Scientists Have Detected the First Stars
• Scientists Have Detect...
See that fuzzy blob on the sky? The one just left of the Milky Way center in the constellation of Andromeda. That’s M31 - the Andromeda galaxy. It’s two and a half million light years away and host to a trillion stars. It has a beautiful spiral structure spanning its gently rotating disk 220 thousand light years in diameter, and a central bulge that hides a giant black hole that contains the mass of well over a hundred million Suns. Andromeda is also racing towards our galaxy at 110 km/s.

When you die it'll feel like 1 min 😭😂 Kinda good its 4 billion years from now wouldn't want to be here when it collides actually noone will unless we woke up and stop thinking bomfires like cavemen is the greatest source of energy in the world lmao lets get to the next step in civilization ...

@@earthspeakers How would we die during the collision happening?
Fun theory: The black hole centers of Andromeda and the Milky Way could be connected by a wormhole!!
It's crazy because in Andromeda, they may be talking about crashing into us. That's insane to think about
I bet they gave our galaxy some scientific nerd name... meanwhile they named their own galaxy something that sounds delicious like we did.

After watching this video, there are moments like this when I wish I was not an atheist. Wouldn't it be wonderful to exist forever; to learn the fate of not only Andromeda and the Milky Way, but of all existence. I can still remember my freshman astronomy professor telling our class (I'm paraphrasing): "Many claim astronomy is a sad science. The universe is so large, the distances so great; we will never understand the nature of it all. This class will be a detailed refutation of that claim." Although that professor is long since dead, I hope he would be pleased to know that, some 55 years later, his words were so astute and still fresh in my mind. Although I'm about as far from a scientist as it is possible to be, I am amazed at the mind-boggling discoveries I've witnessed over the decades. Shakespeare summed it up nicely: “To die, to sleep - to sleep, perchance to dream - ay, there's the rub, for in this sleep of death what dreams may come…” (Hamlet)
Everything is so big that is beneath human comprehension. Just thinking about the fact that someone in a relatively near planet in our galaxy has is own story, myths, maybe religion, his own scientific discoveries, their own understanding of life and space, their own names and definitions for it all, maybe discovered our planet and overlooked it, maybe they are trying to communicate with us because they are at same scientific level or they are way superior and we look as evolved as apes to them. Maybe we are superior and we'll never know. Multiplicate it for the billions of planets in the universe... Scary and fascinating.
What fascinates me the most is the fact that being the chemical elements a finite numbers in a infinite universe is that somewhere out in space, there has to be "another us".
@@fabiofioretto9374Your a kindred spirit Fabio so big and so small is our universe. There's no center to an infinite universe. I wonder where on the spectrum of small to large do we belong? Oh well 6 billion years to the universe is just a stutter step. For the endgame you should read the short sci fi story "The Last Question" by Issac Asimov.
what if, as an atheist, you put some elbow grease into the science of medicine instead?
@@TheNeverposts Like astronomers, the scientists at the Centers for Disease Control have an understanding of medical science far beyond my own. My regard for the disciplines of all scientific effort is tied to the ethos of evidenced-based reasoning.

Just cancelled my gym membership due to the anticipated collision. No way I get good enough to outrun the 17km/s transverse velocity to dodge it. If, more likely, I didn't fall off the edge of the world.

RUclips actually recommended your channel to me when I was binge watching Space Time a few months ago =3
Remember, it's okay to be a little crazy 😜
Channels come, channels go, and PBS Space Time is still my favorite on all youtube.
Lucas Balaminut I agree, PBS Space Time is the only channel I have never unsubscribed to.
It's not even the best space channel on youtube (Vintage Space)
First of all, PBS Space Time is not a "space" channel, but a physics one. Second, I never claimed it was the best, I said it was my favorite. Third, even if I had claimed it was the best, without an objective standard, "best" is a subjective evaluation and will naturally vary by person.

