Empty Space that contains no matter. Light can travel throught this?

Question

what word is it?

Answer 1

I think you're referring to a vacuum. I believe that light can pass through them, but that sound can't.

Answer 2

This is a better question than I bet even you thought. This is because we can never know if light can travel through the vacuum of space with no matter in it. Where would it originate? And, in order to see it, we would necessarily have to be there.
Kind of like the ol' "If a tree falls in the forest......."

Answer 3

Light travels through space because it does not need matter to travel in the first place. Whenever an electric charge (such as a proton or electron) "shakes" it produces an electromagnetic wave known to us as light. When the electric charge shakes it creates a magnetic field, which then creates an electric field, which creates another magnetic field, and so on so forth. Electromagnetic waves function with magnetic and electric fields, therefore not needing matter at all to travel.

Answer 4

Good question. This puzzled physicists for years until they figured out that light is both a particle AND a wave. Particles can travel in a vacuum. What is weird is that light also exhibits wave like properties in a vacuum

Answer 5

This shows that light is not a matter.
Another view is that there is no empty space; and light will be passing through it.

One more view is that empty space is one in which no matter is present except light.

Answer 6

So called empty space or the "vacuum" is really a physical field. It is not empty or a vacuum. There is no such thing as a pure vacuum.

Answer 7

Er.... the vacuum?
