This TH-cam channel is like flypaper for science. Enthusiasm, joy of discovery - it's an ongoing advertisement for STEM studies. And that's a good thing!
It's crazy to think that there are people still alive today who were born into a world that believed the Universe was no larger than the size of our own Milky Way galaxy. It's a great reminder of just how far astrophysics and cosmology have come in just the last 100 years.
I do not have a "bucket list' for I do what I want when I want... but after watching Dr. Becky, I have 2 new ones, after surfing under the Golden Gate bridge (not done for broken board and broken body parts), 1) a visit to Mt. Wilson, I live in L.A. and 2) to see the rings of Saturn through a telescope, I have seen Jupiter's moons several times, Galileo must have surprised himself!
That would be me. Although the scientists already knew better, the astronomy books for little kids hadn't caught up by the time I came along 85 years ago.
@@annmoore6678 Good point. My mom is 93 years old, so hardly anyone would have caught up with the news in 1931, especially given how little access people had to science information. She did have access to a set of children's encyclopedias when she was a child, but they were published in 1891. (I remember poring over them myself as a kid a generation later!)
This is true even for continental drift - and the age of the Earth. There's one line that's stuck to my mind, from the original 1954 Godzilla: they speak about the age of the dinosaurs being 2 million years ago.
And this, combined with the Internet facilitating the spread of false information, has resulted in a general public "golden age" of resurgence of ideas like young Earth, flat Earth, and other obnoxious pseudoscience... which has had a noticeable negative effect on our society's receptiveness toward science in general; just look at some of the responses to the pandemic. And this in turn has negatively affected our society's political perspectives. People who don't see the connection between science and politics are just choosing not to look for it.
When I was a tiny astronomer I can remember looking at the images of galaxies in the 1977 time life encyclopedia titled "our universe". One image in particular had an "interloper" in the corner next to the main galaxy. I remember thinking " there are Interlopers?!?!" I never imagined we would be looking at images with thousands of galaxies. There's SO MANY!!
'List' videos and programmes usually leave me cold, but this is fantastic! The combination of enthusiasm, excitement, descriptions of astrophysical techniques, a smattering of panicky hope (during the JWST launch) and your ever-present love of the subject makes this amazing. Thank you so much. Bring on another list..
@@DrBecky Assuming the Universe is expanding & there's been no new creation of matter since the BB, doesn't that imply that the early universe was denser that it is now? Has that been taken into account for the apparently early formation of galaxies?
Loving the idea of a "record breaker series", you should definitely do it in my opinion. "Game changer planets" spring to mind too. A list of planetary discoveries that changed what was scientifically possible - gas giants being closer to their star than rocky planets, the planet that's a mix of ice and fire etc. also "smallest planet discovered" ?, "most / least planets in a solar system" ? "densest galaxies" ? would love to see more like this along with everything else you do. Thanks for the great content
Love the idea of record breakers for a series - looking forward to more! Maybe the most massive (and least massive) stars, galaxies with the most stars, or the most energetic light detections.
Thanks for making this. I love the idea of record breakers. You're one of the only channels I watch that isn't computer science, and super excited to see more record breaking stuff.
@@DrBecky Oh boy I would definitely enjoy that video. I was actually thinking of making one, but I'm not a physicist so I never did. Looking forward to watching yours.
I like the record breakers series idea, but still my favorite content of yours is the historical reviews of how we came to certain conclusions or discoveries. The way it incorporates history and personalities makes it engaging, while demonstrating the back-and-forth of the scientific method makes it some of the best science education on TH-cam.
Dr .Becky: I found a great explanation of physics: Aristotle said a lot of stuff that was wrong. Galileo and Newton fixed things up. Then Einstein broke everything again. Now we've basically got it all worked out except for small stuff, big stuff, hot stuff, cold stuff, fast stuff, heavy stuff, dark stuff, turbulence and the nature of time. 😛😁😉 Keep working on letting us know the nature of stuff and what it all means. 😊
I do love these "history of" videos. The thing that resonates with me most is what I call the log plot of knowledge. It's easy to see that the time between "big" discoveries decreases, but then you realize that the same pattern will happen if this summary were made in the 70's or a century ago, or a millennium ago. I think the reason it resonates is that it highlights how much progress can occur when we work together. Setting aside the content of papers entirely entirely, just seeing how they go from "Scientist" to "Scientist and collaborators" shows just how much deep, foundational knowledge is needed for each and every discovery. And the technological advances required at every stage to support these discoveries underscores the "we do these things not because they're easy, but because they're hard" because of the dividends they pay toward improving humanity.
