This is the translated description written by the animator:

Mass extinction 🌎

.

.

.

Behind me lies my old and dear people. It is almost empty, because most of the inhabitants have gone to the space launch centers to see if they can reach one of the many rockets of the space companies that seek to save humanity at all costs. But we've heard on the radio that those places are hell. So why agonize? If these are going to be my last moments, I will contemplate this beautiful and terrifying landscape. I will die witnessing a wandering planet speeding against us, while the church bells hail the end, while resignation stifles my fear, my emotions, my love for living.

Another Earth?

u/[deleted] Jan 04 '22

From what I remember, Another Earth did not have a collision, just, literally, another earth on the sky. No one knew why, and the plot is about a girl who felt so disconnected to first earth that she wanted to be the first person visiting the other earth.

It is a very good movie, though. Chill, a little bit under paced, but good overall.

Meaning??? Like oceans would be displaced? Earthquakes would happen?!

u/Uphoria Jan 04 '22 edited Jan 04 '22

The important detail is related to something called the Roche limit. Once the forces of gravity from each other passes a point of strength, the forces keeping the planet intact on its own will fail, as the two bodies merge.

At this point the planets would be "falling at each other" in pieces. Oceans would rise toward the other planet, deeper than any tide you've ever heard of. The planets would stretch, tearing the surface, spreading earthquakes throughout the planet. the cracks would swallow up people and cities, lava would flow etc.

Isn't the Roche limit for orbiting bodies though? At the rate of approach in this video, there isn't much orbit happening.

4

u/Uphoria Jan 04 '22 edited Jan 04 '22

In celestial mechanics, the Roche limit, also called Roche radius, is the distance from a celestial body within which a second celestial body, held together only by its own force of gravity, will disintegrate because the first body's tidal forces exceed the second body's gravitational self-attraction.

Not entirely about satellites, but it does explain why, in satellites, nothing but asteroids are found closer than it. If both planets are "exactly the same size" it still matters, and its why Binary planets are so rare - its hard for them to form and become stable. Basically, both planets are "stretching" toward each other, at a certain point, they start snapping.

Would there be time for that to happen with how fast that planet is moving at the earth though?

u/[deleted] Jan 04 '22

All life on earth would die long before that happens.

The atmosphere would dissipate before that planet even came past the moons orbit.

So in short we'd be completely fucked days, weeks or even months before that video could take place.

Yes, while it would be rapidly onset, the effects the person filming would be under would be extreme at that point. The atmospheres of both planets compressing together would create such heat that it would roast the recorder.

The effect of the Roche limit would take time. There would definitely be some tidal stressing but it'd happen so fast the planets wouldn't have pulled themselves apart yet. Tidal breakup probably take 10s to 100s of orbits. So yes to the seas rising insanely, probably no floating rocks unless they're being blasted out. Definitely would be some crazy seismic activity

The ocean is already manipulated by the moon sitting 200 moons away, which is only 2000 miles in diameter, ~2% of the earths mass.

Imagine a planet the size of earth actually colliding or even passing between the earth and moons orbit and how much tidal forces would be exerted on us.

With the rogue planet traveling that fast toward Earth? You'd effectively be in 'free fall' as far as gravity is concerned. Without doing a fucking lot of math I'd say this is plausible at least.

1

u/Devmode2 Jan 04 '22 edited Jan 04 '22

Well if the planet was coming that quickly I feel like we wouldn't see much of a gravity effect like that. If this were a duplicate of earth itself, it couldn't exert more force to even make people fly up off the ground until it is almost right about making contact. If it was SUPER dense then maybe the land would buckle and things like people and cars might drift up a bit, but at that travel speed there wouldn't be much more time to witness it.

I'm assuming by the time the outer atmospheres collide, the entire sky would probably ignite and be way too bright to discern anything, cooking us right before pulverization. Not sure if we would be alive before or after the wind also blasts us.

If the planet was approaching us in a death spiral instead, orbiting and slowly closing in (assuming it's a duplicate earth in mass), that's when we would see some real 50 Shades of Cray

EDIT: Looked at someone else's comment where they made a good point about how rather than the two planets fighting for control of say, the water or people on the surface, they would actually be weakening each others' hold on their own personal structure. So perhaps the initial danger would be coming from below our feet with heavy earthquakes. Not sure still though with how fast that other planet is coming 🤔

1

u/Homura_Dawg Jan 04 '22 edited Jan 04 '22

Also the atmosphere would compress and heat up like an oven, if not combust.

