Is sound and light made up of matter?
Sound cannot be matter as we can not see sound and it has no mass or volume.
Helps us understand something that we cannot see directly?
A Model
What is something in motion that you cannot see moving?
Moving air or wind is difficult to see. The motion of atoms can not bee seen with the unaided eye. One can not see the motion of tectonic plates. In these examples, the phenomena are not visible but one can measure them.
When do you say that something is a matter?
You say that something is a matter when there is mass and occupies space.
Things with what cannot share the same space at the same time?
Matter refers to something that takes up space. One of the ways that matter operates is that no two things can occupy the same space at the same time.
Can matter be something you cannot see explain?
Yes, matter can be something that you can not see. This is because one form of matter is gas, which can not be seen.
Can matter be reycled?
No, because matter is something that takes up spaces, and matter is something that you cant see.
Is sound example of matter?
Sound cannot be Matter as we can not see sound and it has no mass
Why energy is not a form of matter?
matter is something you can see or touch energy is not.
What is something that is matter?
Air is Matter Everything is Matter because you can fill it and also see it.
Is steam a matter?
Yes, true steam (you cannot see it) is matter in the gas form.
Does anyone no if you have proof dark matter exists?
The clear answer is, we don't. We cannot detect the hypothetical "dark matter", and the only reason we are talking about "dark matter" is that we cannot actually see enough mass in the Milky Way galaxy to account for the gravity that we know must be there - because the Milky Way would fly apart with only the mass that we can see. The "dark matter" may be in the form of invisibly-dim brown dwarf stars, or black holes, or "something else". Dark matter is the "something else". Everything you read about dark matter is a guess.
Matter that is all around you that you cannot see?
The air.
What is invisible matter?
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.
What is something that has weight but you cannot see?
microrganisms
Is sound and light made up of matter?
Sound cannot be matter as we can not see sound and it has no mass or volume.
How do atronomers detect dark matter?
Gravity. We cannot see or directly detect "dark matter", and the only reason why astronomers talk about "dark matter" is that galaxies like the Milky Way appear to be spinning too fast for gravity to hold them together. Or at least, for the gravity of the mass that we can SEE to hold them together. Gravity comes from matter, and we can't see enough matter, so it must be "dark matter". This may be in the form of trillions of invisibly-dim brown dwarf stars, or in black holes from which no light ever escapes - or it may be something entirely new. "Dark matter" is the something new.
