00:00Hold on to your hats, folks, because we're about to embark on an incredible journey.
00:04With the help of super smart scientists and their studies,
00:07we've asked AI to take us back a mind-blowing 2 billion years in time
00:11and show us what our awesome Earth looked like.
00:14So buckle up and let's find out.
00:16Once upon a time, way back when Earth was just a baby,
00:19around 4.5 billion years ago,
00:22hopping into a time machine and paying a visit would have been a big mistake.
00:25The whole place was a hot mess.
00:27First of all, the ground was still all gooey and molten,
00:30so landing your time machine would have been a major risk.
00:33Now as soon as you tried to get out,
00:35you would see a completely different Earth compared to what we know today.
00:39The landscape is a patchwork of rugged mountains,
00:42sparkling seas, and vast stretches of land.
00:45Picture massive volcanoes erupting in fiery bursts,
00:49shooting gases and ash into the air.
00:51It's like a crazy fireworks show.
00:53And even if you had a fancy new machine that could hover
00:56and had special shields to handle the heat,
00:58you'd still have a hard time breathing.
01:01You see, the early Earth's atmosphere is a bit moody.
01:04Thick clouds hang in the sky,
01:06casting mysterious shadows on the land below.
01:09The air is as thin as a whisper,
01:11and filled with all sorts of interesting gases,
01:13like hydrogen and helium.
01:15Carbon dioxide swirls around,
01:17giving everything a vibrant green hue.
01:20Water vapor drifts through the air,
01:21creating a sense of humidity and a refreshing mist.
01:24Oh, and there might be a hint of ammonia and methane just to keep things interesting.
01:29Lots of cool gases, huh?
01:30But wait, there's something missing.
01:33Oxygen.
01:33So if you take a deep breath,
01:35you won't feel that familiar rush of air filling your lungs.
01:38On land, there are no lush forests or towering trees just yet.
01:42Instead, you find rugged, rocky terrains.
01:45Some of these ancient rocks bear the marks of intense forces,
01:48collisions and earthquakes that have shaped the land over millions of years.
01:52But amidst all this ancient beauty,
01:55something amazing is about to happen.
01:58Life, in its early stages,
02:00is evolving and preparing for its grand entrance.
02:04Simple organisms, like algae and bacteria, rule the scene.
02:08They thrive in the oceans,
02:10using the abundant carbon dioxide to grow and multiply.
02:13The waters are teeming with activity,
02:16with colorful, microscopic lifeforms buzzing around like a busy city.
02:21These tiny organisms are working hard,
02:23releasing oxygen as they go about their business.
02:26They're like little factories,
02:28slowly changing the composition of the atmosphere.
02:31So this is what the early Earth looked like, more or less.
02:34But why was it so nasty?
02:36And how could it have changed so much since then?
02:39You see, Earth's heat came from all sorts of crazy things
02:43happening during its formation.
02:45First off, there was some serious heat already packed into the objects
02:49that came together to make our planet.
02:51Then, as Earth grew bigger and stronger,
02:53its gravitational force got a major power boost.
02:56It pulled in more stuff,
02:58but it also gave Earth a massive bear hug,
03:00squeezing everything tightly.
03:02And you know what happens when things get squeezed?
03:04They heat up like a pressure cooker.
03:05This crazy heating had a huge impact on Earth's structure.
03:10Picture Earth as a mixed-up bag of rocks, metals, and minerals.
03:13But as things heated up,
03:15the rocks and metals got so toasty that they melted.
03:18And guess what?
03:20The denser metal sank to the center and became Earth's core,
03:23while the lighter rocky stuff floated up to become the crust and mantle.
03:27It was like Earth decided to unmix itself, creating separate layers.
03:31Scientists call this wild separation differentiation.
03:35But the heating didn't stop there.
03:37With all this mixing and moving around,
03:40Earth got even hotter.
03:41It was like turning up the heat in a giant planetary oven.
03:44All this crazy heat had some serious consequences.
03:48Earth's high temperature made everything super speedy.
03:50Tectonic plates were dancing like there was no tomorrow,
03:53making the surface super active and full of geological shenanigans.
03:57Oh, and that's not all.
03:58Earth also got showered by some serious cosmic visitors.
04:02Imagine this.
04:03While Earth was busy gathering up all sorts of space debris during its formation,
04:08the rest of the solar system was causing some major chaos.
04:11Saturn and Jupiter decided to shake things up by changing their orbits,
04:15sending a whole bunch of massive objects hurtling towards poor Earth.
04:18These collisions were no joke.
04:20They packed a punch that melted minerals in Earth's crust and even vaporized them.
04:25These booms were so intense that they even blew gases right out of Earth's atmosphere.
04:30Talk about a wild fireworks show.
04:32Believe it or not, we can still spot ancient battle scars from these collisions.
04:35It takes some careful detective work, but we can catch a glimpse of their aftermath.
04:41For example, there's this place called the Manitsok Crater in Greenland.
