So lets say you have a telescope, binoculars, microscope, w/e. Light enters and gets refracted, reflected a couple of times or whatever. Now lets say you have thousands of micro mirrors perfectly aligned so that it causes the rays of light to bounce around for about 15 minutes. After they finally finish bouncing off mirrors in the device, it now exits the device. If you looked at it at this time you would see 15 minutes into the past right.

Yes, but who wants to look into the past? You should look to the futur

how about this: you record everything on video and watch it 15 mins later. there, looking into the past.

in this hypothetical telescope that can see 15 mins into the past... I wonder If I can blind my 15 min past-self using a laser pointer?

Keep in mind it would only see 15 minutes into it's past. (ie. you wouldn't be able to point it somewhere and see what happened there 15 minutes ago). It is effectively some retarded video (no audio) only replay device.
well yeah but this would be pointless as you would only see the 15 minutes past of what you was looking at so you wouldnt notice anyway, intresting video on youtube about quantum physics summin like "quantum physics for beginners" i think its rather intresting lol *cough* geek lmao

what if you were to use materials with negative index of refraction, would you then be able to see into the future?? It is a mystery...
That being said, 15*60*3e8 = 2.7e11 meters. That's 270,000,000,000 meters, or 167 million miles. To accomplish this task with mirrors, you'd need to align them so as to set up a path 167 million miles long. That's a long ass distance to get light to travel with mirrors. The light would probably fall out of alignment simply by the rotation of the earth.
So the Sun is 8 light years away from Earth? That means the Earth's orbit would cover 16(pi) light years. I didn't know the Earth was traveling over at 50x the speed of light.

the sun cant be that far away it wouldnt even be that warm its only a couple miles away from the earth and it orbits the earth not the other way around modern science is wrong its all liez liez liezzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
Oh dear... you people have failed simple physics... I fear that the sun is aproxamatly 149600000 km, meaning it takes 8 minutes NOT years for the light to reach us.... with the speed of light being 299,792,458 metres per second through a vaccum.
And it's warm because it's surface temprature is 5785 Kelvin (that's 8520 *C). Though intrestingly you'd freeze to eath not burst into flames if you were thrown out of an air-lock... No I don't understand that one either... it's somthing to do with the fact your still in a vaccum.

That was a much less funny way of making a point than >>24. Spelling out things like this when the discussion is already over just makes you look like the ass you are.
And when you get thrown out of an air-lock, you die of suffocation. It takes much longer for you to freeze in space than to freeze at the north pole because there's no low-temperature medium to interact with to draw the heat. You cool only by blackbody radiation.
