Simply amazing. Makes you wonder. I'd like to do those 17.5 hours on Emirates first class looking at the marvels, while cruising at light speed . (Indulge me, Let me imagine there is no breakdown of physics)
Travelling at 35,000 miles an hour Voyager 2 will take 40,000 years to reach 2 light years distance from Earth, this is only half way to Proxima Centauri the nearest star to us.
The U.S. is in the process of fessing up that they have been interacting with this planet for decades most likely much longer. Congressional hearings due to be underway.
@@gailcrowe727 saw a saucer as it flew over my house in the U.K. one evening in the 70’s. Been down the rabbit hole ever since. Astronomers recently sighted a galaxy 13.5 Billion light years from earth. Who ever was at the wheel of what we saw might know the secrets of all this. Mind blowing indeed.🤔
@@MultiBikerboy1 In the 1960s my husband and I were woken one night by a very bright light that shone through the curtains and light up the whole room. We look out and it was very bright all over the fields at the back of our house. We went outside into the garden and it was lit up everywhere as far as we could see. We couldn’t see anything in the sky at all. All of a sudden the light disappeared, We never found out what it was, but it was very weird. s
The size of the universe known to us is unbelievably large beyond my comprehension, but what amaze me more is that all scientist and astonomers are in fact constantly looking at history of the universe …… just like in this video, a giant galaxy billions of light years from us, ….. we don’t know what happened to that galaxy today, therefore we will never know the current state of our universe, what the astronomers saw was conditions at billion years ago. So every discussion on astophysics, even though based on calculation and data from so many telescope are all theoritical and history
@@BarbaraMerryGeng He means that we are constantly seeing 'old data' - light that took millions of years to get to us; thus we cannot know the present conditions anywhere outside of our immediate solar system/galaxy.
Understanding the universe is like trying to understand God. It's astonishing what findings we find with the tech we have and yet still millions of unanswered questions.
You cannot say the universe is big or large - it's immense - it's for ever and ever. In other words, the universe cannot be measured in any shape or form. There are trillions and zillions of planets and stars, not even the science will ever know how many. Often, one hears that this planet is the only one where there is life. Only the Flat Earth Society would believe that.
Imagine the type of intelligent civilizations that could be living in that galaxy… I remember watching an interview with Michio Kaku and he believes for every galaxy out there in the universe taking the Drake equation into effect of the possibility of life there’s at least somewhere between 100-1,000 civilizations per galaxy and only 10 who have possibly reached type 3 civilization per galaxy. Our Milky Way is around 100,000 light years across so for any type of communication any civilization might have send out it could very well still be in its way or already here but we don’t have the tech yet to decode it. Only background noise from space that we pick up from other FRBs the WOW signal to this day is the most intriguing in my opinion.
look, i liked the video, it was well put together, BUT, the lobes arent part of any galaxy, theyre more or less emissions that extend a distance from the galaxy, and this is where i have the problem. the miky way has its diameter calculated from one edge of the disc to the opposite edge. the radio galaxy is still a galaxy of average size in comparison to other galaxies. for example, comparing apples and oranges gives such false info and confuses the non acedemic who takes to heart what science tells them, which is factual but misleading. if i bought 2 new cars, both identical, tied a 50 foot rope to the tailgate of one car.......this does not make one car 50 feet longer than the other car. both cars are identical except one has a rope attatched. this is the best analogy i can give as to how this video misleads by using words such as "largest galaxy known to date"........when actually should be said to be " largest lobes found near a galaxy.
@ Michael yes i thought that to as soon as i saw the plumes & you are right, these shows...no matter how eye candy they might be misslead some ppl not aware :)
The general public is mislead in this way on a daily basis. Such as global worming. The media and politicians say "scientist" agree. No scientist do not agree. only some do. Those are the only ones who's face you will see in the media or along side politicians. If they fail to agree there funding will be cut. There so many ways the general public is deceived daily science and then respectable scientist wonder why the public has a distrust of science. I'm with you Michael, Be truthful and honest. The truth is just as exciting as fiction when it comes to science.
@@leostgeorge2080 yes leo, i believe you are correct with the global warming, governments espessicall here in australia, are doing "behind the scenes" work to prove global warming.....this is how they have convinced most australians in the past ten years. Australia is hot and dry and has always been prone to bush fires and floods, this is a fact that dates back to before white settlers. To combat this, back burning was a yearly event in australia but 14 years ago, this was STOPPED, and the people and the aboriginal people all warned that not burning in winter would lead to huge disasterous fires in summer, and believe it or not, weve had deadly fires that are uncontrollable almost every year. and the climate people never mention that back burning has stopped. they just say the fires are a direct result of climate change......this is also the case in the nsw and qld floods, at certain points during the year, the dams were only kept at 70 to 80% to allow for extra rain in our our ten year rain cycle, but alas, a single year before the worst floods in history here, the dams werent released slowly to vent water over time, they simply let them overflow to deliberately cause floods. and guess what the climate change people said, "its temperature rising in the ocean that caused the floods, when in fact the average anual rainfall has dropped to amounts noted in the 1950s. hence in the fifties the plan was to leak dams 6 months before the rain season to prevent these floods. and it was managed that way since the late 50's,,,untill a few years ago...and were flooding again. guess how many idiots are running around here screaming "armageddon weather events" when nothing in the weather has changed for hundreds of years her, just how its managed. this is and always has been a land of droughts and flooding rains, fires and storms.