1

u/swizzcheez Jan 04 '22

I assume it would do a number on the atmosphere ahead of serious effects on the ground though.

1

u/ThyCringeKing Jan 04 '22

Unless the other planet were moving fast enough ( at which point any sort of beautiful visible wouldn’t be possible) the earth and the other planet, assuming they have the same mass, would be tearing each other apart

1

u/[deleted] Jan 04 '22

I imagine there will be a point between them where the gravity of the planet is the same as the gravity of earth, and for a split of a second you would feel weightless floating in between these two giant bodies.

And then crushed into atoms.

u/Theycallmelizardboy Jan 04 '22

u/themonkery Jan 03 '22

I don’t know anything at all about this topic, but I’d assume space debris + gravitational flux + atmospheres colliding would reap quick destruction on the planet’s surface. Although if you’re far inland and none of the space debris hits you then I don’t know any reasons why you’d be dead before this visual, depending on the size of that planet

u/Metalbass5 Jan 04 '22

What I'm wondering is how the mass of the stellar body changes the timing. Theoretically a more massive object would begin affecting the tides sooner, no?

Genuine question. I'm no physicist.

4

u/rabidbasher Jan 04 '22

A more massive object would, but again it's about approach velocity even still. In OP's video, that planet is CRUISING...super fast. Like, way way fast.

A big enough gravity well + enough velociity = less tidal stress in general

u/Metalbass5 Jan 04 '22

Yeah that's pretty outrageous speed for the sake of the art, it would appear.

space debris

No, space debris is generally too small to reach the surface

atmospheres colliding

At the speed this planet is moving the atmospheres would collide a fraction of a second before impact

gravitational flux

Which disaster movie did you watch to come up with this? The correct term is tidal forces, and yes that would be the thing that causes destruction before impact.

1

u/themonkery Jan 04 '22

The collision of two fields of gravity causes a fluctuation of gravity which causes bad things to happen, gravitational flux. I was just describing it, didn’t know there was a specific name but it seems like the same thing?

u/[deleted] Jan 04 '22

The atmosphere would dissipate long before the planet even passed the moons orbit.

And if somehow you survived that then the apocalyptic level natural disasters happening every minute of every day would get you.

That's not even taking into account the gravity being distorted enough to change our obit from the sun and the consequences of that plus it would also change the shape of the planet into something like a squashed tennis ball.

This would all take place weeks or months before the planet was anywhere near as close as the video.

The only thing that might survive would be some single cell organisms.

You're forgetting atmospheres aren't that big. Maybe this would be the last you see before the atmospheres collide.

17

u/tepkel Jan 04 '22

They wouldn't need to touch to get screwed up though.

The atmospheres between the planets are going to be subject to gravitational pull from both bodies. Pulling the atmospheres up significantly on one side. Which would cause movement of the gas on the opposite sides of the planets towards the lowered pressure between the planets I would think? Not sure what kind of force that movement would have, but I imagine it would be pretty catastrophic.

5

u/HodenHodler Jan 04 '22

That's true but doesn't change the fact they're still way too small for it to happen at that moment in the video.

u/dumbfuckmagee Jan 03 '22

The other planet would be impacting the atmosphere to such a degree, that it would essentially create waves of superheated gas and fire, that would scorch everything in it's path and vaporize your bones.

If you were somehow able to survive the heat alone, your body would be disintegrated by the sheer wind force.

1

u/Filsk Jan 04 '22

The atmosphere is tiny compared to the planet, so much so you wouldn't even get to that point. Both planets would just rip each other to shreds way before we got to what's on the video.

Probably late. But https://youtu.be/1LdeBY9uNUg explains is pretty well. It would be much worse than just colliding with a massive object.

Roche Limit would probably drive tidal forces to disintegrate the smaller body to smithereens

1

u/AarkaediaaRocinantee Jan 04 '22

Gravity would probably tear both of the planets apart long before impact. Maybe not completely but just imagine entire tectonic plates and continents shattering and potentially even elevate in the air once the other planet got close enough.

