The Universe Coaster 

Mr Bones' Wild Ride is but an atomic scale blip compared to this. The ride never ends _because the universe will end before the ride does_

I love how you already had a setup that beat the heat death of the universe and still put in the effort to make it 90 times longer.

The fact they got back in line after getting off the ride 😂

The terrifying power of exponentials. This ride has a fear rating of infinity thanks to the existential dread it conjures.

13:09 These guys have goals beyond human understanding. After getting off the Universe Coaster, they went right back. Nothing else matters, just the coaster now. The Universe Coaster became their life. Their... universe.

I really appreciate the in depth explanation on exactly how big of a number that was. I've never heard someone try to read a number that big out loud. I figured we had terms past billions and trillions, but having never seen numbers bigger than that (that I can recall anyway), I never thought of how you'd even read them. It was also SUPER helpful that you gave us a point of comparison so we could really understand how big that number is. Never thought you'd help me enjoy math, thanks for the great content!

Marcel is the reason why I watch the POV videos before riding theme park rides

If you think riding it for that long is bad, imagine being stuck in the queue for it.

Chris Sawyer: "I'm gonna make a cool theme park tycoon game!" Marcel Vos: "I'm gonna make the biggest torture device with it."

I like how the guy who exits the universe coaster completely drained of energy after only god knows how many aeons directly walks back into the line to ride again. "Where shall I go? This is the only thing I've ever known. The universe coaster is my universe."

I once made a 4 minute wooden coaster in Rct3 and was very proud.

You've essentially built a binary counter with Wild Mouse coasters here.

At this point, Marcel has basically turned into AM from "I Have No Mouth and I Must Scream".

I want to get off Mr. Vos's wild ride.

came for the funny coasters, stayed for the existential dread

13:12 After all that time on the Universe Coaster there's probably nothing left in the universe except this rollercoaster, better get another ticket...

I can't stop laughing at 13:13 where the person just really wants to ride it again

“If there were a mile-high mountain of granite, and once every ten thousand years a bird flew past and brushed it with a feather, by the time that the mountain was worn away, a fraction of a second would have passed on the context of the Universe Coaster.” - Lois Duncan, _Stranger with My Face_

the way he goes from the intro into the joyous 'hello everyone' cracks me up

You made a clock to measure the life of the universe using rollercoasters as a unit of time! 😂 Beautiful!

I just counted my first atom today, I'll check back next year with an update. Wish me luck guys!

this is literally a rollercoaster of all time.

When you showed the number of years its gonna take i couldn't help burst out laughing so hard, the sheer absurdity is so fucking funny. Thanks for this great content, haven't laughed so hard at a video in a long time. Love your effort with these experiments. Just excellent

This is somehow one of the most terrifying things I've ever seen

Alternate title for this video: "Marcel Makes You Have an Existential Crisis while Roller Coaster Tycoon Plays Fitting Music."

The best part of this is that the initial 'slow coaster' barely even matters here. Even if you synced this setup to a 1-second long ride, the ride time of the final coaster in the chain is *still* orders of magnitude longer than the age of the universe.

I love how you put Mr. Bones in the middle. It's a must. Great video and discovery!

"Longer than the universe," is not hyperbole in this case. If you had started riding this coaster when the Big Bang happened, it still wouldn't be even remotely close to finishing by now.

I think the cruelest part of this coaster is not putting a toilet by the entrance!

Just when you think they can’t keep getting longer… truely we must have peaked. I guess i’ll see you all in 3 years when a new longest ride takes the crown!

And all that time, Chert continues to bop peacefully on his drum.

I've never seen the Bhuddist concept of Samsara and Nirvana so eloquently illustrated before!

If this record progresses any further, I imagine it will start to look similarly to the development mathematicians had coming up with new largest cardinal numbers, where they eventually became so large they were only expressed via abstract proofs showing it was larger than previous numbers rather than a number a lay person can actually read as being a number. Something like TREE(3) is unfathomably large, but it’s larger than other unfathomably large numbers like Graham’s Number in a way I myself can’t even begin to comprehend. Perhaps in the future we’ll have Coasters whose completion time cannot even be easily compared to the previous record holder by just showing them side by side, but can only be abstractly proven to somehow be longer.

