A Tour of The ENTIRE Universe

Your home planet. 500 years ago, humanity thought this was the center of the universe. And if this video teaches you anything, it's that, oh boy, they were wrong. I'm going to take you on a tour of our entire universe. Starting at Earth, going to the solar system, our stellar neighborhood, the Milky Way galaxy, the local group of galaxies, and all the way to the observable universe. There's something about space that feels unmatched. An unmatched level of emotion, curiosity, scale, it's all so intrinsic to our story, but at the same time, it feels so unbelievably far away from us. This is your entire solar system. It consists of the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, five dwarf planets, over 400 moons, over 1 million asteroids, and billions to trillions of comets. Seriously. Earth is right here, and all the other planets are far away. If we flew 900 kilometers an hour, which is the average speed of a passenger airplane, it would take us 20 years to fly to the sun, 11.5 years to fly to Mercury, 5.2 years to fly to Venus, 10 years to fly to Mars, 80 years to fly to Jupiter. 152 years to fly to Saturn, 345 years to fly to Uranus, 550 years to fly to Neptune, and 745 years to fly to Pluto. The planets are pretty far, huh? Or maybe your planes are just slow. Zone number two, the other solar systems around you. Here are the other closest stars to Earth. We have the Alpha Centauri system which is actually three separate stars, the closest which is Proxima Centauri. We have Barnard's star, we have Wolf 359, and a whole bunch of cosmic neighbors surrounding us. And here's a quick fun fact. If you were to take a passenger airplane to the closest star to us, which is Proxima Centauri, that journey would take you over five million years. Most of the stars you see in the night sky are in this region. And without a telescope or any other way to look deeper into space, we would think this is everything. But as you can already guess, we are nowhere near done our tour of the universe. Let's start at our solar system, which is right here, and zoom out again. This time I turned up the brightness of all the stars in our galaxy, so we can clearly see the stars surrounding us. I want this to put into perspective how many other solar systems are in our galaxy. An incomprehensible number. Not hundreds. Not thousands. Not millions. Not billions. But hundreds of billions of stars. By the way, I make all the music in my videos myself. I release them on Spotify, Apple Music, everywhere. So if you want to support my music, I put the name of the songs on the screen while they are playing. So we are seeing a lot of stars right now, but all of them are just in our small local region of our galaxy. This is just our neighborhood in an entire city. And eventually, as we keep zooming out, you will see our entire galaxy. Okay, so it's hard to make out what we're looking at, and that's because our galaxy is so large that we can't make out the shape of it. So just keep waiting with me. I will speed up the zooming out process a bit. You're welcome. So now we can see our galaxy, the Milky Way. Our galaxy is 13.6 billion years old and is 100,000 light years across. And at the very center of your screen, which is right here, this is where Earth is located in our galaxy. We are on the outskirts, the edge, and I find that very fitting for our planet. It's so easy to think our lives are the center of everything. I can't blame people for thinking that. In our day-to-day lives, it sure does feel like humans play an important role in everything we know. But even if we zoom out just a little bit so we can see our entire galaxy, we realize how insignificant our position in the universe really is. We're not at the center of our galaxy. We're not in some special location. So let's continue zooming out and see what the universe has in store for us. This is the Andromeda Galaxy. It's the closest galaxy to us. It holds roughly 1 trillion stars and is around double the size of the Milky Way. In around 4 billion years, these two galaxies will collide. Well, that's what we previously thought, but new data from 2025 brings uncertainty to this claim. We now believe that there's a 50% chance that these galaxies will collide and a 50% chance that they will barely miss each other. The Andromeda Galaxy is approaching the Milky Way at about 110 kilometers per second, and even if these two galaxies do collide, the chance of two stars colliding is basically zero because of the huge distances between stars. Here's a good analogy. The average distance between stars in the Milky Way is about the same as one ping pong ball every two miles. Thus, it is considered extremely unlikely that any two stars from the merging galaxies would collide. Look how many stars are inside this galaxy. On a passenger airplane, flying to the Andromeda Galaxy would take us 3 trillion years. That's 217 times the age of our universe. Let's keep zooming out. Space looks pretty dark from out here, but there's more behind the darkness than you would expect. Hundreds of thousands of galaxies all surrounding us. In the middle, this is our local group. It spans around 5 million light years across. The total amount of stars within this 5 million light years is 1.5 trillion. We are beginning to see the Virgo supercluster. This is 100 million light years across. Let's stop for a second, just to take it all in. The number of galaxy groups we are looking at is 200. This totals to around 2500 large galaxies. And within all of these galaxies combined, there are around 200 trillion stars. It would take a passenger airplane 130 trillion years to reach the edge of this region. Now, if we zoom out times 10, we will reach the neighboring superclusters. This is our universe within 1 billion light years. We are looking at 100 different superclusters. The total amount of large galaxies we are looking at is around 3 million. And the total amount of stars that are in this region is 250,000 trillion. That is 250 quadrillion solar systems. Our universe is much bigger than we can imagine. Today we estimate that there are 2 trillion galaxies in the observable portion of our universe. That amounts to 100 sextillion stars. To fly across our entire observable universe in a passenger airplane, that journey would take us 110 quadrillion years. That's 8 million times longer than the universe has even existed. But our tour of the universe wouldn't be complete without talking about something a little closer to home. Us. Humans. The very species that somehow managed to discover that all of this even exists. And although we are far from perfect, you have to admit, we've done some pretty incredible things. We've learned to look billions of light years into space, uncover the history of the universe, and understand the very laws that govern it. And even though this video is coming to an end, the real tour of the universe never does. It's happening right now. Every second of your life. Every place you go, every person you meet, every moment you experience, your own journey through life is a piece of this universe, a piece of this incredible work of art. When you really think about it, beauty isn't something that exists outside of our universe. The very feeling of beauty was born here. Within the universe itself, so thank you everybody for being here go out there and continue living your own tour of the universe
