The Cosmic Scale

How large is the universe? Where does it begin and end? And how does it expand? These are some of the biggest questions of astronomy. And while humanity is so small that we may never be able to fully understand the true scale of the universe, advancements in technology are helping us to look ever-deeper into the wilds of our existence- towards the edge of our observable universe, known as the Cosmic Horizon. Today, we will analyse the universe, its laws, and its awe-inspiring scale.

    Huge respect for the cameraman who traveled around the universe just to record this.
  • Using "bus size" to describe the Hubble telescope was definitely the most comprehensible unit of measurement in the whole video
  • @elmowilcox
    It’s always crazy to remember that every time you hear the unimaginable scale of the “observable” universe that there’s still an awful lot of unobservable universe out there.
  • @patriley9449
    I feel privileged to live at a time when these wonders are revealed.
  • @xGaLoSx
    I dont understand how this shit isn't all everyone thinks about and obsesses over everyday of their life.
  • @jharris7
    I enjoy thinking about how big the universe is because it makes my problems feel insignificant. There's so much comfort in that.
  • I will always remember the first time I saw the Hubble Deep Field image. It's one of those moments in life that changes your view forever.
  • @randomname8727
    No matter how many videos I watch or rewatch that discuss the sheer scale of the universe, I'll never get bored. Really passionate about it, even not a professional or anything, I will forever admire these topics until I can't.
  • @bkb04g
    “THE COSMIC SCALE” watched on a cell phone
  • @rickfowler273
    I think the universe holds things we can never fathom. And I think it’s way bigger than we can understand.
  • @Azdingue
    This has been one of the best videos about astronomy I've ever seen, it includes everything I've seen in every other video and the relation between it in a single video and is put together so elegantly and makes understanding it or finding the relation between different things I've known very easy and admirable . Thank you ❤
  • @JaYoeNation
    I think it’s important to watch content like this regularly. It’s grounding to see the bigger picture.
  • @bittech1
    You’re really good at getting just the right mix of casual depth and more advanced concepts into your videos. Gives the viewer room to research more into a topic, but also doesn’t lock them away behind a bit too much detail, or not enough to be interesting.
  • @a2j544
    I think the saddest part about the universe is how it's actively isolating us from everything else due to its rapid expansion. It's fascinating that the very process of creating more and more gives us less and less to observe
  • @pascalxus
    i've seen many presentations on this but this one is the best! Great Going!
  • @carbon_no6
    No matter how many times I view pictures showing “Hubble Deep-Field or Hubble Ultra Deep-Field” my mind is always melted by how impressive it truly is that those light-points in the photographs are entire galaxies!!
  • @jlc1637
    I came to YouTube stoned to watch funny videos and am leaving with an existential meltdown.
  • This channel is the best I have seen so far amongst all the ones that explain the concepts of the universe and space/time. The reason I like it the most is because the explanation is simple and clear, and the focus is on helping everybody understand the mysteries of the universe. What I particularly like about this channel is that it is focused on the facts supported by research, and there is no attempt to intersperse the explanation with needless, unnecessary music and over-dramatizing. In some channels, the loud music is sometimes so distracting that it actually takes away from the focus on the facts of the science. And I say this despite being an English Literature graduate, with no background in Science. If I could understand and appreciate it, I am sure anybody can. Thank you for this excellent channel and narration!
  • @nirmalkumar7941
    It's terrifying and yet comforting to know that the planet you lived on along with the galaxy and literally everything will be gone one day leaving no signs that something even existed . So it doesn't matter what you are or what you are doing or where you were born, just experience life with all the flaws and beauty and wave goodbye
