In fact, probably the Big Bang is nothing like what you were taught.A hundred years ago we discovered the beginning of the universe. Observations of the retreating galaxies by Edwin Hubble and Vesto Slipher, combined with Einstein’s then-brand-new general theory of relativity, revealed that our universe is expanding. And if we reverse that expansion far enough – mathematically, purely according to Einstein’s equations, it seems inevitable that all space and mass and energy should once have been compacted into an infinitesimally small point – a singularity. It’s often said that the universe started with this singularity, and the Big Bang is thought of as the explosive expansion that followed. And before the Big Bang singularity? Well, they say there was no “before”, because time and space simply didn’t exist. If you think you’ve managed to get your head around that bizarre notion then I have bad news. That picture is wrong. At least, according to pretty much every serious physicist who studies the subject. The good news is that the truth is way cooler, at least as far as we understand it.Check out the new Space Time Merch Store!https://pbsspacetime.com/Support Space Time on Patreonhttps://www.patreon.com/pbsspacetimeHosted by Matt O'DowdWritten by Matt O'DowdGraphics by Leonardo ScholzerDirected by Andrew KornhaberProduced By: Kornhaber BrownBig Bang Supporters:Anton LifshitsDavid NicklasFabrice EapJuan BenetJustin LloydMorgan HoughQuasar Supporters:Mark HeisingMark RosenthalTambe BarsbayVinnie FalcoHypernova Supporters:Chuck ZegarDanton SpiveyDonal BotkinEdmund FokschanerHank SJohn HofmannJohn R.

Boosters, dead satellites, and sometimes even old space stations get dropped out of the sky fairly often. While the litter seems a little inconsiderate, this is probably far safer than the alternative. The accumulation of space junk poses a huge risk to all human operations in space especially if we cross the threshold into the chain reaction of exponentially growing collisions known as the Kessler Syndrome.

Or gods and heroes looking down from their constellations? Or lights kindled above middle earth by Varda Elbereth and brightened with the dew of the trees of Valinor? Science has long pondered the mysteries of the stars. This is how we finally figured them out.Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetimeCheck out the Space Time Merch Storehttps://pbsspacetime.com/Sign up for the mailing list to get episode notifications and hear special announcements!https://mailchi.mp/1a6eb8f2717d/spacetimeHosted by Matt O'DowdWritten by Matt O'DowdGraphics by Leonardo Scholzer, Yago Ballarini, and Pedro OsinskiDirected by: Andrew KornhaberCamera Operator: Setare GholipourExecutive Producers: Eric Brown and Andrew KornhaberEnd Credits Music by J.R.S.

For example Max Planck used a quantization trick to figure out the spectrum of light emitted by hot objects. The quantization part of his math trick was meant to disappear in the final form of equation, but it remained - it proved fundamental. That math hack turned out to represent the very real quantum nature of the photon. This insight let to the discovery of all quantum physics. A more recent mathematical hack is the virtual particle. They started out as a trick to make impossible calculations in quantum field theory possible. Possible, at least, for the sort of people who can do quantum field theory. So will virtual particles also prove to represent a new underlying aspect of reality? We’re going to go pretty deep in this one - but it will bring us to a better understanding of the quantum nature of reality, so stick with me.Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangDavid NicklasCoolAsCatsAnton LifshitsFabrice EapJustin LloydJuan BenetQuasarTambe BarsbayMark RosenthalDean FuquaJames FlowersVinnie FalcoHypernovaChuck ZegarJordan YoungJoseph SalomoneJohn HofmannMartha HuntMatthew O’ConnorRatfeastBrent MullinsDonal BotkinEdmund FokschanerMax LevineThanks 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.
