I can't help but notice that at the galactic scale, the journey of the sun is so short-lived. If the galactic year is 230 million and the sun is roughly 5 billion year old, that means the sun is only at its 22nd orbit around the center of the galaxy. Given that the sun has 5 billion more years before turning into a white a dwarf, its whole journey as shining star would last 44 galactic years... assuming the sun doesn't run into another star in the next 5 billion years. Also, great episode and thank you for your hard work.

@cowlinator Год назад

@SolidSiren Год назад

Define short lived. How is the Sun's journey around the galaxy "short"? In distance? In time? It's neither, ultimately. You are taking HUGE journeys through massive amounts of distance and time and feeling that it is not so massive simply bc the number 22 is "small". Once you zoom back in and realize that 22 times journey is bigger than our brains can even properly imagine, it doesn't seem small. Don't forget, this is spacetime, not just space.

@CarlMahnke Год назад

I find it even more impressive that the whole milkyway has only turned like 60 times or so since its existence. You wonder how it could even arrange itself within so few rotations.

@NTH88307 Год назад

since our sol is a G-type star, that time of living is a bit average. let's not forget other O/A/B stars have such a shorter time to live. some even 'die' long before our star finish a galactic year, maybe just some several millions of years. however there are other stars live longer than ours (M/K) and there are hypothetical ways to 'improve' our star lifetime by 'extracting' a bit of our star's mass so it could burn out longer than 10 billion years. but this is another topic for another 'verse' =)))))

@@LtShifty Well I have known many experts/teachers who definitely did know the material very well but they seemed to refuse to explore new or better ways of breaking it down for their audience. They were very stuck in their one way of explaining or teaching the complex information, and if I couldn't immediately catch on with all the complexity and plethora of new terms and concepts then it was somehow my deficiency in their view. A very unfortunate and backwards attitude I've always thought.

I too was thinking about this a couple days ago. Thank you very much. That definitely helps me keep a mental image of our path through our universe. Now if I can just figure out if North is truly the top of our planet or if it's something that northern hemisphere folk came up with. Are we actually spinning in the different perspective? Do all stars spin in the same direction? Our Galaxy has a horizontal plane; do all star systems rotate accordingly to that? Does the universe have a horizontal plane. And of course no one expects you to memorize all the chemical formulas. Someone on your team should be responsible for fact checking that though. This is a science show. Should get the science correct. It's a little embarrassing and discrediting when you don't. Stop pouting, cheer up. Mistakes happen. No worries, we all still eagerly await the next knowledge you share with us. Just be amazed that some viewers are knowledgeable enough to notice things like that.

Gibberish PAL, here time to wake up. Regarding Spheres in Space 🌍and Comets: The on screen CGI showing spherical ball🌝🌍⚽objects floating in "Space" is pure nonsense. Our Sun and Moon are local ionizing gas plasma luminaries, travelling within the Tropics. Earth is a fixed level Plane of existence made of fossilized, mineralized biology of mainly ancient Titanic Dragons🐉 some thousands of miles long, turned to stone (Limestone, and Granite) 🗻mountains. The term is nucleophilic substitution, flesh to stone. The 38 Transition Metals we use today literally came from these titans veins, and arteries. The mega titanic fish 🐟🐠🐡give us most of the (SiO2) Silicon Dioxide, and (Si) Silica Dessert sands, exactly like the Sahara titan fish desert ! You still here ? 💫 lol. Space "rocks" ie. Asteroids, Meteors (meat🥩) and of course Comets, are the tough fossil remains of these titans (mostly dragons🐉🐲). The Void of space and level Earth was called the "Raqia" in ancient Hebrew (Latin-Firmament), and "the Expanse" is so massive we get Hyperbolic, and Interstellar (now) Comets. Due to Magnetic Force, when these massive transition metal (conductive) laden space fossils get near Earth's dipole, the Anode is discharging electrons into the "Comet" nucleus and taking protons from it. The Comet is now a hot cathode from a cold state (far away) and Sublimation-Phase Transition (from solid to a gaseous state) is causing it to discharge Carbonaceous Dust and microbes etc. by the hundreds of Tons an hour (example) as a Type2 Comet science.nasa.gov/science-news/science-at-nasa/2013/19apr_isonids above Earth. The 3600 yrs. ago Thera Eruption marked last cycle of energetic Comets, and it was called the "Shar" in ancient Sumerian, the "Completion of the Circuit". The electrical Shar is likely an intentionally induced 👽Cosmic Cycle, which adds raw material (Proton Density, Radial Velocity etc.) to the outer magnetic field of the Toroidal Vortex EMF above the level Earth. The "Solar Wind" is the measured strength of the EMF Torus (AKA magneto/heliopause) without it the harmful ionizing UVC radiation from the Void would make life on Earth impossible.

Amazing video, but quick question: Why at 4’30” in the video are the years of Jupiter and Saturn said to be 5 and 12 Earth years? It would be 12 and 30 (11.9 and 29.5) when looking at our solar system in the standard way. Is this just an error, or is there something else I am missing, like how often there is a conjunction or something like that?

