      Olber's Paradox is one of my favorites. I watched another video many, many years ago on the topic and I use its ideas routinely to bait hard-headed young-earth creationists into a science discussion that leads to them accepting that the Big Bang(or one of them anyway) happened billions of years ago.

      I certainly feel it is lots of ideas for 10ish minutes which isn’t wrong obviously but Smarter Everyday in particular talks about how this is challenging for RUclips algorithms or whatever as I think I tweeted you... also, as I mentioned for instance on the latest Tibees I have a very unusual mind AND definitely science/math/tech RUclipsrs however defined certainly do too I’d argue - one aspect outside of purely technical content is that it is fairly dark/night like of an episode which is appropriate but perhaps overwhelming to many viewers however perceived!? - maybe also even more panning across various skyscapes etc would be drawing viewers in and along with you and the comprehension gaps they may have encouraging them to watch again as happened for instance for myself when I watched this Cool Worlds episode over a year after I first watched it ( m.ruclips.net/video/b_TkFhj9mgk/видео.html ) and was able to connect it in my comprehension (as I wrote about in the comments shortly after you uploaded this to RUclips) in a weird way to this latest offering from you - the goal of Cool Worlds is raising awareness of a laboratory that does exomoon and similar research whereas a more general RUclipsr probably is shooting for not necessarily a smash hit very occasionally but more steady interest and learning and so on however perceived... also I’m curious about the rights issues I guess it was fair use the film clips in that Cool Worlds episode and yeah obviously Tom Scott knows the latest hahaha - anyway I certainly liked your latest here and it is definitely an unusual astronomical RUclips and that is excellent and who knows about RUclips metrics and so on - Hollywood studios do focus groups for their largest budget stuff I guess and occasionally even give a broad release to something that doesn’t have extremely positive focus group data however derived - the art and science of show business wow teaching/learning STEM etc is an exciting corner of it and thanks again for this episode in particular!🌌🌌🌌🌌🌌🚀🌈☮️💟🤯🎬

      That can also be the answer of how something comes out of nothing, you are assuming that it doesn't, that's a rule, and there's no rules, there's nothing, so it just can, therefore 0 becomes 1. (at least this works in homotopy type theory, as a basic axiom to create the rest of the entire mathematics).

    • @simesaid
      @simesaid 3 года назад +2

      @@Ozelea 🙋🏻‍♂️Hi Abubaker, you definitely should! You could also play around with the structure and phrasing a little (even though Jade's delivery was excellent), if you wanted to that is. For example: "*Nothing* can travel faster than the speed of light...Except...Nothing, which *can* travel faster than the speed of light...In fact because *nothing* can travel faster than the speed of light it means that *nothing* else is faster than *nothing* when it comes to cosmic speeds - *not one thing*!" Or any variation you like really. A few other cool facts are that the speed of light isn't really about the speed of light. It's just the fastest speed that any information can be communicated between any two things. Light travels at that speed simply because it's a massless particle, and all massless particles *must* travel at that speed. It's our universes law. To give an idea of the vastness of cosmic scales you could try giving the speed in km/h or mp/h for a bigger 'wow' factor - and then tell your class how long it would still take them to reach the next nearest star or galaxy! But, interestingly, for an individual photon of light that long journey would seem to pass in precisely no time at all. Because for anything travelling at that speed time just completely stops - you would arrive in the Andromeda galaxy without noticing even the tiniest fraction of a nanosecond having elapsed. That long, long, long journey would feel like...*Nothing*🤦🏻‍♂️! Good luck with the project 💁🏻‍♂️✨

  • @brindlebucker4741
    @brindlebucker4741 2 года назад +2

    Absolutely deadly effective demonstration of Doppler Effect! Seeing a demonstration like that makes it readily apparent and practically eliminates the need for a lengthy explanation. I wish there were more easy to grasp demonstrations like this because I think it would have and would have had a huge impact on the general public's understanding of science in general.
    I think, too often, the average person might have a good intuitive understanding in their own mind about something that they have integrated into their knowledge base, but when some science sceptic or a child asks them: Explain this to me so I can understand, they might struggle to do so because they lack easily replicated demonstrations like this. Imagine just being able to put water in a bathtub or basin and show Doppler Effect in a way that you can SEE it, rather than asking someone to first imagine what the sound waves of an ambulance siren might look like. Seeing is so important to humans for us to understand something. Seeing, for us, often produces that 'Eureka!' moment. You still might not be able to explain it, but you GET IT! and you get it immediately.
    This is great stuff, and if you do nothing else with your channel but simply spread this demonstration like a meme, you will have contributed greatly to your fellow human's understanding of key scientific and cosmological concepts/theories.
    Keep up the great work!

