Illustris Simulation: Most detailed simulation of our Universe

[@gregoryjacobs5833]

Very proud of my son-in-law, Greg Snyder, collaborator on this project.

[@creamsykle]

How many civilizations did they destroy when the simulation ended?

Thanks for the existential crisis!

[@CyPorter]

Great to see what people can do with super computers.

[@jorgbeijer]

I hope that was sarcastic

[@Eddiedb451]

jorgbeijer Why would that be sarcastic? You clearly don't understand the power required to simulate something like this.

[@jorgbeijer]

No I'm fairly certain that my understanding of that is sufficient. But if that comment was sarcastic, it was funny. If it wasn't, I dare ask what is so 'great' about a simulation that will be outdated extremely fast and in my opinion is a complete waste of very valuable resources (time of brilliant minds, endless consumed hours of our best computers and a truckload of money) that could've been spend wiser.

[@alexfrance]

jorgbeijer You have to start somewhere. We didn't just stumble across quarks and leptons, scientists theorised about an atom. Those theories were then revised many times over a long period to finish at where we are now. In 10/15 years time we will look back and have probably found out something that will rewrite all current knowledge about particles. You have to lay the groundwork first and that is what these scientists have done with this simulation.

[@waynemartin1490]

jorgbeijer How incredibly shallow! To compare observations with simulations is to understand the world around us... Be grateful that we are able to push these boundaries as you wouldn't even be able to express yourself via a computer... Hence this exactly how you are able too! Although I guess you would probably be good with just pretending you were typing your thoughts into a Rock...

Watching this, you start to feel the scale of the drama :) Also, would be very interesting to extrapolate the simulation further, up to subseconds after BB, to the earliest moments for which we have data. And inflation... with the very space expanding faster than light... would be awesome to watch! :D

Awesome simulation. The part from 2:50 amazes me, too. Realy shows off how unimaginable big the whole universum is and what coincidences have been around in order to create us, a species able to question those coincidences, question themselves. What freaks of nature in this vast universe IF we were the only one.

[@TimDalinianJones]

Thanks soooo much, you folks - this presentation puts a Massive Smile of Cosmic Connectedness on my face. This Illustris Simulation was just reported (inc. video clips) on the 18:00 BBC One TV News in the UK (Wed 07 May 2014), which led me to the MIT news report, and thence to here. We are indeed an instance of our cosmos becoming self-aware of its own history and functioning, and you people are at the very heart of our ever more detailed and precise cosmological explorations - love on ya, sisters and brothers!

Same here. although boinc generally averages about 240.000 volunteers. I have seen the stats say over a million computers occasionally. I don't know how big the universe is? 65 billion light years? a rough number I think I heard on a youtube lecture? surely we could attempt a full simulation or a pretty good one.

[@marcokavinsky4226]

I think we can really be inside a luminous cube just like this illustration and that this same cube is hanging over the cradle of some baby, son of some divine being, just for him to play and have fun and not be afraid of the dark in his heavenly bedroom, before bed. This cube is a gift given by his father on the day of his birth. Once the baby has grown up, he will still play with his cube, sometimes more, sometimes less. There will be times when he will leave the cube aside, half forgotten. Then, a few billion years from now, the divine baby, now an adult, will pass on his toy, a kind of family heirloom, to his own son.

Re: Life: Perhaps it is not "how far one can go" that matters, but how far one can go and still find their way back to the simple joy, pleasures and wonders of their youth.

[@DjLemonic]

In theory, if we would be able to simulate every single law of physics in one giant simulation, and let it run past our time, wouldn't we see life forming and inevitably get a glimpse of future that way? I think it would be awesome to fast forward the simulation until the simulated life created their own space ships and stuff like that so then we can take a look at what its made of and make one of our own :)

[@Ultrox007]

...Your move creationists...

[@Janitorus]

But there's this book...

[@keylanoslokj1806]

and why are you so desperate to disprove something you dont believe into? why to use science as a justification to cover your fears and existential insecurities and denials? where you see disproval others see and admire the wisdom of God. whose approach is the problematic one will be quite possibly revealed at the moment of our inevitable death. till then try to focus on the pursue of truth and contributing to humanity than surfing for fun to occasionally disproof (in your mind) a concept that was created also in your mind in the first place. cause God is Revealed through participation in christian spirituality not proven in any cerebral way. a provable God would be too little any way...

[@Janitorus]

Lots of assumptions there, well done. Science is a way of figuring out how reality works. If something has an effect on reality, whether this is gravity or god, science is a way of finding out how this works. It has nothing to do with fear or desperately trying to prove a negative. It's about valuing what's real and what isn't. Something which, after reading your last sentence, I really don't think you care about.

