I love how Reid introduces Reid. 😅
Yeah , I thought he may have a twin
Lol he should have said thank you Reid
@@amberwalsh5767 Yes, ge should have.
"Nice segway, Sam"
"Thanks, Sam"
And the look of disgust introducing Stephen 21:57
"Take it away, Reid!"
"Fascinating stuff, Reid!"
"Gosh, that guy's handsome!"
*Thank you, Reid.*
Thanks, Steve!
'The sun has been there every day of your life'
IM FROM SEATTLE I NEVER MET HER IN MY LIFE
😄
The black pfp sells this.. HAHA
Me too. I know what you mean😆🥁😆
Reid had so much fun introducing himself, I'm here for it dude 😂
"Speaking of hot, here's Reid ..." 🤣🤣🤣🤣🤣 man, those introductions were so funny, excellent job. Also, poor Stephan 🤣🤣😆😆
Find yourself a partner who looks at you the way Reid looks at Reid
This really is some of Reid's best work. The sarcastic eye roll and disdain as he announced Stefan killed me. 😂
Reid announcing Reid is so funny 😂😂😂 Reidception 😂😂😂
Lol - almost a jump-scare seeing Stefan show up after so many Reids
"well, here's.. Stephan, who can explain." C-C-C-COMBO BREAKER
SCIENCE: We can't find anyone else from that stellar nursery
THE SUN: ...and you never will 🌞🔪
All I need to know about the sun is that it is a deadly laser.
360°!
This Reid fellow really knows his stuff, and is darn handsome too!
I love Reid intro Reid too. For me the current Reid is the best version. Really dig that thick beard. Love watching Reid and the info is cool too. 😉
Reid introducing himself is like when I finish a night shift and start a day shift at the same place. 😂
yikes!
“Dating stars is really hard”
That sports guy Taylor Swift is with: “Can confirm”
🤣🤣🤣
This year (2024), I am so excited for X-Mas, because that is when we finally get data from the Parker Solar Probe! So get your glasses - it's getting bright and hot - and very cool! 😎
I thought Sci show hired Tyson fury for a second
Right 🤣
And sounds like Penn Jillette
Old beardy Reid introducing young less-beardy Reid is gold. 😂
The Reidception is real
Reid, you had fun with this one and I'm *here for it.*
Metallicity! New word to add to try and sound smart. Thanks, handsome Reid!
I live 1 mile from totality. So excited 🌞🌚
I know I spent four hours with that sun yesterday and the mfer already burned me...
Sun wearing the shades to block out all the haters 😎
I expect that Feynman didn't actually do the calculation. I think it is likely that he was asked the question and simply answered using intuition or a quick estimate. Possibly after he was asked and he answered, he later did the math. It would be quite uncharacteristic for him to make such a technical error in a detailed analysis.
thanks, quite the well rounded video
SCP-001
I find it very intriguing that both the size and distance of the moon are exactly like the sun's in an eclipse and that earth has life, this solar system is very rare and interesting.
We live at the right time for this :)
You mean to tell me I'm not the only one in the universe oh my God this is mind blowing
"Dating stars is hard"... tell me about it. All I ever got was restraining orders
Was it called gravity?
The implications of this aren't actually funny
tysm reid
Fun episode!!! 🎉
Travelled to see the total ecplipse in the UK in 99. Day before, beautiful clear skies. Day after, beautiful clear skies. Time of the event? Solid cloud as far as the eye could see 🤦♂️.
Hope this one has better conditions for those getting to see it 👍
It's important to keep Galactic mergers in mind, the Milky Way like Andromeda is actually a combination of multiple galaxies.
During these mergers the stars, planets and other bodies would have been drastically rearranged, making it very difficult if not impossible to pinpoint the exact origins of many of them.
