You can see stars that are light-years away.
If you want to know the distance of the horizon, this will depend on the height of the spot where you are standing and your own height.
There's a calculator at: http://newton.ex.ac.uk/research/qsystems/people/sque/physics/horizon/
Yes there is. Your shadow is the simplest evidence that light travels in straight line. A solar eclipse is also evidence that light travels in straight lines, as is the fact that you cannot see around corners unless you use a mirror.
No. If you look far enough away, you will see OTHER objects in the past. For example, if a galaxy is ten million light-years away, the light of this galaxy took 10 million years to reach us, so we see this galaxy 10 million years ago. Earth's light, from millions of years ago, doesn't come back to us, since (roughly speaking) light travels in a straight line, and moves at the speed of light (300,000 km/sec).
You can see the horizon from any altitude on a plane. The horizon is the line where the sky meets the earth or sea, and it appears at eye level regardless of how high up you are.
The distance one can see ahead, known as line of sight, depends on factors like terrain, weather conditions, and visibility. On a clear day with no obstructions, a person with average eyesight can typically see objects several miles away. However, this distance can be limited by factors such as fog, rain, or obstacles in the environment.
because soem planets are to far away and our eyes cant see that far
A straight line in an organization chart is a line that is not broken up. When you see this, it means the person connected to the line is your superior.

You would expect to see tracks of animals like deer, rabbits, or foxes in a straight line in the snow.
a straight line which insect branches at the end and branches are parallel
If you draw a straight line on a piece of paper and place a protractor over it you will see the reading is 180 degrees. In this sense a straight angle is 180 degrees.
Because you can't see...

When your body is traveling in a straight line it wants to continue going in a straight line, but the coaster car is not traveling in a straight line and it pulls you down. See related link.

Minimum distance is 11,229 kilometers (6,979 miles) on a straight line. See, Cancun is in the Caribbean (North America), while Fiji is in Oceania, close to New Zealand.
A straight line that intersects a circle or curve at two points, but which has both end points outside the circle or curve is called a secant. A straight line that links two points on a circle or curve is called a chord. A straight line which touches a circle or curve at one point is called a tangent. A straight line that cuts a circle or curve at one point is a straight line.* For moving diagrams see Related links below this box.
depends on the person's eyesight and the amount of visibility
