    Atoms Space
In summary, the discussion revolves around the similarity between the empty space in an atom and the vast voids in the universe. The concept of "space" and its definition is also brought up. While the popular idea is that atoms are mostly empty space, there is more complexity to this concept.

New to this blogging, forum internet stuff so bare with me.
Does anyone know if there is a similarity between the empty space separating the nucleus from the electron cloud of an atom, and the empty space found in the vast expanse of the inter galactic voids. The statement "Matter is composed mostly of empty space" implies they are the same. Is there anything special about this 'atomic void'

What do you mean by "the same"? What characteristics did you have in mind when you are comparing them?

"Space" is space. Why would the space be any different? Granted, at some length scale, QM may have something to say about our ability to define what we mean by a "length", so the concept of "space" may require rethinking. However, based on our current understanding, and the formalism of the physics that we have used to describe atoms and celestial bodies, there is no difference.

Note that the popular idea of atoms being made up mostly of empty space is actually much more complicated than it appears. I know we had a thread on it recently, so a forum search may be useful.
 

FAQ: Voids inside atoms and voids in space?

1. What are voids inside atoms?

Voids inside atoms refer to the empty spaces or gaps within the electron cloud surrounding the nucleus of an atom. These voids are not completely empty, but rather contain a low probability of finding an electron.

2. How do voids inside atoms affect the properties of an element?

The presence of voids inside atoms can affect the reactivity and bonding properties of an element. The size and distribution of these voids can determine how easily an atom can bond with other atoms and form molecules.

3. Are there voids in space?

Yes, there are voids in space, also known as cosmic voids. These are vast regions in the universe that have a significantly lower density of galaxies and matter compared to the surrounding areas. They can range in size from a few million to billions of light-years across.

4. How are voids in space formed?

Voids in space are believed to have formed through the gravitational pull of dark matter, which causes matter to clump together in certain areas, leaving behind vast voids. Additionally, the expansion of the universe can also contribute to the formation of these voids.

5. Can voids in space be observed?

Yes, voids in space can be observed using telescopes and other astronomical instruments. The absence of galaxies and other matter in these regions creates a detectable contrast with the surrounding areas, making them visible to astronomers.
