Using a black hole to create supernovae | Universe Sandbox ²

I explore tidal forces and what happens when the moon in within the Roche limit. The sun can also be destroyed by tidal forces from a black hole, and larger stars can apparently create supernovae.

There's something both relaxing and mildly disturbing about watching someone casually destroy the Sun and Moon with a smile while explaining tidal forces. I love it.

[@francosanson9623]

Timothy Warner she talks in such a relaxed way that it's like you see your planet being destroyed and say "huh, what a pity"

[@AndrewCheetah]

I came, I watched, I learned, I relaxed, I liked

[@nox2sweet]

3:15 "The Earth is moving *very slightly* further away from the Earth" me with astrophysics in a nutshell lol

[@MrKillshot2]

She's basically the human version of mother nature

[@tedled4710]

All the dislikes are from, flat earthers

[@Joshua-dc1bs]

The Earth doesn't exist.

[@TheLeontheking]

really relaxing to see that stellar destruction to that pieceful music ;)

[@juanpaVlz]

Your eyes reflects inmense love and compassion, that's something inmensely beautiful and priceless, never change. if you change, the world will lose a beautiful human being

[@abedfadila9266]

my kind of gameplay video :)

[@JayFolipurba]

this was incredibly relaxing with the music and your soothing voice. You're a great explainer and seem like a very friendly person. keep it up

[@hikaroto2791]

you look so happy and exited when talking about the masses ripping apart and heating up and destroying by tidal forces, i find it cool too

[@bpdlr]

This was amazing. Taught me a) that supernovas probably don't ever explode from a central point scattering the debris in a sphere (as I always imagined) and b) how the elements created in supernovas can escape a black hole's gravity.

[@Aycore2011]

Man, is it just me or is Astrophysics very depressing, like for real what If we are really alone out there. *single tear rolls down*

[@supersmashsam]

Look at you, casually sending moon fragments towards the Earth without remorse! I shall call you Tibees, the celestial destroyer :p

[@stewarthills9344]

supersmashsam it’s a simulation, I hope...

[@eidechsebernstein954]

Ohhh how I love these videos! I hope you will do more

[@Kanal7Indonesia]

People like you make me believe in humanity again. :)

[@francosanson9623]

Your voice is quite relaxing.

[@AJGabbo]

The music background and she explaning physic give chills, Im learning more thst I did in high school.

[@anonyme103]

Please do more ^^ you're so adorable and watching you is so relaxing and informative

[@RAyLV17]

Instantly subscribed! Really nice video!

[@chinesecabbagefarmer]

I am interested in the things you say and enjoy to hear them. I respect the things I enjoy learning. You represent all of the things I like. Despite how it may feel we are floating alone on a rock I think we are floating together on a Universe

[@proyecthaarp]

your voice is so relaxing

[@AGriffith]

I love the music and the video, it is too relaxing and interesting

[@MrEgealp]

I've just found your channel with that video and ı love it! Such a brilliant fun

[@oliviapeyru4677]

your videos are both relaxing and educational.

[@brundhaaa]

I’m in love with the software 👌🏻🔥

[@Otonium]

Love the music, makes the video mesmerizing.

[@guiwald]

- What do you do during your free time? - I obliterate stars to create supernovaes

[@edexnorth123]

Congrats! You've just smiled 100x my monthly rate in just one bloody session.

[@gregoryhristov]

You are crazy devoted and I admire that concentration. I am a bit jealous and I must admit l wish to be like you in that respect. Teach me, please 👍

[@1.8.7laikuza6]

This is amazing!!!

[@xDiilllToullllliiiDx]

I just meet your channel this is so good!

[@beretperson]

The closer to the Earth, the more stress...no wonder we have anxiety.

[@Dangmaar]

I love your channel and your videos.. i made a lot of mathematics and physics like analytics, algebre, flow thoery, quantum mechanics and some exam you had, i had too. You feel so appease when you talk... :)

[@honeymartin9120]

Great videos. Thanks so much.

[@garofiespinoza3503]

this is so relaxing

[@falsfire]

Not sure if this comment will be seen on a video almost two years old, but I'm new to the channel. I've watched a number of your videos and just wanted to say that they're informative, and very relaxing to listen to as you have a very pleasant voice and demeanour :)

[@Trip4man]

Cool simulator. In my opinion, you were correct calling it a Nebula - a Supernova is when a star explodes from within and not by external forces. I think that removes the possibility for the formation of a black hole also... Because it wasn't the core that collapsed but rather the violent strip of gas that occurred. But what do I know, I'm just an astronomy enthusiast... Greetings from Portugal :)

[@jpmcb1394]

love the video, make more they are super relaxing. also american "where" @ 1:25

[@03335757975]

i loved it. Any more stuff on black holes please ?

