Creating a MEGASYSTEM Using The LARGEST STAR IN THE UNIVERSE - Universe Sandbox

(I make a small commission on games bought through this link.)

Gear I Use (I make a small commision on any purchases made through the following links)

Original Setup

Planned Upgrades:

In this Universe Sandbox video, we are creating a solar system using Stephenson 2-18, aka the largest known star in the universe.

buying through this link gives me a small commission and really helps out the channel!

Tip for lava if you can’t get the temperature right- add water and color it orange. It’s cheaty, but it looks pretty good.

Your imagination went wild on this video! Keep up the good work

"We need a good name for this planet"

"Let's call it MegaPlanet!" 😂 so inspiring! Ppl wonder how do you do it.

[justinverdin]

love the camera upgrade and a awesome video !

Man I wonder what the time dilation would be between all of these planets. I have no idea if it would be significant but in my mind it should be huge due to the insanely massive objects they're orbiting. I'd like to see Stephenson 2-18 go supernova in this system.

I also made a system for Stephenson 2-18. First, there is Alina and Cura Po, very close to the star (Alina has a water cap, idk why.) Then, there is Omega A and B, two binary ringed rocky planets, both of them WOULD BE habitable, if it wasnt for their size. Omega B is 5x size of Earth, and Omega A is LITERALLY THE SIZE OF THE SUN!!! Anyway, we then have the last planet, the most normal one, called Fernus, wich has a moon, Salibe. This is also watery AND is only a little bit larger than Earth, so i think its habitable. Also there are a ton of satellites.

[Update] I also added a Sun sized gas giand called Rvacchu, with Vulibe, a very close habitable moon The colors of the gas giant are a very pretty orange, blue and cream.

I'd like to see a system with only asteroids and dwarf planets

[The_Darke_Lorde]

Well, I guess he just made Westeros with the Megaplanet

Also, Life in the Darkness would STILL get light from Stephenson, because the planet had light, and there's no reason why it itself wouldn't have light too.

Even though the black hole would eat a bunch of it if it ever crossed through Stephenson's line of sight with Lifegiver and LITD

A quasi-star (also called black hole star) is a hypothetical type of extremely massive and luminous star that may have existed early in the history of the Universe. Unlike modern stars, which are powered by nuclear fusion in their cores, a quasi-star's energy would come from material falling into a black hole at its core.[1]

Formation and properties
A quasi-star would result from the core of a large protostar collapsing into a black hole, where the outer layers of the protostar are massive enough to absorb the resulting burst of energy without being blown away or falling into the black hole, as occurs with modern supernova. Such a star would have to be at least 1, 000 solar masses (2.0×1033 kg).[1] Quasi-stars may have also formed from dark matter halos drawing in enormous amounts of gas via gravity, which can produce supermassive stars with tens of thousands of solar masses.[2][3] Formation of quasi-stars could only happen early in the development of the Universe, before hydrogen and helium were contaminated by heavier elements; thus, they may have been very massive Population III stars. Such stars would dwarf VY Canis Majoris and Stephenson 2 DFK 1, both among the largest known modern stars, in size.

Once the black hole had formed at the core of the protostar, it would continue generating a large amount of radiant energy from the infall of stellar material. This constant outburst of energy would counteract the force of gravity, creating an equilibrium similar to the one that supports modern fusion-based stars.[4] Quasi-stars would have had a short maximum lifespan, approximately 7 million years, [5] during which the core black hole would have grown to about 1, 000–10, 000 solar masses (2×1033–2×1034 kg).[1][4] These intermediate-mass black holes have been suggested as the progenitors of modern supermassive black holes such as the one in the center of the Galaxy.

Quasi-stars are predicted to have surface temperatures higher than 10, 000 K (9, 700 °C).[4] At these temperatures, and with radius of approximately 10 billion kilometres (67 au), or 14, 000 times that of the Sun, each one would be about as luminous as a small galaxy.[1] As a quasi-star cools over time, its outer envelope would become transparent, until further cooling to a limiting temperature of 4, 000 K (3, 730 °C).[4] This limiting temperature would mark the end of the quasi-star's life, since there is no hydrostatic equilibrium at or below this limiting temperature.[4] The object would then quickly dissipate, leaving behind the intermediate mass black hole.[4]
Edit : It took me 13 HOURS.

I'd love to see this get finished!

You should add more to this system, these are my suggestions.
Add UY Scuti and make a binary system with Stephenson 2-18 and UY Scuti.
Make a tidally locked planet that orbits on the side.
Create a hot gas giant if that works.
Add an asteroid belt right between the blue and green temperatures and put 3 or 4 dwarf planets in it, maybe add an elliptical orbit on one or two of them, try creating rings on one too!
Add a frozen planet that is VERY far from Sephenson 2-18 with a clockwise orbit and has 3 moons, one orbits on the side.
Add some of the terraformed planets you made in previous videos.
Make a neptune-sized rocky planet that is tidally locked with Stephenson 2-18. It has a very hot side and a very cold side.
To make it feel extra complete, put a few random asteroids around the system.

[whsecby]

Everybody's gangsta until game asks if you want to change the irl Stephenson's system with this one

[teight]

Hey uhhh chip, I made a moon that you can live on, its because of you your my inspiration thanks

[XMgamePlays]

We need a good name for this mega planet.
"Mega Planet"
Best name ever.

[Zeder]

Imagine for the inhabitants of a planet in such a giant system, they wouldn't even recognize the "seasons" in the way we do, they would simply see them like we see ice ages and warm phases in earths history, as eras of slow changes over thousands/tenthousands of years. They probably wouldn't even recognize their planet has seasons in an earlier stage, they would only measure it or research it when they have more advanced science and technology.

[devu]

Can you make a tri star system where planets revolve around 3 stars like Alpha Centauri but small.
