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.
Radiant energy is one of many types of energy, where energy is the ability to do work. Radiant energy is transferred in the form of electromagnetic waves, or waves composed of electrical and magnetic properties.ou see, outer space is void of matter. Therefore, the energy from the sun doesn't have anything to warm up. We feel the warmth of the sun as the sun's energy forces our body's molecules to move faster-in other words, work harder. Let's explore this concept in more detail.
