Ive been looking at the E = mc2 explained on youtube and apparently light has no mass how can it have no mass but you you can feel heat on your skin from light

Light is made up of particles called photons, which have both wave-like and particle-like properties. These particles do not have any rest mass, meaning they do not have any mass when they are not moving. Therefore, light itself does not have any mass.
While most objects that we encounter in our daily lives have mass, there are certain particles, like photons, that do not have any mass. This is because they travel at the speed of light, which is the maximum speed allowed in our universe. According to Einstein's theory of relativity, objects that travel at the speed of light do not experience time or have a rest mass.
Even though light itself does not have any mass, it does have energy. This energy is what allows light to interact with matter, such as causing objects to heat up or creating chemical reactions. When light is absorbed by matter, its energy is transferred to the particles of the matter, causing them to vibrate or move.
While light does not have any mass in its natural state, it is possible for light to gain mass under certain conditions. In theory, if light were to slow down or be confined to a small space, it could gain a small amount of mass. However, these conditions are not possible in our universe, so in practical terms, light does not have mass.
The fact that light has no mass has significant implications in the field of physics. It has led to the development of theories such as quantum mechanics and the theory of relativity. Understanding the properties of light has also allowed scientists to make groundbreaking discoveries in areas such as optics and the behavior of electromagnetic waves.