Yea I know. Some guy in the news is self identifying as a head of cabbage and is trying to go agriculture exempt on his taxes. Dudes with boobs and chicks with dicks. No wonder why aliens run like a mofo when we see one. Oh except the atmosphere red bull jumper . You know they all tilted their heads and looked at each other on that shit .
I hate this over epic high school standard of dramatic narration. It sounds exactly as it is. A person who has no real knowledge of the content he’s on about just hired for the job and reading it with over accentuated pronunciation.
@@frankysplace7105 that's not true, there's still a lot to discover in our own galaxy, dang we don't know well some regions of Earth yet, little the bottom of the oceans, beneath Antartida, the Amazon biosphere etc
“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.” - Douglas Adams, The Hitchhiker's Guide to the Galaxy
Ikr! We typically measure a galaxy from outer star band to outer star band in the visible light bandwidth. However, most galaxies have emissions of some sort (gamma, x-ray, radio, etc). In those regards, practically every galaxy is way bigger than our standard measurement of it. It's akin to the true reach of a star and where interstellar space truly begins. The definition of that edge is somewhat fuzzy, and the same goes for the true edge and shape of galaxies and where true intergalactic space begins. So, if they're going off the radio emissions of that galaxy for it's measurement, then we need to remeasure every galaxy in those wavelengths. Even at the distance of Andromeda and the Milky Way, some say they are already touching.
You must have heard of cyclotron radiation in your high school physics classes. If you missed that day, too bad for you, itll take you back a notch or two, maybe Sesame Street... Ah Ah Ah! Two! Two freaking notches! (Thunder crashes)...
This is a good video! Despite the year we're in, I believe that a lot must be learn about galaxy, especially in the realm of radio astronomy. Thanks for exposing this topic to us general public here! 😄
If that galaxy is 3 billion light years away, that means it'll take 3 billion years for light to travel from this planet to that galaxy. Or if you want to send a message - same time. An answer, if there is anyone who picks up your message, you'll get that in 6 billion years from when you send it.
@@craigthescott5074 exactly - our existence proves it possible, and it's mathematically highly unlikely, given the trillions of planets, that we're the only one. It's arrogance or clouded thinking to believe otherwise.
It isn't whether or not there's other life, it's almost infinitely unlikely that there isn't/wasn't/won't be - but that the problem. The real question is if any of it has reached human or greater level of intelligence/technology. This is a much smaller chance. To make matter worse, assuming most societies such as ours will eventually fall victim to some sort of calamity before successfully living independently off our planet (let alone out of our star system), then our window is only very, very short. What are the chances that over billions of years another life form would reach a similar stage as ours at what is essentially the exact same moment in time? To make matters worse, what are the chances that this insanely small chance of similar life at a similar time is within a reasonable distance - even within our own galaxy? Until we figure out faster than light travel (if it's even possible), then concerning ourselves with Alien lifeforms is pretty pointless imho. If they find us, then whatever happens will be far outside of our ability alter regardless of what Hollywood teaches us!
One thing that gets me; If we are seeing it as it was 3 billion years ago, it could be plumb gone, by now. So could a lot of items that are even down to thousands of light years away. We see nothing, past the end of the solar system, as it really is in the present time. Even the sun's appearance is 8 to 9 minutes old, as we have been told.
Galaxies don't usually disappear. The universe is about 14 billion years old. Yes what we're seeing is 3 billion years ago. The galaxy woukd bot be in th4 same location and certain had changed their star patter as they have all moved.
@@ms.annthrope415 You are correct. I was using that as an extreme example. According to what some theorize, if it were several billion more light years away, it could possibly be past our horizon of the visible universe, now, but then, we probably wouldn't have ever seen it, or even be aware of it, anyway.
Unlikely to have disappeared, our sun is 4.3B years old, that galaxy is estimated at 100 Milky Way galaxy wide, it will remain lots of billions of year still plus inside the visible universe range for a few billion more
Galaxy take A LOT longer than that to dissapear. Rocks from 3 billion years ago are still on earth yet you think that's enough time to extinguish a galaxy? Nothing in the universe can destroy a galaxy, they only "disappear" when they travel beyond the edge of observability. All galaxies that were ever born are still here.
