Does light continue to travel through space after its source is removed?
Fortunately for astronomers, it does.k9b4 said:Does light continue to travel through space after its source is removed?
And it gives a wave as it goes past.NascentOxygen said:Yet it does reflect.
thetexan said:In fact you can actually watch this in action. Believe it or not they created a camera that can film pulses of light.

Light is a form of electromagnetic radiation that can travel through a vacuum. It is made up of particles called photons, which have both wave-like and particle-like properties. Light travels in a straight line at a constant speed of approximately 299,792,458 meters per second in a vacuum.
Yes, light will continue to travel through space after its source is removed. This is because light is made up of photons, which have energy and momentum. Once emitted, these photons will continue to travel until they are absorbed or interact with other particles.
Light can travel indefinitely in space, as there is no medium to slow it down or absorb it. However, the intensity and direction of light may change as it encounters different objects or particles in space, such as planets, stars, or interstellar gas and dust.
Yes, light can be affected by gravity and other forces in space. According to Einstein's theory of general relativity, gravity can bend the path of light, causing it to appear to be deflected when passing near massive objects. Light can also be affected by other forces such as magnetic fields or radiation pressure from stars.
The distance of an object from Earth affects the light we see in two ways. Firstly, the farther away an object is, the longer it takes for light to reach us. This means that we see objects as they were in the past, as light from distant objects takes time to travel to Earth. Secondly, the intensity of light decreases with distance, so objects that are farther away appear dimmer to us.
