Light is both like a wave and like a particle. Particles don't need anything through which to travel; in fact, you might expect particles to travel better when there's nothing for them to interact with. Light is like that, too. Light travels faster in a vacuum than through any material as packets of pure energy (photons).
Yes, light can travel in space. Light is an electromagnetic wave, and it doesn't need a medium to travel through. A medium is matter that mechanical waves use to travel. And of course, the sun is in space, and the light from it gets to us. In fact, it takes about 7 to 8 minutes for it to get here from the sun.
Light is an electromagnetic radiation and, like all such radiation, it consists of electromagnetic waves. These are synchronised oscillations of electric and magnetic fields which propagate at the speed of light through a vacuum. The oscillations of the two fields are perpendicular to each other and also perpendicular to the direction of energy and wave propagation, forming transverse waves.
it can travel through beams or rays like lasers
Electromagnetic energy
PS: What does this have to do with religion and spirituality?
it can travel throuh space at a speed of 186,000 miles per second
Light travels fastest through empty space.

It doesn't travel faster through a vacuum. In our Universe there is no such thing as empty space.
Yes.
A type of wave that can travel through empty space as well as through matter is electromagnetic wave. Light travels fastest in empty spaces.
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
Light waves can travel through empty space. You might say that the empty space is the medium in this case.
A vacuum.
sound cannot travel through empty space.
because there is nothing in space to block the light and no barometric pressure
Sound waves cannot travel through empty space because they require air particles to transfer them. UV is a light wavelength and can travel through space (just like light from the Sun reaches the planets).
No, there can't be conduction in empty space. Heat may travel through empty space through radiation, though.