04:45Even though there's no actual crater to see,
04:48we can examine rocks that were chilling 12.5 to 15.5 miles below Earth's surface back in the day.
04:54And guess what?
04:56They bear the marks of intense and sudden shock.
05:00Now that's some tough neighborhood.
05:02The wildest collision of them all was with a planet called Theia.
05:06Theia, about the size of Mars, crashed into Earth with a mighty BAM!
05:10It was a colossal event that changed everything.
05:13Theia's metal core fused with Earth's core,
05:16while the outer layers of both planets got shattered and tossed into space.
05:19The result?
05:21A beautiful ring of debris encircling Earth.
05:24Now here's the coolest part.
05:26That debris didn't just float around forever.
05:29It started to come together, like puzzle pieces finding their match.
05:33And voila!
05:34We got our very own moon!
05:37Can you believe it?
05:38And this incredible moon-making process might have taken as little as 10 years or even less.
05:44Crazy, isn't it?
05:46Scientists call this whole moon-forming extravaganza the Giant Impact Hypothesis.
05:51So next time you gaze at the moon in the night sky,
05:54remember that it's actually a huge chunk of our own planet.
05:57And by the way, Earth also had quite the adventure trying to create its atmosphere.
06:02In the beginning, our planet's first attempt at an atmosphere didn't go so well.
06:07It had a thin layer of hydrogen and helium that came along with all the stuff it gathered.
06:11But those gases were like sneaky escape artists and decided to float away into space.
06:18Bye-bye gases!
06:20Luckily, Earth didn't give up.
06:22It went for a second round and this time it was much more successful.
06:26Volcanic eruptions came to the rescue.
06:28They spewed out all kinds of gases like water vapor, carbon dioxide, and a whole bunch of other funky ones.
06:35But even meteorites and comets joined the party, bringing lots of water and nitrogen to the mix.
06:41Earth's atmosphere was becoming quite the party.
06:44But here's the funny thing.
06:45There was no oxygen to be found during this second experiment.
06:49Nope.
06:50Not a single breath of it.
06:51The oxygen that was produced by the sun's rays splitting water molecules
06:55got gobbled up by chemical reactions faster than you can say oxybummer.
07:00It wasn't until Earth's third experiment came along, life, that things started to change.
07:07Photosynthetic organisms took center stage and used all that carbon dioxide in the air to make their food.
07:12And guess what?
07:13They released oxygen as a sidekick.
07:16Eventually, the organisms started belting out so much oxygen that it overwhelmed the reactions
07:21and it began to fill up the atmosphere.
07:23It took a while, though, and it wasn't until about 350 million years ago that we got the oxygen levels
07:29we have today.
07:30About 21% of the air we breathe.
07:32So, from fiery volcanoes to mysterious oceans, this glimpse into the past reveals an Earth vastly different from the one
07:40we know today.
07:42It's fascinating to explore the ancient landscapes and imagine the early stages of life taking shape.
07:47Thanks to AI, we can catch a glimpse of Earth's remarkable history and appreciate the wonders of our ever-changing
07:54planet.
07:55AI art? Sure. Why not?
07:58Artificial intelligence is like a computer brain that can learn and make decisions on its own.
08:02Well, some clever artists have figured out a way to use AI to make art.
08:07They feed the computer a bunch of data like images or sounds
08:10and then the computer uses that data to create something new and unique.
08:14Some people might argue that AI art isn't really art because the computer is doing all the work.
08:21Others believe that while the computer might be doing the heavy lifting,
08:25it's the artist who decides what data to use and how to manipulate it.
08:29Plus, the end result is still a beautiful piece of art.
08:34One of the coolest things about AI art is that it can create stuff that humans might never think of.
08:39For example, one AI program takes an image and analyzes it, looking for patterns and shapes.
08:47Then it enhances those patterns and shapes to create something exaggerated and surreal.
08:52Another type of AI art is called generative art.
08:56This is where the computer creates art in real time,
09:00constantly changing and evolving based on different inputs.
09:05It's like the art is alive.
09:08Some examples of generative art include an app that you can download on your phone.
09:13You can use it to create your own unique designs by moving your phone around.
09:18Such apps use the phone's sensors to generate different patterns and colors based on your movements.
09:23But it's not just abstract art that AI can create.
09:27It can also be used to create more traditional art forms like paintings and sculptures.
09:32For example, an artist used AI to create a digital painting based on brain scans.
09:38The computer analyzed the brain scans and used the data to create a colorful and abstract painting.
09:45It's like a visualization of what's going on inside our heads.
09:49And then there's the famous AI artist named Aida.
09:53She got her name after the famous English mathematician and writer Ada Lovelace.
09:58Aida is actually a robot artist that was created by a team of engineers and artists.
10:03She has a camera in her eye that allows her to see the world around her,
10:07and an arm that she can use to draw with.
10:10Aida has created some amazing portraits and abstract pieces,
10:14and she even had her own exhibition at the University of Oxford.
