A Mysterious Object Punched a Hole in the Milky Way, Scientists Are Confused

Space is full of mysteries that have remained unsolved for centuries. But recently, the cosmos has baffled the world with a new, scary abnormality. Apparently, something is tearing holes in the Milky Way, the galaxy that contains our Solar System! 😮 What if the hole in the Milky Way was torn by a supermassive black hole like the one that dwells in the center of our galaxy? If it was, it’d be a pretty scary scenario.

If these two black holes got too close, they wouldn't be able to escape each other's gravity, and a collision might be inevitable. And it would be an extremely violent event. But the thing is that the telescopes failed to find the source of the damage. So what could this unseen bullet be? Scientists have several theories.

SUMMARY:
- This year, Harvard scientist Dr. Ana Bonaca noticed a weird disturbance in our galaxy's stellar streams. A stellar stream is a line of stars that are moving together through galaxies.
- One day, Dr. Bonaca noticed a gap in the stream, and this gap had a strange ragged edge.
- One theory suggests that the intruder is a stray star. However, the hole is too enormous for this idea to sound plausible.
- Luckily for us, there aren’t any supermassive black holes in the vicinity, so this theory fails to explain the mysterious bullet-hole phenomenon.
- Naturally, astronomers have continued their observations. But what baffles them is that there’s no large object made from ordinary, light-reflecting matter moving away from the bullet-hole.
- What if it was dark matter that harmed our galaxy, and what if it reached Earth? Unlike a stream of regular matter, dark matter wouldn't see the Earth as an obstacle. It would just pass through. But that's not the most amazing part!
- However, Dr. Bonaca still doesn't rule out the possibility that the intruder is a luminous object that, after tearing a hole in the Milky Way, is hiding somewhere in the galaxy.
- The intruder could’ve been moving at an incredibly high speed, and wouldn’t have to be very massive to tear a hole in the stellar stream.
- The edge of the galaxy can even contain traces of a "ghost" galaxy - one that's older than our Milky Way!
- Curiously, the astronomers who discovered the "ghost" galaxy, which is a satellite galaxy of the Milky Way, can’t explain its origin and nature. Named Ant 2, the galaxy was dubbed "ghost" because it's weirdly dim.

Random YouTube Video Generator

 This site provides links to random videos hosted at YouTube, with the emphasis on random.

 The original idea for this site actually stemmed from another idea to provide a way of benchmarking the popularity of a video against the general population of YouTube videos. There are probably sites that do this by now, but there wasn’t when we started out. Anyway, in order to figure out how popular any one video is, you need a pretty large sample of videos to rank it against. The challenge is that the sample needs to be very random in order to properly rank a video and YouTube doesn’t appear to provide a way to obtain large numbers of random video IDs.

 Even if you search on YouTube for a random string, the set of results that will be returned will still be based on popularity, so if you’re using this approach to build up your sample, you’re already in trouble. It turns out there is a multitude of ways in which the YouTube search function makes it very difficult to retrieve truly random results.

 So how can we provide truly random links to YouTube videos? It turns out that the YouTube programming interface (API) provides additional functions that allow the discovery of videos which, with the right approach, are much more random. Using a number of tricks, combined some subtle manipulation of the space-time fabric, we have managed to create a process that yields something very close to 100% random links to YouTube videos.

 YouTube is an American video-sharing website headquartered in San Bruno, California. YouTube allows users to upload, view, rate, share, add to playlists, report, comment on videos, and subscribe to other users. It offers a wide variety of user-generated and corporate media videos. Available content includes video clips, TV show clips, music videos, short and documentary films, audio recordings, movie trailers, live streams, and other content such as video blogging, short original videos, and educational videos. Most content on YouTube is uploaded by individuals, but media corporations including CBS, the BBC, Vevo, and Hulu offer some of their material via YouTube as part of the YouTube partnership program. Unregistered users can only watch videos on the site, while registered users are permitted to upload an unlimited number of videos and add comments to videos. Videos deemed potentially inappropriate are available only to registered users affirming themselves to be at least 18 years old.

 YouTube and selected creators earn advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Music and YouTube Premium, subscription services respectively offering premium and ad-free music streaming, and ad-free access to all content, including exclusive content commissioned from notable personalities. As of February 2017, there were more than 400 hours of content uploaded to YouTube each minute, and one billion hours of content being watched on YouTube every day. As of August 2018, the website is ranked as the second-most popular site in the world, according to Alexa Internet, just behind Google. As of May 2019, more than 500 hours of video content are uploaded to YouTube every minute.

 YouTube has faced criticism over aspects of its operations, including its handling of copyrighted content contained within uploaded videos, its recommendation algorithms perpetuating videos that promote conspiracy theories and falsehoods, hosting videos ostensibly targeting children but containing violent and/or sexually suggestive content involving popular characters, videos of minors attracting pedophilic activities in their comment sections, and fluctuating policies on the types of content that is eligible to be monetized with advertising.
