How do you explain how light can travel through the vacuum of space?

Newtons 1st law, "An object in motion will stay in motion unless acted upon by another force." Basicly the photons travel through space gradually spreading out as they hit different particles.

What is an empty space that contains no matter that light can travel through?
A vacuum.
In a perfect vacuum, light waves travel at 300,000 kilometers every second. When light waves travel through materials, such as air, they?
slow down.
The speed of light indicates how fast light can travel in a vacuum?
Yes ... in a vacuum.
What do light waves travel best through?
Light waves travel fastest through vacuum, at nearly 30 million meters per second. Light travels more slowly through other substances such as air and water, and can be absorbed.
What type of wave does not need a medium to travel through?
It is electromagnetic radiation that needs no medium to travel in. Gamma rays, light and radio waves, all forms of electromagnetic radiation, can travel through the vacuum of space very well. In fact, they prefer it.
Why doesn't light travel through a vacuum?
Light does travel through a vacuum.
Can gases travel through a vacuum?
No. Only light waves can travel through a vacuum.
Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.
What can light travel through that sound cant travel through?
light can travel through a vacuum whereas sound cant
Is light an example of mechanical wave?
No. Light is an example of an electromagnetic wave, which can travel through a vacuum. Mechanical waves must travel through a medium, and cannot travel through a vacuum.
Does light travel at its slowest speed when passing through a vacuum?
No, light is at its fastest in a vacuum.
What evidence do we have that light travel through a vacuum?
You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.
What does light travel faster through?
Light travels fastest through vacuum.
Can polarized light travel through a vacuum?
Why not? Of course it can!
What will light travel through that sound won't?
A vacuum.
Can light and sound travel through vacuum?
Light can. Sound can't.
Will a light wave travel through a vacuum?
Yes. Electromagnetic waves (including light as a special case) are, in fact, the only type of wave which will travel through a vacuum.
