@markmacthree3168! Thanks for sharing your perspective. The raid on Lindisfarne in 793 AD is widely documented as one of the earliest Viking raids in recorded history. Sources like the Anglo-Saxon Chronicle and Alcuin of York, a contemporary scholar, describe it as a Viking attack on the monastery, marking the beginning of the Viking Age. However, history can be complex, and there are always new interpretations and discussions about past events. If you have any sources or evidence about British involvement, I'd love to learn more-history is always more interesting when we explore different viewpoints!
Vikings wouldn't let their shields be ruined by being dragged through the water outside a boat for hours & days, their LIVES depend on those shields, they would at least have made something to raise up the shields out of the water.
Hi @sebbes333, you make a very practical point about Viking shields! The portrayal of shields hanging off boats is often more of a modern artistic interpretation. Vikings indeed valued their shields highly-they were critical to their survival in battle. Shield technology and its strategic use are well-documented in Norse sagas and archaeological finds, like those studied at the Viking Ship Museum in Oslo. Raising them above the water for protection during long voyages would have been a smart move. Thanks for sharing your insight!
They weren't viking viking aint a people its a description of doing something they weren't vikings they where going a viking 🤣 if ur going going to be handing out factual information make sure its factual and if you where going a viking you weren't trading
@@irongrid4682 Thanks for your comment! You raise a great point. Historically, the term ‘Viking’ indeed refers to the act of ‘going on an expedition’ rather than a specific group of people. The word comes from the Old Norse ‘vikingr,’ which describes a person participating in a raid or voyage. Many Scandinavians who went ‘a-viking’ were traders, explorers, and settlers in addition to raiders. Historians like Gwyn Jones in A History of the Vikings and scholars from the Viking Ship Museum in Roskilde have also noted that the term evolved over time to describe the wider culture and people associated with these seafaring activities. So, while it's true that ‘Viking’ wasn’t originally an ethnic or cultural label, it has become a general term in modern usage to describe the Scandinavian seafarers from this period. I appreciate you bringing this up-it’s always fascinating to dig deeper into the historical nuances!.
Yes & no. Yes, they were warriors, they plundered & so, Vikings were also traders, because it's hard to store all that plunder, better sell of some of it. Yes "Viking" is a description like "Fighter" or "soldier" or "carpenter" & so on, personally I have never heard anyone "Go viking" at least not in Swedish equivalent terms, however they did "go berserk", that was when Vikings drank too much or basically took "medieval combat drugs" and kind of "lost themselves to the dance of battle" for a while.
Great points, @sebbes333! The dual nature of the Vikings as both traders and warriors is fascinating. The distinction you make is spot-on-trading often came as a result of their expeditions, and they traded goods they acquired through raids or exploration. As for the terminology, the use of ‘going berserk’ is a fantastic example of how Norse language captured different aspects of Viking life. It’s interesting how these expressions and the mythology surrounding them still influence how we view Vikings today. Thanks for sharing!
Thanks for your question! There wasn't an actual camera capturing the event. The footage in the video is a simulation based on data from space missions like NASA’s Galileo and Juno, which have studied Ganymede but haven’t landed there. In 2029, the European Space Agency's Jupiter Icy Moons Explorer (JUICE) will conduct flybys of Ganymede, but no landing or camera placement is planned. So, no physical camera was used or retrieved-what you’re seeing is a scientifically accurate visualization.
Yes, that's correct! The asteroid that hit Ganymede is estimated to have been about 180 miles wide, which is indeed larger than the asteroid believed to have caused the extinction of the dinosaurs on Earth. Ganymede, being the largest moon in the solar system with a diameter of about 3,270 miles (5,268 kilometers) and a surface area of roughly 55 million square miles (87 million square kilometers), was able to withstand such an impact. On a smaller celestial body, this could have caused far more catastrophic damage!
Thanks for sharing your thoughts! I get that current events are super engaging, but space news like this can also be important for understanding our universe and how it affects life on Earth. Plus, it’s always fascinating to learn more about cosmic events. Appreciate you checking it out!
Glad you enjoyed the video! Sounds like Noah's flood makes for a fascinating story, but here we’re diving into the science of space events like the asteroid impact on Ganymede. Who knows, maybe cosmic events like this helped shape myths and legends! 😊
@@shawnfirouzian8487 myths and legends?? Where was the oldest earth rock found?the moon found from the alleged landing on the moon, from that video I mentioned just watch the first ten minutes and decide for yourself, with their scientific evidence of a meteorite or global flooding for the dinosaur fossil fields in the middle of the USA, just offering a different respective, remember as a child you were taught to walk and talk,but now as an adult your TOLD to shut up and sit down, good luck
@@brianedwards5792 I appreciate your different perspective, and you're right-it's essential to keep an open mind. While considering the vastness of scientific evidence and theories, it’s also important to remember that nature and the universe operate under universal laws that transcend both myths and scientific interpretations. As ‘Abdu’l-Bahá mentions in Some Answered Questions, nature itself follows a perfect and organized system, governed by a higher power that brings balance and order to all things (even events like asteroid impacts and floods). It’s this balance that invites us to explore and learn without being told to 'shut up and sit down.' Curiosity drives understanding, so thank you for sharing your thoughts!
