It's crazy to think that this was just about in time for animals to actually see it. Like sure life was a lot simpler back then but they did have eyes and brains and probably at least sometimes looked up above the surface towards the sky, even if by accident.
I wonder if these rings had anything to do with the alleged Deniliquin impact structure in Australia. It is not confirmed, but if it’s real, it would be the largest confirmed impact crater on Earth (larger than Vredefort and more than twice the size of Chicxulub), and it would have struck at the end of the Ordovician. It also would have almost certainly caused the extinction event at the end of that period.
Ever since tumblr collectively learned that sharks are older than Saturn's rings (if young-ringer theorists like MIT are to be believed), I have accepted that planetary rings may be merely temporary and even fleeting. Never considered that it might have happened to Earth though! Such fleeting rings indeed. What an amazing universe this is, always something new to learn.
We did know that Earth did have an another ring before this one - the one that formed after a Mars-sized planet hit the Earth and which formed the Moon.
Observing an object breaking up while crossing the Roche limit would be quite interesting. Possibly even a spectacular event. Is there already a video of this happening?
Roche limit is controversial, but works for most asteroids. Most asteroids aren't rocks - they WERE rocks, but were shattered, and are now piles of rubble. They still hold together by gravity. ... when the gravity isn't countered by someone else's gravity, which is what Roche handles.
I get that an equator impact path back then would not be where our equator is now. However, with all the shifting and jostling of tectonic plates how could the impact path shown on our current topography be a straight line as shown in your graphic?? Wouldn't the path be at least a somewhat jagged line because plates have moved since then?
Not that we should not be working towards lowering our carbon footprint, but its nice to hear the planet has survived hotter. Something assuring about that as long as we keep putting our best foot forward.
it makes me sad that the way scishow talks about ads has gotten kinda… desperate sounding? like they’re having financial troubles. i can’t handle the idea of this channel going anywhere
3:51 The Roche Limit only applies to objects orbiting another, but your explanation and graphic only illustrate on object approaching another, which suggests that it applies to an object merely passing by a massive body, which isn’t quite right.
Just saying hi to hopefully help fix UA-cam’s broken algorithm! And to say ALL content on YT needs equal monetization. Great stuff SciShow keep it up please.
Interesting, though you'd probably expect debris orbiting in the plane of the solar system to tend to impact within 30⁰ of the equator half the time so I don't think that's a good argument (though other arguments maybe are). Remember, sin 30⁰ = 0.5.
The thing is, once that debris is trapped by Earth's gravitational pull, it would align with the planet's rotational axis, orbiting along Earth's equatorial plane. This is how rings around Saturn, Jupiter, Uranus, or Neptune, form. Uranus is a particularly good example, as its axis is flipped by about 90º, and even its rings align with such inclination.
reminded me of my old favourite comic schlock mercenary. having a artificial ring made of satellites. originally for managing earths temperature a bit with light. some species made adjustments to use it for guidance.
Worth noting that Mars not featuring any evidence of this particular meteorite bombardment doesn't necessarily mean much. Mars is sometimes on the opposite side of the sun from us, so an asteroid that broke up and deorbited from the asteroid belt could just miss Mars entirely and hit Earth, as long as the pieces remain in a relatively coherent blob of material (Like how Apollo 13 and the debris field from its tank explosion were flying in the same direction at the same time, so they had to speed up a bit in order to accelerate out of the debris and give the navigational equipment the clear view of the stars and such it needed to properly calculate their position) As long as that blob of debris crosses Mars's orbital altitude while Mars is sufficiently far away in the loop, it'll pass by with very little effect. The Moon, on the other hand, being *our moon* is a much bigger problem - This is less dodging a shotgun fired into your house by not being in the room the shotgun was shot into, and more a sniper taking a shot from a couple of miles away and successfully hitting a target (Earth) while not hitting the person they were walking arm in arm with (the Moon) - still in the realm of possibility, but far, far less likely to happen.
*There is just one thing you never mentioned: the Moon. Its gravity would have had a huge impact on the formation, form, behavior and longevity of such "rings"-if it would allow their formation, at all.*
5:56 It’s pretty obvious that continents would change, shift around, get submerged, etc. but why would the position of the equator-which has to do with the Earth’s axis of rotation-shift so dramatically, assuming that map shows its position accurately?
