The speed of light is absolute, so you begin there. You know the distance between the Earth and the sun (from celestial mechanics originally), so now you have a general idea of how long it takes for light from such an object to get to to your eyes.
Now you've spotted an object - a star, or distant galaxy, let's say - and ask how far away it is. You compare its light to that of objects (like the sun) that you know. A little math tells you that what you're seeing happened there a billion years ago.

Were the aged crown there comet wisdom in the story of aged mother?
Yes, in the story of "The Aged Mother" wisdom is portrayed through the aged mother's experiences, teachings, and selflessness. The aged mother imparts valuable lessons about love, sacrifice, and nature, highlighting the deep wisdom that comes with age and experience.
Is time faster than he speed of light?
This is an unanswerable question, since time is a dimension and the speed of light a measurement. The two are directly related, however, insofar as approaching the speed of light inversely affects the relative speed with which you travel through time. For instance, one year on a spaceship going 99% the speed of light (it is impossible to reach the speed of light relative to local space-time, in that paradoxical scenario time would stop completely) would cause you to return to an Earth that has aged hundreds or possibly thousands of years (I'm not sure the precise speed to time conversion formula).
What does relative dating depend on to identify similarly aged rocks in different locations?
Relative dating depends on principles such as superposition, cross-cutting relationships, and fossil succession. These principles help geologists determine the relative ages of rocks by comparing their positions and relationships to each other.
What removes aged and defective red blood cells?
The spleen is responsible for removing aged and defective red blood cells from circulation. These old cells are broken down by macrophages within the spleen and recycled for the production of new red blood cells.
How old it was Isaac Asimov when he died?
April 6, 1992(1992-04-06) (aged 72)
How do we find the center of gravity of a given aged?
You can use plumb lines to find the center of gravity of an object.
What color are middle aged stars?
Middle aged stars, like our Sun, appear yellow in color. This is due to their surface temperature and the way in which their light output is distributed across the visible spectrum.
Why is your Sun considered unusual?
its middle aged , and its absolute magitude is about average. it shines with a yellow light.
Is cognac more red or brown?
More brown, since oak is brown, and that's what it's aged in.
Can you mix tequila with milk?
It's best with light rum, but I've done it with aged rum and it was doable.
What is aged travel insurance?
Aged travel insurance is very similar to regular travel insurance. But you would not need to pay as much for the aged travel insurance since it takes into consideration that older people tend to develop more health complications than younger people do.
Why can't the tucks in any one place for very long?
They couldn't stay for very long because they never aged. Since they never aged, people would eventually get suspicious and start to wonder about them.
What was Thomas Edison's second invention?
In 1915, aged 68, he invented the first synthetic form of carbolic acid (C6H6O). He died in 1931, aged 84, in New Jersey, USA.
What has changed with a hammer since the stone age?

What was Robert E. Lee's hair color?
As a young man, it was dark brown. As he aged, it turned light gray.
If you travel at speed of light to another planet will people age more than you when you get back?
According to Einstein's theory of special relativity, this is correct. His theory states that relative velocities correspond to differences in time. In simple terms, a "faster" moving object's clock will tick slower than a stationary object's clock. Thus, if one were traveling at close to light speed (one cannot travel exactly at light speed) to another planet, upon his return he will have aged less than those people who remained stationary, with respect to his motion.
If Peter Pan aged how old would he have been?
No one knows, that's the point, he has been in never land for as long as he can remember, and since has never aged. Therefore no one knows and probably wont ever know.