[@keylanoslokj1806]

Trinitrotolaissance science merely examines the creations of God but cannot say anything about the creator. to put it simply God is so ethereal and spiritual that it is impossible to measure Him by any scientific method. He doesnt want to push the faith on anyone he wants us to believe Him with free will. thats what faith is about in the first place. He can only be revealed to the person not discovered by it. he works in utmost subtlety and mystery. a God conceivable mentally by the human mind would indeed be too little. its only meaningless pride by us to think we can "conquer" God with our mental constructs. How God is revealed? we know it from the scriptures. its a fashion today for some atheists to make fun and degrade the scriptures and satan is dancing with joy for that. cause the bible is indeed the word of God and all the existantial answers are there. like with a human, the relationship with God should be a personal one. in the new testament He gave us his new law(s) which is actually one, love your God with all your heart, power, and mind. and love your fellow human like yourself. and now how do you show your love to God? by keeping my laws as He says in the scriptures. participating in the mysteries of church, fasting, praying etc. and of course with showing love and care for our fellow human. we know from the revelation that in the final judgement he will seperate the righteous from the sinful and will say to the first. i was sick and you aid me, i was a stranger and you took care of me, i was imprisoned and you visited me, i was poor and you fed me. and they will say when did we do that lord? since you did that to your fellow people its like you did that to me. and to unrepented sinners he will say. i was ....(all these) and you didnt help me. and they'll say when did we ever see you and didnt help you lord. since you didnt do it for your fellow humans you didnt do it for me. thats how you create a living relationship with God. and you open to Him and He opens to you. thats how you become his son and he reveals himself to you and you commune of his holy grace, and your spiritual eyes open to a new world. where we know all that from? from the scriptures and the experience of the church fathers and saints. and since all this knowledge is available and acessible to the western world. noone of us will have an excuse of not knowing, cause everything we needed was in our hands.

[@Janitorus]

An all-powerful and all-knowing being gives us rules, only to have them changed later because apparently they didn't work out? A loving god who decides to drown 99.9% of his creation, because they didn't stick to his rules (which he knew beforehand). Yes, drowning equals love. Mind you, innocent babies were also drowned. No, please don't get me started about how loving your god is. Every time something good happens, it's claimed to be the work of god. But when a five your old dies from cancer, we are led to believe that god is mysterious. What a fucking joke. Bottom line is, if your god has an effect on this world, it can be measured. And thus it becomes scientific. Hearsay and accounts from priests are what they are: stories. Just like the bible. Plus I do not think we need a book or a god to tell us that loving one another is important. And lets ignore for a second all the nasty stuff that's in the bible, because that really doesn't help your point of a loving god. It's also funny how your god is so mysterious, ungraspable, ethereal and what not but yet you, a simple human being, know what he wants and does from the means of scripture (which, by the way, you know to be true how exactly?). I'm also not impressed by this satan story. If god is indeed all-powerful, that means he is infinitely more powerful than satan. And thus should be able to get rid of him easily. Apparently he didn't. Tell me, are there any other areas in life where you value hearsay more than actual evidence, or is this just limited to religion?

[@pyrix]

Yes, it IS just chance, because look at all of the other planets that are out there with zero life. Guess "god" made those just for us too? You're a fucking idiot.

[@keylanoslokj1806]

pyrix if you knew the impossibility of all these around us to happen on chance you would not use these names for other people. not to mention the human being. from nothing to have humans on earth by the mere formation of some proto aminoacids in the water requires at least 10 billion years of evolution. and we know earth is 4.5 billion years old, and life on earth, less than one billion years. the creation of something like the concious human brain troubles with gaps of several billion years the scientific theory and remains an unexplained mystery and an obscure landmark in earthly life. well, not for all of us.

The rate of time is NOT a constant. We measure the age of the universe (since the big bang) from the rate of time on Earth, although for much of that time there was no intelligent life on Earth and for some of that time the Earth did not yet exist. If the time was to be measured from a point at the very outside edge of the universe it would measure as being about a gross of hours, that is 144, in other words 6 x 24 hours. The rate of time is different and varies (in some locations, greatly) through out the universe.

congrats, Mark. and what did you use as a starting point, what did you plug into the equations? or did you simply do reverse engineering?

[@tonyspilotro2598]

The initial conditions were based on lambda CDM cosmology from WMAP measurements, inside a 106.5 mega parsec box containing a "glass-like" particle configuration of dark matter and gas with 6 billion hydrodynamic cells for each, roughly equivalent to the state of the universe 12 million years after the big bang. These particles were then displaced randomly, and started at a temperature of 245 Kelvin. Each cell has a mass resolution of 6 million and 1 million solar masses for dark matter and gas respectively. Each cell evolves into a different volume, using Voronoi tessellation. At each time slice hydrodynamics equations are performed on the 12 billion cells, and gravitational calculations performed using a tree of particle-meshes. Astrophysical modelling such as gas density, temperature and metallicity, ionising radiation, star formation, supernovas, supermassive black holes are also performed.

How the particles that go outside the boundary of the volume of this simulated universe are handled? Do they bounce off the walls, or are they wrapped to the other edge or do they just disappear?

[@warmag2]

+HarhaMedia Most likely periodic boundary conditions, so the simulation wraps from one edge to the other.

[@ScottSheppard]

+HarhaMedia I think the bounding cube was computed by how far the particles happen to spread. I don't think it is a physical phenomenon where particles would bounce off. It just defines how far particles got before they came to rest.

[@HarhaMedia]

+Vantte Kilappa I was thinking of this too, but then again rises the question that is the wrapping just done rendering-wise in this visualisation and the actual particles are just freely travelling not limited to any cube volume bounds, or that if they are in a toroidal space that actually wraps around on all 3 axes. If it's the latter case then vector math will become a bit wonky AFAIK. :D

[@HarhaMedia]

+Scott Sheppard This might just be it. I don't know how I didn't even think of this case, I was just constantly trying to think of ways they could handle the boundaries while it was just an illusion.

[@ScottSheppard]

+HarhaMedia They could have shown particles exiting past one edge of the cube and entering from another, implying that space wraps in on itself, but I did not see that.