"The two galaxies will inevitably collide" Challenge accepted
- Isaac Arthur :P
Yes, given the amount of time, we can organize starlifting for all the stars in both galaxies and coordinate a dance of stars into some fancy new method of orbits.
Knowing Isaac, he would probably be glad for all the extra matter. We don't even have to go there to harvest it, it's coming straight at us. Think of all the rotating habitats we could build with all that stuff.
A decade from now we notice the galaxy slowing. Not slowly either, several percent a year. Five years later its stars start to dim and go out, their mass hidden or converted somehow. This is of great interest to everyone and confirmation of intelligent life elsewhere in the universe.
Then it starts happening in our own galaxy.
+Gareth Dean Lmao what was that about, mate?
A possible future. Perhaps, across the massive void of space, a civilization ahead of our own is already planning. To convert the bulk of both galaxies into inert fuel so that they may live a billion billion billion years instead of dying when the stars go out naturally. Perhaps they see us as little more than bugs to be exterminated. Perhaps they wouldn't even notice our dying screams at all.
good that we know this in advance and can make preparations by then , we hope
We gotta get out of this place!
If it’s the last thing we ever do?
Why?
What I find fascinating is not the fact that we care about what will happen to Earth in 4 billion years, but the fact we seemingly do not care about what will happen to Earth in next 40 years.
That's largely because we care so much about what happens to US in the next 4 minutes. I'd recycle, but the bin is way over there. I'd eat healthy but pizza tastes good. I'd help the poor but I wanna watch this movie...
You saying its the little things that matter :)
The _Earth_ will be fine. _Humanity?_ That's a whole different question.
Humble Evidence Accepter sounds like a belief based off of religion, bye bye.
@@sorryidgaf.6043 My point is that the Earth and life existed Millions of years before Humanity; It will exist after we're long gone as well. This planet and life on it have survived calamities worse than what humans have caused. We could render Earth unfit for humans, but not life itself.
I really love this show.
You manage to make complicated physics easy to digest, and at the same time, you keep the integrity.
Especially the last thing i tricky... Some are way to liberal and/or excited about new theories, while others are so afraid to be labeled as such, that they are TOO stringent on what can be talked about...
You strike a great balance, and your interaction with the viewers are a great touch as well.
Thank you for a great program, and please keep it up!
It will be the single most amazing sight ever, and the scariest, idk whether to be happy about not seeing it or sad
"I see the sea and wonder
If on some distant shore
Someone is standing, staring

That's weird. I just thought about the Andromeda Galaxy yesterday and how far away it is, and calculated how much closer the galaxy actually is by taking into account the light-time delay. -Turns out the Galaxy is approx. 156,818 light-years closer to us, or 6% closer than the light we see today.- Pretty cool seeing a video about this the day after I thought about it :o
DyNamic I'm pretty sure your numbers are off. Closing the distance between Andromeda and Milky Way by 6% in just 2.5 million years would have Andromeda crashing into us in just under 42 million years.
Andromeda is a little more than 2.5 million light-years away and moving toward us at 110 km/s. In 2.5 million years Andromeda will have moved 2,500,000 * (110/300,000) light-years or 916.66 light-years. I didn't factor in acceleration due to gravity so that might add a few more light-years but certainly less then 1,000 light-years.
Thanks for the reply. I did this calculation the other night and I completely forgot how I did it. Dammit. Anyway, I think you are right in correcting me. I was having one of those spontaneous brainstorm moments and was bound to mess up something in there.
Lol at least you’re using your brain to problem solve and think abstractly unlike most other people on the internet
110 km/s x 2.5e6 yr x 3.17e7 s/yr = 8.7e15 km
8.7e15 km x 1.1e-13 ly/km = 960 ly
960 ly / 2.5e6 ly = 3.8e-4 = 3.8e-2 %
so .038% closer than it appears?

Same. The artist renditions were great. That's what I came here for.
Oh heavens! Another merger - and the possibility of being transferred to another organisation without knowing our final entitlement :) Excellent video!
So many souls died in this computer simulation collision all in the name of science. #stopsimulatedlifemassacre
right lol
Imagine if our universe is just a simulation done by someone in order to figure out their own universe XD
we just a considens in the code, they properly testing for something completely unrelated to the milky way
They, uh, don't simulate that level of detail, but you knew that, and it was a joke, and I probably should just delete this comment
+drdca Well it's a legit idea though. A very advanced race could be running a simulation to analyze who knows what problem, and we could just be an emergent phenomenon within it. Google "simulation hypothesis." I don't put much stock in it but plenty of people who are smarter than me think it's worth considering.
Eric J Oh, sure, but that didn't happen with the simulation mentioned in the video

