7 stunning end of the world predictions

According to scientists, the world could endon March 16, 2880. Asteroid 1950 DA has a 0.3% chance of hittingEarth in 867 years. At 1 km in diameter, rotates once every twohours and six minutes and would cause untold damage were it to hit the earth.The Shrinking Mt Everest, 2015 There was something else going on with thelandscape of Nepal, which nobody would have even thought of us.As the earthquake subsided, what came as a real shocker was that the earth's highestmountain range, Mt. Everest stood 2.8 cm smaller, according to satellite data.Earth's magnetic field flips!

The biggest reason which led the Mayan apocalypsebelievers to predict the end of the world in 2012 was based on the changing patternsof Earth's magnetic fields. However, Earth's magnetic field is stillweakening 10 times faster than normal, at present and can further weaken.Earth's magnetic field flips!

by 2021.A series of apocalyptic events, including floods and earthquakes will spell the endof the world before 2021, according to a doomsday prophecy.NEW UNKNOWN WEAPON In this scenario a new type of weapon is created.It might be a Fusion Bomb capable of turning the world into a shortterm star, it mightbe a new form of radiation or it might even be a gravitational weapon that stops the worldspinning. TOTAL NUCLEAR WARThe devastation from thermonuclear blasts would be bad enough and would send what wasleft of mankind back to the Stone Age.

The radiation would engulf the planet on ascale that can't be imagined. Within 6 months anyone who was not “blown up� would bevery sick. Within 24 months just about everyone is dead.

Civilizations at the End of Time Black Hole Farming

Today's topic, Black hole Farming, is goingto be a difficult one because it's a tutorial I probably shouldn't have made without coveringother topics first, and also because it draws heavily on quite a few other tutorials I didmake first. So it essentially amounts to three topics that we need to cover today and assumesa knowledge of the most recent tutorials on the channel, which means that if this is yourfirst visit to this channel, while I normally try to make tutorials as standalone as possibleand you probably can watch this without watching the others first, it isn't advised.That said, it isn't absolutely necessary and to help with that, whenever I bring uptopics we've covered in more detail in other

tutorials you will usually see an intutorial linkfor that tutorial pop up, and you can just click on it to pause this tutorial and watch that one.You can also turn on the closed caption subtitles if you are having problems understanding me.So I said it was actually three topics, not just one, for today. What are those threetopicsé Well let's list them out. 1) Using Black Holes for Power SourcesWe've talked about this before but mostly in the context of Hawking Radiation from small,artificial black holes. Today's tutorial is focused on large, longlived black holes,where Hawking Radiation is incredibly tiny and other methods are needed. So we'll bediscussing those other methods as well as

what the implications of living on minimalHawking Radiation would be like 2) The Fate of the UniverseIn this section we'll go over the timeline of ages of the Universe fairly quickly, andalso quickly cover some of the other ideas for Civilizations far in the future, whichwe may expand on in future tutorials. 3) Black Hole FarmingIn the last section we'll get into the meat of things, trying to contemplate what civilizationswould be like that essentially fed themselves off black holes. It's the concept of usingblack holes as the power source for your civilization, and actually creating or placing black holesto make that work best, which is the origin

of the title. I think it summons to mind theimage of farmer in coveralls with a pitchfork literally farming black holes but we'resticking with it anyway. So without further ado, let's dig in.Our first topic, using Black Holes as power sources is, as I mentioned, something we lookedat before in the twin tutorials discussing Hawking Radiation, MicroBlack Holes, and using themto power starships. You may want to watch those, or rewatch those, before proceeding,but the quick summary is that Black Holes are thought to emit Hawking Radiation looselyin proportion to their size. Except backwards from what you'd expect, the giant monstersized ones in the centers of galaxies emit

so little of it you'd need a trillion, trillionyears to collect enough energy to turn on a little LED light for a fraction of a second.Alternatively the small ones gush out power so fast they burn out their tiny mass in veryshort times. There's two upshots of this. First, thatthe lifespan of black holes is proportional to the cube of the mass, one twice as massiveemits only a quarter of the power and lives eight times longer, one ten times as massiveemits a hundredth of the power and lives a thousand times as long, etc.Second, if we can make artificial black holes, and especially if we can feed matter intothem to replace what they lose to Hawking

Radiation, we have an excellent power sourcefor things. Black Holes are roughly on par with antimatter, and vastly better than nuclearfission or fusion, in terms of energy per unitmass of fuel, and they don't blow upunless you starve them to death, a process that would take years or centuries normally,making them a very attractive option for power generation and storage.This is assuming we can figure out how to make small ones and feed them, both of whichare actually a lot harder than with their bigger, naturally occurring kindred. Whichagain emit virtually no energy on timelines that can be measured without using scientificnotation.
