The History and Future of Everything — Time

Time makes sense in small pieces. But when you look at huge
stretches of time, it’s almost impossible to wrap
your head around things. So let’s start small with minutes, hours, days. You probably spent the last 24 hours
mostly sleeping and working, with some coffee in there somewhere. Please watch less TV. Now let’s look at 2013:
relatively unnoticed, Hitler’s bodyguard died at the age of 96 while in June, Edward Snowden
started the NSA scandal. Moving back a bit, the 21st century is
still pretty young and largely shaped by the attacks on 9/11 that ultimately
led to the third Iraq war. Oh, and Facebook and smartphones
took over our lives. But we’re just getting started: Let’s back up further! The 20th century has seen its share
of conflicts too. After two devastating World Wars, the Cold War lasted for almost the
whole second half of it. An average human lifespan
covers most of this stuff as well as the birth of the internet
and the beginning of the information age. The oldest living person on Earth
is currently Misao Okawa, who was born in 1898, which means that
her birth was closer to Napoleon ruling Europe
than to the current day. The last 500 years of human history brought enormous changes
to our lifestyles: Industrialisation gave rise to new
ideas like communism, farmers became workers
and knowledge became easier to distribute. The theory of evolution changed how we
saw ourselves and the world we live in. All in a few hundred years! The 15th century was very eventful: Columbus’s “discovery” of America
and the fall of Constantinople mark the end of the Middle Ages. People in the Middle Ages where super into
war over territory and religion but the Black Plague was far
more efficient than war, killing every third European in six years. Arriving in the Common Era,
let’s take a look where we came from! Our current century is tiny,
and 2013 is barely visible. This is recorded human history. The pyramids were constructed
4,500 years ago, the peak of the Roman Empire was
2,000 years ago, so to the Romans the pyramids were as old
as the Romans are to us today. History starts with writing.
But what happened before that? About 12,000 years ago,
the agricultural revolution took place. Mankind began farming,
which gave rise to the existence of cities
and larger communities. The dominance of the human species over
planet Earth really started here. 90,000 years ago, neanderthals and
humans coexist in Europe. Fun fact: this is roughly the time
period a modern spacecraft would need to reach the nearest star. Homo sapiens, the modern human,
evolved 200,000 years ago. Looking at all of human history, what
we call AD seems pretty small, doesn’t it? 6,000,000 years ago, our ancestors and the modern chimpanzee shared
a common ancestor for the last time, and for 2,750,000 years, stone tools
were all the rage. A mere 65,000,000 years ago, the age of
the dinosaurs ended in an enormous explosion, which paved
the way for the rise of mammals. But the dinosaurs ruled the Earth
for an incredibly long time: over 165,000,000 years! That’s so long that it means a T. rex
that lived 65,000,000 years ago is closer to seeing a
live Miley Cirus concert than to seeing a live stegosaurus! Animal life on this planet
started 600,000,000 years ago: the earliest animals were fish and
other small simple sea creatures, then came insects, then reptiles, and finally, around 200,000,000 years ago, mammals join the party! Life itself began much further back: 3,600,000,000 years ago. Before any animals appeared,
there were 2,400,000,000 years when life consisted only of tiny microbes, countless single-cell bacteria. For 3,000,000,000 years, all life on Earth
was invisible to the naked eye. It’s hard to understand how
single-cell organisms could develop into complex
life forms like fish or sloths. The answer is time, a whole lot of time: 2,400,000,000 years is lot of
time to work with! 4,600,000,000 years ago, the Sun was born
from the remnants of a giant explosion, 60,000,000 years later, Earth formed. In those early years, frequent bombardment
by comets and asteroids supplied the Earth with large oceans
and a moon to send spaceships to. But as far as the whole universe goes,
our Solar system is pretty new. 13,750,000,000 years ago, the
universe was born, and 600,000,000 years later, our own galaxy
formed from billions of stars, but what was before the Big Bang? The truth is, we don’t know that yet,
and maybe we never will. But we gave it some colours so
at least we have that. And there you have it: the past. Now let’s take a look at what
we know about the future. In roughly 1,000,000,000 years, the Sun will be so hot that
life on Earth becomes impossible. The death of the Sun 4,000,000,000 years
later marks the end of the Solar system. OK, so no more Solar system. And what happens after that? A few trillions years from now,
star production will cease and one day the last star in the
universe will die. The universe will turn dark, inhabited only by black holes. Long after the last black hole
has evaporated, our universe reaches its
final stage, something called heat death. Nothing changes anymore, the universe is dead forever. Now you’re feeling some pretty
weird feelings right now, aren’t you? We are too. It’s only natural. The good news is: this is all far, far away. The only time that actually
matters is now! That cute girl you like, ask her out! Time is precious, make it count! Subtitles by the community

  1. Finally ty Kurzgesagt for proving that God doesnt exist………Geez now i can stop going to church for no reason

  2. It will be oulled together by its own gravity to 1 point, because it will stop expanding over time. The amount of energy created by that would make it explode again. Just my opinion

  3. So, magma turned to stone then life cam and decomposed so dirt was biulding up. Also this is the 20th centery not the 21st

  4. Columbus din't discover america indians did and if he wasn't there… someone else could have done it okay. So my c
    School discrit doesn't have off on columbus day anymore

  5. TIme is a construct. I believe the broad strokes presented here, but not the accuracy of the time spans presented. We are living in a lie!

