I love how a chunk of the population disappears before Gray even starts. It's almost like the population knows what is to come

yellow dwarf: 0:05 orange dwarf: 9:13 red giant: 10:58 brown dwarf (kind of): 12:29 sad giant: 12:42 disco party: 15:25-15:29 class O: 15:38 class B: 17:36 class A: 17:45 class F: 17:46 yellow giant: 17:48 orange giant: 17:55 red giant: 18:00 brown giant (why is giant): 18:07 depressed sun: 18:09 spontaniously combusts: 18:26

I love how comic the part where the Sun is almost in touch with the Earth, and the instant that happens the Sun changes from dying star to superheated blue giant in a few seconds. It's like the eldritch God has been ewakened and wanted to mortals to see them ascending before they eyes.

HERE COMES THE SUN

Oh! I finally get to use some of my obscure space knowledge! So, the things that start happening from 12:30 ish are kinda similar to an actual thing that happens in space: Brown Dwarfs! Brown dwarfs are, basically, failed stars. They're large celestial bodies made of gas, usually starting at several times the size of Jupiter. At these sizes and masses, the gas begins to be heavily compressed and squeezed, creating heat. However, brown dwarfs don't have *quite* enough mass for that pressure to start causing nuclear fusion of hydrogen into helium. Because of that, they give off significantly less energy, and no light. The tidal forces and high pressures can still give heat to orbiting bodies however (the same thing happens on a smaller scale between planets and moons), meaning that, even lacking the light of true stars, they do have the potential to support (some probably very strange) forms of life. Absolutely NO clue what happened that suddenly switched the sun back on near the end though

With a surface temperature of 820K, the Sun can no longer emit visible light, just infra red. It's now a brown giant.

12:28 "The sun is running out of AA batteries!" BB being like: *Gimme those sweet, succulent, AA BATTERIES.*

Gray never fails to ruin humanity in every game he plays. Truly an angel.

11:30 Now we know what Superman's family saw before Krypton exploded.

The extreme differences in the temperatures around the 9 minute mark is probably because you've effectively cooked the ozone layer off the planet, so daytime is super hot at the equator and night time is super cold. Ice is building up at the poles because it stays colder than it originally was much more of the time.

@7:30 Pallas is the third most massive asteroid ever discovered, comprising an estimated 7% of the mass in the solar system's asteroid belt. This asteroid has an average diameter of about 318 miles (513 kilometers), which is about 15% of the diameter of the moon. 🤔🥃😉 The MORE ya know!!😅 ::Addendum:: The Pallas Asteroid comes around roughly every 4.6 years..

I was listening to Black Hole Sun when this video popped up lmao😭

I love how Gray *STILL* doesn't understand the life percentage and thinks it's percent of the population remaining. 😂

planet sandbox idea:earth spins faster every minute

15:50 that would probably be the sun going supernova, so that's nice for everyone 1 foot away

Feels good to see gray bringing back universe sandbox

The way the earth just gave up and was eaten by the sun😭 right before the Sun gave up as well and left the game 💀

You accidently replicated how the solar system will sun will grow to Red Giant which will at its largest fill Earth's orbit. It will finally collapse into a red dwarf.

GRAY THE MYTH THE LEGEND!!!!

Im scared for Gray more and more with each upload.

Every time gray loads up this game the devs soul leaves their body a little more

I think the sun started going up in temperature because there was way too little mass for such a big volume. The usual density of the sun is 1408 kg/m^3, the density of air is 1 kg/m^3. The density of the sun at an .745 au radius would have been at 0.0003 kg/m^3. Which would be so gasseus that the molecules would hardly ever collide, and what ever light coming from the fusion at the core would just go straight through.

2:04 - I love how there's just a planet called "Sedna" 😂

The last part of the video just bursted me in laughter 🤣🤣🤣

4:22 Gray, that wenis shaped cloud is back.

Here Before The End Of The World

Please keep doing these Universe sandbox videos they are awesome

You know its a good day when Graystillplays uploads

At 14:00 the Venus fragment’s rotational period is “Positive Infinity” lmao

Oh jeez, what is this madmen about to do to us this time.... I am a vampire, leave me out of this :)

If you don't touch the temperature, it will continue going down, keeping the luminosity the same. Luminosity is what really counts. It would have turned the entire solar system into a blowout sale.

Pallas knows it's in a GSP video and has the right idea.

YAYY!! THE KING POSTED!

0:14 “all hail gray, the owner of all on earth” we all say in unison

16:22 "gray: hey earth how you doing earths like IrRaDiaTEd💀"

THE SUN IS COMING TO ALL THE BOYS AND GIRLS THIS CHIRSTMAS

I can't handle the summer heat well at all. I prefer going out in the evenings to watch the sunset if anything. Is much cooler out then.

There’s an audio track setting on this video, and I set it to Japanese. I turned GrayStillPlays into an anime!

Yes I was just loooking for one to watch I’m happy

Dear play, next time you play this game, please lower the temperature of Earth to the coldest it can possibly get.

The Skurge cameo at the beginning 😂😂🤣🤣

It's fun watching Gray simulate what the Sun leaving it's main sequence over the course of 100 years

A wise squid once said, august 12 2036, heat death of the universe.

