- Astronomers have a hard time communicating the scale of the universe, with objects being so far away it's common to bring things down to Earth to make it easier for the general public to grasp.
It's a lot easier to imaging the size of a space rock if you compare it to a city, or a white dwarf compared to the Earth or sun.
I imagine the consequences if these objects were really moved this close together.
Universe Sandbox 2 lets me simulate some of these with glorious graphical destruction.

Not even "just for scale" size comparisons are safe from Scott's critical mind
i think his point was that they're NOT to scale
@@UnderscoreZeroLP But the sizes are to scale. It's just that the distances involved when showing this size comparison would have dire consequences if replicated.
no matter how hungry, or how cute they look: do not feed the white dwarf.
And never get them wet?
And certainly not after midnight.
When are we going to call one Gizmo?
Yes, do not feed the white dwarf. Except, that is, to a black hole...
Fred
the first time i saw a white dwarf in ed i thought I was going to feed my FSD....I got torn asunder.
I'm impressed that universe sandbox has all that programmed in.
I'm more impressed in how they actually managed to program it. Did they program all the possible interaction of two body types they could think of, or are they actually using planet composition to determine the most likely physical-chemical reaction that will trigger. That added to some kind of fragmentation algorithm based on density properties or something.
But object transitions have to be hand coded for sure.
I don't know the programm, but I think it's just does the math. (In a very low resolution and at some point it just guesses)
In the end they display it in an predefined way.
@@Codiac300 Yeah, but it's a lot to add into your physics model to actually check the densities and material properties of the two objects to see if either of them will break up. I'm pretty sure the equations for that are quite complicated. Especially since they seem to be accounting for the rate of breakup as well, although I'm sure the graphics are just sorta standardized rather than being exactly simulated which bits will break off.
That's like graduate level physics in a video game.
User Acceptance Testing must have been great fun - let's see how we can break the universe!
It's not «programmed» in the program. The program only apply gravitational, and relativistic, formulas to objects. It does contain the information about many known objects, but unless those are placed in the vicinity of another, they'll only sit there doing nothing.
"Sure, it might fry the Earth with ultraviolet... but there's a scarier thing that happens!"
Pray the Q continuum will NEVER SEE THIS VIDEO.
They're still rewatching Voyager, they're a bit narcissistic
Just change the universal gravitational constant, problem solved.
@@thefacelessmen2101 HAHHAHA. Watched that episode 2h ago
Eh. What Q causes, Q can reverse.
For that matter, I wouldn't put it past him to put an asteroid near a city and just...
Turn off the laws of physics, for lack of a better way of putting it.
I mean, if you can arbitrarily move astronomical bodies around, you can likely violate most of physics anyway.
So... You know. Consequences? What consequences? XD
They already did it 8 times. Then gave Scott the idea for the video. ;)
*“The greatest shortcoming of the human race is our inability to understand the exponential function"*
~Al Bartlett
AI as ai Bartlett ? I guess he would then... (BTW covid virus made many people more aware of the exponential function.)
It's a cone with concave sides.
"Fly safe" has never sounded so ominous.
The thought of the earth touching against a "tiny" 10km blue ball and instantly being consumed is pretty intense. Would like to see it in person!
It'd be a precarious situation for your eyes tho.
I'm sure you would not
I would not
@@Mandrak789 Not even close.
I wouldn't!
HE SAVED EVERY ONE OF US!

WHERE WAS HE WHEN THE WORLD KEPT ENDING?
ah, yes the most known of all measurements 1 Darmstadt
Never measure in Bielefelds though. That breaks the universe.
That's were the European Space Operations Centre (ESOC) of ESA sits. ;)
After Googling...
Surprised I am that I have before not of Bielefeld heard.
I prefer milidarmstadts to regular Darmstadts.
Neptune: "Welcome to the Solar Spitoon, how tough are ya?"
Jupiter: "I ate a bowl of Earth for breakfast this morning"
"Yeah, so?"
"... without any Milky Way"
References (*_,* )
Oh damn Jupiter, you scary!
"Uh, right this way. Sorry to keep you waiting."
I've never understood why a Mars bar is so much larger than an entire Milky Way.
The best jokes and jokesters (not jokers) are here on Scott's channel.
Funny takes intelligence.
*As an omnipotent deity, I disapprove of you trying to ruin my fun.*
Have you been smoking something interesting oh all knowing one? ps. can i have some?
You're confusing me with an omniscient deity. Beth, you fool.
@@YIIMM I apologize please don't smite me D:
As another omnipotent deity, I think you should probably just ignore Mr Manley.
We can do what we like without consequence. Laws of physics and such are meaningless.
That's what it means to be omnipotent doesn't it?
If I wanna put earth in an orbit around saturn and have it survive unharmed, a trivial matter like physics isn't going to stop me...
