We live in a universe with 3 dimensions of space and one of time. Up, down, left, right, forward, back, past, future. 3+1 dimensions. Or so our primitive Pleistocene-evolved brains find it useful to believe. And we cling to this intuition, even as physics shows us that this view of reality may be only a very narrow perception. One of the most startling possibilities is that our 3+1 dimensional universe may better described as resulting from a spacetime one dimension lower – like a hologram projected from a surface infinitely far away.

The holographic principle emerged from many subtle clues – clues discovered over decades of theoretical exploration of the universe. Over the past several months on Space Time, we’ve seen those close clues, and we’ve built a the foundations needed to glimpse the true meaning of the holographic principle. We’ve moved from quantum field theory to black hole thermodynamics to string theory. We’ve made a background playlist if you want to start from scratch, and I especially recommend catching last week’s episode. But this is tough material, so let’s do a review.

    It’s amazing what we can do with the same brains we used to throw stones at each other.
  • @lyndensmall1577
    Who ever did the music and animations of this episode deserves a raise
  • @Casey9256
    ‘Wait, what’ rewinds 3 seconds later. ‘Wait, what’ rewinds
  • @TrebleWing
    There is something very reassuring about not following 99.999% of this. Just knowing that someone out there understands this, and is in fact advancing this sort of math/research means there are still people out there that are passionate and talented enough to tackle the universe.
  • @pipoygarapon
    The only part of the video that i understand is when he tried to sell merch.
  • @bradyvelvet9432
    One of these days Matt will troll us with something totally fictitious and we won’t even know it 😂😂😂
  • You have really outdone yourself in this video. The level of complication you have simplified for us is astounding. Thankyou for bridging the gap from prohibitively complex to a more understandable format. You have enabled normal people to have a chance to grasp what we could otherwise probably never deciphered . Great work and thankyou.
  • So I needed to understand this, so I watched the playlist. But that required another playlist. Of which the very first video required a different video, which recommended that I also watch a different video. I now have 2.5 hours of Space Time to watch
  • @travisheck5979
    I love how you end every single discussion with "spacetime"
  • @kashfuleman6441
    ive been watchin you since i was in highschool and back then i coudnt understand most of it but now im an undergrad physics student and starting my final year project in quantum mechanics. watching your vedios on any topic before reading a paper gives me a baseline and a boost of confidence. you are saving a lot of my time and keeping me engaged in reserach with all your visuals so i dont get lost in math. its my go -to channel to entertain myself after getting bored with colorless reserch papers
  • respect to PBS for trying to make material like this available. Obviously you're not going to get a crystaline understanding of subjects like this in 20 meager minutes, but it's a great place to start!
  • @bjarnivalur6330
    Yup. I think I'm gonna need to watch this series a couple more times to get this.
  • @nikanj
    When you feel completely on top of a lecture and go to the bathroom and somehow come back two semesters behind.
  • @garrylowther
    My research into quantum computing led me here. As Heisenberg famously said, "not only is the universe stranger than we think, it is stranger than we can think". I look forward to more enlightenment of physics, brilliantly explained and visualised in these videos.
  • @m0L3ify
    "Over the past few months on Space Time ... we've built the foundations needed to glimpse the true meaning of the holographic principle." Me tuning in to this video randomly: Oh shit, I just walked in to the final without ever going to class... 😰😨😰
  • @tinunit
    This video proved I'm dumb in every dimension.
  • @jjfg3960
    I'm doing a project on black hole entropy for my thermodynamics course, and these videos have actually carried me so hard. Thanks!!!!!
