It may be plausible, just ask the Mythbusters...... hehehehehhehehe.....
You have to consider gravitations cause it effects and bends lights and also time.

wait... I'll drink first my Tequila.
How much is the time or the speed travel to Earth (including the distance), the information from Mars Rover or other man made satellites that traveling thru space? This is an exchange analogy from mirrors to radio waves.

It is not just plausible, it's a fact. 
And I think Jamie and Adam must already know it. But what I don't know is how far back in time will we see in that mirror if the mirror is placed exactly one light year away. I don't think the mythbusters can experiment that far?

your right gjabaigar, this is essentially the same as what happens in mars. When we get a radio signal back from mars, you could argue it is also from the past (albeit, a few seconds/ minutes, not sure on the exact time myself), because of the time it took to get the message to earth. Another way to put it if i gave someone a message to deliver personally to you, by the time it got to you, it would be "from the past"

If a mirror suddenly appeared, then yes, we could see the past, but sadly, it would take us too long to get out there and put a mirror up. Even if we moved at the speed of light (which we cant, not yet at any rate) we would just see a reflection of what was going on when the rocket or whatever left. But yes, we would see light rays from the past.
Look up at the night sky, you see those stars? Some of them dont even exist anymore! But the light they emitted (possibly hundreds of years ago) hasn't reached the earth yet, so we still see them.
To give you an example.
If i connected a wire from your house to my house, and lets say it takes an hour for me a basket with a message in it to be dropped (by gravity) along the wire and into your house. And i realse a basket every 20 mins. When i stop dropping baskets, you will still have 3 more baskets that you havent recieved (as they are still on the wire). In this anaogy, the baskets are the light photons, you are the earth, and i am the star!
Hope this helps

Exactly my point fpsninja 
Before this I was discussing about the possibility of creating a time machine and then this came up to me @melphens no, it's not connected to a parallel universe at all.

I posted a response similar to a question you earlier posted. I'd like to post it here as well. If you travel to space at the speed of light, time on Earth slows down. So if you were to leave Earth and travel at the speed of light for a few days and come home, people that you left behind would have aged significantly and you would be just the same age as the time you left them. So if your question is whether space time is equal to time on earth, answer is no. Hope this helps..

I am already at a lost on my question. LOL. Yeah but you are definitely right. I think it has something to do with gravity.

You do get into philosophical conundrums, don't you?! As you pointed out, we can only imagine. Wouldn't it be great if there were a way to prove these things?

No. While we're changing everything else is changing. If you're using a mirror and light to view far away objects you will just see what is there now. There is this misconception put out by so called scientists who don't even know what the word means that seeing things that far away could give us a glimpse of the past. This is not accurate. If you know how fast light travels (super duper pooper fast), then you would know that it can travel really far distances in a matter of less than a second. So the only thing you would see is right now. If you used another source, such as sound, through something like radar, then you might see the past. But it wouldn't be our past, just the past of the object you are viewing.

And mirrors increase the intensity of light, which speeds it up. So if it's a gigantic mirror like you said, then it would get here much faster. Especially if the mirror were large enough for us to see from earth. Then it would be instant.

Well if the mirror is set at a super duper pooper distance like a lightyear away then the light will reach it within a year and a year to see it back.

i don't know.i just want to live this time. wondering the past or the future makes me think that i am wasting time thinking about it. believe me i do think about it all the time.

are things different, but related, it's still an issue in which even the scientists themselves do not agree, you see on television programs and documentaries are always new scientists with different languages, and for ordinary people is quite difficult understand these issues.
