No headset? No problem. Move your mobile phone around and catch the total 180 experience. Have fun looking down from the catwalk! How can you build a telescope that can see the entire night sky without moving its dish? Well in this special episode of Space Time we took a tour of the Arecibo Observatory with a VR 180 camera so you could explore the incredible ingenuity of Arecibo's giant spherical dish that allows it to reflect light from every spot on the sky in a symmetric way. We also talked to Dr. Abel Méndez about Exoplantes and Aliens!

It’s the key to faster than light travel because it’s the only stuff that can curve space in the right way to hold open wormholes and construct warp fields. And if you can travel faster than light you can also travel backwards in time. We’ve been over those already. And we also recently covered a very new use for negative mass: as “dark fluid”, a proposed explanation for both dark matter and dark energy. That episode really got me thinking about the subtleties of negative mass and how it should really behave gravitationally. Turns out it’s complicated, and to answer it we really have to question the very definition of mass.Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangAnton LifshitsCoolAsCatsDavid NicklasFabrice EapJuan BenetJustin LloydTIm DavisQuasarJames FlowersMark RosenthalTambe BarsbayVinnie FalcoHypernovaChuck ZegarDanton SpiveyDonal BotkinEdmund FokschanerJens TheisenJohn HofmannJordan YoungJoseph SalomonekkmMark 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 VirtueRatfeastRichard BromanSammy JScott GossettSigurd Ruud FrivikTim CrookhamTim StephaniTommy Mogensenسلطان الخليفي Learn more about your ad choices.

Check Out Megawow on PBS Kids: https://youtu.be/meU4f31gqYI Uploaded 10-08-21In the Many Worlds interpretation of quantum mechanics, the universal wavefunction is the reality, encompassing all possible histories and futures and all exist. But we are only sensitive to a slice of the wavefunction corresponding to our “world”, and due to the superposition principle our world can happily do its thing unperturbed by other parts of the wavefunction - other “ripples,” or worlds. And while it may seem like it would be physically impossible to have any connection between worlds, it may turn out to be entirely possible to communicate between them.

It expresses the fundamental limit on the knowability of our universe. We’ve discussed it in our early videos on quantum mechanics, but it’s time we looked a little deeper. See, the apparent weirdness of the uncertainty principle hints at the even weirder underlying reality that gives rise to it. The universe we experience seems to be constructed of singular particles with well-defined properties. But this intuitive, mechanical reality is emergent from underlying reality in which the particles that form matter arise from of the combination of an infinity of possible properties. And forget matter - the vacuum itself is the sum of infinite possible particles. If we fully unravel this idea we’ll be on the verge of tackling things like Hawking radiation. But as you’ll see today, in that unraveling we are led, unavoidably, to Heisenberg’s uncertainty principle.Hosted by Matt O'DowdWritten by Graeme Gossel and Matt O'DowdProduced by Rusty WardGraphics by Kurt RossAssistant Editing and Sound Design by Mike PetrowMade by Kornhaber Brown (www.kornhaberbrown.com)Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasWilliam James SidisQuasarTambe BarsbayMayank M.