My man goes full existential crisis mode over the happy fun rollercoaster game 11/10 I want to get off The Universe Coaster

A few years back when I watched the 12-year coaster video I suggested something might be possible by chaining lots of rides together, making each ride dependent on the previous ride. Looks like mission accomplished.

Oh my god he made a gearbox out of coasters lmao

Every atom in the Computer running this ride would be traveling apart from each other faster than the speed of light (along with every other Atom in the Universe) before this could even get close to a fraction of completing the ride. Very neat! This is why it is important to check reviews before riding any Roller Coaster!

Thanks for the clarification about Vanilla vs OpenRCT2 mechanics at the end - I was wondering why the station synchronization mechanics were different. Love that it works in Vanilla. Truly an epic creation; wonder if gaming media will pick up on this like the last few longest coasters.

That moment those guests were finally released from their journey and then went back into the queue for a second round!

An update to my favourite "series" of sorts! I'm unsurprised that the number got so absurdly large as soon as that synchronization method was figured out, once you move from multiplicative growth to exponential growth things can get massive quickly. It's entirely possible there's still room for improvement, like a way to abuse game mechanics that allows us to use powers of three rather than two, but for our mere mortal minds this is the limit. We've reached an incomprehensible scale, any improvements may be much larger but equally incomprehensible. As a side note, I'm amazed I never knew that one-tile-offset stations can still synchronize. That opens up a ton of possibilities.

I'd love to see an interview of Chris Sawyer by Marcel Vos, and then, an interview of Marcel Vos by Chris Sawyer.

When I was a child, I had a terrible fever and one night I had the most scariest nightmare in my life that to this day still remains the scariest, but it wasn't anything with zombies or monsters chasing me, it was indescribable as to what it is, I just remember the feeling of it and things like how you described counting the atoms of the universe brings back those feelings. It was as if I was forced to count every atom of the universe and if I messed up, I had to start all over. It's just that feeling of whatever you do in your task, it'll never end. I get the same feeling as an adult, when I have to work on a stack of papers and I work on it for hours, days, weeks and when I look at the stack, it seems like it hasn't changed at all or has grown even larger.

I cannot believe someone actually used the same login of a gear shift ratio to extend ride length with such a ridiculously efficient method. Well done Marcel! You continue to astound me!

I thought that you couldn't become insane watching a video about a game where you build and manage theme parks. I was wrong.

Universe Coaster looks too intense for me!

"I always wondered how the Warp Trains worked. How a train could get you to your destination in a couple seconds. But it really just enters a wormhole. It stays in that dimension for millions or billions of years until it happens to arrive at the right destination. And when you get off your memories are wiped. But I wonder what your life truly is, if you spend eternities in that torturous limbo, and mere hours outside of it, where do you truly exist?" ~Guy returning to Universe Coaster, probably.

there are plausible models of the universe in which this ride will outlast *protons*. It's plausible that when there is nothing left in the universe but photons, leptons, and black holes... you won't have gotten to the exit yet.

Amazing video. Can’t lie the explanation of how insanely long it takes was amazing

Man that intro was 10/10. Love this channel.

This is it. Besides the 12 hour drown-a-thon, this is my all-time favorite Marcel video. Great job, especially on the script!

This week on RCT, existential dread.

I'm so glad this was in my recommended. Absolutely absurd extremes of a game I adore and I love it.

Mr Bones, can I pleeease get off your wild ride!

You did it, the madman did it. I can't believe you made a coaster that takes more years to complete than the amount of cookies I have...

Headcanon: The ride is somehow rather fun, or at least fun enough not to be true existential torment. This is why someone will get off of it and say "Huh, yeah, let's go for round two"

This must probably be one of the geekiest videos on youtube and I love everything about it.

the fun thing is even if the first coaster in the system took a millisecond to complete, with the 253 layers of reduction it would still be absurd

Funnily enough, I re-watched your longest coaster videos *yesterday.* I thought, "Surely, there has to be some way or another to create a binary counter. I know it hasn't been figured out, but come on, it just has to be possible." I knew it would come eventually, but I expected to have to wait longer. It's quite nice that the ride time comes out to about a twentieth the number of atoms in the observable universe.

That the game can even compute with these numbers is incredible. The last part of the video shows perfectly, why your channel is not any channel. Great stuff!

Seems like quite the community effort. Thank you to everyone who was involved in helping make this video possible. Might be one of my favorites of the channel now.

Great video, glad I could help!