[@pappi8338]

Great video! That would be cool if you investigated with multiple star systems and worked with their barycenter!

[@tibees]

Great suggestion thanks!

[@rorywhyte6722]

This is extremely cool!

[@martiny1785]

love these videos

[@tibees]

Thanks for the comment, I'll have a look for planetary nebulas next time I play. I am still a PhD student, I only started in August 2017!

[@martiny1785]

which you the best with it... i have 5 more years and i'll go for a bachelor .. damn... time's passing slowly.. maybe it's something to do with the speed im traveling relative to the others .. jokes aside ... I wish you success with your PhD

[@CandidDate]

How does gravity work? I assume this program uses F= G*m1*m2/r^2? But when you have more than two masses, what formula does one use? I'm thinking along the lines of each atom has a gravity vector. If you sum all the vectors of earth pulling on moon, do you get a big vector, or what? I have a hard time understanding this concept. And does not the moon pull on the earth in equal and opposite proportions?

[@matthewbilik9549]

CandidDate, you would not use more than two masses as the force of gravity can only be measured between two objects at one time. You could also use Fg=mg to find the gravity between two objects. Correct me if I am wrong, I’m a High School Physics student.

[@jackgriffiths3861]

3:16 lol the earth is moving further away from the earth :)))

[@tibees]

Omg so embarrassing 😂😅 I never noticed that before

[@jackgriffiths3861]

lol, its not that embarassing, it was quite funny :)

[@puffballavada6967]

Wait didn't you know that the earth people are trying to overthrow our government by moving the earth away from itself? This is also known as the climate change hoax.

[@MikaelIsaksson]

When I was a kid, I played this lovely game named Sim Earth. It was simpler times back then, so although the simulation was very crude the curiosity is the same.

[@alanhembra2565]

You have a very calming timbre to your voice.

[@adflicto1]

That was really cool

[@lobsk]

Oh. This looks like such a fun simulator to play around in! Any flaws that you have found in the simulations themselves?

[@philwesom8784]

wow...so nice

[@theholisticdog3381]

This is like ASMR almost

[@lucaslopesf]

Fascinating

[@blackdogultra]

Good stuff!!!

[@cedric2803]

I like this video! :)

[@bingjie888]

Tibees"the mother of supernova, moon killer and sun breaker"

[@EG-cs3wv]

Your voice is so relaxing

[@Tinybabyfishy]

Tibees, what determines the angle at which the "plumes" of matter are ejected from disintegrating satellites within the Roche limit? I was trying to eyeball it but didn't have much luck. It's clearly not ejected along the line tangent to the orbit, it seems to be "pulled" slightly towards the CoG. I also noticed that matter is being ejected from two points - opposite one another along an axis through the centre of the satellite. Why do we get this effect? (This is quite an old video now, I know, but hopefully you'll see this!)

[@abalint8097]

omg - this is soooo cool!!!!!!!

[@tibees]

Thanks!

[@Bertydude]

You are a nice human specimen

[@abhijithcpreej]

That music! Please tell me what you used! So relaxing

[@bencarter5563]

This reminds of Minecraft, maybe just because of the music. BTW I would 100% watch you play Minecraft.

[@GeorgeArellano]

Fun to watch, given she plays god. Thank you, this fascinating to watch. :)

[@Henrikko123]

Physics ASMR

[@MrJ-ro1yr]

I listen to her as i fall asleep. Her voice is very soothing to me.

[@ewthmatth]

0:34 ... The moon exerts tidal forces on the earth too. Our ocean tides come mostly from the moon.

[@AsmrPlaylists1]

This could be a series lol

[@iiimusika]

ooh excellent,,,,,,

[@hondo190]

How did yo get the trails to be reflected in the black hole? This effect looks pretty cool. I only can see the stars but not the trails.