That isn't showing the equator. It shows the line of debris along a path that would have been over the equator millions of years ago. The equator didn't move. The tectonic plates moved
@@timperry6948 Right, it’s showing the path that would have been over the equator millions of years ago. Assuming that map is showing the relative position of the equator at the time against a present-day map, why would the equator have shifted-or, put differently, why would the axis of the Earth have shifted? (It seems like it couldn’t have.) If the map is showing the equator and that position _hasn’t_ moved, how would the present-day continents be where the map shows? (They wouldn’t be-they wouldn’t even be anything like their present-day shapes.)
@@jeff__w I agree with you that it is a little bit awkward that according to that graphic, it may appear like America and Europe position relative to each other hasn't change in such a long time, so I went to search a little bit. Here I link you to a video showing the tectonic drift, and yes, it tuns out that the Canadian shield, Greenland and northern Europe were on the equator almost in the same relative position: ua-cam.com/video/gQqQhZp4uG8/v-deo.html
@@adrianchezorts Thanks, that's great. I'll check it out. The use of the present-day map to show what _would become_ the modern land masses for an Ordovician event is not only misleading, it's just incredibly confusing. But now that you've explained it, I can sort of see it. _Edit:_ It's not the present-day map that's confusing-that's just misleading-it's the orientation of the equator on that map. But I guess they were showing in present-day terms where the craters were located.
One thing that is missing from this explanation is the effect of micrometeors would have. There would be a lot of them from a break up of a large asteroid and they would rain down all over the Earth. They would deliver minerals to a large parts of the oceans. This would encourage plants growth, which in turn would encourage animal growth. And with an explosion of growth would come an explosion of diversity.
"You're the one with aggressive dogs" these dogs aren't but her unleashed dogs could be stressless and killed by a leashed dog that is aggressive and it would still be her fault
Functional for us; majorly dysfunctional for biodiversity of the planet in general, in the long run. (once we came along and messed it all up :P) This is super cool though! Thanks for the video!
Rings can also protect a planet's atmophire from Radiation . An ice Based moon leaving a ring would catch material blowing off when on the dark side and rain it back down on the sunny side
I wonder what degree of difference there is between an asteroid that becomes a pretty, orbital ring and one that smashes a giant crater into the planet.
Within 30 degree of our equator. Isn't it just roughly Earth's surface facing our Solar plane? And there are obviously more asteroid at that plane than outside, right?
Asteroids coming from the plane of the solar system would be more likely to hit at higher latitudes or be evenly spread than bodies falling from a ring around Earth's equator, both because the require angle is less and because those asteroids have much more inclined and eccentric orbits.
Just imagine the impact it would have had on human culture as a whole, the way human brains would have developed, hell the way brains in GENERAL have developed would be different. The way we perceive time would be radically different as would religion. It'd be interesting to see the way people react when it turns out the rings aren't actually an all powerful god xD
"Within 30° of the equator" includes half of Earth's surface, so this evidence is perhaps not as strong as it might sound. Edit: the paper's abstract says "∼70 % of exposed, potentially crater-preserving crust [lay] outside this band". I suppose the real test would be to compare with alternative scenarios not involving formation of a ring.
When earth was hit by another planet billions of years ago, that debris probably spun around the earth forming a ring set as well, eventually forming into the moon.
Scishow did a video on the newest simulation of the birth of the Moon (the impact of Theia), which hypothesises (quite beautifully) that the moon was almost completely formed within a very short timeframe (24hours, I think? Shockingly quick).
Could there be any correlation to the Iodine cycle and the sudden shift that allowed the ozone the develop which provided protection for land animals? Anything about the chemistry of those rocks that would make them reactive with iodine, shifting the balance? The timing seems about right...
I don't know, but I imagine different sedimentary rocks form in the different water levels. For sure different animals and plants leave different fossils.
what is wrong with UA-cam? I haven’t seen sishow videos in like over a year. I am subscribed. I watched most of them But because it’s been over a year. I forgot you guys exist.
As I understand it, when the Sun swells to a red giant it will push the moon into the Earth's Roche limit where it will break apart and form a ring around the Earth, but I don't think I'll be around to see it. :(