I think it would be awesome to have a video coupling Dr Becky’s knowledge and passion for this field of study and epic spaceman’s amazing video effects and sense of theatre he creates in his videos. Would be a dream come true
Dr. Becky’s enthusiasm and passion for the astronomical world is so captivating and inspiring! She makes the best astronomy and astrophysics videos! The majority of people can understand and appreciate the information she gives to the public without being too complex for ordinary people to grasp. Though I’m a giant space nerd and have studied science and math for my degree in Cell and Molecular Biology (which I wish I had studied astrophysics instead, but so be it). So I can understand some of the more complicated aspects of the astronomical fields of study than most, it’s still a very challenging subject. The levels of knowledge about advanced mathematics and physics needed to be a part of this scientific community is impressive! But Dr. Becky has a way of explaining things to us all that doesn’t go over our heads and keeps us engaged and interested all the way through! She’s definitely one of the best science educators on TH-cam!
Great Video and idea for a series, would definitely watch more. Pleas think about ending on a chart of some sorts. Thou I watch many of your videos I don't have an intuitive grasp on units such as redshift and a visualization would help me immensely. Thank you for your great work!
I’d love a video on record breaking black hole sizes vs distance. Is there a limit to what we can detect on black hole sizes vs their distance? Also, are there any sources I can see to better understand red shift? I don’t understand how we can know something is red shifted. Love your videos! You’re the best!
When I go walking before dawn, I marvel at what I can see (when it is clear! 🙂) The reality of the cosmos is (almost) infinitely greater than that, as JWST reveals more and more. All the JWST objects are streaming photons in every direction and we intercept an infinitesimal radial arc of the whole so I was wondering - How many photons from one of these most distant objects might touch MY sq metre of earth a second/hour/day? I love your presentation of the science but it would add to my wonder if I could 'feel I was being touched' by these galaxies near the origin of time itself!
Hi Dr. Becky and all. I really enjoy your astronomy videos. I'd like to see videos about exo-planets and black holes. This video about "most distant galaxy known" was great.
Astronomy records will be an excellent series! The youngest and oldest stars, planets, star clusters, ring systems, galaxy clusters. History of discovery of the elements on earth and then in the universe. Highest energy particles. The possibilities are endless.
Superb as always. Thank you Dr Becky. I have recently had my brain function improved by the Royal Papworth Hospital, who realised that the MND with which I live had progressed so they gave me a Bipap / Nippy machine meaning that for the first time in a year my brain is getting enough oxygen at night. During the worst part of that year I criticised your choice of sponsor. What I wrote [long since deleted] was poorly judged. I am very sorry for my error. The content you produce is always scientifically correct and yet accessible to all, and that is a rare gift, so as a former A-level science teacher that is a thing dear to my heart. I hope that you can forgive me. Thank you, love from Dr Rick, artist in residence at Under the Thinking Tree, and at the Readable Research initiative at the Sheffield Institute for Translational Neuroscience.
Thank you, Becky. That was terrific! One thing I've never read, is how redshift maps to time, and distance in that Z dimension. Z, not meaning little z for redshift, but Z being the upward coordinate of a three dimensional space. For example, if we could stack GN-z11 on top of our champion JADES-GS-z14 in that Z dimension -- just imagine the hand of God reaching in and moving GS-z11 in front of JADES-GS-z14 from our perspective like a piece on his chess board -- what would the difference in distance between be? Have you ever seen the early 1960's film with Ray Harryhausen special effects, Jason and the Argonauts? That was my inspiration for the Chessboard of the Gods.
