of the neutron star's core by a factor of at least 10.000, possibly million, not much unlike the core collapse that causes type II supernova, and we should be able to detect it, and it should be quite distinct from the neutron star collision, as it would lack the very distinct oscillatory and "ringdown" patterns in gravity waves.
With living in a city, the experience of a truly dark sky is too much of a wonder for my little brain. I, laterally, get starstruck when I go on holiday to countries that have areas of no infrastructure or developments and witness such an awsome sight of a dark, unpolluted sky!!
Something doesn't make sense. If neutron stars really are atoms that have been compressed to the point that protons and electrons fuse into neutrons, a magnetic field is produced by moving electrical charges, and neutrons are electrically and thus magnetically neutral, how does the magnetic field get stronger? If there's nothing to conduct or propel electrical charges, how is a magnetic field sustained or enhanced?
Ah... Ok... Just an observation ~ Just how is it, you go from (7:13) the statement "because space expands and most things are moving away from us ~ eventually there will be no more other galaxies and clusters visible to us..." ~ to them say at (7:25) "all galaxies in our local group will merge" ~ Euh, just a slight touch of contradiction there... And yes, I fully understand that this is all within the realm of future speculation ~ but I would point out ~ while we are still learning about the movements and mechanics of celestial bodies ~ for the most part ~ it's essentially a huge perpetual motion machine ~ sure, the stars and planets have lifecycles, but the Universe as a whole is constant loop of those cycles! We know this because each Element of Matter on our planet was once formed by the gravitational fission of many different Stars... Currently the belief is that every piece of matter, came to be, from the overlapping blasts of hundreds of Supernovas (one for each Element, at the very least) that after slowing down, the mass of material they ejected then under went the affects of gravity which then formed into our Star and Planet... Why after millions of eons ~ would you believe this system would or could stop? Because you should not use the fate of a star or even a galaxy of stars to draw a conclusion about the fate of the Universe... Like what happens if space is moving, but it's in a rotation (like a Planet around a Solar System, and then the Solar System around a Galaxy, how farfetch'd could it be to think a Galaxy's that's spinning has an orbit too! Or that a whole Universe has an orbit! When we are essentially sitting within our own petri dish trying to gain perspective ~ we have a long way yet to go!
Could quark stars be disguised to us as black holes? High gravity, high radiation, high temperature, high luminosity. Maybe because of the extremity of their environments they are short lived, because their gravity attracts any nearby matter and the evolve into black holes? But to us, they appeared as black holes before they actually were?
Late to this one, but always look forward to your uploads. You are not only a great storyteller, but I trust the information you share with us. Cheers from Australia
The divide between Neutron objects and Black Holes interests me. Only gravity affects both and the 'snap' from one state to the other must be highly energetic before it disappears into its well. This moment has a chance of being revealing of dimensional fractures.
The Most common state of matter in the universe is plasma, blew me away. When you think of it, it is absolutely true and correct. I would like to know who would have the courage to dispute the indisputable?

There is no such thing as a "Planck star" even within loop quantum gravity. This is just made up nonsense.

How does a Planck star explode if it has to exceed lightspeed to climb out of the potential well?
I think you meant to say “matter could not be squeezed into anything smaller than the Planck volume” 20:01 - not Planck length.

Currently the belief is that every piece of matter, came to be, from the overlapping blasts of hundreds of Supernovas (one for each Element, at the very least) that after slowing down, the mass of material they ejected then under went the affects of gravity which then formed into our Star and Planet...
Why after millions of eons ~ would you believe this system would or could stop?
Because you should not use the fate of a star or even a galaxy of stars to draw a conclusion about the fate of the Universe...
Like what happens if space is moving, but it's in a rotation (like a Planet around a Solar System, and then the Solar System around a Galaxy, how farfetch'd could it be to think a Galaxy's that's spinning has an orbit too! Or that a whole Universe has an orbit!
When we are essentially sitting within our own petri dish trying to gain perspective ~ we have a long way yet to go!
Could quark stars be disguised to us as black holes? High gravity, high radiation, high temperature, high luminosity. Maybe because of the extremity of their environments they are short lived, because their gravity attracts any nearby matter and the evolve into black holes? But to us, they appeared as black holes before they actually were?
1:32 nice hook
Late to this one, but always look forward to your uploads. You are not only a great storyteller, but I trust the information you share with us. Cheers from Australia
something very soothing about your voice
Thanks!
Wow what a gem of a video. So dense!😏 Going to binge the channel now. Thanks!
Awesome channel
I like how when a neutron star is compared to a city the size of New York, the city shown is Montreal!
Awesome content
1st time viewer, regular viewer ❤❤❤
The divide between Neutron objects and Black Holes interests me. Only gravity affects both and the 'snap' from one state to the other must be highly energetic before it disappears into its well. This moment has a chance of being revealing of dimensional fractures.
The Most common state of matter in the universe is plasma, blew me away. When you think of it, it is absolutely true and correct. I would like to know who would have the courage to dispute the indisputable?
Thank you.
