Can We Combine All Planets Using Roche Limit? - Universe Sandbox² 

This channel is something like 85% informative, 15% cosmic demolition derby. Love it. Please maintain this healthy ratio.

"It just ate the whole Venus". Wife walks in "What are you watching?" 😂

Universe sandbox is such a fascinating simulator.. I'm so glad I have it

I'm waiting every day on a new video from you. It's so educational and fun to watch!

anton, can you please make a video about terraforming pluto. You can make different versions. 1 will be in its normal distance from the sun. 2 you can place pluto in the goldelock zone.

OH MY GOD IS THAT A KIRBY REFERENCE

I wish this fragment system could return to the game now, it was so epic and it could simulate the formation of moons planets and even stars if you want to waste your time.

I would love that you continue showing us a little bit of math or formula like in this video

*venus has mars and mercury in it* well my ex also had 2 in her

Anton love your show and the new program!

By far my favorite RU-vidr this guy is awesome!

Then it will be called Meunsrtharsupiturnanustune

Anton: who will win? Mercury: wait it was a contest? Venus: always has been.

Anton: Oh Earth is fine, it’s just a little hot. Everyone: AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

My rule of thumb-more massive always wins, UNLESS the other body is a black hole(black holes cannot break up, all their mass is in the Schzuratchild radius(how do you spell it again?). And if they are BOTH black holes, they eventually merge, due to GENERAL RELATIVITY. I'm so proud of you, Einstein, and wish you were here to see my comment).

When he placed another earth I face palmed

So cool that pretty much all of the planets combined minus Jupiter still get ate up by Jupiter inside the Roche limit.

Anton: earth survived the encounter with Uranus Uranus: not on my watch *gobbles up the earth*

Try to make your own system, using MATH

I don't like maths but watching your vid with you explaining maths is Stupefying

Great video and cool simulation. Can we talk about Jupiter for a bit? Jupiter is a VERY deep gravity well. Deepest in our solar system next to the sun. Acceleration at the top of Jupiter's atmosphere is 24.79 M/s2 (and that's not even on the terrestrial surface to make a like comparison to the earth meaningful.) Your simulation showed that we can combine the matter in virtually all the other planets (gravity wells) in our solar system and still not be as massive nor as dense nor have the magnetoshpere of jupiter. In fact, Jupiter is more than twice as massive as all of the other planets combined... it did not get that way from accreting gasses nor form having a small rocky core... I'm extremely dubious of any model showing the accretion of light gasses into a planet like jupiter without substantial seeding by a lot of very dense matter accounting for the majority of its mass. (for instance you could take all the helium and hydrogen off of jupiter and put it around the earth and it would just blow away... our gravity well, + the additional mass of the gasses would not create a jupiter) It's the depth of Jupiter's gravity well that captures, and retains and all the gasses and makes it the gas giant that it is unlike on earth where hydrogen and helium regularly drift off and escape into space. And Jupiter has enough acceleration to compress these gasses to a density where we get these dazzling bands of fluid dynamics showing across the surface of the atmosphere. As matter stratifies by density in a gravity well, this would put all the heavy, ferrous matter at the core or center and the lighter elements like gasses (albeit compressed) in the atmosphere. Jupiter very likely has a large metallic core not dissimilar to the inner planets with the exception of its size and its core is spinning very fast. (relative to earth) Depending on which cloud band you choose to track on the atmospheric surface of Jupiter it takes about 10 earth hours for one 'day' on jupiter, but the core is spinning faster than this (it's general relativity) creating the truly massive magnetosphere.

I was just playing the game and I made planets orbit each other, this explains a lot

Anton petrov do you have a podcast??? If you don't I suggest you start one. You're very knowledgeable and I know I wouldn't be the only one who would be interested in listening to you on a podcast but either way keep the content coming man. Thank you.

How do you enable the Roche limit? (The particles flying from the planets) it doesn't work for me

The way of earth getting rings in the video just is realsistic

5:19 venus mass: 0.911 earth VENUS DID 9/11

I brought up the Roche limit in science class, everyone said I'm an idiot, but they don't know what a "Roche limit," is.

PLEASE remake Interstellar and how to planets orbit a black hole PLZZZZ

Great video!:]

You should (if you can) do a video showing the difference in size of various galaxies or at least do a video of the smallest galaxy (if anton already did do a video on either of these then i would love if you told me!)

If not sure how much longer are the best way possible

I tried doing the formula to figure out how close the moon needs to be to be torn apart I failed

Yayyyy a video

"Earth wins yaay" Who cares. It is being litteraly torn appart by enormous levels of temperature.

