How can radio waves travel through space?

Radio waves are light waves with a very low frequency and high wavelength. They are mainly used for communication because they can travel long distances without too much interference or disruption.

As far as we know, light does not require a medium to move around, we used to think it was "ether", but that was proved wrong by the michelson-morley experiment, you can look that up in your own time.

There is. Electromagnetic energy is an electric field perpendicular to a magnetic field propagating through a medium at a right angle to the directions of the electric and magnetic fields. That's why radio waves and visible light waves can propagate through a vacuum and an an atmosphere and through glass. while sound waves CANNOT, becauase sound waves are longitudinal PRESSURE waves that require a medium.

Rado waves are Electro Magnetic and not particles. They can travel freely in a vacuum.

There should be.

Science does not have a definitive answer.

Light and all electromagnetic (EM) radiation displays two apparently separate characteristics.

It has a wave nature

and

it has a particle nature

This article discusses both of those, and other aspects of EM radiation. :
