Science Documentary: Big Bang, Inflation, Multiverse, a Documentary on Cosmology
The Big Bang happened 13.7 billion years ago, but we do not know
what or why it happened. So far we can only speculate, but we do know that the Big Bang gave us all the ingredients that make up our universe. All the energy and matter that exists in our universe was created during the Big Bang.
Cosmology is the study of the origin of the universe and the way in which it evolves over time. Since the speed of light is a constant, this helps us to study the universe. When we look at stars and galaxies through a telescope, we can determine their age by measuring the time it takes for their light to reach our eyes. This measurement of time is light years.
Studying cosmology has provided us a concise picture of the universe from its origin in the Big Bang all the way up to today. But there are several questions that we have yet been able to answer. The first question asked is whether there was anything before the Big Bang. Did space and time exist prior? Another question is what is Dark matter. Dark matter is abundant in the universe. In fact, there is more Dark matter than regular matter in the universe. Dark matter interacts with gravity but not with light.
When scientists observe the expansion of the universe, they observe that the expansion was accelerating. This means that the galaxies were flying away from each other faster and faster. It is believed that the cause of this acceleration is due to Dark Energy.
Perhaps the biggest question is whether there is life somewhere else in the universe. Our technology to this point has not allowed us to discover life on other planets, but over the next several decades, scientists believe that this question may be answered.
Is our universe part of a multiverse? The standard Big Bang theory suggests that the universe began roughly 13.7 billion years ago from an incredibly hot dense state referred to as a singularity. But Inflationary theory suggests that the Big Bang was not the beginning of existence , but it was our own local Big Bang in a much greater multiverse which already existed.
The standard Big Bang theory does not describe what banged or why. It merely describes the aftermath of the bang. This means that the explosion of the Big Bang had already occurred before the theory begins.
Inflation is a theory that modifies the Big Bang theory, but is not intended to replace it. Although the Big Bang theory is a truly successful theory; inflation is the "bang" portion of the Big Bang theory.

This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥
Origins of the Idea 🌱
The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠
Challenges Faced 🤔
Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.
Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍
Creating Truly Random Links 🛠️
The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
About YouTube 📺
YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟
Content and Users 🎵
Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.
While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.
Monetization and Impact 🤑
YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.
As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