0.24 3billion, would mean a tromendous things have changed, since those aging light, attempted to morph into united comlexity sttucture, from simple energy particle, since it had traveled its optic vision, to hit your eyes, downloaded in your minds.
If you were able to travel to that galaxy at the speed of light it would take you 0.0 seconds. 3 billion light years in zero seconds. Thats special relativity.
Three billion light 💡 years from earth 🌍 with so much energy and this galaxy is mind blowing and quite serious 🧐 for observations of this electrons causing a serious galactic revolution.???
Sherlock Holmes and Watson went camping and they laid there at night looking at th4 sky and thr stars. Sherlock: looking at th3 stars. What comes to mind Watson? Watson: the smallness of humanity.

Just think... there IS a real Xenomorph Alien out there... somewhere... like from the movies. Probably about 10 different variations if you just go by the mathematical odds of it
Considering the odds of life just starting and all conditions being perfect, I doubt that. But I'm sure there's some type of life out there. I just highly doubt 10 different variants of a made up alien race from a movie. And definitely not billions of other lifeforms. No way
@@el34glo59 Let me put it to ya like this... Chances are high... that people on earth (like HR Gieger) dreamed or had visions of the creature in which he turned into art and sculpture. He WAS very passionate about what something looked like to the point it chilled him to the bone. So with that said... it could be very likely something like Alien could exist after all... and closer than we'd want. But here's the thing... If... IF .. one exists. I doubt its behavior would be the same. That could be good or bad. The aliens that Gieger drew... looked highly intelligent and less animalistic... meaning they drive their own space craft and go where they want. Our films seem to have dumbed them down to mere ant-bee like behavior or other savage wild animal status. btw... Im misspelling like crazy here... lol
@@el34glo59 well considering there are 200 billion stars in our galaxy alone and now astronomers are saying every star has planets and there’s TWO TRILLION other galaxy’s out there I would say yes there’s a very good chance there are billions of other life forms in the universe. Just mathematically it’s a certainty.
When I was young, I was always interested in science, the big "argument" way back then, was, the question of whether, the universe would continue to expand forever because it had enough momentum to escape gravity, or eventually reverse and gravity would bring everything back to the big "crunch". what a surprise to science when something not suspected was discovered, that not only will the universe continue to expand, but that it is actually speeding up.
That's exactly what I don't like about so many content creators out there. They don't focus on quality content for their audience but on content for the algorithm. And you end up with what we have right now on RU-vid, clickbaits and light years of senseless b*llsh*t instead of information or message that matters. Pleasing AI is not an excuse for low quality fillers.
What's really mind blowing is the total complete cluster of all the galaxies that is known, is just a tiny microscopic (or nanoscopic etc.) system of galaxies in the infinite space of the infinite universe; but there could be other microscopic clusters of galaxies... who knows what's out there... And this terminology microscopic/nanoscopic galaxies is useless, actually, in relation to them being in an infinite universe.
Too bad people don't understand that EVERYTHING in these videos is animation and illustrations. Too bad they don't know that the actual pictures and images are never promoted.
The farthest known planet from the sun is Sedna. Sedna takes more than 11,400 years to orbit around the sun. Sedna is a dwarf planet beyond Pluto. Sedna is smaller than Pluto. Not much is known about Sedna. Sedna was discovered in 2003. Pluto was discovered in 1930.
I wish I'd gone to whatever high school you did that discussed the cyclotron... best we had was those little steel spring catapults that the kids would put trash in to try and pelt one another with.
All ancient civilizations already spoke about the size of the cosmos more than 15000 years ago we are just rediscovering the wheel and patting our backs when we can spend the same money on helping people on this planet
Back in ancient time the greeks and romans also thought that the world ends at the pillars of hercules untill some brave portuguese explorers proofed them wrong and discoverd worlds where no one has gone before. Perhaps one day someone will repeat their heroic deeds and discover a space route to foreign galaxies. It took 500 years to discover the sea route to india by none other than Vasco da Gama.
Is it considered that Elliptical galaxies are at the final stage of a merger between 2 or more galaxies? If it is then law mass of its central blackhole can be explained as not yet merged with the other central blackholes.

6:08. Tell me exactly WHY you would compare the mass of a “large” galaxy to the mass of the Sun?? Think about it for a second. Even ONE second of thought should have produced a comparison of our galaxy, the “Milky Way”.
He said at 5:45 that it’s as wide as 100 Milky Ways being lined up end-to-end. He only mentioned the Sun when giving a size reference for the black hole located in the center of the galaxy.
Cyclotron radiation is a part of school curriculum? This is the first time I've ever heard of it. Is that something to do with the way you see light in a 'tokamak' fusion reactors?
