Subtle clues are emerging that the accepted model for the nature of dark energy and dark matter may not be all that. We saw the first such clue recently in our recent episode on the Crisis in Cosmology. Today we’re doing a Space Time Journal Club to reveal another clue. We’re looking at a new paper in Nature Astronomy, “Cosmological constraints from the Hubble diagram of quasars at high redshifts” by Risaliti and Lusso. It hints that the cosmological constant may not be so constant after all. In fact it may be increasing. If this is true, then our prediction for the future of our universe looks VERY different, and may involve the entire universe tearing itself to shreds at the subatomic level in the Big Rip.On this edition of Space Time Journal Club we look at:Risaliti and Lusso (2019) "Cosmological Constraints from the Hubble Diagram of Quasars at High Redshifts"https://www.nature.com/articles/s41550-018-0657-z#darkenergy #darkmatter #spacetimeMore about The Great Courses Plus: The Great Courses Plus is currently available to watch through a web browser to almost anyone in the world and optimized for the US, UK, and Australian markets.

There’s a limit to what we can ever hope to explore or send signals to, and a very different limit to what we can ever hope to witness. Today we’re going to explore the latter. We’re going to figure out the absolute limit of our future view of the universe, and of the universe’s ability to influence us. Next time we’ll turn it around and ask: how much of the external universe can WE potentially influence, and even explore?

The very, very long story short is that the universe ends in heat death, as it approaches maximum entropy, and its eternal exponential expansion drives it to effective utter emptiness and absolute cold. But new calculations have revealed we may be able to look forward to one last source of astrophysical cataclysms - a new type of supernova that can only happen at the end of the universe.

Not everything wows like gravitational waves or spacefaring sportscars. That’s the case with the recent discovery of earliest stars in the universe. In a Nature paper published a few weeks ago, Judd Bowman and collaborators report a signal from the very first stars to form in our universe. The same result also hints at brand new physics that may help explain the nature of dark matter. This result flew under the radar in part because it’s a subtle and clever result that requires a bit of interpretation. Today we’re doing a Space Time Journal Club to explain this discovery. We’ll follow that with the solution to our recent trebuchet challenge question.Written and Hosted by Matt O'DowdProduced by Rusty WardGraphics by Grayson BlackmonAssistant Editing and Sound Design by Mike Petrow and Linda HuangMade by Kornhaber Brown (www.kornhaberbrown.com)Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasFaisal SaudAnton LifshitsJoey RednerQuasarTambe BarsbayMayank M.

There are, of course, some differences. For example, these storms are as big as entire planets. The largest and oldest storm in the solar system is Jupiter’s Great Red Spot, stretching an incredible two to three times the diameter of the planet Earth. Meanwhile the fastest winds ever measured, clocking fifteen hundred miles per hour, once raged in Neptune’s Great Dark Spot. Saturn’s Polar Vortex is a 20,000-mile-wide monster shaped like a hexagon. Even plain-looking Uranus hides USA-sized hurricanes below its methane haze. There are many unsolved mysteries surrounding these epic storms. We may be close to finding some answers, following the Juno spacecraft’s recent flyby of Jupiter’s Great Red Spot.Juno's interactive website: https://www.missionjuno.swri.edu/Written by Alexandra Yep and Matt O’Dowd Hosted by Matt O' DowdProduced by Rusty WardGraphics by Kurt RossAssistant Editing and Sound Design by Mike PetrowMade by Kornhaber Brown (www.kornhaberbrown.com)Comments answer by Matt:Andres64 https://www.youtube.com/watch?v=9dqtW...Keith Gaughanhttps://www.youtube.com/watch?v=9dqtW...Vacuum Diagrams https://www.youtube.com/watch?v=9dqtW...youteub akount https://www.youtube.com/watch?v=9dqtW...Don Solaris https://www.youtube.com/watch?v=9dqtW...Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasQuasarTambe BarsbayMax LevineMayank M.

They make it possible to solve physics problems that would otherwise be painfully difficult, or even impossible. More than cheat codes – conservation laws are close to the source code – they emerge from profound and simple truths about the basis of reality. They emerge from the fundamental symmetries of nature. The connection between conservation laws and symmetry is encapsulated in Noether’s theorem.