@@shawnfirouzian8487 what has happened to curiosity, it's replaced with convenients,we know that the earth rotates but it's called a sun rise and a sun set, how convenient. Now I personally haven't seen a single show on regular TV on Jack Parsons satanic ritual in the Mojave desert in1946 of the opening of other dimensions (science agrees there are 10) and the fact that one of his partners was Ron L Hubbard,or the fact that there's restricted areas in the grand canyon but all funded expeditions were through the Smithsonian, the Americans Vatican I believe that my curiosity came late in life I know I didn't pay attention in school. Graduated in 81 but drank and drugged heavily till 06 . I must say it is enjoyable throwing out options and ideas out there for individuals to read and think about, and a lot saner than when you're with someone and you say did you see that? Referring to those infamous shadow people (lol) crazy right, but at the end of the day, there just words speaking of good song called names by an independent artist,makes his own beats just him and his girlfriend, she does all videos,if you never heard of him, throwing another gem see ya, thanks
Thank you so much! I'm glad you enjoyed it! I appreciate the feedback, and I'll definitely consider making longer videos in the future to explore even more fascinating topics. Stay tuned!
Great point! Jupiter's massive gravitational pull does act as a shield for the inner solar system, often redirecting or capturing debris that could otherwise threaten Earth. It's fascinating how it both protects us and interacts with objects like asteroids. In this case, Ganymede may have been in the path of one such object. Space is wild!
We are not a planet. A planet has cleared it's obit. We have annual meteor showers proving our orbit is not cleared even today. I want to see the proof the impact didn't happen on side facing us and STOPPED it from spinning.
1 Corinthians 15:1-4 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; 2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. 3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; 4 And that he was buried, and that he rose again the third day according to the scriptures:
Thank you for sharing that passage! It's always interesting to hear different perspectives. Let’s keep the discussion focused on the topic of the video, but I appreciate your input.
Great question! 99942 Apophis is a near-Earth asteroid that will make a close approach in April 2029, coming within about 19,000 miles of Earth. While it will be visible to the naked eye, current data suggests it poses no threat to Earth or the Sun. It's a fascinating event to look forward to, and astronomers will definitely be observing it closely! Stay tuned for more updates as we get closer to the date.
Thanks for sharing your thoughts! While it's true that some may feel space exploration doesn't have immediate impacts, discoveries like this help us understand our universe better and prepare for potential future challenges, such as asteroid threats to Earth. Knowledge gained from space missions can also lead to technological advancements that benefit humanity in ways we may not foresee today.
@@shawnfirouzian8487 This, or the next solar cycle Will create a invireorment uninhabitable by most humans. Just like All the other civilizations that had been here on Earth. Poles moving together at a accelerating pace, they have built labs on the intended area.
The clickbait title implies that this collision is "news," as in, a recent event. It never says when the incident happened. Hint: it was billions of years ago.
Thanks for your comment! You're right that the event occurred billions of years ago, but the 'news' aspect refers to recent findings and data that help us understand what happened. I’ll be sure to clarify that in future videos. Appreciate the feedback!
@@jeromehorwitz2460 "deceptive"?? hahahaahahahahaahahahahaaaa For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it! Looking Back in Time When we use powerful telescopes to look at distant objects in space, we are actually looking back in time. How can this be? Light travels at a speed of 186,000 miles (or 300,000 km) per second. This seems really fast, but objects in space are so far away that it takes a lot of time for their light to reach us. The farther an object is, the farther in the past we see it. Our Sun is the closest star to us. It is about 93 million miles away. So, the Sun's light takes about 8.3 minutes to reach us. This means that we always see the Sun as it was about 8.3 minutes ago. The next closest star to us is about 4.3 light-years away. So, when we see this star today, we’re actually seeing it as it was 4.3 years ago. All of the other stars we can see with our eyes are farther, some even thousands of light-years away.
