Would this work?

If were to fly out into space 1 light year away and set up a giant mirror facing earth, then looked at said mirror through a high power telescope, would we be observing everything on earth 2 years in the past?

Theoretically I don't think it's even possible to do such a thing, the mirror would have to be too big and the telescope beyond anything we're capable of doing.
But in theory, yes, that's what would happen.

if you were 1 light year away i doubt you would want anything to do with looking back on earth.
some brain food though.

It would be one year in the past. The light traveling with you at lightspeed would be the light you started with on Earth. So you wouldn't miss a thing technically. You could watch everything.

Wouldn't it take 1 year for the light from earth to hit the mirror then another year for it to bounce back to the telescope back on earth?

If light is travelling in a straight line back and forth then who's to say which direction it's travelling?

I'm saying theoretically I don't think it's even possible to do, no matter how advanced we get. But as far as theory of light travel goes, yes you would expect to be looking back 2 years into the past.

If you shine two identical flashlights directly at eachother how do you know which light is which? I mean, is the light from each flashlight bouncing off the glass and returning to the flashlight, are the sources creating an individual and identifiable light source, or can you look at the middle and just say "Yeah there's some light there"?

I get what your saying, but its different if you're actually viewing the light and there is only one light source.

If you look into a mirror, what you are actually seeing is the light reflecting off that mirror and it takes time for the light to bounce off you, hit the mirror and bounce back off into your eyes. So theoretically every time you see yourself in the mirror you are actually seeing yourself in the past, even if it is 0.00000001 milliseconds in the past.

 How about this. If both torches are turned on at the same time, one path is direct but the other is bounced off mirrors, will both people see the light at the same time? If the speed of light is 299 792 458 metre per second, then increasing the distance the light needs to travel will delay its arrival at its destination correct? I'm not the best at getting what's in my head into words but if you can manipulate light is that not manipulating time? Ie. If you slow down light you are slowing down time.

That would take you 39,000 years to get there in a shuttle (not counting how long it would take to refuel to fight the effects of the sun's gravity, bathroom stops, and not subtracting how much less time it would take if you slingshotted around planets to increase your speed, and pee'd out the ship's window instead of stopping).

wolfiewolfie said: and set up a giant mirror facing earth
How big of a mirror? Did you bring it with you, or do you need to take more time to mine planets for materials? Do you have to spend additional time battling a war because you tried illegally mining a planet with life forms already on it who are pissed that you're taking their aluminium for a giant space mirror?
Quote:
wolfiewolfie said: then looked at said mirror through a high power telescope
Who looked through the telescope? Did you look through it towards Earth from where you built the mirror? Or are we looking at you and your mirror 1LY away? Or did you take another +39,000 years to get back to Earth to look through a telescope at your mirror 1LY away?
Quote:
wolfiewolfie said: would we be observing everything on earth 2 years in the past?
-No.- I don't know what your species' life span is, but mine is only 300 years, so I'd be dead by the time you set this whole thing up. Kinda a waste of time, if you ask me. I'm going back inside, it's getting cold.

No. The light having to do more bouncing would take longer to reach it's intended target since it's a longer distance.

Arctic you are correct in everything you say, however you are focusing on unimportant areas of my question. Firstly lets just say that 'somehow' the mirror was set up 1 light year away. We are back on earth looking into the mirror through a telescope. The light that bounces off earth would take 1 yr to to hit the mirror, then another year to bounce back to our telescope therefore the light we would be observing is light that bounced off the earth 2 years ago. And seeing as all we see is light, we would be seeing the earth through a telescope 2 years in the past. As for the torches, you agree that if we slow down light by making it have to cover more area we can make an observer view something at a different time to someone else, therefore manipulating time?

This is hands down, the least scientifically thought out hypothesis I've ever heard. And someone once told me LSD can transfer to her pet cat through skin contact...

I'm just initiating a healthy debate over an idea I had after a few bowls. Sorry if that offends you
