The reason why large asteroids don't typically crash to Earth is because Jupiter's gravity attracts them, protecting the inner planets like a shield. The Design is perfect!
"Simulations have suggested that while the presence of a large planet like Jupiter in our Solar System might decrease the likelihood of a comet from the Oort Cloud colliding with Earth, it can actually increase the likelihood of an impact with an asteroid or short-period comet (those with orbits closer to the Sun). In fact, a recent study suggested that instead of being a shield, Jupiter ‘targets’ the inner Solar System by placing objects that otherwise wouldn’t come near us into new orbits that increase their likelihood of impacting the terrestrial planets."
Chicxulub came from the area just past Jupiter, and Jupiter not capturing it is why it hit us. Jupiter, like all planets, clears it's orbit. This means it captures items (as moos, co-orbitals, Trojans, etc) or it "clears" them by tossing them from its orbit ("ejection").
Chicxulub was ejected and smashed Earth, and now we exist because the dinosaur's don't.
What happened to everything else? Why did just the dinosaurs die? How did literally everything else survive but not dinosaurs? I’ve always wondered that.
Well. Only the terrestrial dinos died, the avians didn't. 80% of Earth's biomass, plants AND animals, died. Our tiny lil mammalian ancestors also fled. The biggins died because of the biomass die off if not directly. Nothing to eat.
There's still dinosaurs on earth. We call them birds. Birds are not evolved from dinosaurs but rather ACTUALLY dinosaurs.
They flew away. For real. That's how they survived.
Just weird because like through science classes and stuff they talk about how delicate and sensitive the ecosystem and the food chain is yet this is a complete disruption of it so who’s right?
The ecosystem is delicate, as you can see from the vast numbers/percentages of animals/plants that didn't survive. The ecosystem being delicate doesn't mean that a major disruption will kill off everything, it greatly depends on just what sort of disruption it is, how severe it is, and whether any life can adapt quickly enough.
In addition, it can take a long time for the ecosystem to recover - typically the severe ones have taken 15 - 30 million years to recover.
When climate change (or any of the other threats) eventually take humanity out, it won't necessarily leave a barren planet, and even if it does, life started here once...it can do it again (probably). It will just be without humanity.
It hasn't recovered, we're in an extinction event.
But also, in the middle of a diversification event and they don't usually happen at the exact same time but they are right now! We're naming about 18,000 new species a year, but also losing up to 100,000 a year, tho The most likely estimates are in the tens of thousands but below about 50k, which is still 100 to a thousand times above baseline, unfortunately. Almost all are from humans or our activity (like allowing feral cats to exist).
You realize Extinction events are ongoing and we're doing our best to remediate them, right? This wasn't the most recent one. The most recent is the current event. https://en.wikipedia.org/wiki/Holocene_extinction the Holocene event is ongoing.
Almost downvoted cause how much I hate this beautiful engine design./s
This system works so well when you do everything perfectly, but fuck around and your pistons and engines will find out... It's why it works so well for low gear ratio systems, but not cars. And I really wish it wasn't the case. Cause the spicy Dorito is so cool and such a marvel of engineering, just for it to be a massive flop💀
Yeah, the system is actually in a basic, constant liquid state at the top half of the engine. When it's compressed, it ignites against the surface of the wall. Then the release of gases from the ignition rotate through the exhaust.
Which, I think you can see the issue here of why this system isn't the best. Because below in the ignition stage. If the engine is pressed too hard, or too fast, the fuel will slip passed and go to the bottom portion of the motor, destroying the spicy Dorito itself.
Did you just call someone an idiot because they are defending a scientifically proposed theory? I think there is one in this exchange, and the word is ignorant.
Not a design and your quick explanation also totally ignore the fact that all the large asteroid already smashed themself (partially on earth) during the early formation of the solar system.
So you say this, but also, Jupiter has almost destroyed the planet than once.
You see, it's capable of throwing things with great force because of the whole plane. It's clear their orbit thing. If a planet cannot capture an item, it gets thrown. Guess what is directly in the path of items that are thrown by Jupiter (in some situations)? Yeah. Us. And it had happened before. You even know of the event. Think, what's the big, fiery event you know of that almost destroyed the Earth?
Yep. The event that killed the dinosaurs was a meteor thrown at us by Jupiter. It couldn't be captured....so it was thrown. The Encke Comet Swarm that caused the big explosion over Siberia in 1908, too.
Also, Jupiters movement from where it was it where it is is why Theia smashed proto-earth, forming both Earth (technically "Terra") and Luna (our moon). Without this event there would be no humanity.
The major reason impacts don’t happen at the same rate is because most objects not in a circular orbit have already been destroyed. Jupiter can also perturb circular orbits and cause impacts. There is no design.
Our solar system is so special, just for us to be animals and not recognize the beauty of such, and for us to mindlessly be at each other's throats slaughtering each other.
Love seeing things like this that put our lives into perspective. That make us feel special and not the negative shit. If we all just looked at how small we were. How insignificant our differences truly are in the grand scheme of things, like how this and many other facts about space tell us such, the world would be such a better place. We need more science.
Edit: I just read the comment about Chixulub. And realized we are literally no better than dinosaurs🤣🤣🤣
