Neither. The definition of the 'universe' is: Everything that exists.
And since that includes us, we are inside of the universe.
The Universe is, however, thought to b expanding, and expanding faster at its outer edge. So the outer edge of the Univere is moving away from us. We, on the other hand, are moving away from the center of th e Universe (wherever that may be) so we are at the same time getting more distant from the center.

Why are the blueshift and redshift useful in the study of the universe?
Redshift and blueshift are manifestations of the Doppler effect. This lets us determine whether a star, or a galaxy, is moving towards us, or away from us.

Are different galaxies moving in your universe if so in which direction?
Most galaxies move away from us - the farther they are from us, the faster they move away from us. This means that the Universe is expanding.
What does it mean when the color of an object in the universe shifts toward red?
When the color of an object in the universe shifts towards red, it indicates that the object is moving away from the observer. This phenomenon, known as redshift, is caused by the expansion of the universe and the stretching of light waves as they travel through expanding space.
Do galaxies move towards us?
At least one galaxy is moving towards us: the M31 Andromeda galaxy. Most galaxies however are so far away from us that the distances between are affected by the metric expansion of the universe. They may move towards us relative to their local metric, but the distance between us and them still increases.
How can you tell that some galaxies are far away and moving rapidly towards us?
You can tell by the blueshift in the spectrum; the only reasonable explanation for this blueshift is the Doppler effect. - Please note that most galaxies are moving away from us, not towards us.
How do astronomers determine if a star is moving towards or away from us?
Astronomers use the Doppler effect to determine if a star is moving towards or away from us. By observing the shift in the star's spectral lines towards the blue end of the spectrum (blueshift) or the red end of the spectrum (redshift), astronomers can infer the star's motion relative to Earth. Blueshift indicates the star is moving towards us, while redshift indicates it is moving away from us.
When all galaxies are moving away from us we must be located at the center of the universe?
The observation that galaxies are moving away from us is a result of the expansion of the universe, not because we are at its center. The universe is expanding uniformly, which means that every galaxy sees other galaxies moving away from it, regardless of its position. This phenomenon is described by the Big Bang theory and the cosmological principle, which states that the universe is homogeneous and isotropic on large scales. Therefore, no specific location can be considered the center of the universe.
What is red shift and blue shift why are these effects useful in the study of the universe?
Red shift occurs when an object is moving away from us and blue shift is the opposite. This is important because it has been observed that most things in our universe are red shifted, and thus, moving away from us. In fact, it has been calculated that the way these objects are moving (th direction of them) points to the fact that they were all in a centralized point and are all moving away from it--as if an explosion created the universe. This theory of creation is called the Big Bang Theory by the way.
What can the Doppler effect tell us about in astronomy?
It can tell us whether a star, or a galaxy, is moving towards us or away from us.
How many galaxies are approaching milky way galaxy and how many are moving away related to the cosmological red shift?
Most galaxies are moving away from us. Only a few galaxies, which are nearby, are moving towards us.
How is the Doppler effect used in astromomy?
It is used to determine whether an object is approaching us, or moving away from us. It turns out that - as can be seen from the Doppler effect - most galaxies are moving away from us. In other words, the Universe is expanding.