Gray just turned into sephiroth by using supernova and i love it.

15:25 described Sun:Hah you fell in my trap card Gray:oh s*it Sun:Burn baby Burn

17:31 IS THAT FNAF MUSIC?! (Yes, I know it's actually the Toreador March/Carmen Overture by Georges Bizet, but Five Night's at Freddy's, which I've only seen the FIRST game played by Markiplier, admittedly made it more famous lol)

0:23 whelp, you gonna get more sun, lol. Nice loophole.

This is the earliest I’ve ever seen a Vedic after it uploaded

Gray is probably Florida's primary source of education

Bravo! So satisfying! I love it anytime you do sandbox sims and this one is fantastic! Glad you brought it back.

fun fact, due to the astronomically bizarre way our universe works (pun intended) the planets would still continue to orbited the spot the sun was at due to gravity (gravity waves specifically) only moving at the speed of light, meaning they would effectively be orbiting a phantom star of sorts. now i am in no means a credited source on this so take what i say with a grain of salt and check it out for yourselves, but science is so much weirder and cooler the fiction

10:15 Neat, Pallas is back

My honest reaction when Gray switched it from Celsius to Fahrenheit: 😔🥺

The maniacal laughter makes me happy.

Bro this is just part 2 of him making the sun become bigger than the entire milky way video 4 years ago. double the pain. double the death.

Haven't watched Gray in a hot minute

So glad universe sandbox has made a comeback. 😃

Never stop breaking reality, Gray. Also im so happy universe sandbox is back on this channel.

I love this return

Ah, classic Gray!, a true breath of fresh air.

I love watching guy when I go to sleep so chill

15:26 Sun Goku turns Super Saiyan Blue. 😂

This is just the future of humanity. The sun will just get older and swallow everything.

Rare footage of gray not using Fahrenheit

Nice to know that when the sun turns grey, I can take comfort in the fact that we won't be here much longer.

So glad graydude brought back his evil intent to destroy our solar system

YES YOU CAME BACK TO THIS GAME

Bro needs a raise because this is really funny

Gray essentially simulated the sun's slow growth into a red giant but faster.

The reason for the switch to getting cooler has to do with the ratio between luminosity and the surface area of the star to the energy content and volume of energy density. Since energy density is perportional to the radius cubed and luminosity is perportional to the radius squared, when the ratio between the two in natural units is perportional to 1 they are equal. Above 1, the perportion of something cubed becomes larger than something squared. But, below 1, the perportion squared is larger. So luminosity can only increase so far before it starts to lose its influence til eventually becoming negligible.

The Sun knew that it was Gray doing this, so it just died

Gray just likes making people from earth feel PAIN

Gray just simulating what would happen when the sun dies is insanely cool

Gray we need more of this game!!

I LOVE HIS UNIVERSE SANDBOX VIDOES. GIVE ME MOREEE

Watching Gray unknowingly simulate the actual death of the sun was enlightening. Even though he was in the dark as to what he was doing, it shed light on the death of our solar system. Thanks Gray for brightening my day.

Gray: “Destroys earth” Also Gray: Whoops

Awesome sauce

The sun was just waiting for Gray on earth to be in proximity just to become absurdly hot to end Gray as quick as possible

The most likely reason why the sun suddenly became really hot again at around 15 minutes is because the sun is, despite the low density, big enough to temporarily restart nuclear fusion, in fact big enough to fuse heavier elements like helium, carbon, oxygen and neon into heavier ones, which releases alot of heat and energy. Once it runs out of fuel (accumulated very heavy elements that the sun can't fuse even at that size) it no longer produces energy and cooled back down, and with the low density, very rapidly. Needless to say, such a star would have a very high concentration of heavy elements, with likely a very large metallic core, maybe much more than stars now.

More Universe Sandbox! Yes!

GRAYYYYY

Everytime I see Gray playing Universe Sandbox, I’m just glad that he’s not in control of anything in real life ….. otherwise, we’d all be dead 💀

This is the game that got me into Grey's videos

im watching this 1 minute after it came out

He's baaack!

Ah yes, my daily dose of GrayStillPlays. Finally!

Love your videos

Okay the fact it didn't go supernova until it was right near Earth's orbital set what's pretty extreme.

a star expanding without gaining mass.... that is a nova; that star is exploding

18:12 bro when the earth popped I died laughing LMFAO

Video idea: start adding more of what scientists say make something better for life until the solar system is destroyed wether if the earth gets uninhabitable or not Edit: don’t just add more of one factor that makes life better add the others

the sun suddenly getting hot as hell made my day now😂😂

Welp we're getting this event about 4-5 billion years early 😂

18:15 was this funny to anyone else?

humanity never had it that easy on this channel

That lack of personal space with the sun was disturbing as hell

To explain the sudden increase in tempature its because all the fusion power ran put, so the core began to colapse, in doing so it created more fusion, this time with heavier elements releasing more energy. Eventually the sun will just kinda disipate. This is actually how the sun will die irl.

You know, OI genuinely believe Gray is getting smarter with each universe sandbox video

This is Earth where I put everything I have If I have any lol