[@samyuen8234]

according Newton's 3rd law. the earth exerts the gravitational force on the moon and the moon also exert the same amount of force to the earth. so that's can explain why during at night got high tide is because this part surface is closer to the moon than the other part of the earth

[@hirokatsuvictor8755]

I live how they updated the physics, last time I checked it only had the moon just casually getting closer and then it gets devoured by the Earth

[@tibees]

They have lots of updates, in my latest sandbox vid I showed the Tesla Roadster update

[@User-kt7kj]

Thank you Bernadette

[@izarscharf7845]

I clicked on this video simply to comment this: Thank you for using the correct latin plural for a latin word "Supernovae" for the win

[@edwardtcrump5312]

Sagittarius A* is OUR black hole. It's at the center of the Milkyway galaxy, and is therefore a supermassive black hole :)

[@peterbonnema8913]

Recommending people to explode stars with blackholes at home. Usually these things are accompanied by warnings like 'do not try at home'.

[@Taricus]

6:05 Saggitarius A* is the supermassive black hole at the center of our galaxy :P

[@TEROR3000]

Beautiful smile ☺

[@ck88777]

Have you heard of Space Engine? it's a procedurally generated universe simulation that allows you to fly around and explore our galaxy, generated stellar bodies/systems and celestial systems/bodies. Also, it's free and open source.

[@KPpivot]

I want this game

[@joseVMex89]

Is there any way I can download this without having to purchase it Miss Tibees?

[@pratikpatoa7724]

What software is that?

[@tygertyger8597]

Wow, Tibees just came right out of the Bhagavad Gita and became THE DESTROYER OF WORLDS!!! She did it with only two arms. 💪💪 😂

[@antonykalluveettil4764]

On heating up which energy decreases?(thinking about conservation of energy)

[@undertheradar4645]

At a certain point it almost looked as if a ring was forming around the black hole.

[@liamwilson12345]

It makes sense because light is being swallowed from the star that could cause a smaller black hole

[@satviksoni6764]

You can change the units of mass by clicking on them! :)

[@rambojohn9041]

You should start modding the game and putting some rockets and spaceships destroying earth and creating massive electromagnetic fields etc😊

[@0r4ng3p33l]

Do you do this regularly?

[@souravdalapati.6270]

How will you explain tidal force in case of Einstein's theory of gravity?

[@OurDailyMeme]

Only 17k subs? 👀

[@MarioRugeles]

Hi. I got a question. Why the supernovas start to get away from the black hole? Regards.

[@Assabinnas]

Is the music part of the software or did you pick it out? I love it.

[@tibees]

This is the in-game music

[@sreejithaj5024]

To shreds you say..

[@Thetouristyour]

What program is this?

[@publicstaticvoid3224]

RIP Mr S. Hawking, one of the most brilliant minds of our time Pi day 2018

[@rambojohn9041]

oooooo nooo fuck the oceans are getting really hot. lol

[@nalexandi]

Amazing, what software is it and where can i download ?

[@tibees]

This is a game called Universe Sandbox 2, I downloaded it on Steam but it costs money to buy, about $25

[@AGriffith]

Hey, what are the spesifications of your computer? I want to study astrophisics, and I want to know how good my pc needs to be

[@tibees]

I have an old Macbook Pro (2012), you dont need a good pc to study astrophysics in undergrad as you will mostly just be doing problems on paper. A good pc or mac will be useful when doing research projects but in my experience you will be given a machine to use if you are working for a uni

[@abhishekchauhan6092]

Which application are u using

[@CosmosBFN]

one question ma'am... what's the way to Jupiter 😁 and why are we being created

[@luis-sy3ci]

Hello, do you know if it is true that in the northern and southern hemispheres there is a hole in the interior of the earth? :D

[@JLPC13]

'Welcome back to the Universe'..... Where the hell was I?

[@mc4444]

I think the supernovae happened because the massive stars collided with the suns that were already there. It's funny how they just disappear into a puff while you would expect the opposite but I guess a white screen wouldn't be that interesting. Simulating star collisions is not easy and I think that the supernovae sometimes expand faster than light so the game isn't 100% accurate but it's still fun to watch. One thing that can be done in the game is squishing the star by, I think, decreasing its volume until it turns into a black hole. I would be funny to see the solar system where the sun and all the planets and moons were turned into black holes (though everything would just be black). You can also shoot hydrogen at stuff and turn random objects into stars ;D

[@tibees]

I wondered if that's what was causing the supernovae, but anyway I found a scientific article saying that tidal forces from a black hole can reignite fusion and lead to a supernovae, here's the link www.sciencedaily.com/releases/2008/01/080129125350.htm

[@mc4444]

Wow, that's really cool. I never thought about that before you mentioned it in the video. Just another interesting thing tidal forces can do.