Never heard this much about solar eclipse on RUclips until it happens over the US 🤷♂️
Also US does this weird thing where 100s of thousands of people are visiting all the towns n cities where they expect to see the ecplise in totality. In my country we've seen quite a few solar eclipses but I never heard of people, specially so MANY people TRAVELLING to see it and a massive increasive in tourism for the areas where you can see it from. Some US towns are preparing n announcing as if it's the apocalypse and they are going to be overrun by hungry hordes.
imagine how many rudimentary civilizations that have been snuffed out because their stars path crossed with another, two systems colliding. Imagine being an aquatic creature whose world is brightened two fold as two stars began orbiting each other until they collide, That's a crazy thought, and that's if they even use light as their primary way of navigating the universe. Eyes could just be a earth thing, as life is chaotic it'll be hard for the same thing that led to eyes occurring multiple times on earth to happen on another planet, and that's just life as we know it, "life" could be created in so many ways, we might not even recognize the life shown in front of us because of how different is is
Are you shrooming right now?
Some could help me to understand??? If the universe is 15bi yo and the our sun is now ~5bi yo with more 7bi yo ahead, that means that since the birth of the universe up to now there was only one iteration from start formation and destruction. And if so, how the metals was formed?
Not an expert but I believe the Sun is already a second generation and it is the death of first gen that forms metals etc
Massive stars were much more common back in the day. Many more supernovas were happening to metallify second-gen stars like Sol.
The sun is part of potentially the 3rd generation of stars. The first generation, dubbed "Population III Stars," would have been absolutely massive stars. They'd have been enormous, larger than any stars around today, as well as brighter and hotter and made almost entirely of hydrogen, a bit of helium, and a pinch of lithium. Thus, they'd have gone supernova after short, hot lives and created much of the first generation of metals in the universe.
Population II, the stars that came next, have low metallicity, but more than the first generation. They are still around in the centers of galactic cores and in globular clusters.
The sun is a member of Population I, the newest batch of stars. These stars have relatively high metallicities compared to older stars, around 1.5% or so. During the life cycles of larger and hotter stars in Pop II and even Pop I, many have gone supernova or become neutron stars, some of which have collided with other massive bodies, like other neutron stars. All of these events have produced heavier elements over time, as well as producing more stars.
Remember that not every star has the same mass, size, or composition. Even in the same generation, stars will live and die at different rates. Therefore, metals have been created and spread through the universe since the very first collisions and star deaths in the universe, and haven't stopped since.
should be used on every social media site tbh
I have a thought about the heating thing of the corona: Friction and sound. The sun is LOUD, it would be as loud as a jet engine if there was air between here and there. But there is no air, and in fact the sun's glowing parts are plasma, then there's a liquid part on top and a gas part above that (it's what physics requires).. I'm thinking that plasma and liquid conduct sound quite easily, but as soon as the air gets thinner, the energy gets turned into heat when the atoms that are zipping around get bumped into each other at something that's more of a blast wave than sound.
The sun has been there every day of your life - Laughs in Northern Norway :D
Just in time for the eclipse tmrw!
WAIT - THERE'S AN ECLIPSE ON THE 8TH??? There's been so little about it on any sort of media...
Great compilation, although having to ONCE AGAIN tell people to not stare at the sun...well, maybe those people should.
Thanks for sharing, Read!
Wow❤
I know the sun very well. I see them every day.
R, we love your charisma, your enormous amount of knowledge coupled with your BD energy!
It be awesome of you could do a video on the earthquakes on the east coast
Reid is the kind of science communicator that capture the mind of youth these days.
Here comes the dun dodododo here comes the sun and I say it's all right....
The Galactic Current Sheet don't need no badges. Note: The fact light alone can evaporate water without any heat applied IS NOT IN THE CLIMATE MODELS to account for solar daily and seasonal inputs. The studies (drill cores & like real science) track and prove climate follows solar activity, not bipeds burning things.
couch?!
that is crazy how helium was discovered
Ah, so that's why the sun turns green when I state at it for too long
Something something astrophage.
Reid: Thanks Reid.
if the sun is surrounded by a hot blanket of the corona, why is the interior cooler? wouldn't it eventually heat up to match the surrounding layer? could whatever is happening be used by buildings to be cooler than the surrounding walls or air?
it's strange to think...it gets bigger because it's hotter, but it's redder which is cooler...? so if i wanted to touch the sun do i go by it's radius or color to determine who painful it would be?
if all objects tend to attract each other, why would a cluster of new stars tend to fly apart from each other? it seems like while the odd one might fly out shouldn't the general trend be for things to hang around each other (or worse 🙂)
They redefined the meter slightly to make the speed of light EXACTLY 300 thousand kilometers per second. :-)
Dude I had my phone in my pocket and I legit thought I was listening to Neil deGrasse Tyson
Shut up about the sun! Shut. Up. About. The. Sun!!