    6:14 Our whole universe was in a hot, dense state
    Then nearly fourteen billion years ago expansion started, wait
    The earth began to cool, the autotrophs began to drool
    Neanderthals developed tools
    We built a wall (we built the pyramids)
    Math, science, history, unraveling the mysteries
    That all started with the big bang (bang)
    Since the dawn of man is really not that long
    As every galaxy was formed in less time than it takes to sing this song
    A fraction of a second and the elements were made
    The bipeds stood up straight, the dinosaurs all met their fate
    They tried to leap but they were late
    And they all died (they froze their asses off)
    The oceans and Pangea, see ya wouldn't wanna be ya
    Set in motion by the same big bang
    It all started with the big bang
    It's expanding ever outward but one day
    It will pause and start to go the other way
    Collapsing ever inward, we won't be here, it won't be heard
    Our best and brightest figure that it'll make an even bigger bang
    Australopithecus would really have been sick of us
    Debating how we're here, they're catching deer (we're catching viruses)
    Religion or astronomy (Descartes or Deuteronomy)
    It all started with the big bang
    Music and mythology, Einstein and astrology
    It all started with the big bang

    Wow, this horizon of the observable universe, behind which nothing can "escape" to reach the earth (our center of perception), this reminds me quite a lot of the event horizon of a black hole, where also nothing can escape, not even the light....could it be that the expansion of space-time is basically something like an inverse of a black hole? And what implications would that have?

    • @l00d3r
      @l00d3r 3 года назад +3

      Einstein's General Theory of Relativity also predicts the existence of white holes, which are the opposites of black holes. Even though a white hole has never been observed, I sometimes think that maybe the Big Bang was a white hole event. I sometimes also think that as black holes evaporate due to Hawking Radiation, that they might turn to a white hole when a critical mass is reached and it can no longer stay a black hole. At that point, the gravitational force can no longer overcome the repulsive forces of matter particles and energies inside, sort of like a supernova. These are just thoughts, though.

Today, RUclips suggested this video to me and I said to msyself: "Hey, that was the paradox from that guy...! Was it Oorst? Dilbert? Obsert?" And now, after all this time, I've found that I already knew all the elements of the solution, but never assmebled them to get the correct answer!

    9:32 Are you sure about this? It reminds of the 'Ant on a rubber rope' (en.wikipedia.org/wiki/Ant_on_a_rubber_rope) puzzle with the counter-intuitive solution. The analogy is that basically light from every source will eventually reach us, given enough time.

      I'll take explicit pitches by RUclipsrs over repetitive ads chosen by Google executives every time I'm offered. But yeah it's got a strange 50s-TV feel to it then they cut to a sponsor promotion, even when Adam Ragusea does it, and he has all but mastered the art of the sponsorship segue.

    If the universe is expanding and the expanding speed is rising (because of dark energy) doesn't that mean that eventually that speed will pass speed of light and then we won't be able to see stars we see now?meaning the visible universe will shrink?

    • @jursamaj
      @jursamaj 2 года назад

      Indeed, things slip beyond the horizon out of the visible universe all the time, we just don't notice it. And as expansion accelarates, this will happen more. See en.wikipedia.org/wiki/Cosmological_horizon especially the section on Hubble horizon.

    8:32 That's when I realized where she's going with it and what is the solution to paradox. I have developed a bad habit all these years using internet. I can't sit through any explanation over 2 minutes long and my mind become uneasy to find a quick summary. Any method to calm my nerves down?

    @qwerty_and_azerty 3 года назад +1

    I was a bit confused by the initial explanation of the paradox. I thought maybe the solution was that the sky is dark because our eyes/telescopes have limited resolution and limited exposure time. If photons from very distant objects only hit our sensors very occasionally, we won’t perceive their light, I thought. Isn’t this was the Hubble Deep Field experiment showed? That a dark patch of sky actually contains a lot of light if you significantly increase the exposure?

  • @Samurook
    @Samurook 3 года назад

    If the galaxies furthest away are receding fastest, doesn't that mean that they were receding from us a long time ago? How do we know that they are still receding from us at the rate they were receding when their light left on its journey towards us? What is the maths that shows that despite their being so distant in time, we "know" they are still receding more quickly than closer galaxies?