And if I don't care if it's harmed, well, sucks for you, earthlings. ;p
@@KuraIthys Tell me oh...erm powerful ones... Is it worse to be a stupid destroyer of worlds, or an all knowing deity armed with a wifflestick?
I represent all virtual sentient races of current and future Terra, and I advise you to stop feeding Earths to enormous stellar entities in the future.
Indeed. If you keep feeding astral bodies Earth, they may learn to associate humans with food, and wander into our stellar neighbourhood and attack people or cause property damage. Best to leave celestial objects alone and let them forage for themselves in the galactic wilds.
So tiny stellar entities are still fair game? Great, 'cause I got a few neutron stars and they're looking a bit peckish...
I like how you use "masses" instead of "weighs" to indicate measurement of mass. I need to start using that terminology too!
Scott your video titles have been off the chain recently. Keep up the good work, and fly safe.
I love this channel so much, thank you very much Scott for putting things in perspective!
This is one of your best videos yet! Thank you for your research. Fantastic!
What a creative idea for a video!! This one really stands out for that, as well as its quality. Thanks for sharing such fun things to learn and think about, Scott.
EDIT: Some annoying circumstance is preventing me from calculating this, but does anyone know the minimum distance the moon could orbit without tidal disruption and how large it would appear to us on the surface? I'm a wee bit drunk and lacking some resources I'd need. Thanks!
This is easily one of the most entertaining (while still educational) videos you've ever done. Well done good sir!
NO Scot the quote is
"Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space."
GET it right next time
But the real question is, how many roads must a man walk down?
@@omermagen824 And who's shoe's should he be walking down it in?
@Troll Trollsen Drink 3 pints of beer...muscle relaxant, you'll need it.
@Troll Trollsen And only 3 pints of beer.
foop!
As Brass Eye would quote, 'This is the one thing we didn't want to happen'. Well done again, Space Scientists. Well. Done.
Universe Sandbox is amazing.
more of these please . very exciting to watch. thank you by the way
New Scott Manley video makes me so happy. None of the other people making CZcams videos make me feel like that!
Great video Scott! Great content and so much references!
8:00
"the temperatures and pressures have not been sufficient to fuse all the way to Iron."
Wait I see where this is going. Oh god it's going to go supernova.
Excellent and informative video. Absolutely fascinating Scott.
8 seconds in and I’ve already learned something new! Thanks Scott!
I thoroughly enjoyed this video! Thanks Scott!
I've seen several comments (for obvious reasons) concerning Q and his abilities relevant to this video.
I picked one and replied to it, but my reply became long enough I felt it may be worth posting generally.
The original question was essentially "If Q can do all this, why is he interested in our intrepid voyagers?"
My reply is below:
Well, to be honest, he's interested in it because we're human, but that's kind of meta and anthropocentric. In a more in-universe sense, Q could easily do exactly what we're seeing here: play Universe Sandbox for real but then roll back time such that things are as they were. We would never know he did, because we don't have the senses to notice it. The thing is, even though each instance of destruction would be somewhat unique, just as each fireworks display is unique, the detonation of fireworks is understood by a pyrotechnician. Q would know what would happen to inanimate matter because he knows what will happen when it is exposed to certain conditions. I mean, WE know what happens to it well enough to make a game of it, and we're hardly omniscient.
However, animate matter is different. If you expose, say, a human to the conditions of the surface of the sun, the outcome is entirely predictable. However, within easily understandable physical limits, our outcomes are much less predictable.
Assume a purely physical model of humanity, Q could easily see the map of a person's nervous system, know what they are capable of thinking, and still be left in the dark about what they're actually considering at any given time.
The Enterprise is the flagship and must then be crewed by person's with exemplary minds. The more connections a mind has, the more unpredictable (read: interesting) the human outcome will be.
Thus people are more interesting than supernovas and Sociology and Psychology are the highest and most difficult of the sciences.
Always love your video's. Thank you Scott!
Great vid, man. You make this stuff fun.
Super awesome!
I can’t wait for the next Cosmos! This is just what I needed. 😁
This made my day! Thanks, Scott!
Scott, I genuinely enjoy your intellect. Carry on.
Not sure why I only just subbed to this channel today.
The crash of Moon onto Earth is a perfect illustration to excellent book Seveneves by Neal Stephenson. It was like I'm re-reading it in 30s or less.
In the novel the moon was in its actual position tho. Chunks of it started falling towards Earth because their mutual attraction eventually accelerated them into abandoning their original orbit. I think they call it the dance in the book?
@@DamianReloaded Yes, the initial scenario was different, but once the Moon got all broken into small chunks that was it.
I started reading Sevenves the day it was published but didn’t get very far (it didn’t grab me they way Zodiac or Snow Crash grabbed me) and I kinda forgot to go back to it. Thanks for the reminder, hopefully I can get into it on the second try (which is what happened when I read Diamond Age; first try I gave up but after I went back for a second attempt I loved it)
Good video! Nice to actually "see" all the things I've been taught in Astronomy class this semester! (Also, explosions)
I love the concept for this video. Great job.
to make things simpler, I measure time in parsecs
LOL nice one mate :P
Lucasburn!
so around 3.26 years?
