True
True. The gravitational force between two objects decreases with distance, and the vast distances between our sun and distant stars in other galaxies make their gravitational influence negligible. While gravity acts over infinite distances, the effects become incredibly weak at such scales, making it difficult to perceive any significant gravitational interaction.
The gravity of the galaxy's mass, primarily from stars, gas, dust, and dark matter, is responsible for holding these components together. The gravitational attraction between these elements counteracts the outward pressure from stellar processes and cosmic expansion, maintaining the galaxy's structure. Additionally, dark matter, which does not emit light, contributes significantly to the overall gravitational field, further binding the galaxy's mass.

The largest black hole has the strongest gravitational field. We do not know where that would be, but it is most likely in the center of a galaxy somewhere in the universe.
Yes, all objects with mass exert a gravitational force on each other regardless of the distance between them. This force follows the universal law of gravitation, which states that the force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them. This explains why the sun and a star in another galaxy can still feel each other's gravitational pull, even if they are very far apart.
True
Galaxies do exert significant gravitational attraction on other galaxies. For example, the Greater and the Lesser Magellanic Clouds are galaxies that orbit our own galaxy, the Milky Way. In that sense, the stars in one galaxy do have a gravitational interaction with those in other galaxies. Of course, the more distant galaxies have correspondingly less gravitational interaction with ours.
A satellite galaxy is one that revolves around another galaxy.
No. It's the mutual gravitational force between it and the earth that keeps a satellitein a closed orbit, instead of flying off away from earth in a straight line.Technically, there's no such thing as "outside of" the gravitational force of anything.We can calculate the gravitational force between a star in a distant galaxy and the earth.In fact, we can calculate the gravitational force between a star in a distant galaxy and you.The force is pretty small, but it's there.
true
The farther away another galaxy is from our solar system the less effect that the gravitational pull will have on that galaxy.Thus allowing the other galaxy to travel at a faster rate.
There is no limit, and it never ends. The formula to calculate the gravitational force at any distance has no limit in it. The force of the gravitational attraction between the earth and another object can be calculated even if the other object is in another galaxy. Of course, the farther apart two masses are, the smaller the gravitational force between them is. So when you're far from the earth, there's probably something else nearby that attracts you with a stronger gravitational force than the earth does. But no matter how far away you are, and how weak it gets, the earth's gravitational force never ends.
By gravitational pull from the galaxy
Massive means there is a lot of mass - and gravitational attraction depends on the amount of mass. The amount of gravitational attraction also depends on the distance - i.e., the effect will be less at larger distances. The gravitational attraction between galaxies is strong enough to make galaxies in a galaxy cluster stay together - for example, in our Local Group.
The force of gravitational attraction between two masses is never zero. There is a force of gravitational attraction between a hair on your head and the smallest moon in the farthest galaxy. The force may be too small to measure, but it's never zero.
A point where the center does not have gravitational pull... once things stop orbiting thats it for the galaxy
