Objects in space are moving away from each other due to the expansion of the universe. This expansion causes galaxies and other celestial bodies to drift apart over time. The further away an object is, the faster it appears to be moving away from us.

The diameter must be expressed in a unit of distance/length - for example in light-years - NOT in years. The answer is that the distant parts of the Universe are going away from us, faster than the speed of light. Inside its own local space, nothing can move faster than the speed of light. But in the case of the expansion of the Universe, you might say that space itself is expanding. This makes it possible for objects to move away from us faster than light.
As space objects move farther apart, the gravitational force between them weakens. Gravity follows an inverse square law, meaning it decreases with the square of the distance between the objects. This results in weaker gravitational attraction as the objects move away from each other.
Briefly, redshift shows that most objects move away from us; this means that the Universe is expanding.
Objects move in circles on one giant sphere, with Earth at the center.He had a incorrect observation. Objects move in elliptical orbits on one giant sphere, with the sun at the center :)
Redshift in the universe occurs as objects move away from one another, expanding the universe. This indicates that the universe is still expanding, consistent with the Big Bang theory. The rate of this expansion, known as the Hubble constant, provides insight into the age and future of the universe.

Objects that move around other objects in the universe are said to be orbiting it, or in orbit.

Our universe does not travel through space in the traditional sense. Instead, objects within the universe, such as galaxies and planets, move relative to each other due to the expansion of space itself driven by dark energy. This expansion is happening at an accelerated rate, but it's not like a moving object in the traditional sense.

The expansion of the universe is causing galaxies to move away from each other, with space itself expanding between them. This expansion is driven by dark energy, a mysterious force that counteracts the gravitational pull of matter in the universe.
Their position relative to other objects in the universe changes.
Gravitational waves are created when massive objects accelerate, such as when two black holes merge or when a massive star explodes in a supernova. As these objects move, they cause ripples in the fabric of spacetime, which propagate outward as gravitational waves at the speed of light. Detection of gravitational waves provides valuable insights into the behavior and interactions of massive objects in the universe.
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.
Light waves from distant objects appear stretched due to the expansion of the universe, known as cosmological redshift. As galaxies move away from us, the wavelength of the light they emit is stretched, causing it to appear more redshifted. This phenomenon allows scientists to determine the distance and speed of objects in the universe.
