It couldn't bring a person to the event itself, only to a view of what it was at the time of occurrance.

I'm thinking of hiring an access platform so I can see the height of the high horses that will be seen here.

I'm certain the idea is used to suggest time travel is possible, if it is then the ends of light rays are a different matter.

This can go to vote, I really want to delete it though. No one has answered what I asked.

"It couldn't bring a person to the event itself, only to a view of what it was at the time of occurrence"
This is true for an event at ANY distance. Think about it. An event happens five feet in front of you. When the light from the event reaches you, you are not seeing the event as it happens. You are seeing it with a delay equal to the time it took light to travel those five feet.
You are never actually at any event. You're always some non-zero distance away, and you will therefore never see an event as it actually happens.
Being hundreds of light-years away just means you're seeing events with a delay of hundreds of years, as opposed to a few picoseconds.

Learning how the universe formed is very important to us and looking at the farthest points of light we see things that have been gone for millions of years. What we are seeing is light from the earliest age of the universe. Astronomers like referring to this as time travel back in time and the effect is to give us a look at the early forming universe as it was. Edwin Hubble sought to understand the origins of the universe and now after his death, we are able to go back in time using the space telescope named after him.
We can also see what the universe a million light years away looks like today but with current technology we have to wait a million years for todays light to reach us. Maybe they will come up with a way to do that some day.
Time is a dimension and according to Einstein, we are all traveling.

It is simple. Time is not a dimension and you can't travel in it.
There will always be people who present a paradox or fallacy, to confuse reasoning, before asserting that time travel is possible.
You can never see the end of the ray that is travelling away from you. The suggestion is that you somehow can.

I'm not sure what you mean. If you are asking why we can't view things any sooner than light takes to travel from the event to us, then that's because the speed of light appears to be an absolute limit on how fast energy can be moved.

If I understand your question, it's because light takes time to travel from place to place.At 300,000 k/ps light is pretty fast.
However it is not instantaneuos.So...every thing you see is actually historical data.
