Space itself is expanding or the volume of space is expanding: Explained.

"This following statement introduces the idea that there are two possible ways to describe the expansion of the universe. One perspective suggests that space itself is expanding, while the other posits that it's the volume of space that is expanding. 

The Big Bang theory, which is a widely accepted cosmological model, asserts that space itself is expanding. This notion is derived from observations made by astronomer Edwin Hubble. He noticed that galaxies farther away from us are moving away at greater speeds, a phenomenon known as Hubble's Law. The idea of an expanding universe is a central component of the Big Bang theory.

Hubble's observations showed that galaxies are not only receding from us but also accelerating in their recession as we look toward the edge of the visible universe. This observation suggests that the distance between galaxies is increasing, and it's happening at an accelerating rate.

The statements argue that the increase in distance between galaxies can be interpreted as an increase in the volume of existing space. It emphasizes that this expansion of volume doesn't mean that space itself, as a physical entity, is expanding because space is considered to be without a physical presence. Instead, it means that the volume of space is increasing, particularly towards the edge of the visible universe.

In conclusion, the statements advocate for the perspective that it is the volume of space that is expanding, not space itself in a physical sense. This distinction is made to clarify that space is not a substance with physical properties but rather a conceptual framework within which the expansion occurs."

If you're wondering, the Big Bang theory says that space itself is expanding; But I say that it is the volume of space that expands. which is explained below.

The Big Bang theory generally states that space expands. This idea is actually based on Hubble's observations. Hubble showed that galaxies farther away from us are receding faster than nearby ones—a fundamental observation now known as Hubble's Law. The idea of an expanding universe is a cornerstone of the Big Bang theory.

Hubble's fundamental observations specifically established that galaxies are receding and accelerating incrementally as we look towards the edge of the visible universe, meaning that the distance between the respective galaxies is accelerating towards the edge.

Therefore, according to the mathematical and geometric interpretation, the increasing distance between galaxies means the corresponding increase in the volume of existing space, this increase usually means that space is expanding and does not mean that space itself is expanding, because space does not have a physical presence, so space is physically expanding. cannot, it is instead increasing its volume towards the edge of the visible universe.

That is why I say the volume of space, which expands.
