Traveling faster than the speed of light means you get somewhere faster than light, not a reverse in time.

Think on it this way, if indeed we were somehow able to launch a probe capable of reaching another star with in say 50-100 years(journey time). From our perspective here on Earth the probe would seem to take rather more than 50-100 years to reach its intended target.

If your ship had headlights on and you were travelling at the speed of light, you wouldn't see any light emitted by those headlights. If your speed would be even slightly slower than speed of light, you would see the lights, but it takes forever to see the actual light.
And if you teleported on planet that is 50 light years from us, you would see Earth as it was 50 years ago. If you teleport far enough, you would see the dinosaurs.
Simple answer if you could make a trip faster than light yes. Lets say i travelled out 120 light years id be listening to the start of radio listening to their commercials and radio shows. In effect i went back in time to listen to the broadcasts

Interesting concept. Say we had wormhole tech, open a wormhole next to earth with the exit say 100 million light years away. Send a telescope through and have it look at our solar system while instantly sending info back through the wormhole. Voila! Front seat tickets on the creation of the earth.

I've read replies and I will add my own. In short to the post heading no, firstly you can't travel faster then light. But let's assume a thousand lights years away (relatively close) could you use a very very very powerful telescope and view things happening on the surface of a planet, it would be a thousand years in the past. Problem is I personally don't think you would be able to because light wouldn't carry so precise an image over such a distance.
It wld take like a planet size telescope in dead of space with a clear vision of the target. plus you wld be looking at the past of some planet not yours.
even now planets aren't seen they are mostly infurred.
Instantanious travel, then yeah it probably can happen. But instantanious travel is pretty damn doubtful
Yes the reflection concept is a nice theoretical way to look into the past without having to exceed light speed, but whether you used that or flew a telescope faster than light away from Earth, we don't have the technology to see very much detail.

I'll go one better- if you could do a cosmic-scale kind of femto photography and had adequate computing power to account for what light was coming from where, perhaps you could take a picture of the reflection of our own history on a distant body without traveling faster than light.

We can't even aim a telescope at the moon and get a good view of the Apollo landing sites. Can you imagine how bad the resolution would be light years away? Using a mirror would double the effective distance.
