if light is a transverse wave, wouldn’t it need to travel trough gas through the whole length of the journey? I thought that there was no (or very little) gas in space, or am I just thinking of oxygen?
light is an electric magnetic wave. a change in electric volts causes a magnetic force and a change in magnetic force casuses an electric voltages thus the piggy back off each other the be able to travel through a vacume References :
Space is a complete vacuum, there is no classical medium that light (or any electromagnetic waves) can travel through, but that is okay, because electromagnetic waves travel through space without it needing a classical medium.
The only medium that light needs to travel in is space itself. References :
Light does not need a medium through which to travel.
It propagates through vacuum just as easily as through air
or water or any other transparent environment. References :
Light does not need a gas to travel through, in fact, it travels faster in perfect vacuum than anywhere else. Convection requires lots of matter, allowing heat to travel in abundance to Earth. Also, there was a belief in the 1800s that everything was immersed in aether, which allowed light to travel freely.
Light travels light. That’s how it gets here so fast. References :
Light behaves like both a wave and a particle. If you prefer, think of light as small, massless photons traveling through the vacuum of space. References :

no, light does not need a medium in order to transfer, because light is made up of particles but not vibration as sound.

WOW!
Education certainly isn’t what it once was!
You should file a lawsuit against your local school system.

It’s a wave through electromagnetic field.

it just goes through the space i meean the ozone layer then reaches the earth’s surface