Hey, just letting you know that there was a recent study done on the andromeda galaxy that revised the estimated amount of stars to around 800 billion and revised it's mass to roughly the same as the milky way galaxy.
John Kicklighter yes , i had read .
Wouldn't that put it at twice the number of stars compared to the Milky Way? Implying that most of Andromeda's stars are lighter than the Milky Ways? Not sure how that'd work.
+Himanshu Goel
Some astronomers have recently come to the conclusion that our galaxy is nearly the same size as Andromeda and perhaps even bigger than it.
Ah... Dark matter partially explained by massive Andromeda and Milky Way recalculation. I know Andromeda got much smaller, and M.W. got many more stars without changing in mass much, but the fact is that we had NO CLUE about the luminous and baryonic content of our own galaxy and nearest neighbor, and probably still don't. Antimatter was newly found right around Earth and also is hiding in protons. Glad that's over too. It's all just spin.
Size of Andromeda is still 2.2 times larger than Milky way. Also stars are 1 trillion. But Milky way has slightly more dark matter which means Andromeda which we thought three times massier than Milky way is now reduced to 1.76 times. Afterall Andromeda is still biggest of our local group. And who knows Andromeda's actual size. It may be even larger

There was an old DOS program in the 1990s that did galaxy collision simulations. It was quite fun.
Wow DOS!?!?!? You don't look that old.
The M-31 is 2.5 light years away. So whatever was observed by the Hubble telescope was released 2.5 M years back by the M-31.
Since our nearest stellar neighbor is over 2 light years away, and takes 2.5 YEARS not millions of years, to reach us. I think you need to check that figure. It isn't surprising to find that people don't grasp the ENORMITY of the distances and sizes of things in the universe. Even the top physicists have anything close to a true grasp, but even for them, it's too much to FULLY encompass on a human scale. It's fascinating to realize that every molecule on earth, and even in our own bodies, was once part of a star that blew up millions of years ago. We are entirely made of "star-stuff." That's awesome.
This is not easy to do in one seamless take. You did a good job.
I'll give this video a like just due to the "Science Asylum" T-shirt alone.
Props to the Science Asylum shirt, you should have him on a guest and be a guest over there
Milky Way: bro watch where your going I’m spinning Here
A parallax measurement of range would be more convincing. Let's work on that. Then trajectory could follow.
I hope that humans evolve into a complete different organism by then so that poor Andromedians don't have to put up with our shit.
I think that's racists ;-) Andromedians ain't perfect. They are working through their own problems just like the rest of us.
And hopefully we'll all have worked out our shit before we come in contact we each other. Good luck though, lol.
Maybe the Andromedians are saying the same thing about their shit....................
We will be long dead by then, well obvious that goes for us right now but i mean for the human race. Our own Sun is dying faster then they expected, without Sun there's no life or food.
CRTukker You realize that all these predictions are theories based on data gathered within a very very short period of time, right? The laws of physics may not change, but our understanding of them will, resulting in wrong/incomplete predictions of our universe. We don't even know what dark energy and dark matter is, neither do we know what occurs inside a black hole, or that why GR is not compatible with Quantum physics. Hence, it only shows our arrogance when we pump out theories after theories on how the universe will behave in billions of years.
Galaxies don't go away from each other, the space between us is becoming bigger
Knowing both how big the Andromeda galaxy really is and yet how small it looks in the sky truly makes me realize just how unimaginatively far away it must be! So anyone besides me that knows what I'm talkin about can comprehend that it just boggles the mind.!!
I just got served a 36 minute ad. LOL
I was hoping for a cereal- milk demonstration.
I guess I should have eaten before jumping on YT.
By 4 billion years humans will be a distant ancestor of the lifeforms that inhabit Earth and other planets we may have colonized. What species is expected to stagnate for 4 billion years? Also, we will probably have figured out how to extend our star's life span by harvesting materials from it well before 4 billion years.
Before that, let us hope there won't be a third world war😂
Having been to the South, I can attest that humans can stagnate for at least a few centuries unfazed.
I seriously doubt humans will ever colonize anything past Mars.
Perhaps you underestimate how we are like an infestation. We spread to new areas and proliferate rapidly. We drain resources without considering consequences. If there is profit to be had in any endeavor we will exploit it mercilessly. It may take a while to figure out how to do it. Look on the bright side, we might wipe ourselves out before we can spread.
Aric Majere yeah that's what I meant. Humans have a horrible ability of screwing things up.
Milkdromeda sounds like a name for a new Jamba juice smoothie
Matt makes anything sound like it’s not scary
The fact that the nearest galaxy is racing straight for us is a pretty good joke.
Gordon Chin joke ?
Its not the nearest galaxy. Joke?
GDI yes it is, what’s closer? And yeah it’s morbid but it’s still funny kinda like a character seeing an ironic death coming right at them
I don’t understand the joke
One of the Magellanic clouds is closer to the milky way. I'm not sure if it's the large or small one.