The Kessel Run was measured in distance, not time.
What an amazing video! Thanks Scott :)
More of these please that was very cool
A great video that answers questions that have popped into my head whilst watching those kind of clips - but in so much detail and with most excellent references. All this from an ELITE nut - I have no choice, +1 subscription.
We need more of these videos Scott Manley!
Despite my knowing that these things will not happen anytime soon, it's still a bit terrifying to see such enormous power. As for Q, I think he's cool with humans thanks to Picard, but his fellow Continuum member Trelane, the Squire of Gothos, may be the bigger threat.
I found this Fascinating
Thank's Dr. Manley!!!!
hahahaha Scott, you are getting so creative with the subjects of your videos. 4 years later, still don't miss any of them! :D
Nice star trek reference at the end. Love your videos keep coming.
Ok, I need Universe Sandbox 2 in my life!
Just saw your presentation at Chabot, it was great! I think I may have to pickup this program. Keep doing what you do and Fly Safe o7
you know, sometimes I dont even pay attention to your videos, I just relax and listen to the amazing voice.
OOH You should try reading audio-books or something, that would be amazing! with your knowledge and reputation as an astronomer as well as the brilliant voice you would be perfect!
this is actually one of your best videos. really interesting. !n
I really enjoyed this one! Thank you.
This was awesome! More
! ☺
When I come on CZcams and see you've posted a new video, it's the first thing I click.
Scott has to be one of my favorite channels on CZcams right now, close second is CuriousMarc with his Apollo Guidance Computer restoration videos
This was hilarious and informative. Thank you.
One of your funniest videos this. Had a good laugh. Thanks. :-D
I also watch a gaming channel called GrayStillPlays. Ironically, he does all of this as well, but his focus is on suffering and loss of life with hillarious commentary. I am so happy right now. I feel like I've come full circle.
awesome vid, best in 2019 so far
One of my favorites so far
Lol I love these type of videos. Keep me coming!
Great fun Scott!
I was helping my elderly mother dye her hair, and I tease her that she looks like Ming the Merciless during the process. This video was on TV and no sooner than I had said it so did you. I love it when that happens. 😀
Great content and presentation!
Love it. Learned a thing or two about world annihilation
great video, more of these type vids please!
Amazingly good idea for a video
This is really dark humour. I'm glad Scott has a BENIGN creative outlet. Lucky for us all!
This was pretty fun to watch
Hahaha, so cool!!! Its amazing that Universe Sandbox can actually run these simulations.
Brilliant and very funny - great work!
Love Q. All time favorite character.
9:39 I am living somewhere in this image. Greetings from Montreal
Fun isn’t something one considers when balancing the universe. But this… does put a smile on my face.
The dry humor is killing me! Nice video!
super interesting stuff!
Scott Manley shows how can we destroy our solar system and Earth, says do not do this, and says fly safe..... That is why I love this channel
This dark energy & you wanting to get your doctorate, perfect topic for your Thesis.
Great video!
I'm just here to say how much I love that title.
Thanks Mr Godlike Super Being
I loved the commentary
Amazing video
Lol, that reference to “Q”! I was not prepared for it :D
Cool new track at the end
This is a pretty good demonstration of the Roche limit
I like to play with things a while... before an annihilation
This is the strangest video title you have ever used...
And tng reference is awesome. Good ol Q. One of my favorite characters.
I wonder how many science teachers announce to their class “For today’s lesson, we will be discussing this Scott Manley video”.
Scott would stop give Supervillain Ideas!!! awesome video :)
Good video, thanks Scott. When I see Venus high in the sky I sometimes think that someday the sun will expand to the size of Venus' orbit so where you see Venus it will be the edge of the sun. I gotta get universe sandbox and try that out.
I love space engine. Love that you used it.
universe sandbox is also cool
Gotta love that dry humor cultivated by our friends from across the pond!
AWESOME SIMS!
Excellent.... very much like an animated XKCD "What If"
"Imagine you are some godlike superbeing"- like everyone that's ever played sims.
Started watching this thinking "oh Scott, have we been playing with universal sandbox again?"..
I once read a book about some Moon Earth conflict and they threw rocks from Moon to Earth. And people went to watch the rock landing. Seems something that people would really do. Would not if they had seen this kind of videos. Keep educating, it's both fun and, well, educating.
Didn't Brianna Wu when she was a Democratic candidate for Congress, claim private space companies could be dangerous since they would have the power to destroy the Earth with rocks sent from the Moon.
One of the funnier of your videos. Thanks for the laughs.
Try to leave the earth in one piece, Bond.
Oh, not that Q?
