Plus, our viewers get 20% off an annual Premium subscription for unlimited daily access to everything Brilliant has to offer Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the elusive graviton—the quantum particle of gravity—whose discovery will finally allow us to stitch together our two great theories of nature into a single master theory. But what is the graviton, and does it even exist?

    What If The Cosmological Constant Wasn't Truly Constant?

    Weathered: Earth's Extreme is available globally at: https://to.pbs.org/WeatheredST or the PBS App (US Only) Check out the Space Time Merch Store https://www.pbsspacetime.com/shop We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard assumption is that the acceleration rate is itself constant, which will surely result in ultimate heat death. But a recent survey of primordial sound waves frozen into the way galaxies are sprinkled through the universe reveals that this fate is now in question. PBS Member Stations rely on viewers like you.

But we have few qualms about sending robots on one-way suicide missions to the stars. And in some cases, the very destruction of these probes is part of the scientific experiment. Or in the case of the recent destruction of Cassini, to protect the solar system for future experiments.

Also on Amazon: https://noviumdesign.shop/crQH4A 2025 is … was the international year of quantum science and technology. 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.

You were told wrong. In a sense. We can define a boundary to an infinite universe, at least mathematically.

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.
