So from an electromagnetic source, will the photons travel "forever" or will some of them "collapse" after a while ?

Yes, in a vacuum, light travels forever. This is because light does not experience friction or resistance, so it can continue to travel indefinitely.
There is no known limit to how far light can travel. However, the further light travels, the more it can be affected by factors such as gravitational pull and cosmic expansion.
In a vacuum, light travels at a constant speed of approximately 299,792,458 meters per second, which is equivalent to 670,616,629 miles per hour.
Light can be slowed down by passing through certain materials, such as water or glass. However, it cannot be sped up beyond its maximum speed in a vacuum.
As long as there is no obstruction or absorption, light will continue to travel indefinitely. However, it can be redirected or absorbed by objects in its path, causing it to stop or change direction.