We can’t determine the values of these constants from pure theory - we have to measure them in the real universe. These are things like the speed of light, the Planck constant, the masses of the elementary particles, and the constants defining the relative strengths of the fundamental forces - the so-called coupling constants.Special Thanks to Our Patreon SupportersBig BangAlexander TamasCraig StonahaDavid BarnholdtDavid NicklasFabrice EapJohn SJuan Benetmatt millerMorgan Hough QuasarMark HeisingMark RosenthalVinnie Falco HypernovaChuck ZegarDanton SpiveyDonal BotkinEdmund FokschanerHank SJohn HofmannJohn R.

In short: in a galaxy of hundreds of billions of stars, each of which having billions of years to spawn life and civilization, isn’t it odd that none have made themselves apparent to us. Enrico Fermi was, supposedly, using this as an argument against the plausibility of interstellar travel. If aliens can travel between the stars, why haven’t they visited? But the paradox is much broader than this. There are several ways that an advanced civilization could give away their presence. Radio transmissions, robotic probes, or star-blotting solar arrays. A series of very recent surveys of our galaxy reveal none of the above, while at the same time proving the abundance of potentially habitable worlds. The Fermi paradox has become only more paradoxical, and these surveys are finally powerful enough to draw some serious conclusions about the rarity of advanced civilizations AND about the chance of us ever becoming one.Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangJustin LloydAnton LifshitsCoolAsCatsDavid NicklasFabrice EapJuan BenetQuasarDean FuquaJames FlowersMark RosenthalRoman PinchukTambe BarsbayVinnie FalcoHypernovaChuck ZegarDan HarrisDonal BotkinEdmund FokschanerJohn HofmannJordan YoungJoseph SalomoneMartha HuntMatthew O’ConnorRatfeastThanks to our Patreon Gamma Ray Burst Supporters: Alexander RodriguezAlexey EromenkoBrandon CookBrandon LabonteDaniel LyonsDavid CraneFabian OlesenFauzan ArdhanaGreg AllenGreg WeissJack FroschJames HughesJJ BagnellJon FolksJoseph EmisonJosh ThomasKevin WarneMalte UblMark VasileNathan LenizNicholas RoseNick VirtueScott GossettShannan CatalanoShawn AzmanTommy Mogensenسلطان الخليفي Learn more about your ad choices.

Labels help us keep stuff organized in our heads. In science, categorization provides a fast and easy way to know the properties of a member of the group just by knowing what group it belongs to. Chemists group elements on the periodic table, those groups exhibit similar chemical behavior that reflect outer-shell electron number. Biologists group organisms by similar physical characteristics, and this taxonomy reflects genetic relationships. Astronomers are all about space taxonomy. We classify galaxies based on their shape, black holes based on how they feed, stars based on their colour and brightness, and planets by… well, by a set of criteria that has caused more tension and heartbreak than any made-up grouping scheme really should. Because a change in that scheme demoted Pluto from planet to not-planet. Today we’re going to settle whether this was reasonable, and whether we should keep the word “planet” at all.Big Bang Supporters:Alexander TamasAnton LifshitsDavid BarnholdtDavid BoyerDavid NicklasFabrice EapJuan BenetJustin LloydMatt MillerMorgan HoughQuasar Supporters:Mark HeisingMark RosenthalVinnie FalcoHypernova Supporters:Chuck ZegarDanton SpiveyDonal BotkinEdmund FokschanerHank SJohn HofmannJohn R.

But in the real universe gravity appears to be a purely attractive force. Feels like its main MO is keeping us stuck to the surface of this lonely rock. But maybe if we science hard enough we can remove the fiction from science fiction. For the sake of our flying cars we should at least try. And for many years, physicists have wondered whether a certain well-known exotic material may experience gravitational repulsion from the Earth. That material is antimatter, and physicists at CERN have just completed a very long and very difficult experiment to answer a seemingly simple question: does antimatter fall down, or does it fall up?

In recent years it’s become clear that the truth is even more mind-blowing. Many heavy elements - includes most precious metals - were produced in an even more spectacular event: the collision of neutron stars. In fact, according to a recent study most of the Earth’s supply of these elements was created in a single neutron star merger that took place near our Sun’s birth nebula 80 million years ago before Earth formed.

