The history of the universe explained in 4 minutes | BBC Ideas


Our Universe was created about 13.8
billion years ago in the Big Bang. At first, it was very simple, consisting of little more
than hydrogen and helium and lots of energy. There were no stars or galaxies, no planets
and certainly no living creatures. Then, gradually,
more complex things appeared. The first stars and galaxies probably appeared within about
200 million years of the Big Bang. As big stars lived and died, they
blew up and created new elements. Those new elements allowed
the creation of new materials such as the dust
and ice and rocks and minerals from which planets are made. Our Sun and solar system appeared
about 4.5 billion years ago, and by 4 billion years ago, it’s likely that life
had emerged on Earth. Life evolved and diversified but most of it consisted of tiny,
single-celled organisms until, about 1 billion years ago, the
first many-celled organisms appeared. From about five hundred
million years ago, big creatures became
much more common, from trilobites to trees
to tyrannosaurus rex. The first humans
evolved very recently, just about 200,000 years ago. Though it wasn’t obvious at the time, the appearance of humans
turned out to be hugely important because humans were able
to share ideas and information better than any other species
that ever existed. Using that ability, our ancestors gradually
built up stores of information that allowed them
to control their environments more and more powerfully. The process accelerated until,
in just the last 100 years, we have become so powerful that
what we do in the next few decades will determine the future
of the oceans, the climate, and of most
other species on Earth, including our own descendants. Many scholars believe that this
represents a new geological epoch. The Anthropocene. In the last 50 years, we humans have begun to control
energy and resources on such a vast scale
that we are transforming the land, the seas and the atmosphere
of the Earth. So, planet Earth is at a turning
point in its history. Humans, now the dominant species, will either lead the biosphere
towards a flourishing future, or to catastrophe. Perhaps triggered by nuclear wars that could ruin swathes
of the planet in just a few hours, or caused more slowly by the
continued release of greenhouse gases until the land is flooded and global climates
are too hot to grow enough food. Never before has a single species determined the future
of the entire biosphere. The good news is that we
understand the science, and we already have
many of the technologies needed to build a sustainable future. What’s missing now
is the political technology. How can governments and peoples be encouraged to see the challenges
that they all share, rather than simply defending their
own local and immediate interests? Only by collaboration can we avoid
the many dangers we face today. Can we steer planet Earth towards
a prosperous future in which humans and all the other organisms on which
we depend can flourish for thousands, even perhaps, for millions
of years into the future?

  1. The responsibility lays on the head of top 10 richest countries that are contributing most to the greenhouse effect. They should not be greedy and selfish. They should look at the long term effects not the short term gains

  2. AI IS THE ANSWER AT THE END..

    If you look at the growing pattern.
    Technology is becoming more like human but can go on indefinitely,, BUT ONLY ALONG SIDE HUMANS TO DO THE REALLY FIDDLY BITS MACHINES CANNOT DO.. Like nuts and bolts in the correct places.. AND TO KEEP POWER PLANTS ALIVE TO KEEP AI RUNNING..

  3. Collaboration ? Yes. More importantly, reparations, by the developed nations, for all the exploitation that led their nations' development. It's inconvenient to think that your development was based more on exploitation than anything else, I understand, but there is too much evidence to ignore.
    Let's collaborate to tackle climate change, but also contribute in proportion to how much we have taken, from our own land and that of others. Only then can we hope to bring a change.

  4. Bill wurtz beat you to the mark I’m afraid, but this was sufficiently entertaining and educational, cool video

  5. This is bullshit and nobody knows anything until you die and even then might not get all the answers WE DONT KNOW SHIT AND PROBABLY BEVER WILL END OF STORY

  6. What are stars made of? Stars are bodies of water or fluid, think about why stars are bright and produce light. this comes from vibration, light can only be emitted when there is movement aka vibration. Water is best representation of vibration on this planet but all things are fluid. What they call dark matter or ether, think of that like the overall fluid or body of water we are in and then stars are like bubbles within that water that are vibrating and rotating desperately from the ether and after constant vibration light begins to be generated. but all bubbles will burst eventually….

  7. How were ghosts created ? and how do they react to what I say.. I used to work at a haunted school and I said it wouldn’t slam a door.. 5 minutes it did.. what is that made of?

  8. This is the worst fairytale ever told … Evolution.
    Nothing exploded and created everything …. yeah that makes total sense … not!

  9. Just the regular misrepresentation of science and history by the usual propagandists of the Islamo-Nazi-Democrap Party's "Education and Editorial Department". Politcal dogma and fairytales are not science.

  10. LIES LIES LIES. WE HAVE ALL BEEN LIED TO OUR WHOLE LIVES! SO OUR BELIEFS lead us to their slavery trap.

    And that’s why then don’t teach you about money in school.

    Think about that

  11. Best thing for this planet would be to drastically reduce the amount of humans and get rid of religions that divide us all where man cannot think collectively, for the good of the planet and species

  12. According to Atheists and Evolutionists, a day would be 23 hours in the time of the dinosaurs, 66 Million Years Ago, (I got that from the Nasa website, check it out by yourself if you don't believe me) So that means were loosing about an hour every 66 Million years. Now : 4 540 000 000/66 000 000 = 68.7878787879 and 24-68 = -44.
    The Earth is about 6 thousand years old, Turn your Eyes upon Jesus.

  13. I would rather dedicate my time protecting the earth rather than focus on negativity of why the need to leave it, searching on planet to go and how to go there. If ur worried about nuclear then why are humans making it in the first place? My theory is they scare people about doomsday scenario of earth so they can convince people to join their plan to fund it bec obviously funding is delaying their plan. I hope that human should unite to fight and stop this people to their plan of scaring us people here. And focus their energy om how to make the earth better. Because anywhere u go, asteroids can also go there and worst is their dream planet will their burial site only

  14. While this was an interesting video, the title is misleading: Only a small part of this video is about the history of the universe and the rest is about Earth.
