Did you ever see light from the Sun? Light is an electromagnetic wave, and it travels through a vacuum to reach us.
Light can travel through vacuum, but it is not a medium.
The sun rising every morning. Its' light traveled about 93,000,00 miles through a vacuum in order to be seen.If you accept that the space between the Earth and the Moon is lacking in atmosphere, that is, its a pretty good vacuum, then the simple fact that you can see the Moon (and Sun and Stars) is enough proof for me.
It travels faster in a vacuum.
You can see light waves (or particles . . .) but you cannot hear them. sound must travel thru matter , light can travel thru vacuum
Between the earth and the sun there is no air (its a vacuum). Sound cannot travel across a vacuum. Light can.

I can see the sun, the moon, and the stars.
I think they can, since that's how you see the sun and the stars.

Light does travel through a vacuum.
Yes ... in a vacuum.
No, light is at its fastest in a vacuum.
it travels at c (speed of light in a vacuum)
Light travels in vacuum but sound cannot. So, we can see solar flares but can't hear them. (Outer space can be considered to be vacuum)
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