I'm curious to know if all of the galaxies that we routinely observe, are traveling away from us in a perfectly linear fashion? If these galaxies were to deviate even the slightest, then would it be possible, with all of the modern advances in technologies and telescopes, to actual see the same galaxy, but at different points in time?
Yes, by all means, let's have a record-breaker series! That would enable me to get my brother (83, engineer and retired pilot) on board watching your videos. And as we know, once you start watching Dr. Becky, you are hooked!
Thank you Dr Becky for a whirlwind tour of history. Question please: What if we find a galaxy with redshift of more than 14 billion years? Will that mean we "age" the universe a little older?
Yes please, record holders through the time series would be amazing! Biggest stars known! Hottest stars known! Black holes and exo-planets and pulsars! All of that
Maybe a stupid question, but if the universe is estimated to be 13.8 billion years old, then isn’t it singular to be finding, what I presume, are developed universes at 13.5 billion years?
I would like to watch your live seminars in your University you work at. Your enthusiasm is great and contagious. Our city is getting Brighter and Brighter as the Council expands outwarrds.
I remember seeing the Hubble Deep Field image as a kid and it made me so fascinated in the universe. Could not properly understand the scope of what it was I was looking at but it made me get my own telescope and asked my parents to sign me up to an astronomy club.
You know it's been a long couple years of discoveries when GnZ11 feels like forever ago (and the correspondingly bafflingly big M/L ratio results). We're eating good with the JWST data. Great vid, Becky! Stay hydrated in the heatwave!
Do we know anything about these galaxies, such as: 1) Do they have stars? 2) Are there black holes? 3) What elements are in there? 4) What is their type/shape?
The progress bar was a very nice touch to keep up with all the record breaks. Also nice to see how Keck was such a great partner for Hubble, but it seems like JWST is more ‘self sufficient’, or that the ‘partner scope’ has yet to be identified for a specific usecase?
Wow! So now, it's a competition between galaxies about who is the most distant 🤣🤣🤣. Impressive and really informative video for me, as I am truly in love with Astrophysics and space science. Let's see how many records are broken by the galaxies, as we look back in time towards big bang.
Love the hilarious pronunciation of Boötes (a diesis in a context like this usually indicates you should pronounce both vowels separately). Great video.
I think for car headlights you mostly know how far away they are from how far apart they are, since they usually come in pairs, for cars that is, not for motorbikes, neither for cars with broken headlights. with modern headlights they tend to vary quite a bit in brightness.
Does this not indicate that the universe is older than we’ve previously thought? A fully formed galaxy at such a distance. The universe must be older and bigger than we’ve ever considered.
Nobody has come up with the smoking gun that the universe would be older than 14 billion years, the aggregate data doesn’t support it, those super old galaxies are very tiny and still very primitive
This episode made me think about the cosmic ladder. How far away are we five sigma (or equivalent) sure of distance? What are the error bars like on something like gnz11? What is needed today or next to fix farther distances?
How do we differentiate between inflationary red shift, non-inflationary velocity red shift, and gravitational red shift? Gravitational lensing, supernovae, or more ornate guesswork? Per General Relativity, velocity and gravitation should be (almost) the same. And black holes should gravitationally red shift towards infinity, but on a spinning almost point source.
When calculating total redshift and distance, do you have to account for the rate the object is moving away from us WHEN that light was emitted? As in. Total red shift=Doppler Shift(v(t) t=emitted) + Expansion Shift
Add my vote YES to more record breakers. You haven’t done much on neutrino astronomy, which is understandable because it’s kind of in its infancy. Still, we have piles of data from many sources. What do you think the future of neutrino astronomy will look like? Will we ever get a map of the Cosmic Neutrino Background Radiation? If so, do you expect it to match up at all with the CMBR maps?
Well, we don't have to be BIG or a center in order to be important for ourselves. I'd rather than pitying about how small we are be glad about how big the Universe is.
Great video, thank you Dr Becky. The graphic at 13'20" with an arrow pointing at the Ly-a peak, with the drop-off - it's the edge of the cliff that's the thing - is there a way to clarify it with a set of simulations?
