and where is the galaxy taking us then?

Based on how Earth is doing, she might be taking us to the big farm upstate. :(

Earth is fine, it’s seen worse than humanity. Geology doesn’t care about what biology does.

Ane like all good mothers one day she will grow into a red giant, engulfing her children and obliterating all life on earth.

Did everyone forget about the galaxy? It’s also a giant circle, and the sun orbits it like we orbit the sun.
Perhaps the real question should be “Where is the Galaxy taking us?”

“Where is the Galaxy taking us?”
Towards the andromeda galaxy which is over twice the size of the Milky Way. We are hurtling towards each other at about a quarter millions miles per hour.
For thousands of years after you die, that little fuzzy spot near Cassiopeia will slowly get larger and larger in the sky, and in about a four billion years, long after the Earth’s oceans have dried up and the sun is a giant, reddish monster hovering in the sky, and our magnetic field will have long since died out, our atmosphere will have been mostly stripped away and the weather will feel like being on the highest mountains in an oven, the night sky will be covered with a dazzling display of the Andromeda galaxy overhead, spiral arms visible with the naked eye stretching from horizon to horizon.
We will merge, in a series of passes through each other, with almost no stars actually colliding most likely, although a good number will be ejected into the emptiness of intergalactic space, and will finally settle into a new shape, and may trigger a new phase of star formation as new clouds of gas and dust collide and collapse in the new super-galaxy.

First thank you for filling in OP’s coverup of Mama’s intentions.
We will merge, in a series of passes through each other, with almost no stars actually colliding
So then, we’re just going for a ride to a farm upstate :(
RedSnt@feddit.dk 5 hours ago
As far as I know we’re headed toward another galaxy. Luckily we’ll all by long gone by the time that collision happens.

Fun fact, we do not just orbit the galaxy in a circle, we also have a motion perpendicular to that circle. We oscillate up and down through the plane of the Milky Way. The Milky Way is super thin, like super ultra thin. If the Milky Way were a pancake, it would only be the thickness of a sheet of paper, a sad pancake indeed. However in terms of human scales it is still huge, so we have a large way to travel. Our galactic orbit is tilted as compared to the galactic plane, so throughout the cosmic year we move up and down as compared to the center. A motion of 100-200 light year, so pretty big. That orbit also has procession, so we move through different parts.
The galaxy itself is also moving, although at that scale it’s easier to thing of the galaxy to be stationary and other galaxies moving towards or away from us. In general we are all moving towards a galaxy cluster known as “The Great Attractor” as it is the most massive (except for your mom).
It’s also often forgotten that our sun isn’t the only star moving in the galaxy. All of the stars orbit the galaxy in a lot of different orbits. And some don’t orbit at all, instead moving with escape velocity to get flung outside of our galaxy. Some have their own orbit in companion dwarf galaxies that in turn orbit our own galaxy. It’s easy to think of a galaxy as a fixed thing, with all the stars in the same place moving together like on a disk. But this isn’t the case at all, stars aren’t bound together and can follow their own path. Over time their relative positions change and the constellations we know won’t exist anymore.
The structures we see in galaxies like spiral arms for example are only structures in the same way a wave in the ocean is a structure. It is clearly a thing that exists, with properties we can at least somewhat constrain (like size for example). But the water inside that wave is just water like everywhere else. At one point it’s part of the wave and then at some point it no longer is.

There’s also no reason to believe that expansion isn’t happening in a spheroid pattern. The big bang wouldn’t have been like a blunderbuss, more like a naval mine suspended in the abyss, exploding in all directions.
For that matter, did the big bang ever cease, or has it continued to spew out new energy, and we’re just so inconceivably far out that our entire observable universe is just one small section of a relatively narrow range of distance from the center?
Lastly, if the big bang is like a faucet, what if black holes are like drains in a tub, or in other words wormholes leading back to whatever realm everything came from before being spewed out by the big bang?
Everything in the universe is cyclical; there’s no way something doesn’t complete the circuit, even if it’s just a big crunch.
Donkter@lemmy.world 8 hours ago
This model does assume the big bang happened in a spheroid pattern. It’s just flattened to add time as an axis from left to right cause you couldn’t represent time otherwise.
flying_sheep@lemmy.ml 5 hours ago
There’s also no reason to believe that the big bang happened at one “point”. I believe that the universe (and therefore the big bang) are infinite.
Everything is relative, so something infinite can still expand: since there’s no absolute speed, galaxies can move away from each other everywhere, at all times.

Either you get tossed to the curb by mom and you are cold and alone after being so used to the warmth and the plant is dead (flung out of orbit), or get murdered by her (red giant… engulf the system)

It’s my understanding that the specific direction on this relative motion graphic is just made-up, but it does do a good job of reminding people that we’re orbiting the galactic center.

Does the sun actually travel in a straight line, or do the orbits of the planets wobble it, and to what extent?
rImITywR@lemmy.world 18 hours ago
Everything in the solar system (even the Son) orbit around the center of mass of everything in the solar system. This epicenter is just outside of the Son, on the side that Jupiter is. So the Son wobbles by a little bit more than 1 of its radii.
MagicShel@lemmy.zip 17 hours ago
Sun, I am disappoint.
tomiant@piefed.social 17 hours ago
I am under the impression that straight lines don’t really exist.
scala@lemmy.ml 13 hours ago
They don’t. There is new research where the universe is constantly expanding, while we are traveling in an orbit around the sun, the universe is exponentially expanding, growing outward kinda like a reversed funnel.
wonderingwanderer@sopuli.xyz 8 hours ago
I think the graph shows relative position of the planets from the sun, so the straight line is just a baseline.
Like if you jump up and down on a plane, and the graph just shows you moving a couple of feet up and down rather than including the entire altitude change of the plane itself
Alcoholicorn@mander.xyz 13 hours ago
Juipiter’s orbit wobbles it, as others said, the barycenter of the system is outside the sun’s radius, but the scale of the planets vs their orbits is so great such a small wobble is imperceptable if you can see multiple orbits.
