This is the best explanation I've heard to answer this question. And it's fun!
Imagine a large clock. Light is bouncing off of that clock and racing toward your eyes at the speed of light. If you were moving away from that clock at the speed of light, the hands would never move, and time would stand still. If you were to go faster than the speed of light, you would catch up to the light that had left the clock in the past, and time would therefore appear to move backwards. Time, relative to your body and the universe, would not change, but time as a perception of your senses would reverse.

You wouldn't "peak" into the past - you'd actually go into the past. You would arrive before you left, which would lead to all sorts of possible paradoxes which is why physicists are pretty unified in their belief that this is physically not possible. Now certain experiments in quantum tunneling have allowed for transport across a barrier at greater than c (light speed in a vacuum), but the vast majority of physicists would say that although the effect makes it appear like particles "tunnel" faster than light, they actually don't and no information actually propagates the barrier at faster than c.

Actually in a way you are already looking into the past when you stare up at the sky. The light from the stars traveled hundreds of years ago, so you are seeing images from 100 or so years in the past!
You'd never be able to see the present time of a star unless you journeyed to it.

Peek maybe, but not to change the past.
Even if against all physics theories someone in the future could be able to alter the past ,such change would lead invariably to some weird casuality loop and we would be observing it's consequences right now.

I am sorry to hurt your feeling but you can’t travel faster than light with finite rest mass, but me since I care about you, I have discover a way of traveling back in time just for you my darling. All you need to do is close your eyes and remember your past. The speed is all up to your brain waves. go for it ,

You can't travel faster than the speed of light and you cannot see into the past. Can you imagine arriving somewhere before you see yourself leave for it ?

Theoretically yes. The light of a whole scenery will leave earth and if this scenery of light travelling outwards is not distorted and if we can leave earth faster than this scenery, we can then look back and see it coming.
Or if you move faster than the speed of light, and can look back and see yourself!
Lights from many stars have been moving towards earth. Some of them have been travelling for millions of years! and we can see them

If we were to travel faster than light we most likely wouldn't be able to go into the past due to whos past would we go to?? Many people have different pasts and we wouldn't be able to travel to everyone's past. Besides it would be a waste of TAX money.

In theory, yes you could. If you could arrive at a destination before the light got there, you could see what happened in the past.

NO. Because the past is the past already. You cannot peak into something which is not there or non-existince. Just remeber the past.. Enjoy it..
