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.

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.

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. Some of the experts really put in the extra effort or are naturally gifted and can explain these things to the public and it's a breathe of fresh air to a curious mind to want to dig deeper into the subject.

@@ExxInferis Yep. That's why time-only travel is at least impractical, you would always end up in the vacuum of space. Space-time travel would be a solution, if only we could figure out a way to determine the absolute starting and ending position of the trip. A small error, very small, infinitesimal compared to the distance traveled by Earth, let's say 100m, would shoot you in the air or deep underground.

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.

Just wanted to thank you for all the knowledge spread. I always struggle trying picture how we are able to get a reference point at all from our location.
@dard1515 Жыл бұрын
These frames of reference remind me of the map projections regarding depictions of the Earth itself, that none can depict all of the information except for a globe but then you can't see the whole map at the same time. There's no single best frame of reference for all cases, as you said, in a way analogous to the map projections.

There's an error in the video at 4:30, since Jupiter and Saturn years are not 5 and 12 respectively, but around 11.9 and 29.5 respectively.
@millicentsmallpenny5837 2 ай бұрын
The 5 and 12 are actually about the distances from the sun expressed in AU, but not quite -- Saturn is more like 9.5 AU He kind of has a brain fart there. But he was pretty good

04:24 Did Matt just say that the "orbital periods of Jupiter and Saturn were 5 and 12 earth years, respectively???" He must've meant 12 and 29 years and we just misheard him ;) Also, why is the solar system in this video sometimes depicted from above the north pole (planets circling counter-clockwise) and other times from below the south pole (clockwise planetary orbits). Is that to prove that he's not a polar chauvinist? I'm sure being from Australia has something to do with this..

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?

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.

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.
