Here's why:
* Electromagnetic radiation is a type of energy that travels in the form of waves. These waves are made up of oscillating electric and magnetic fields.
* Unlike sound waves, which need a medium (like air or water) to travel, electromagnetic waves can travel through the vacuum of space.
* Examples of electromagnetic radiation: light, radio waves, microwaves, X-rays, and gamma rays.
So, while sound waves can't travel through space, light from the sun, radio signals from spacecraft, and other forms of electromagnetic radiation can reach us across the vast emptiness of space!