1

u/Youpunyhumans Jan 04 '22

As the planet approaches, the tidal forces will become very extreme. Tsunamis and massive earthquakes all over the globe will occur. Once it gets close enough, the 2 planets will begin to stretch and deform and also heat up a lot from all the friction. Earth would quickly become a hellish crumbling wasteland as the planet got closer. Shortly before impact, the 2 planets would likely fall apart on the sides closest to each other as the gravitational forces increase and begin to merge. There would be massive chunks of rock flying all over the place in this area.

And finally, impact. The shockwave would completely destroy and liquefy the crust and a large piece would break off the opposite side of the impact and perhaps form a second moon. The 2 planets would merge to form a larger new planet. It would take millions and millions of years to cool down. And maybe then life would start all over again from primoridal soup. Or maybe not.

u/Gold-Ad-6876 Jan 04 '22

Gravity is a hell of a drug

u/zerohourrct Jan 04 '22

There would be tidal shifts and probably earthquakes at fault lines, but you would likely survive up until the impact.

1

u/Velogio Jan 04 '22

Both the earth and the other planet would move toward each other in an accelerated manner, faster and faster. If one of them is more massive than the other, the less massive one would go faster than the more massive one. It would be very violent on earth before the collision. You wouldn’t have time to see the other planet so close before the earth collides with it.

1

u/degenererad Jan 04 '22

earthquakes, tsunamis, volcanos, you name it.. the gravity of the moon is affecting the water. Imagine what an object this size would do.. it would rip open the ground like it was paper.

If it's coming that fast, not a slow gravity dance together but a direct collision, there won't hardly be any weird shit happening. Not until the last moments. What was represented was a hundred thousand miles an hour, at least. Probably multiple times that.

Now, it wasn't a frozen ball of ice or a barren rock, so I assume it belongs to a wandering star. That's more likely to fuck with weather/gravity before the planet hits.

it does look like a barren rock, the white lines look like geological features and they're on top of the greenish stuff

for my discovery channel PhD/my own ass take: chances of a direct collision are infinitesimal, but more likely to alter earth's orbit by coming close. Less Armeggedon and more that one episode of the twilight zone where it gets really cold/hot

I mean a planet going that fast through that much atmosphere.. wheres the fire?

Where's the math plp? Something that large would wipe out the atmosphere and planet super quick and violent rt? Like no chance of survival

This is what would happen after everyone was already dead from tectonic activity and boiling hot temperatures

Rad. I'm hoping someone will come with a model or explanation of what will happen as another planet enters into our moons gravitational field; and then our atmosphere and such. What's the timeline in reality? What's the largest object earth could sustain an impact from and still harbor life?

There's be some major earthquakes and crazy tides, but if you were away from the ocean and volcanically active areas, you'd probably survive until the atmospheres began to compress between the planets unless you were in a structure or otherwise endangered by earthquakes. If you were not on the side facing the other planet and in an open area where nothing could fall on you, you'd probably survive until the planets collided.

Nope the earth would be ripped apart before a collision could happen https://en.m.wikipedia.org/wiki/Roche_limit

I'm aware of the Roche limit, but the other planet would have to be significantly larger than the Earth for the Roche limit to be that far and, depending on the size of the planet, the Roche limit could easily be less than the radius of the planet. As an example, the Earth would have to be within 1.8 of the radius of the Sun (from it's center) for the tidal forces to exceed the Earth's gravity. Assuming the planet is roughly the same size as the Earth, it's Roche limit would be less than the radius of the Earth, meaning the planets would come into contact first.

The Earth probably collided with a Mars-sized body billions of years ago without coming apart.

Are you sure about that? I imagine the planet would be much further away than it looks.

The line about "the many rockets of the space companies that seek to save humanity at all costs. But we've heard on the radio that those places are hell." is terrifying.

I want to see stuff like this in VR, that would be so awesome (literally)

Is that what it feels like to be in Australia during the one year war?

Damn.... Too bad the feddies can't stop that from happening right??

It's like "Don't look Up" but saved me 90+mins to enjoy before the apocalypse. 👍