10:19Now, I know some people might be worried that AI art will replace human artists,
10:23but I don't think that's possible.
10:26After all, art is about more than just creating something pretty.
10:29It's about expressing ourselves and our emotions.
10:33And I don't think a computer could ever truly understand what it means to be human.
10:37Instead, AI art is just another tool that artists can use to create something amazing.
10:43It's like having a new paintbrush, or a new color to work with.
10:46And who knows?
10:48Maybe one day we'll be able to collaborate with AI to create even more incredible works of art.
10:53As it turns out, AI has some problems depicting particular parts of the human body.
10:59Spoiler alert!
11:01AI can't draw human hands or feet properly.
11:04It's kind of like when you were a kid and drew stick figures because hands were too hard to get
11:09right.
11:11If you ask any AI artists what they find most challenging to create,
11:15they'll always say the same thing.
11:18And it's not just the technical constraints.
11:20Human error is also part of the problem.
11:24So, what's the deal with AI and hands?
11:27Well, hands are complex.
11:29They have a variety of different sized and shaped fingers,
11:32each with many joints that must be captured accurately for a hand to look natural.
11:37And did you know that the shape of a person's hand may serve as a more reliable biometric identification than
11:44their facial features?
11:45Even human artists struggle to create convincing hands.
11:49Another factor contributing to the unnatural appearance of AI hands is how humans perceive them.
11:56We have a natural, innate understanding of something about hands that we find highly interesting.
12:01Because of this, if there is an error, we will know about it immediately.
12:05Our expectations of machine learning are sometimes unrealistic.
12:09AI is not the Superman of the art world.
12:12It's a relatively new area.
12:15And we've been trying to perfect the art of sketching hands for thousands of years.
12:19And we still haven't quite made it.
12:23Same goes with creating images with human eyes.
12:26We're so used to seeing human eyes that it's really easy to tell when something is off.
12:33Especially when it comes to proportions.
12:35But fear not, aspiring AI artists.
12:38There are some strategies to help AI art generators produce better outcomes, despite the complexity of hands.
12:45You need to know what AI can and can't do, so you can adjust the suggestions accordingly.
12:52For instance, one could try hiding the hands or having them be behind the characters' backs.
12:58Or even invisible, for that matter.
13:00Sky's the limit.
13:02One could say characters with busy hands make for better artworks.
13:06So maybe create a scenario where the character is holding a cup of coffee or something.
13:11And never underestimate the importance of cropping.
13:15Drawing hands and all might be the lesser of the AI-generated content problems.
13:21One national copyright office has said that pictures created by artificial intelligence
13:25can't be protected by copyright laws because they're not made by humans.
13:30This decision was made when officials looked at the copyright of a graphic novel.
13:35The original copyright was given to the author.
13:38But it was later discovered that some of the images in the book were made using AI software.
13:44The office then took back the original copyright and issued a new one that only covers the writing
13:49and how the images are arranged on the page, not the images themselves.
13:54So what does this mean?
13:56It means that AI-generated content like stories, screenplays, and articles can't be copyrighted in some countries.
14:05But the good news is that human artists can still copyright their images, which might make them more valuable.
14:12Some people think this decision is great because it protects human creativity.
14:17While others think it's bad news for AI-generated content creators
14:22who believe that they come up with the ideas and prompts that the AI uses to create the images.
14:27The copyright office officials backed up their claims by saying
14:31that the process of making images using AI is not the same as that of a human artist, writer, or
14:38photographer.
14:40The AI software used to create the images in the novel generates four different images
14:45based on its training data when given an initial prompt by a user.
14:50The user can influence subsequent images with additional prompts,
14:53but the process is not controlled by the user because it's impossible to predict what the software will create.
15:00In the future, the same copyright office will still register works that contain unprotectable material
15:07that has been edited or revised by a human author.
15:10So, if an artist has creative control over an AI image-generating tool, the output may be protectable.
15:17To make things clearer in the future, we may need to define what product of human authorship actually means.
15:23In reality, only time will tell whether such decisions are good for artists or not.
15:30Not all AI-generated images are made in good faith.
15:34Some pictures found online can trick you into believing the most outrageous of things.
15:41So, what can you do to spot some of these images and distinguish between reality and fiction?
15:46First, make sure to look carefully at the picture.
15:50Zoom in and examine the details.
15:53Next, try to find the image source.
15:55This can be done by reading comments or doing a reverse image search.
16:00Next, pay attention to body proportions as well.
16:04AI-generated images can have discrepancies,
16:07such as unusually long fingers or disproportionate body parts.
16:11Keep an eye out for typical AI errors,
16:14like extra fingers or deformed glasses frames.
16:17If the image looks too perfect and artificial, it may be a fake.
16:22AI tools often create ideal images that are flawless,
16:25with perfect skin and hair.
16:27Real life is not always so perfect.
16:29Finally, examine the background.
16:31Cloned objects or blurred backgrounds can be a sign that the image was manipulated.
