- The question of how light travels through space is one of the perennial mysteries of physics. In modern explanations, it is a wave phenomenon that doesn't need a medium through which to propagate. According to quantum theory, it also behaves as a collection of particles under certain circumstances.

May 19, 2016 · Basically, traveling at incredible speeds (299 792 458 m/s) and at different wavelengths, depending on its energy. It also behaves as both a wave and a particle, able to propagate...
Oct 29, 2024 · It's one way that astronomers and physicists measure immense distances across our universe. Light travels from the moon to our eyes in about 1 second, which means the moon is...
Jul 16, 2020 · Ergo, light is made of electromagnetic waves and it travels at that speed, because that is exactly how quickly waves of electricity and magnetism travel through space.
As the light from the universe’s most distant galaxies travels through space, it’s stretched by the expansion of space. By the time the light reaches Earth, that stretching process has transformed short wavelengths of visible and ultraviolet light into the longer wavelengths of infrared light.
Jan 23, 2024 · The speed of light is 299,792,458 meters per second and that constant tells us much about cause and effect in the universe.
May 16, 2007 · How Does Light Travel Through Space to Earth? How do the rays of light come to Earth? We're not sure exactly what you're asking, but this page at Imagine the Universe! covers light in terms of the visible spectrum and our eyes, and how light travels in the vacuum of space.
Hubble works by gathering light from objects in our universe – some as close as our Moon, and some as distant as galaxy clusters that are billions of light-years away. All that light takes time to reach the telescope, just as it takes time for light to travel from its source to our eyes.
