Does light always travel at the speed of light? Light, no matter how high-or-low in energy, always moves at the speed of light, so long as it’s traveling through the vacuum of empty space. Nothing you do to your own motion or to the light’s motion will change that speed.
At what speed does light travel? Light from a moving source also travels at 300,000 km/sec (186,000 miles/sec).
What determines the speed light travels at? Einstein’s theory of special relativity unified energy, matter and the speed of light in a famous equation: E = mc^2. The equation describes the relationship between mass and energy — small amounts of mass (m) contain, or are made up of, an inherently enormous amount of energy (E).
Can anything go faster than the speed of light? Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. This speed limit makes it unlikely that humans will ever be able to send spacecraft to explore beyond our local area of the Milky Way.
