What is the Higgs field and why is it a fundamental part of our universe? Tweet at us! @pbsspacetime Facebook: facebook.com/pbsspacetime Email us! pbsspacetime [at] gmail [dot] com Comment on Reddit: http://www.reddit.com/r/pbsspacetime Quantum Field Theory is generally accepted as an accurate description of the subatomic universe. However until recently this theory had one giant hole in it. The particles it describes had no mass! The Higgs field and the Higgs mechanism were proposed long ago in order to give particles mass, but it was only in 2012 that the existence of the field was proved with the discovery of the Higgs boson by the Large Hadron Collider. In this episode of Space Time, we tell you exactly how the Higgs field can "give" something mass, which opens the door to a deeper understanding of what mass really is. ______________________ Comments: AFastidiousCuber https://www.youtube.com/watch?v=xx4562gesw0&lc;=z12gxfljuqeqybnvb22pijcjhympx3hyc04 Casteverus https://www.youtube.com/watch?v=xx4562gesw0&lc;=z13jhbdifmvvgtds122igdapnqjqe1vt4 Gareth Dean https://www.youtube.com/watch?v=xx4562gesw0&lc;=z12qfluaqqn1cbswj04chx1bhrjygnzoif0 WR3ND https://www.youtube.com/watchv=xx4562gesw0&lc;=z12xxhwzbpqgcpv2v221whw54p3ef5zs1 ______________________ Further Reading and Watching: Leonard Susskind on the Higgs interaction: https://www.youtube.com/watch?v=JqNg819PiZY Gravitational waves heating up a star: McKernan et al. 2014 http://arxiv.org/abs/1405.1414

Let’s build a black hole! Tweet at us! @pbsspacetime Facebook: facebook.com/pbsspacetime Email us! pbsspacetime [at] gmail [dot] com Comment on Reddit: http://www.reddit.com/r/pbsspacetime Black holes have mystified physicists for decades, but with the help of quantum mechanics, we are beginning to make serious progress in understanding these strange objects. This week on Space Time, Matt dives deeper into the physical process of creating a black hole, and what that can tell us about how black holes behave. For a primer/refresher, be sure to check out our previous video on Black Holes: https://youtu.be/vNaEBbFbvcY Also, check out our friends over at The Good Stuff.

The Universe is all of spacetime and everything that exists therein, including all planets, stars, galaxies, the contents of intergalactic space, the smallest subatomic particles, and all matter and energy.[1][2][3][4][5][6] Similar terms include the cosmos, the world, reality, and nature. The estimated diameter of the observable universe is about 93 billion light years or 28 billion parsecs.[7] Scientific observation of the Universe has led to inferences of its earlier stages, which appear to have been governed by the same physical laws and constants throughout most of its extent and history. The Big Bang theory is the prevailing cosmological model that describes the early development of the Universe, which is estimated to have begun 13.798 ± 0.037 billion years ago.[8][9] Scientists remain unsure about what, if anything, preceded the Big Bang. Many refuse to speculate, doubting that any information from any such prior state could ever be accessible.[citation needed] There are various multiverse hypotheses, in which some physicists have suggested that the Universe might be one among many, or even an infinite number, of universes that likewise exist.[10][11] The universe is composed of 4.9 percent atomic matter, 26.6 percent dark matter and 68.5 percent dark energy[12] Observations of supernovae have shown that the Universe is expanding at an accelerating rate.[13] There are several competing theories about the ultimate fate of the universe.

Which means that there would be an actual edge of the Universe. What happens at that edge? Is there a restaurant? Join Matt on this week’s episode of Space Time as he explores the greatest expanses of our Universe. So what do you find when you reach the edge? More Universe? Bubble Universes?

--- ABDH Media - Space --- In physics, spacetime (also space–time, space time or space–time continuum) is any mathematical model that combines space and time into a single interwoven continuum. The spacetime of our universe is usually interpreted from a Euclidean space perspective, which regards space as consisting of three dimensions, and time as consisting of one dimension, the "fourth dimension". By combining space and time into a single manifold called Minkowski space, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels. *Subscribe for more Educative & Space Documentaries (Like & Share) * Visit our website: http://www.advexon.com * ABDH Media Documentaries: https://www.youtube.com/channel/UCHx69kZbXbX6WgMq_njRvFA *NOVA | PBS Documentaries (HD): https://www.youtube.com/channel/UCYMWnCecPvpQJj8sBPUi4bA #ABDH #space #spacedocumentary #AlienPlanets #NEWFullScienceDocumentaries #SpaceDocumentary2015 #alien #spacedocumentarynationalgeographic #spacedocumentaryhd #spacedocumentarybbc #spacedocumentary2015hd #spacedocumentaryplaylist #spacedocumentarynationalgeographic2015 #spacedocumentaryblackholes #spacedocumentaryforkids #spacedocumentaryalienplanets #spacedocumentaryasteroidthedoomsdayrock #spacedocumentary2015aliens #aspaceodysseydocumentary #spacedocumentaryblackholesfdc #spacedocumentarybriancox #spacedocumentarybest #spacedocumentarybbc2015 #spacedocumentaryblacksky #spacedocumentarybigbang #bestspacedocumentary2015 #spacedocumentarycosmos #spacedocumentaryconspiracy #spacedocumentarychannel #spacedocumentarychildren #discoverychanneldocumentaryspace #spacecolonizationdocumentary #spaceshuttlechallengerdocumentary #spacetimecontinuumdocumentary #historychanneldocumentaryspace #spacedocumentarydiscoverychannel #spacedocumentarydarkmatter #spacedocumentarydiscovery #deepspacedocumentary #deepspacedocumentary2015 #spacedisastersdocumentary #spacedivedocumentary #spaceshuttledisasterdocumentary #davidattenboroughspacedocumentary #spaceelevatordocumentary #spaceexplorationdocumentary2015 #earthfromspacedocumentary #spaceexplorationdocumentary2015 #spaceengineeringdocumentary #edgeofspacedocumentary #emptyspacedocumentary #spacedocumentaryforchildren #spacedocumentaryfilms #spacedocumentaryfull #spacedocumentaryfulllength #spacedocumentaryfuture #spacedocumentaryfunny #2015spacedocumentaryfull #spacedocumentarygalaxies #spacedocumentarygravity #spaceuniversegalaxydocumentary #spacedocumentarynationalgeographic2015 #spacetraveldocumentarynationalgeographic #spacedocumentarynationalgeographichd #spacedocumentaryhd2015 #spacedocumentaryhd1080p #spacedocumentaryinhd

We have begun to track projectiles large enough to destroy our planet, and we are in the clear for the foreseeable future. However, there are countless asteroids large enough to take out an entire city that we cannot see. Matthew O'Dowd goes over our defensive options in this week's episode of Space Time!
