When something is described as say 7 billion light years away would't it be more accurate to 7 billoin years ago?
Not if spelling counts.Simon Peach said:When something is described as say 7 billion light years away would't it be more accurate to 7 billoin years ago?
Why bother? What's wrong w/ 7 billions light years away?Simon Peach said:When something is described as say 7 billion light years away would't it be more accurate to 7 billoin years ago?
It is ambiguous in its very purpose.Simon Peach said:When something is described as say 7 billion light years away would't it be more accurate to 7 billoin years ago?
A light year is a unit of distanceSimon Peach said:When something is described as say 7 billion light years away would't it be more accurate to 7 billoin years ago?
7 billion is a long time. Long enough that cosmological corrections are required.Simon Peach said:When something is described as say 7 billion light years away would't it be more accurate to 7 billoin years ago?
Definitely no.Simon Peach said:When something is described as say 7 billion light years away would't it be more accurate to 7 billoin years ago?
A light year is a unit of measurement used to describe distance in space. It represents the distance that light travels in one year, which is approximately 9.46 trillion kilometers.
The term "light year" is used because the distance that light travels in one year is a significant and convenient measure for the vast distances in space. It allows scientists to describe and compare distances that are too large to be measured in kilometers or miles.
Yes, the term "light year" is accurate for measuring distance in space. It is a unit of measurement that is widely accepted and used by scientists and astronomers.
No, a light year is a unit of distance, not time. It represents the distance that light travels in one year, not the time it takes for light to travel that distance.
Scientists use light years to measure the distance of objects in space, such as stars, galaxies, and other celestial bodies. It also helps them understand the scale and size of the universe and how objects move and interact with each other in space.
