Have you ever wondered how the James Webb Telescope could take a photo that's 13 billion years old? Or how light can reveal secrets from billions of years ago? In this video, I'm exploring the fascinating concept of the Doppler effect as it applies to light, known as redshift. By understanding redshift, and the expanding universe, scientists can peer almost 13.6 billion years into the past, observing the universe when it was just 2% of its current age.

I'll also be giving away an awesome Space Shuttle Lego set, so be sure to stick around until the end of the video to learn more about how you can win! Enter to win at the link below.

    Knowing there could potentially be life in those far away galaxies and that we could do nothing to stop them from moving away due to space's expansion just feels terrifying to me
  • @stelabouras
    That was an amazing and really easy to understand explanation of Redshift. Keep up the great work!👍
  • I think the quote by Arthur C. Clarke sums it up nicely.
    “Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.”
  • @lukeblignaut2445
    Can't wait for the James Web telescope to capture a million year old image of an alien flying by. That would be amazing.
  • @saahas1938
    James Web's discoveries are getting amazing day by day, the hard work of the scientist involved in this project has really paid off and thank you for the great explanation of expansion of universe and Redshift. 😃👏
  • Space is so cool to me, I’ve loved the thought that at one point in space you are far enough from earth you could see the exact moment the chicxulub meteor wiped out the dinosaurs, or you could go back and see the vesuvius eruption at Pompeii, space is so big that distance can become a sort of time travel
  • @bfb8063
    Strangely terrifying. But if you think about it, it's better to have a universe expanding outward than collapsing inward.
  • @silly_gooses2568
    the idea of life potentially being somewhere in this universe is scary but exciting. seeing what other creatures are like and how they could be completely different seems extremally fascinating
  • @pmrego
    I think that there is definitely life in our universe. The universe is big, very big and there are so many galaxies out there, so many possibilities. Life is not something that only happens once, it happens because of certain conditions being present and since the universe is so huge, there definitely is a chance of life happening in other planets. They (beings of other worlds) might be far away, young or dumb but there always is space for more life in the universe other than us.

    Also love the video ❤, very nice graphics and animation as well as helping me understand complex topics about light and our universe.

    Thanks for reading my comment 🙃
  • @clarkgourguejr
    For some reason, I've been more fascinated with these topics more and more lately. This video has done a fantastic job of visualizing and explaining the physics of our universe in a simplified way. Thanks!
  • @920jack
    It is absolutely mesmerizing just how enormous is the universe we live in. There is literally no way to wrap our heads around these vast distances and space. So big, yet appears so lonely.
  • I really love your channel and the way you explain. I always watch with my nine year old son, he finds it very entertaining and easy to understand. Keep up the good work. :)
  • @samcg1492
    I love JWST videos, its incredible the amount of things its capable of. Hyped about all the things it will teach us.
  • @CosmicExplorerX
    The idea of life existing beyond our world is a fascinating reminder of the endless mysteries waiting to be explored in the vastness of space.
  • @vipindas1
    Hats off to the engineers behind James webb Telescope. Its an engineering marvel
  • @TrueGamingVault
    Hey Primal, brilliant video as always, can I also mention recently The Telegraph Newspaper did an article about a new NASA rocket which will cut journey time to Mars in half. I think this would be an interesting topic to cover, especially because you're able to explain in a way us non-techical people can understand, the cookie explenation was 👌. 😅❤
  • @southeasteire
    I think life has got to exist. The universe is so big and old. I just might be so far away that we’ll never contact it :(
  • @Dr1z.
    This video deeply satisfied my curiosity about space... and the simplicity with which you explained everything us truely remarkable. I wish could've found this channel before, but better late than never. Thanks!
  • @AG-kc7fp
    I'm truly fascinated by how the basic principles of physics can lead to such incredible discoveries. It's truly remarkable how something so simple can unlock so much potential.
