This is the shortest time unit hypothetically possible to … WitrynaAnswer (1 of 36): It's a distance, but, it's what we call a relative distance. You see, a light year as measured on the top of a mountain, is slightly shorter than a light year as measured in the valley below. This might sound crazy, but it's true. You see, we no longer use cosmic time. We use a...

WitrynaA light year is a unit used to measure distance, not time. One light year is the distance travelled by light in one year. Light travels very quickly at around 300,000,000 … Because it includes the time-measurement word "year", the term light-year is sometimes misinterpreted as a unit of time. The light-year is most often used when expressing distances to stars and other distances on a galactic scale, especially in non-specialist contexts and popular science publications.

However, smaller units of length can similarly be formed usefully by multiplying units of time by the speed of light. For … Zobacz więcej
WitrynaA light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000kilomiters (km) each second. So in one year, it can travel about 10 trillion km. More p recisely, one light-year is equal to 9,500,000,000,000km light year a unit bassad on distance. Viktor T. Toth.
