How would time flow if we stayed absolutely still?
According to the general relativity, gravity and speed affect time. We humans have pretty much the same feeling of time and as i understand it its because we all have:
A) the same acceleration from the gravitatinal force of the earth
B) the same speed as we move with the earth round and round it self, the sun and along with the solar system in very big speeds.
Lets suppose for a moment that we somehow managed to launch a spacecraft in such a way that would cancel all movement, and stayed absolutely still on space. And lets suppose no object is close to that to affect it with any gravitational force. How would time flow if there was an observer there? One could ofc argue that it would stay the same because relative to us, the universe still accelerate, and someone else might argue "you'd just age faster" but i think there is more to it.
Just like when approaching light speed weird but interesting things happen, i think that when we approach absolute 0 speed again weird but interesting things will happen...
Does anyone know the answer to this? Otlr have a hypothesis about it?

Time always moves no matter what

People do experience the cession of time every day, when time for them stops. None of them have written anything about it.
It is called death.
You can experience it but it is illegal to do so because it is Top Secret.
Apparently If you do it you are not allowed to publish it.

If you were riding on the highway, in the back of a VAN with no windows, and stood absolutely still, everything around you might be STILL on the inside, but the VAN is STILL running on the highway.
The movement on the highway could be likened to TIME.
TIME could be defined as " A constant motion in the direction of the fourth dimension that is INHERENT in ALL matter." We do not see this motion as we are only aware of our 3 dimensional surroundings. And all matter that is around us is ALSO moving at the same SPEED and direction in the 4th dimension.so everything stays in place as the stuff in the back of the Van around us.

You misunderstand Relativity. All speeds are measured relative to another object. There is no absolute zero speed. There is no way to define speed of an object relative to space.
If there are two ships in empty space moving very fast relative to each other, we can't say which is moving and which is at rest. Each can say that it is at rest and the other is moving. People in each ship will see time in the other ship flowing slow. Each ship's passengers will see the passengers on the other ship moving in slow motion

Questions about how fast the earth--or anything, for that matter--is moving are incomplete unless they also ask, "Compared to what?" Without a frame of reference, questions about motion cannot be completely answered.
Consider the movement of the earth's surface with respect to the planet's center. The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.
As schoolchildren, we learn that the earth is moving about our sun in a very nearly circular orbit. It covers this route at a speed of nearly 30 kilometers per second, or 67,000 miles per hour. In addition, our solar system--Earth and all--whirls around the center of our galaxy at some 220 kilometers per second, or 490,000 miles per hour. As we consider increasingly large size scales, the speeds involved become absolutely huge!
The galaxies in our neighborhood are also rushing at a speed of nearly 1,000 kilometers per second towards a structure called the Great Attractor, a region of space roughly 150 million light-years away from us. This Great Attractor, having a mass 100 quadrillion times greater than our sun and span of 500 million light-years, is made of both the visible matter that we can see along with the so-called dark matter that we cannot see.
Each of the motions described above were given relative to some structure. Our motion about our sun was described relative to our sun, while the motion of our local group of galaxies was described as toward the Great Attractor. The question arises: Is there some universal frame of reference relative to which we can define the motions of all things? The answer may have been provided by the Cosmic Background Explorer (COBE) satellite.
In 1989, the COBE satellite was placed in orbit about the earth (again, the earth is the frame of reference!) to measure the long-diluted radiation echo of the birth of our universe. This radiation, which remains from the immensely hot and dense primordial fireball that was our early universe, is known as the cosmic microwave background radiation (CBR). The CBR presently pervades all of space. It is the equivalent of the entire universe "glowing with heat."
One of COBE's discoveries was that the earth was moving with respect to this CBR with a well-defined speed and direction. Because the CBR permeates all space, we can finally answer the original question fully, using the CBR as the frame of reference.
The earth is moving with respect to the CBR at a speed of 390 kilometers per second. We can also specify the direction relative to the CBR. It is more fun, though, to look up into the night sky and find the constellation known as Leo (the Lion). The earth is moving toward Leo at the dizzying speed of 390 kilometers per second. It is fortunate that we won't hit anything out there during any of our lifetimes!

There is no such thing as absolute zero speed - it is utterly meaningless and the whole point of special relativity - there are no preferred inertial frames.
Rate of time flow in a PARTICULAR reference frame can often be usefully described by introducing the concept of 4-velocity. This is a 4-vector (like all vectors in relativity) and like all 4-vectors, has the same magnitude for ALL reference frames. That magnitude happens to be ‘c’, the speed of light. In YOUR reference frame, the space components of 4-velocity are zero, and the time component of 4-velocity must therefore be ‘c’. If you are observing motion of other reference frames, the space components of 4-velocity will not be zero, so the time component must be slower than ‘c’. In other words, you see a slower clock rate for the other reference frames. You will never see a change I your own frame.
Similar ideas apply to gravitational fields, but in that case two reference frames that are at rest with respect to each other, but in different gravitational fields, will experience time dilations due to the change in orientation of their reference frames due to spacetime curvature. You can make the same arguments about 4-velocity, but unfortunately you have to introduce the difficult concept of ‘connections’ when comparing different locations. Each observer of course sees their time flowing at exactly the same rate it always has.

Time still flows when you are "absolutely still". If you were very far from any galaxies, and not accelerating, the rate of time is about 1/2 second per year faster than on the surface of Earth.
When you are close to a gravity source, such as the Earth, Sun, or a neutron star, time goes slower (relative to observer at infinity). Conversely, the rest of the universe seems to go a bit faster.

I've read that we perceive time only because of changes (ours, others, the environment). So I think you're on to something.

We ahould theoretically see a slight slowing of the passage of time when completely free of the effects of gravity and motion, buts ks possible we'll never know for sure. Even our sun, which is tiny compared to some of the stellar heavy hitters out there, have an sphere of influence more than a light year in radius. Our entire galaxy is influenced by the supermassive black hole at the center, and its possible theres no place in the entire universe completely free of the effects of gravity and motion

It's impossible. Since the entire universe is in motion and is expanding, the fabric of all space-time itself being constantly stretched, there's no way to stay absolutely still. The perpetual motion of all things is a law of the universe. There is only an illusion of ever standing still by matching the motion of something else moving so that the movement relative to one another creates the appearance of stillness between them.
Something I wonder is what effect does general relativity have on rotating spheres like planets and stars. Their rotation means that time along their rotating axes is passing more quickly than time along their relatively faster-moving equatorial surfaces and that time increasingly distorts in the sphere the further away in the sphere you get from its rotating axis. So what effect, if any, does this increasing torsion of time have on the rotating sphere itself and/or on its surrounding environs, especially in very large or quickly rotating spheres where the relative speed of motion between the axis and the equatorial surface is great?