~Gabe
The sun orbits the Milky Way every 225 million years, and half that orbit is not visible being blocked by closer suns. So you will not find where the sun was born with any accuracy.
Reid really cracked me up this video 😂😂 so good
The sun is a mass of incandescent gas; a gigantic nuclear furnace.
assuming Earth is a perfectly spherical cow =)
Also the Parker Solar Probe is to be launched in summer 2018? So its already been launched?
Just one piece of feedback on this one - it really would have been nice if we got to see more of Reid! 😂
About 32:50
Why do scientists even worry about whether Earth still exists when it already will have become a lifeless hellscape like today's Venus?
The universe also may not have as long of a lifespan as we think
I don't understand how the center and surface of the earth can differ in age. Wasn''t most matter created at the same time? Is matter re-aged as it recycles through stars or takes on a different composition? Or does it mean the time that matter got added to the earth like an accumulation of "space dust"?
About 32:00
Let's move Eath further away from Sun gradually.
What if we're actually near the end of the universe and just don't realise it, may be the reason for the significant acceleration of the universe, maybe it's just slowly pulling itself apart
It's good to ponder wether discovering water molecules on a planet isn't just a false positive because it's just matter ejected from it's star.
The centers of the Earth and the center of the sun, being younger than their exteriors could more simply explained by comparing it to how a microwave cooks from the outside in 😄
Except those two things aren't really similar in any way other than there being a difference from surface to center. Time passing and spacetime curving are not radiation, and they're not working from the outside in or being thrown at the Earth. So I don't think it's actually a very good way to illustrate the idea
The Solar System was moved here from another Galaxy.
What happened the Parker Solar Probe? What new things have we learned since it's gone around the sun a few times or is there not enough data yet?
Finally. I have craved knowledge from another bald man for years.
How do those who Sungaze daily adapt to the light?
Reid! Reid! Reid! And Reid 🎉
If the earth is accumulating multiples of tonnes of space dust on its surface per year would that not need to be taken into account as well? I.e., how many tonnes of new mass is accumulating on its surface per year times approximately 4 billion years with a weighted average of the new material to take account of how long it’s been traveling with the earth.
When I close my eyes in the sunlight i see green
Barnards Star was a main sequence star too and look what happened to it proving it was NOT a main sequence star (just like Earths' Sun is a recurrent nova). Its show time folks. When will we be let in on the playbill? Next 40 years and the theater is going to be emptied.
Not only astronomers love ballparking....
Lisp!!!
Hang on a moment, towards the end its mentioned that the suns mass would half so doesn't that mean the earth's orbit will change or even deorbit, I'm not s physicist or anything so I'm just going to leave it out there.
SOOO.... In science fiction, I see that if a couple of different things travel at different times, they do not exist in the same time line. If the sun's core is 39,000 years younger than the surface, it doesn't at all mean that they are on different timelines, but how does one think about it? I mean, for exmaple, rock A and rock B are next to each other. rock B is 50,000 years older. How does that affect the other rock and vice versa? How does relative time affect matter?
Uhhh idk, we've spoken a few times in the break room, seems pretty chill though
Alpha Centauri is 5-7 billion yo. I thought it was possible we came from the same cloud.
Sick shirt
@3:30 Dating stars IS hard if you're not famous. 😊
At the level of the sun, couldn't it's gravity explain it's containment of energy?
I guess the increasing luminosity from the sun comfirms it. As it ejects matter, it's gravitational pull decreases allowing more energy to be ejected.
"Recent solar eclipse" ... /me looks at watch.
☀️☀️☀️
-Take it away Ried!
-Here’s… ugh… Stephen 😒
How did historic people who worshipped the sun observe the eclipse? Wouldn't the entire civilization get eye damage?
Yeah take it away Reed!
100 th like!😊❤
Being Reid Malkovich
If you lads struggle at dating stars you might ask Pete Davidson for advice, he's a master at it
"Here's... ugh Stefan 🙄"
Reid 🏅 Reid
it is big and hot
🥵
