The universe is made up of matter and energy. Matter â anything that has mass and takes up space â is pretty straightforward and easy to grasp, but energy is a bit more abstract. In physics, energy is the ability to do work, or the ability to move or elicit change in matter.
Electromagnetic Energy. Electromagnetic energy is an invisible form of energy in the transverse wave form. Of the many types of energy in our universe, this form of energy is the only one that does not require a medium or matter to travel on or in. This form of energy can travel through empty space as a transverse wave.
