But every rule has an exception and this rule is no exception because: It’s never aliens, until it is. So is it aliens yet? And on today’s Space Time we’re going to examine all the best case scenarios for life beyond Earth. If you want more alien content, check out the ALIENS!

There are cosmic events so powerful that they leave permanent marks on the fabric of the universe itself. Imagine two colossal black holes spiraling into each other, yes they send ripples in the fabric of spacetime—gravitational waves that we’ve only recently learned to sense. Ripples pass, leaving the pond … or the universe … unchanged when they’re gone. But ripples aren’t the only type of wave. There’s another type of wave that leaves a permanent mark—a memory etched in the fabric of the universe. They’re akin to gravitational tsunamis, and we’re on the verge of being able to detect them.

To support your local station, go to: http://to.pbs.org/DonateSPACEHow do you take a picture of a black hole and what can we learn from it? Our first ever actual bona fide photo of a black hole, made by the Event Horizon Telescope and revealed to the world in a press conference on April 10th. Since then it’s got plenty of coverage, because … I mean look at it. It’s a freaking black hole. It’s black, it’s holey, it’s everything we hoped it would be. Now that the giddiness has subsided and I personally have stopped spending hours on end staring at a black spot, we can take a breath and actually look at the real science here and discuss exactly how a picture like this could be taken and what we can learn from it.Check out the new Space Time Merch Store!https://pbsspacetime.com/Support Space Time on Patreonhttps://www.patreon.com/pbsspacetimeNeed a Black Hole Refresherhttps://youtu.be/vNaEBbFbvcY#Blackhole #astrophysics #spacetimeHosted by Matt O'DowdWritten by Matt O'DowdGraphics by Murilo Ceasar LopesDirected by Andrew KornhaberProduced By: Kornhaber BrownSo, how do you take a picture of a black hole? The beast in question is the supermassive black hole in the center of this – the M87 elliptical galaxy. It has an estimated mass of several billion times that of the Sun, which gives it an event horizon larger than the solar system. M87 is 53 million light years away, so resolving that black hole is equivalent to resolving a grain of stand on the beach in LA – if you’re standing in New York. By comparison, the Hubble Space Telescope would struggle to see a large watermelon over that distance.Big Bang:Anton LifshitsDavid NicklasFabrice EapJuan BenetQuasar:Mark RosenthalTambe BarsbayVinnie FalcoHypernova: Antoine BruguierChuck zegarDanton SpiveyDonal BotkinEdmund FokschanerHank SJohn HofmannJordan YoungJoseph SalomonekkmMark HeisingMatthewMatthew O'ConnorThanks to our Patreon Gamma Ray Burst Supporters: Adrien MoyneuxAlexander LazerevAlexey EromenkoAndreas NautschAntonio RuizBradley JenkinsBrandon LabonteBuruk AregawiCarlo MogaveroDaniel LyonsDavid BehtalaDustan JonesGeoffrey ShortJames FlowersJames QuinteroJohn FunaiJohn PollockJonahJoseph DillmanJoseph EmisonJosh ThomasKevin WarneKyle HoferMalte UblMark VasileNathan HitchingsNick VirtuePaul RoseRatfeastRyan JonesScott GossettSigurd Ruud FrivikTim StephaniTommy MogensenYurii Konovaliukسلطان الخليفي Learn more about your ad choices.

Remove your personal information from the web at https://joindeleteme.com/SPACETIME Big things are made of smaller things, and those smaller things are made of smaller things still. That’s reductionism in a nutshell, and digging our way to the smallest layer has been one of the primary goals of physics for ever. But what if, just before we reach the bottom, we find out that reductionism fails?