Andromeda is pulling us toward it. It has a lot more mass and it's garvity is tugging at us. So it's not racing towards us. We are going towards it.

When you say it could shortly form a quasar, would that grill everything in the galaxy ? Wasnt that like super dangerous ?
The dipole jets of a quasar blast perpendicular to the galactic plane. That galactic plane is where most star systems orbit so the answer is no. It would only grill the stars that lie outside of that plane such as those inhabiting the central bulge or satellite galaxies.
An intra-galactic quasar may be perpendicular to the galactic plane, but Andromeda isn't arriving horizontally, so there is a possibility that the jets from the inter-galactic quasar could sweep across the new Home-Galaxy, sterilising all multi-cellular life.
Wouldn't the galactic plane be the plane of the combination of the two galaxies after combining and so one big happy when the quasar ignites?
I love the questions about cosmology and astrophysics!:)
Reckless Roges It won’t sterilize all life due to the fact that stars are so far apart that at least 1 trillion planets at minimum will be spared.
FUN FACT: 4 billion years later they will pass each other without crashing and the generation then will be laughing at our supercomputers
Andromeda's approach is like Sir Lancelot approaching Swamp Castle.
Imagine an alien in andromeda whose perception of time was really slow just seeing the milky way swoop in super fast. It'd be terrifying
Wow! That sounds terrifying and amazing to watch!
If I was alive during the collision I would just be sat outside watching
Dark_ Void and if you think about it, you’d probably looking at the collision from Europa, titan or mars because of the sun in the process of being a red giant.

4-6 bilions years ay. What a time to be alive...
So, short version: gravity is very weak, but it's very sneaky and persistent.
its basically the 500pound Gorilla, in Sneakers!
I wish I could take a glass of a heavy dose of being extremely clever :(
Incredible as always 😍
You would wake up one day on a different planet and look up at the sky and see many new planets.
Good thing I have notifications on for PBS Space Time, because it did not appear in my subscriptions
BaseDelta0 You should try subscribing.. Kappa
If you could sacrifice the rest of your current life, your lifestyle, the people you know and care about, etc, and in exchange become an otherworldly spectator to watch the events of the universe unfold, time-lapsing at whatever speed you desire, would you?
The reference is Kokkoku, btw.
I'd miss bacon. And chocolate. I'm assuming I'd be detached from physical pleasures.
· 0xFFF1 yes, the universe is infinite and it would be awesome to drift in the cosmos for eternity

I would give up everything just to explore the endless space.
Weird to think that there'll be no humans around to see this happen. We'll be long gone, a barely noticed moment in time that would barely register on a graph. Crazy.
This is an excellent presentation. Answered all of my questions about when our sun would become a red giant vs milky way collision with Andromeda. Thanks.
Won't the sun burnout and most likely destroy Earth before this happens anyway?
That’s what he just said
If we move to a new solar system or figure out how to make stars, we'll likely still be here in this same galaxy if still alive in some form, lol. So yea, beings could still be around to be affected at that point potentially, you just have to hope humanity somehow makes it out of this solar system alive and with the capability for sustained life elsewhere ;)

Not if it learns to rest instead of just exhausting all its energy. I mean, what good is that doing :)
Your time is 8:20
Sun burn out in 8 billion yrs I thought
@@poopiettv5270 the life will end in 4 billion years as sun goes red gaint phase
So, watching the two galactic centers (black holes) merge made me wonder: If both black holes were spinning in the same direction relative to each other (let's say clockwise), but the collision happened in a counterclockwise spin, would that change the spin of the black holes? Further, would that change the spin of the newly forming 'Milkdromeda' galaxy? If so, I feel like I need to start preparing for such a change... :)
Or one of the 2 blackholes would just flip. If you think about it, the rotation of the galaxy couldn't change, because at some point objects would need to reach a speed of 0 m/s relative to the core in order to change rotation side, making them fall in a straight line toward the center.
Depends if your in northern or southern hemisphere...
There's a pretty big mass difference between Sgr A* and Andromeda's SMB, 4 million solar masses vs over 100 million solar masses. If the collision were opposite Andromeda's SMB spin it would slow it down, perhaps tilt it somewhat but not enough to reverse it.
on such a large scale, it’s probably a merger instead of a collision
I plan on being around to witness this event.
You will be, but not conscious 😂