And that the elements heavier than iron were synthesized in the following supernova explosion. That latter process is well understood – the star’s dead core collapses and protons are converted to neutrons. The surrounding shells ricochet outwards, along with a layer of the iron and nickel core. The latter is blasted by a wave of neutrons, which get rammed into the escaping nuclei. Some of those captured neutrons convert back to protons and so elements all the way up the periodic table can be made. This is the rapid neutron capture or r-process. The rapid part is because neutrons are captured faster than nuclei can decay, making it possible to build very heavy nuclei.Big Bang Supporters:Anton LifshitsDavid NicklasFabrice EapJuan BenetJustin LloydQuasar Supporters:Mark HeisingMark RosenthalTambe BarsbayVinnie FalcoHypernova Supporters: Chuck zegarDanton SpiveyDonal BotkinEdmund FokschanerHank SJohn HofmannJordan YoungJoseph SalomonekkmMark HeisingMatthewMatthew O'ConnorGamma Ray Burst Supporters: Adrien HatchAlexey EromenkoAndreas NautschBradley JenkinsBrandon LabonteCarlo MogaveroDaniel LyonsDavid BehtalaDFaulkDustan JonesGeoffrey ShortJames FlowersJames QuinteroJohn FunaiJohn PollockJonahJonathan NesfederJoseph DillmanJoseph EmisonJosh ThomasKevin WarneKyle HoferMalte UblMark VasileNathan HitchingsNick VirtuePaul RoseRyan JonesScott GossettSigurd Ruud FrivikTim JonesTim StephaniTommy MogensenYurii Konovaliukسلطان الخليفي Learn more about your ad choices.

To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity. And to do that, most physicists believe we need a theory of quantum gravity .. which means we need gravitons. But it also seems like the laws of physics make it impossible to ever detect this quantum particle of gravity. Almost like the universe is set up to keep the final answer forever out of our reach. So, can we outsmart the universe, catch a graviton, and finally solve physics?

The second law of thermodynamics – the law that entropy must, on average, increase – has been interpreted as the inevitability of the decay of structure. This is … misleading. As we saw in our episode on the physics of life, structure can develop in one region even as the entropy of the universe rises. Ultimately, entropy is a measure of the availability of free energy – of energy that isn’t hopelessly mixed in thermal equilibrium. Pump energy into a small system and complexity can thrive..

Yes because quantum tech is increasingly important, but especially because quantum mechanics was invented 100 years ago this year. In 1925, our strangest true theory went from being a peculiar set of ideas to describe some funny results from experiments, to a full-blown theoretical framework that overturned how we think reality really works. So today, as the centenary year approaches its end I want to take you on a little journey through what may be the most paradigm-destroying several months in scientific history.

In order to wrap our puny human minds around such a notion we like to come up with boundaries. For example we have the “observable universe” – that patch that we can see, and beyond which light has not yet had time to reach us. It’s boundary is called the particle horizon. Beyond it there exists at a minimum of thousands and possibly infinitely more regions just as large. Our observable universe is like a tiny patch of land in a vast plain. We define its horizon like we might build a little picket fence around our little patch – meaningless from the point of view of the plain, but it makes our patch feel more homey and us less crushingly insignificant.Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big Bang:Anton LifshitscoolascatsDavid NicklasFabrice EapJuan BenetJustin LloydTim DavisQuasar:James FlowersMark RosenthalTambe BarsbayVinnie FalcoHypernova: chuck zegarDanton SpiveyDonal BotkinEdmund FokschanerJens TheisenJohn HofmannJordan YoungJoseph SalomonekkmMark HeisingMatthew O'ConnorThanks to our Patreon Gamma Ray Burst Supporters: Alexey EromenkoAndreas NautschAntonio RuizBradley JenkinsBrandon LabonteBuruk AregawiCarlo MogaveroDaniel LyonsDavid BehtalaDavid CraneDavid SchmidtDustan JonesGeoffrey ShortGreg WeissJack FroschJames HughesJames QuinteroJinal DoshiJJ BagnellJohn WebberJon FolksJonahJoseph EmisonJosh ThomasKenneth F LeonardKevin WarneKyle HoferMalte UblMark VasileNathan HitchingsNicholas RoseNick VirtueRatfeastRichard BromanScott GossettSigurd Ruud FrivikTim CrookhamTim StephaniTommy Mogensenسلطان الخليفي Learn more about your ad choices.

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.