How did Hubble manage to measure the brightness of a star in Andromeda only using analogue technology? It always amazes me how pioneers in their fields managed these things without the technology we take for granted.
Not exactly a record breaking thing but something I thought after this video. I would kinda be interested in a video about the naming conventions about all of these? Can we make something out of the weird gibberish letters and numbers? For those objects that are just coordinates how do we read them in this constantly moving three (or four?) dimentional space? And when do we give objects "real" names?
So when will We reach the ''Stop'' sign saying: - Nothing more to see... Move along...? At some point the expansion rate must reach the speed of light...? Or the ''Sign'' saying: If you can read this... You're to close...
Would absolutely love more videos discussing records in astronomy. To many laymen, it is precisely the scale of the universe that draws people in.
Agreed. Isaac Asimov used to do essays like that, and they were fantastic. (Still are, but they're all many decades out of date.)
Agreed!

Excellent post Becky. Expertly told explanation of our Universe as currently understood . .
Thank you Dr Becky for a whirlwind tour of history. Question please: What if we find a galaxy with redshift of more than 14 billion years? Will that mean we "age" the universe a little older?
what if … what if 1+1=3. If you found an object in universe redshifted more than cosmic microwave background then you have to redo the whole theory.

You haven’t done much on neutrino astronomy, which is understandable because it’s kind of in its infancy. Still, we have piles of data from many sources. What do you think the future of neutrino astronomy will look like? Will we ever get a map of the Cosmic Neutrino Background Radiation? If so, do you expect it to match up at all with the CMBR maps?
Video suggestion... video on how the age of the universe has altered over the years and why that was. Thanks
Please make a series and i love your videos sooo much❤❤❤ also i just have to say, the bloopers😂
Thank you,Dr. Becky for that illuminating discussion, even if it was mostly in the IR spectrum and thus not visible to the human eye. 🙂
In the original Star Trek - about 1967 - they had an episode "The Galileo Seven" where there was a quasar and THEY gave it a name. Murasaki 312!
Love the idea about a record breaker series
And we used to think that we were the center of it all and that we were important 😂
Well we once were. In a way we still are, but that is difficult for people to comprehend 😘
Some people still consider themselves the center of the universe! 🙄
Well, we don't have to be BIG or a center in order to be important for ourselves. I'd rather than pitying about how small we are be glad about how big the Universe is.
We are at the center of everything this planet will ever interact with, though.
You and everyone else is quite literally always at the center of the universe - the center of the visible universe, that is :)
Great video, thank you Dr Becky. The graphic at 13'20" with an arrow pointing at the Ly-a peak, with the drop-off - it's the edge of the cliff that's the thing - is there a way to clarify it with a set of simulations?
Fun fact: The galaxies get their designations from the model numbers on Walmart coffee makers.
I like the "Most" videos idea. I am still mesmerized by the Morn 1415 video of black hole sizes up to TON 618. Good God!!
I love the Record Breakers idea. I suggest you call it Universe Superlatives.
Definitely make this a series! Maybe one of these every few months 😁
How did Hubble manage to measure the brightness of a star in Andromeda only using analogue technology? It always amazes me how pioneers in their fields managed these things without the technology we take for granted.
Dr.Becky rocks!!!!!
What an awesome video one of the best you have done
Thanks 😊.
Not exactly a record breaking thing but something I thought after this video. I would kinda be interested in a video about the naming conventions about all of these? Can we make something out of the weird gibberish letters and numbers? For those objects that are just coordinates how do we read them in this constantly moving three (or four?) dimentional space? And when do we give objects "real" names?
Ooh! Becky shows her bloopers! THE DOCTOR IS A HUMAN! 💖
Do it, I love the idea of Record Breakers or Tier List, whatever, but these lists are great!
Dr. I been listening to you for a while. Very interesting
Thanks, Dr. Becky~
This research would make a great annual review! think about it.
So when will We reach the ''Stop'' sign saying: - Nothing more to see... Move along...?
At some point the expansion rate must reach the speed of light...?
Or the ''Sign'' saying: If you can read this... You're to close...
I do like this sort of greatest hits videos. And I agree it is one of your best
I agree one of the best you've made 😊
