  Does Space Materialize From A Holographic Boundary? 02.10.2026 20min

  Check out the Space Time Merch Store https://www.pbsspacetime.com/shop Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetime Space seems fundamental. To build a universe, surely you need something to build it on or in. Many, maybe most physicists now think that the fabric of space emerges from something deeper. And perhaps the most existentially disturbing such proposal is that our 3-D universe is just the inward projection of an infinitely distant boundary. A hologram, or sorts. Let’s see how that can actually work, and what the holographic principle really says about the “realness” of this universe.

Finally, two powerful and independent methods have refined its measurement to unprecedented precision. The only problem is that they don’t agree.

He gave us our first incontrovertible proof that there are galaxies outside the Milky Way by measuring the distances to the spiral nebulae. They were many millions of light years from us –far outside the Milky Way and so must be galaxies in their own right. Combined with the Doppler-shift velocity measurements of Vesto Slipher, Hubble revealed that the galaxies are not only receding from us, but they are receding at a rate proportional to their distance.

  What Happens If A Black Hole Hits Earth? 02.10.2026 26min

  Check Out Above The Noise: https://youtu.be/GKS3ph3G2jc Take the Space Time Fan Survey Here: https://forms.gle/wS4bj9o3rvyhfKzUA The possibility that a black hole could actually impact Earth may seem straight out of science fiction, but the reality is that microscopic primordial black holes could actually hit Earth. If one did, it wouldn't just impact like an asteroid, it'd pass straight through the entire Earth and exit the other side. Perhaps craziest of all, this may have already happened! ***** PBS Member Stations rely on viewers like you.

And that about covers the universe: matter moving through space and time under the action of forces. But what if we could create particles in between these two possibilities. Physics says these neither matter nor force anyons can exist, and they may have some pretty incredible uses. They’re called anyons. PBS Member Stations rely on viewers like you.

  Check out the Space Time Merch Store https://www.pbsspacetime.com/shop Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetime Two of the greatest mysteries in cosmology are the nature of dark energy and the apparent conflict in our measurements of the expansion rate of the early versus the modern universe that even dark energy can’t account for.

Historically, no matter how crazy our theories got, there were always new ways to test them. Your theory predicts a new particle? Build a particle accelerator big enough to see it. But once your collider spans entire countries – like the Large Hadron Collider in Switzerland – there’s only so much larger you can go - at least on the surface of the Earth. The LHC has thoroughly tested the standard model of particle physics. The last component of that model – the Higgs boson – was verified in 2013. But the standard model isn’t the end of the story – there MUST be a more fundamental theory that explains the origins of this rich family of particles. Proposals for such grand unified theories proliferate, unconstrained by even the tiniest hint of new physics from the LHC. Help translate our videos! https://www.youtube.com/timedtext_cs_...

They were independently studying how the nature of quantum fields appears to change depending on whether or not an observer is accelerating. They found that simple act of acceleration cuts off your causal access to a region of the universe. It creates a type of event horizon. As we saw in our episode on horizon radiation, the presence of horizons distorts the quantum vacuum in a way that can create particles.

Many physicists believe that the answer lies in a process known as quantum decoherence. Hosted by Matt O'Dowd Written by Matt O'Dowd Graphics by Leonardo Scholzer, Yago Ballarini, & Pedro Osinski Directed by: Andrew Kornhaber Executive Producers: Eric Brown & Andrew Kornhaber End Credits Music by J.R.S. Schattenberg: https://www.youtube.com/channel/UCRl6-nb4iOnsij-vnpAjp0Q Does conscious observation of a quantum system cause the wavefunction to collapse? The upshot is that more and more physicists think that consciousness - and even measurement - doesn’t directly cause wavefunction collapse. In fact probably there IS no clear Heisenberg cut. The collapse itself may be an illusion, and the alternate histories that the wavefunction represents may continue forever. The question then becomes: why is it that we can see these multiple histories play out on the quantum scale, and why do lose sight of them on our macroscopic scale? Many physicists believe that the answer lies in a process known as quantum decoherence. Thanks to our Patreon Supporters!

More than all of the stars, all of the gas, all of the black holes…unless dark matter is black holes, then black holes are most of everything. Dark matter constitutes 80% or so of the mass in the universe, which means even our Milky Way galaxy is mostly a vast ball of dark matter that happens to have attracted a relative sprinkling of baryons—atoms in the form of gas, which lit up as starry glitter spinning in the middle of this invisible gravitational well.

Well, the 2023 Nobel prize in physics has been awarded to three physicists for opening just such a new window—but it's not a window to a new size scale or a new mode of seeing—-it’s for a new window in time. It’s for attosecond physics—the billionth of a billionth of a second that represents the timescale of the insides of atoms.

  Why Quantum Information is Never Destroyed 02.10.2026 18min

  Viewers like you help make PBS (Thank you 😃) . Support your local PBS Member Station here: https://to.pbs.org/DonateSPACE If you have perfect knowledge of every single particle in the universe, can you use the laws of physics to rewind all the way back to the Big Bang?

Previous Episode: Noether's Theorem and The Symmetries of Reality https://www.youtube.com/watch?v=04ERSb06dOg&t=2s The laws of physics are equations of motion. They are mathematical rules that dictate how systems evolve in time. Newton’s equations for classical mechanics, Maxwell’s equations for electromagnetism, and the Schrodinger equation for quantum mechanics. These laws can be used to predict how the universe will evolve into the future. They are deterministic; perfect knowledge of a system in the present perfectly predicts how the system will change in the next instant, and the instant after that, ad infinitum. But determinism in the forward-time direction does NOT guarantee that the same laws can perfectly predict the past. And yet this sort of deterministic symmetry - time-reversal symmetry - is essential for information itself to be conserved. Today we learn why conservation of information is such a fundamental requirement of quantum mechanics. In a future episode we’ll see how this law might be broken by black holes. Here's that fun proof that independent quantum states can't evolve into the same quantum state while preserving unitarity! Apologies for the unavoidable technical notation, but a quick college course in introductory quantum mechanics will get you up to speed in no time :-P http://bit.ly/2Lpm6sL Hosted by Matt O'Dowd Written by Graeme Gossel and Matt O'Dowd Graphics by Grayson Blackmon Assistant Editing and Sound Design by Mike Petrow and Linda Huang Made by Kornhaber Brown (www.kornhaberbrown.com) Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big Bang CoolAsCats David Nicklas Anton Lifshits Joey Redner Fabrice Eap Quasar Tambe Barsbay Mayank M.

What exactly is so compelling about tiny, vibrating strings? In our last string theory episode I talked about what these things really are, and covered some history. In short: the strings of string theory are literal strands and loops that vibrate with standing waves. Simply by changing the vibrational mode you get different particles – analogous to how different vibrational modes on guitar strings gives different notes. And, by the way, strings exist in 6 compact spatial dimensions on top of the familiar 3.