Ha, who am I kidding. It turns out they may be responsible for ending star formation across the entire universe.Hosted by Matt O'DowdWritten by Matt O'DowdGraphics by Leonardo ScholzerDirected by Andrew KornhaberProduced By: Kornhaber BrownWhen we first realized that black holes could have masses of millions or even billions of times that of the sun, it came as a bit of a shock. They were discovered as the driving force behind quasars, where matter is heated to extreme incandescence before its plunge into vast black holes. But if that weren’t enough, we soon realized that every single decent-sized galaxy contains such a supermassive black hole. By the beginning of the 21st century it became clear that black holes and the galaxies that contain them are very closely connected. The bigger the galaxy, the bigger its supermassive black hole. That might not sound surprising. What was weird was how closely they were connected. There’s a tight correlation between the mass the central black hole and the mass of the stars in the galactic bulge – that’s the central ball-like part of a spiral galaxy, or the entirety of an elliptical galaxy, and every bulge contains a supermassive black hole around one-one-thousandth its mass. And there’s an even tighter relationship between the black hole mass and the speed that stars are moving in their random orbits within the galactic bulge – the so-called stellar velocity dispersion – which itself depends of the total mass of the galaxy, including dark matter.Big Bang Supporters:Anton LifshitsDavid NicklasFabrice EapJuan BenetJustin LloydQuasar Supporters:Mark HeisingMark RosenthalTambe BarsbayVinnie FalcoHypernova Supporters:Chuck ZegarDanton SpiveyDonal BotkinEdmund FokschanerHank SJohn HofmannJohn R.

Please subscribe to Brian Keating's YouTube Channel to watch one-on-one interviews with the guest speakers and more: https://www.youtube.com/DrBrianKeating July 28 @ 4pm Eastern (8pm UTC) - What is a Theory of Everything? Moderated by Matt O'Dowd & Brian Keating Featuring Max Tegmark, Stephon Alexander, James Beacham In this 90 minute conversation we explore what Theories of Everything really are outside the hype, dig into the essential physics mysteries that compel us to search for one, and survey the major TOE contenders currently being explored by the physics community. August 4 @ 10:30am Eastern (2:30pm UTC) - Theory of Everything Controversies Moderated by Matt O'Dowd & Brian Keating Featuring Lee Smolin, Eric Weinstein, Sabine Hossenfelder Existing Theories of Everything have not yet produced experimental evidence that solves the fundamental challenges facing physics. That lack of progress has opened up a sea of controversy, from disagreements about the very necessity of TOEs, to questioning the cost/benefit of mega-billion dollar particle accelerators in search of them, to the emergence of competing TOEs from physicists outside of the academic community. In this 90 minute chat we dive into the existential questions around TOEs. Learn more about your ad choices. Visit megaphone.fm/adchoices

Finally, two powerful and independent methods have refined its measurement to unprecedented precision. The only problem is that they don’t agree. This calls into question some of our most basic assumptions about the universe.Tweet at us! @pbsspacetimeFacebook: facebook.com/pbsspacetimeEmail us! pbsspacetime [at] gmail [dot] comComment on Reddit: http://www.reddit.com/r/pbsspacetimeHelp translate our videos!https://www.youtube.com/timedtext_csPrevious Episode: Why String Theory Is Wronghttps://youtu.be/IhpGdumLRqsHosted by Matt O'DowdWritten by Matt O'DowdGraphics by Luke MaroldiDirecting by Andrew KornhaberIn 1929, Edwin Hubble discovered the universe. 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.Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangAnton LifshitsCoolAsCatsDavid NicklasFabrice EapJuan BenetJustin LloydTIm DavisQuasarDean FuquaJames FlowersMark RosenthalTambe BarsbayVinnie FalcoHypernovaChuck ZegarDanton SpiveyDonal BotkinEdmund FokschanerJens TheisenJohn HofmannJordan YoungJoseph SalomoneMark HeisingMatthew O’ConnorThanks to our Patreon Gamma Ray Burst Supporters: Alexey EromenkoAntonio RuizBradley JenkinsBrandon LabonteBuruk AregawiCarlo MogaveroDaniel LyonsDavid BehtalaDavid CraneDavid SchmidtDustan JonesGeoffrey ShortGreg WeissJack FroschJames HughesJames QuinteroJinal DoshiJJ BagnellJohn WebberJon FolksJonahJoseph EmisonJosh ThomasKenneth F LeonardKevin WarneKyle HoferMalte UblMark VasileNathan HitchingsNicholas RoseNick VirtueRichard BromanSammy JScott GossettSigurd Ruud FrivikTommy Mogensenسلطان الخليفي Learn more about your ad choices.

Release this energy and you have, well, you have a nuclear explosion. Just as well there's an even stronger force than the electromagnetism holding our nuclei together. But it's not the strong force, as you might have imagined. At least not directly. Nuclei are held together by a quirk of nature, without which we would have no complex atoms, no chemistry, and certainly no labradoodles.
