Perhaps time travel into the past isn't really "possible", or at least in a weird way undiscovered at current. But, we can probably get a glimpse into the past. For example, our star, the Sun, is about 8 light minutes away from us, wherein it takes about 8 minutes for the light from it to reach us. If it went out, we wouldn't know for 8 minutes (iirc). Likewise, stars from afar are showing us their "past" relative to our "present". If, in some way, we could travel really fast and really far to a faraway star area, we would have traveled faster than the time it takes the light from Earth to reach that area, and then we could glimpse into Earth's past. Of course, this requires a speed of travel really fast, like a Tachyon, and is probably impossible, but it is an interesting conjecture to think about.