This is where it all ends. Marcel has created the true longest ride in all of RCT.

I never thought i would find the most epic video opening in rollercoaster tycoon. Hats off Marcel

I was going to comment "couldn't you make the wild mouse coasters longer?" but seeing the coaster take more years than the number of atoms in the universe kinda took the wind out of my sails 😆

how can a video about RCT and some equations stuff be THIS INTERESTING AND THIS FUNNY??? you're a genius. thank you and your discord group for helping delivering this video.

This is the most epic RCT video ever. The intro is 🔥

your videos never cease to amaze me. i don't even play RCT anymore but still appreciate your creativity. great job 👏!

You've outdone yourself, Marcel. This is absolutely absurd. You've created a ride with a length that is literally unfathomable.

Still sounds better than getting on a Zamperla Volare.

I'd love to see these rides packed full of guests. It could be a case of pick your own poison, with the uber long & the 3000+ year looping coaster being the "shortest".

i was almost anticipating we'd get to googology levels of ride time. perhaps for the next coaster? :]

Woahhhh absolutely love this Marcel! Keep it up!!!

This is hilariously awesome. I've really enjoyed your videos, I played RCT a lot as a kid but with no real in depth knowledge of the mechanics of the game. Really cool watching you push the limits and it says a lot about the game itself.

This video is basically a template for explaining very complicated things in an engaging, and understandable way Keep up the great work Marcel! 10/10

The ride never ends!

Now this is content, originality and effort! I love how much dedication Marcel puts into this and always finds out a way to reinvent a 20 year old game (which is still a masterpiece, of course)...

Marcel dropping that existential dread harder than accepting I'm going to die anyway.

I love your opening narration. What a fantastic story, you really painted a picture with words

I never thought that my youth sentiments (Roller Coaster Tycoon) would still entertain me years after. Thanks Marcel!

This video filled me with absolute existential dread.

i'm actually... scared. thank you.

Marcel, making math fun since 2016!

can’t wait until you somehow find a way to make a rollercoaster even longer again

I didn't expect cosmic horror when clicking on this video but here we are :D

Great vid. Love your work

this is a top tier video. i think i'll add this to my collection.

You could literally display this in a museum Marcel this is beautiful

I like the subtle nod to 'Mr Bones' Wild Ride' with the skeleton scenery in the middle of the long coaster

Damn. I've been working on this since your last longest coaster and was also trying to basically get a clock system going like you did. I couldn't figure it out with the heights and the synchronization, though. Probably should have joined the discord and talked to people who actually know how the game works

Hahha your introduction is awesome. How you started this episode with a kind of creepy intro is awesome. Marcel you never fail to impress with your videos. And to make it feel like it is really creepy to think about such rides. I am glad I am not a mechanic there who is told he only needed to work until the universe coaster made one full lap. Hahah You make a serious but really fun game into something creepy deep and terror. I love it.

Imagine if you could sync stations with the exit of a maze Now tie the station of the first wild mouse to the exit of the longest possible maze with one guest allowed in at a time (who also walks as slowly as possible) Once the universe coaster finishes a lap maybe then the first second of eternity will have passed

This reminds me of the crazy gear ratios people do

i love when bit counters show up in unexpected places

That’s a perfect example why your videos are so great! Enjoyed (the ride and the) video a lot 👍👍👍

Impressiv as the first long coaster project. 👍 Now do this with the new Savefile format from OpenRCT2 and his new ride/land limits. 😂🤪

I've watched so many of your videos over the years and while all of them are fascinating this one quite literally blew my mind. I Seriously can't give you enough compliments for the work and interesting math you calculate for your videos. Can I ask how in the world did you fast forward it to the point where the guests actually completed a ride? Even with the highest speed to fast forward in OpenRCT it seems like it would still take ages perhaps even lifetimes to complete a circuit.

That intro was bomb! nice video, man :D

We've done it, humanity has made Mr. Bones' Wildest Ride. M R . B O N E S S A Y S T H E R I D E *N E V E R* E N D S

Man... I follow your channel since a while now, enjoying pretty much all your video. THIS ONE man.. This one is actually the best so far. Enjoyed it from the initial idea, the execution, the storytelling, explanation and video montage. Thanks Marcel, you da real MVP.

First, there was Mr. Bone’s wild ride now there is Mr. Bone’s universe coaster.