Can you make the planets orbit by size? Also, this includes the Moons, so do as many as you can and rearrange them in order of size.

i made interstellar bodies stars using the roche limit

awesome

Jupiter, king of the planets, and destroyer of comets

This would be so awesome once Universe Sandbox has SPH Fluid Simulation. :)

"it just ate the whole venus," Glad it wasn't Uranus!

How long does it take for them to tidally lock at this distance? Is there a mathematical formula to determine this?

Could you heat a gas giant by a binary system by the Roche limit and put earth in the habitual zone of this hot gas giant system. Basically a neverending heat from tides heating

nice video

2:17 why does mercury look like the death star???

Anton I'm new to Space Engine and I enabled Grid mode somehow....How do I disable it again?

awesome thanks

Its plausable Earth size exoplanet sustain life without star, but tidaly heated by small but extremely dense moon ? How masive must be that smaller satelit ? How near must by to heating enaught but not break apart ?

So if planet X is orbiting jupiter up through the solar plane at an angle what is its distsnce from jupiter, period, and effect on earth?

Interesting observation at the end, objects in orbit if colliding with earth would tend to hit equatorial areas. But our observation is just the opposite, them hitting more polar areas, such as Siberia & Canada. Why?

Earth got absorbed by Uranus.... LOL.

can you make a video about wr-104? on universesandbox...

This is why I love physics

0:30 welcome to what da earth

plz make a video of earth and Saturn in roche limit

My theory : gravity also plays a role because it make planet's masses stick to them so with more gravity you get to survive long and you can rip other planets faster

Make a video on every black hole merging

3:54 looks like Earth from bo2 zombies?! Are we going to Venus?

I see that tidal heating bug is still there:E

🎼I'm your Venus, you're my fire, skeet inside her. 🎶

Roch limet is now called masrateropithus now or mas for short

I want the link to old version tablet

WOW COOL!!:)

Merge Pluto, Mars, and mercury. Then time lapse ahead 1a millions years. How similar to earth is it if in the Goldilocks zone?

this guys voice is 🔥

what is the largest a star can be?

For the first few minutes you figured out how the earth and moon was formed, along with the asteroid belt.

How did you download tha app

if you do this combining of all the planets (mercury through neptune, plus planet 9 aka X), you end up with the giant planet having a mass of 1.32 jupiter's

I was looking for Kirby music remixes and I ended up here instead

Mercury is made of iron (mostly), so I don't think that Venus would win. You would need a lot more force than you could have in that scenario to rip metal apart.

I have heard that saturn has a satellite which has ice on the surface but under the ice it could be liquid water. The reason for this is the tilde force. Could you place 2 earths so they can rotate around each other and through the tilde force on the planet both would have liquid water?

You Breaking the game in the time 12:09

what happend to saturn in her roche limit

Any rom-com screenplay writers? Here's your title: Roche Limit. "Two astrophysicists test each other's gravity. Or will they crash and burn?" Or whatever. Maybe 'on a starship.' Oh, the possibilities! [It better be good.] (Can Anton act?)

Here is an explnation:the more massive objects gravity crushes the less massive one cause think about a marble if you crushb it, it breaks but why?cause you have more mass and the crushing it it also applies to gravity

10:57 saturn just changing axis every 2 hours

Hello wonderful person 0:00

Can a blackhole lose tho, like if a very small blackhole approached huge neutron star, does the star have any chances at all?

1:27 THE BIG FRAGMENT HAS WATER + it looks like earth and moon forming ngl

I don't feel so good mr anton

What if 2 Roche limits meet?

13:09 Seth at earth is burning away

Lol 13:26 show moon's moon,which is moon

"earth seems perfectly fine" 11:55

I also have universe sandbox 2 but aphla 15.1

0:45 look closely in the left and look up I see a planet that just formed 2:12when Mercury Dies and Venus wins they make more planets which kind of look like Pluto mini Pluto's

Uranus has a lower mass than earth but if the earth was near it, it would create a binary planet system, the earth is a lot denser than Uranus.

I Can A Question,Uranus is Thirth Coldest Planet in Universe?

When Venus dies I laughed so hard

13:07 you re-created the Jupiter system

Doesn’t Jupiter have more mass than all planets combined?

watching that intro made me wonder. what if thats how our moon was created. maybe earth (of smaller mass) and another similar mass had collided. the smaller mass in the intro resembled our moon with size and orbit.

Cool i want more crashing videos And earth won yay

what version ya usin

Can a habitable planet form from two close by planets? Imao kinda worded badly, it hard to form a decent sounding question

Yes but what made one of 2 identical eaths break apart instead of the other.

You should combine all drawf planets

I want to play this game

5:19

Collide all the Planets using the Rosche limit and then Terraform it