Follow-up questions: In which direction does our CMB-relative velocity point? How much of that velocity is due to The Great Attractor and/or the Shapely cluster (what TGA is moving towards)? If we account for the motions due to Andromeda, TGA, and Shapley, do these add up to the CMB-relative velocity? If not... what accounts for the rest of it?

@samuela-aegisdottir Год назад

And what direction is the CMB-relative velocity regarding Earth's orbit around Sun and what direction regarding Sun's orbit around the galactic centre?

One thing I've always been curious about is how our star Sol relates to other bright stars in the night sky. I've seen maps of our local group, and local bubble, but then there's a jump to the full galaxy, showing the spiral arms and the sun's position, but usually not much more than that. How would a map of the intermediate scale appear? Where in the galaxy would we find other starts like Sirius, Rigel, or Betelgeuse? I saw a simple infographic of the constellation of Orion showing that the stars involved are actually not all that close to each other but it didn't show in what direction From the sun this was. Do maps like this exist? Using the reference frame of galactic north and south?

While a lot of stars and planets in the game are procedurally generated, Elite Dangerous really gives you a sense of scale, and the map does have stars in their appropriate locations within the galaxy, as far as we know. Players even claim 'space madness' when they're away from civilisation for too long, causing them to do things like fly into a black hole to see what happens. Another... Less a game and more of a simulator is Space Engine, but I've only used it once or twice so I can't speak to exactly how it works. I think you can do interesting stuff like create gravity wells and make galaxies collide though. Not sure. It's supposed to be entirely to scale though, and obviously doesn't only include the milky way. I imagine it could map stars like Betelgeuse for you. In Elite Dangerous though, you can actually fly to it. Really gives you a sense of galactic scale jumping instantly from star to star for months at a time to get from one side of the galaxy to another. Even with instant travel over 100LY, travel takes a LONG time.

@itcamefromthedeep Год назад

A program called Starry Night has a catalog of stars & stuff, and lets you see what the sky would look like from various places on Earth at different times, as well as corresponding starscapes from other objects. As I recall it did let you freely look around the universe, so that program could give you a sense of the stellar neighborhood. Stellarium looks like a free cousin of Starry Night, but I haven't fired it up yet.

@disnotesfoyou Год назад

Regarding frames of reference: if you want to travel in time, you have to know where the earth is going to be when you reach your destination. You also need to know which direction it’s moving. So far we have motion on the solar system, motion through the galaxy, and our galaxy’s motion, plus, I believe, a local galactic cluster motion. Still, to be safe, if I were traveling backwards in time, I would do it in a spaceship in case I didn’t end up where I expected.

I read "Dragons Egg" over thirty years ago and what struck me about this novel was the breadth of plausible possibility in the mind of the author. Despite the super-gravity of the neutron star , life still found a way .(eyes on tiny stalks, if memory serves); among which ,in a societal aspect , only the afflicted were able to perceive a "spiritual" phenomena albeit in the form of observing scanners ,wielded by none other than us humans , (physicists may wax lyrical on this theme re: mere observation skews the result) ...in orbit around the home of these creatures, whose evolution entailed a "mad dash" to grow to the great height of a few millimetres, whereupon they'd crystallize,(die) and spawn the next generation. A great sci-fi novel encompassing many disciplines and even has a crack at the religious instinct also. Fine vid , btw. Good work.

Great presentation! In regards to the chemistry with Silicon, I thought I'd add that we assume Oxygen and water - but if we use other hydrides, such as Ammonia, or NH3-H2O eutectic, or some other "semi-universal" solvent that is potentially reducing, (CS2 even?) and you might have a new chemistry for life. We still have a lot of chemical learning to do as a species. Look at the Olivine reactions generating CH4... our planet and conditions only allow a fraction of the possibilities in the universe. Look at the synthesis of small organics in gas clouds and dark nebulae? So, who knows. Might even be a hybrid of C and Si, or similar elements for life out there! And nano-particulate reactions could substitute for some standard enzymatic systems, potentially as well. Either way, I think we need to broaden our perspective, tempered with possible chemistries to truly find life out there. But carbon-based systems is the best place to start to be sure. Life seemingly finds a way. Darren H

Here is something I think you should consider. I don't know if you have done anything like this, or experienced it, but years ago I put a vinyl record on a fan motor spindle. It would work more safely with a piece of canvas or shower curtain. If you perturb the edge or anywhere while at speed, the perturbation will remain, even after your finger is removed. I believe this relates to the ball chain from the jar experiment and probably has a name already. Anyway, the dent or flexture remains, not only in dimension of size and shape, but fixed relative to directions in space and from the spindle. Even with the considerable centrifugal force trying to remove it. I am one hundred percent certain that this effect occurs in galaxies as well. It may have a relationship to what is called dark matter, in that this effect may be partially responsible for the observed inconsistencies.