  6. Betting 95% of the people who are commenting "asked out a cute girl, she said no" are lying for likes/because they're sadbois. Congrats on entirely missing the point.

  7. Too creepy at the end and I think the real end for the universe is

    Fish takes over gods place

  8. You had me up to, "ask the cute girl out." So next time maybe just say, "go ahead and move people FORWARD today!"

  9. I'n sorry, but I've heard other future of the Universe:
    First, Earth will be getting hotter and hotter, as it is today (attention, everyone – humankind has little influence on it. It will happen sooner or later, whatever we'll do something or not). Because of it, glaciers will melt and the sea level shall rise up. Then, after lots of years, it will freeze in the next ice age, and it will do it over and over again – that's the natural balance, so don't worry about this.
    It will be looping until a one billion years from now. But then our Earth will get totally unsuitable: the temperature will rise up so intensely, that water will start to evaporate and will get locked in the clouds, that will be getting denser and denser, admiting less and less sunlight, until there will be completely dark, but also cloud layer will be making greenhouse effect stronger and stronger, so as longer it is, the faster it will be. The clouds will also start to connect with sulfur, making an acids, that will fall from the sky like a rain, devastating what's left on Earth.
    Water will be also evaporating into steam, making Earth's atmosphere more and more dense. Rising pressure will destroy human's infrastructure and other things as well. Like clouds the steam will also be creating acids, making the atmosphere unable to breathe.
    The process will be pursed until the last water on Earth will evaporate, and there will be no more live on Earth. Now it will be the next Venus, which will also have crushing pressure, unable to have live on and completely dark at surface.
    To don't make disappointed, there is also a romantic part of this future. Because humans won't be flying to the space no more, space junk we've left in orbit will start to get effected by the Earth's gravity. Because our present planet is more like a potato, rather than perfect sphere, it's gravity pulls everything in orbit into the equatorial orbit, so that's what will happen into the space junk, and after a few hundred years, with the help from our Moon, the Earth will get it's own ring system! Unfortunately, it will happen only when we will abandon Earth…

  10. I get it until I realize no physical evidence backs any of the dates up. Or am I to take this in as science cause I don’t understand the math involved? Anyone?

  11. I like kurgeatat videos, but I hate when they leave a theme at the end, like the cute girl thing. Leave it open-ended. It's more interesting that way

  12. Kurzgesagt: We'll never know what things happened before the big bang
    Dr Strange: I KNOW. (pick up the eye of agamotto)

  13. Lmao 90% of these comments are about the "ask her out" line

    Edit: I actually did today lmao, she said "maybe" cuz she didn't know what to say. Not sure how things will turn out.

  14. I think there is no death of our universe. Because in the last time there may be happen any hypothetical event to create another universe.

  15. I love the Indonesian Bahasa subtitle, so fun to read.
    Suka sekali yg buat subtitle Indonesianya. Semangat sekali teksnya

  16. so on top of try to colonizing stars we gona need to find out how to colonizing other dimension… ahem … so does that mean angels and demon are aliens !!!!???

  17. It's awesome how I can't resist the smile when I watch your videos
    A great amount of pleasure and happiness I feel by every second in those reports
    You are by far the most precious scientific channel I have ever seen.

  18. Guys! The universe a cycle repeating itself. When the last black hole gets exhausted. Then the singularity is against achieved. Which will lead to an another Big Bang.

  19. hmm the tick-tocking in the video is pretty synchronized with the seconds going up one at a time


  21. Missao Okawa died age 117, Kurzgesagt. The oldest living person is either 519 or 719 years old arrested in 1876. Use this update.

  22. I dislike this whole 'common era/before common era' schtick. If you want to use the current year numbering scheme you should acknowledge its origin and relatively arbitrary start date. If you want a so-called 'common era' then you should pick a start date which actually has things in common with the present – maybe the beginning of the enlightenment, or the beginning of recorded history, but not an arbitrary date some 2 kyr ago.

  23. İspatlanamamış ve baştan sona yanlışlarla dolu olan tesedüfe tapanların Evrim teorisinin canı cehenneme!

  24. Youtube these past few years….
    2013: no
    2014: nope
    2015: still no
    2016: hello no
    2017: i don't think so
    2018: just a little longer
    2019: GO GO GO!! Recommend it now!

  25. This is giving me its a blessing but also a curse vibe at the future part cuz good things always have a bad side like plastic