I really hope the title is not misleading. The findings were most reported by Planetary scientist Naoyuki Hirata of Japan's Kobe University lanetary scientist Naoyuki Hirata of Japan's Kobe University: www.space.com/jupiter-moon-ganymede-asteroid-impact-tilt-axis
thanks for the CRT NO FACTS assertion..... ya never disappoint Data from the remote object is scarce making research very difficult, and so Hirata was the first to realize that the purported location of the impact is almost precisely on the meridian farthest away from Jupiter. Drawing from similarities with an impact event on Pluto that caused the dwarf planet’s rotational axis to shift and that we learned about through the New Horizons space probe, this implied that Ganymede, too, had undergone such a reorientation. Hirata is a specialist in simulating impact events on moons and asteroids, so this realization allowed him to calculate what kind of impact could have caused this reorientation to happen. In the journal Scientific Reports, the Kobe University researcher now published that the asteroid probably had a diameter of around 300 kilometers, about 20 times as large as the one that hit the Earth 65 million years ago and ended the age of the dinosaurs, and created a transient crater between 1,400 and 1,600 kilometers in diameter. (Transient craters, widely used in lab and computational simulations, are the cavities produced directly after the crater excavation and before material settles in and around the crater.) According to his simulations, only an impact of this size would make it likely that the change in the distribution of mass could cause the moon’s rotational axis to shift into its current position. This result holds true irrespective of where on the surface the impact occurred. source, KOBE UNIVERSITY
@@whysoserious7014 While some aspects may be speculative, they're based on solid research and data from planetary scientists. These findings help us understand the history of our solar system, and ongoing studies will continue to refine our knowledge. Science often starts with speculation, but it's built on evidence and research over time. Thanks for sharing your thoughts!
The findings were most reported by Planetary scientist Naoyuki Hirata of Japan's Kobe University lanetary scientist Naoyuki Hirata of Japan's Kobe University: www.space.com/jupiter-moon-ganymede-asteroid-impact-tilt-axis
Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a Kobe University researcher realized that the Solar system’s biggest moon’s axis has shifted as a result of the impact, which confirmed that the asteroid was around 20 times larger than the one that ended the age of the dinosaurs on Earth, and caused one of the biggest impacts with clear traces in the Solar System. Ganymede is the largest moon in the Solar System, bigger even than the planet Mercury, and is also interesting for the liquid water oceans beneath its icy surface. Like the Earth’s moon, it is tidally locked, meaning that it always shows the same side to the planet it is orbiting and thus also has a far side. On large parts of its surface, the moon is covered by furrows that form concentric circles around one specific spot, which led researchers in the 1980s to conclude that they are the results of a major impact event. “The Jupiter moons Io, Europa, Ganymede and Callisto all have interesting individual characteristics, but the one that caught my attention was these furrows on Ganymede,” says the Kobe University planetologist HIRATA Naoyuki. He continues, “We know that this feature was created by an asteroid impact about 4 billion years ago, but we were unsure how big this impact was and what effect it had on the moon.”
@@jjtheyoutuber7341 That's a great observation! While Jupiter does act as a protector by pulling in debris that might otherwise head toward Earth, its gravitational pull can also redirect objects toward its moons, like Ganymede. So in a way, it’s a bit of both-protector for some, but maybe not so much for its own moons!
@@anthonycphillips2430 Haha, I’m pretty sure Jupiter’s gravity has been doing its thing for a lot longer than any political figure! But it’s always good to keep the conversation lively!
The belief that the Earth is flat is contradicted by centuries of scientific evidence. From the way ships disappear hull-first over the horizon to satellite imagery and space exploration, all observations confirm that the Earth is a sphere. The principles of physics, like gravity, and the ability to travel around the world without falling off an "edge" further disprove the flat Earth theory. Subscribe for a short video providing evidence against the Flat Earth philosophy.
I really liked this process. This is the most difficult part of studying differential equations and it's not really done practically in my course - we're just given the DE which we then solve... which isn't super challenging. I think the only way to really get a grasp on them is to figure out the equation slowly and with reasoning like this group did. Good job and thanks for posting!
Thank you for this video! It is helpful. I was just wondering are your students writing backwards on a clear glass board or writing the normal way and the screen is flipped? The writing part amazes me.
It was the first time they were seeing the problem. What you can't hear much is the conversation with the TA who is trying to guide them towards the right answer.
Video description says that you haven't altered the video in any way, however the person behind you has apple earphones, and the mic/volume control box should be on the right side of the earphones, but in the video they are on the left! This proves that you mirrored the video feed, and actually are a right-handed person with a watch on the left-hand writing on the glass left-to-right as normal.
Coming from a finance background this video helps me understand differential equations; a subject that has never made sense to me because it is taught in its pure form. I wish professors would make more videos like this - real world application of diff eqs (economics, biology, engineering, etc)
