Any matter that does not produce or reflect photons of light that are between 750-380 nanometers in wavelength.
Or it could be dark matter which we still don't know what exactly is dark matter.
Although many people think they are in solid form or water vapor, clouds are actually liquid water. It's impossible for them to be water vapor, because vapor is invisible. Clouds are not invisible.
The black stuff in space is known as dark matter. It is a mysterious substance that does not emit, reflect, or interact with electromagnetic radiation, making it invisible to telescopes. Its presence is inferred through its gravitational effects on visible matter.
Carbon itself is not invisible, but carbon in various forms (such as graphite or charcoal) may appear dark or black in color, making it difficult to see against certain backgrounds. In its gaseous form as carbon dioxide, it is invisible to the human eye.
Air is a mixture of gases that is transparent to the human eye, which can make it appear invisible. However, air can be seen in certain conditions such as when it is filled with smoke, dust, or water vapor.
True, water vapor is an invisible gas formed when water evaporates. It is the gaseous state of water and is not visible to the naked eye.
matter must have mass and volume.though it may be visible or invisible.
Dark matter is invisible. It doesn't interact with light.
Dark matter is not visible to the naked eye and does not emit, absorb, or reflect light, so it does not have a color like visible matter. It remains invisible and undetectable through traditional telescopes, which is why it is called "dark" matter.
That matter was made of invisible particles
It depends what you mean by simplest. If you mean the smallest forms of matter, they are microscopic not invisible. If you mean basic components of matter such as quarks, atoms, molecules and so on, the answer is again that they are subatomic to microscopic in size and so not able to be seen without aid, yet not invisible. The only things that are truly invisible neither absorb nor scatter light, and therefore we can not see them in the visible light spectrum, like dark matter.
Gas can sometimes be visible with the example of smoke from a cigarette but it is also invisible as in the case of carbon monoxide which could not be seen or smelled.
Gas is typically invisible because its molecules are spread out and move freely, allowing light to pass through without significant distortion or absorption. This is why we cannot see gases like air or oxygen with the naked eye.
A good example of visible energy is found in the stars. An example of invisible matter is the "dark matter" that scientists believe surrounds galaxies. So, one answer to the question would be "in and around galaxies".
The right answer is dark matter. Air has particles that can interact eletromagnetically, so it is not invisible. Dark matter, to this day, is known for it's great gravitional attraction and it's capability of not interacting with photons.
Plasma. It makes up more than 99% of visible matter in the universe, and most of the invisible matter.
No Matter What Hair Type, Theirs Different Methods For Invisible Parts. Check YouTube.
The chair is primarily composed of visible matter, such as wood or metal. The invisible components would include the space between atoms and any energy associated with the chair, like electromagnetic fields. The ratio of stuff (visible matter) to non-stuff (invisible components) in the chair would be predominantly skewed towards the visible matter, with only a small fraction being the invisible components.
