In 'light years' or in 'scientific notation'
Longitude measures distances east or west on a map.
It is possible that someday astronomers will measure all the distances of the 100 billion galaxies in the universe.
Someday astronomers may have measured all the distances of 100 billion galaxies in the observable universe.
An increasing Hubble constant at great distances indicates an accelerated expansion of the universe. This phenomenon is attributed to dark energy, a mysterious force causing the universe to expand at an increasing rate. It suggests that as the universe expands, the distance between galaxies grows larger, leading to a greater Hubble constant at greater distances.
There are currently no known means to actually separate parts of the universe physically from the rest of the universe.
Yes, gravity is the dominant force over long distances in the universe. It is responsible for the structure of galaxies, the orbits of planets around stars, and the expansion of the universe itself.
Tables listing distances in kilometers are usually not used in the US because the US measures distances in miles, not in kilometers.
Any distances between two points outside the solar system, or betweenanything inside the solar system and anything outside it, are.(With the exception of the distances now being estimated between exoplanetsand their respective host-stars.)
It is an odometer.
The orbit and the roll lover cover.
It is a simpler way of measuring very long distances, which is what we have in the Universe.
Since we do not know the limits of our universe we cannot say for sure. As far as we can tell the universe goes off into infinite distances in every direction. We are at the centre of what we can see of the universe; but we have no way of knowing what part or how much of the total universe that is.
