You can’t get to this star in Elite Dangerous, but you can get to VY Canis Majoris which is 1420 radii

what is the minimum and maximum size of a star? i.e. what is the minimum mass to ignite hydrogen fusion or whatever generates heat, and what is the maximum size where it just collapses into a black hole?
CrazyLikeGollum@lemmy.world 5 weeks ago
The minimum is about 80 Jupiter Masses. Smaller than that and you can’t start fusing.
Maximum size is harder to answer. It’s determined by the Eddington Limit. Which describes the luminosity at which radiation pressure is enough to overcome gravity for a certain mass.
It’s thought that the maximum mass of a star is somewhere around 150 solar masses, but there’s some evidence to contradict this, as we’ve seen a handful of very old stars with masses or luminosities higher than they should be.

“Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.”

ininewcrow@lemmy.ca 5 weeks ago
Here’s the galaxy and our approximate location in this system. To give you an idea of scale … the galaxy is estimated to be about 100,000 light years across. Meaning that if you could travel at the speed of light (which is impossible), it would still take you 100,000 years to cross the galaxy from edge to edge.
zea_64@lemmy.blahaj.zone 5 weeks ago
100000 years from an outside perspective, but because of time dilation you could make it take arbitrarily little time from your reference frame.
School_Lunch@lemmy.world 5 weeks ago
I liked the character’s from Project Hail Mary perspective. The fact that we experience less time the closer we are to the speed of light is almost like an invitation to explore the stars.
Another things that gets me is the time experienced by black holes. We would think of the black hole at the center of the galaxy as some enduring, permanent thing, but with so much gravity, from the black hole’s perspective it may only exist for a fraction of a second.
ininewcrow@lemmy.ca 5 weeks ago
I don’t fully understand how the science and theory works around all that … all I understand is that it is so unbelievably far away that in order to cross any of those distances or even think about crossing those distances, it begins to break our normal understanding of speed, distances and time.
Rhaedas@fedia.io 5 weeks ago
Epic Spaceman on Youtube had a great scale realization method. If out galaxy was the size of the United States, our solar system would be somewhere around the city of Denver. The neighborhood stars we can individually see with our eyes would be the area of the Denver city lights. The Sun would be the size of a red blood cell, and the solar system's expanse would be the size of a fingerprint.
ininewcrow@lemmy.ca 5 weeks ago
I always loved those examples that show the scale of planets, stars and systems. I remember years ago before I got on the internet (yes I’m that old), reading a comic or book, I can’t remember where … all I remember is the cartoon and illustration.
If you made a scale model of the galaxy and fit it in between the earth and the moon … our sun would be the size of a marble and it’s nearest neighbour would be about a mile away. And some of the largest stars would be about the size of an average office building.
ininewcrow@lemmy.ca 5 weeks ago
Here’s another perspective … this is local galactic group. Our nearest galactic neighbor is the Andromeda Galaxy … it’s located about 2 million light years from us. Again, if you could travel at the speed of light (which is impossible), it would still take you 2 million years to get there.
Another way of thinking of it is that the light we see from Andromeda today started it’s journey when our first prehistoric human ancestors first evolved in Africa 2 million years ago.

If you could travel at the speed of light, the only tim it would take you is the time spent speedign up and slowing down. Traveling at the speed of light stops the time for you.

It’s just highly improbable to cross the galaxy in less than 100 000 years. You just need a device which generates infinite improbability and that’ll pass you trough every single point in the universe simultaneously and you can just stop where needed. Side effects may apply.

Stalinwolf@lemmy.ca 5 weeks ago
I was on 2C-B and lounging about in my brother’s room, staring at a big glowing plastic moon I had bought for him as a joke, when somehow the word and concept of it sent me spiraling down a rabbit hole of cosmic realization. At first the moon (or perhaps my thoughts surrounding the moon) began to rotate like a planetary body, becoming a parent star in a galactic arm, and eventually the central mass of a galaxy itself, ever turning with long tendril arms orbiting around its perimeter.
As the question of it grew, it became the universe itself, on a profoundly metaphysical level, and I came to the realization that every single living organism, both here and elsewhere in the cosmos, are not so much a part or some greater plan or design, but are instead just individual cells and appendages of recently awakened universe. One that has blinked its eyes from a deep sleep and has slowly become self-aware. And just as a child born blind will at some point use their hands and discover they have a body for the first time, we are tiny (but not insignificant) appendages of that universe discovering and exploring itself, trying to make sense or what it even is.
I found immense comfort in the idea that there is no greater meaning to everything than that. We’re just a part of something bigger that is at this very moment trying to make sense of itself, and I don’t need more than that.
