Reply to comment by EDFLsnape in The scariest picture of space... by EDFLsnape

From reading/watching material. They were discussing a solar telescope, using the sun's mass to act as a lense and see the light that gets bent around the sun. You could probably see things on planets in a detailed fashion. Then introduce the theory of a ship that is able to travel faster than light because space gets pulled through it.

Now combine the two, if you can travel faster than light without actually breaking the speed limit of light and have that telescope. Depending on where you place that device, you could see light before it reaches there.

This would make viewing actual history unfold since its the light of the past that the device would be getting ahead of.

You just broke causality and that's forbidden! The speed of light is not just a suggestion!

A hypothetical "Warp Drive" pulls space through it so you aren't moving faster than light, you are choosing how much space siphons through it to arrive at your destination.

Yes, but once there you could relay information, that information could then be acted on before light could have transmitted it. That's not actually a problem, but if another plus light speed trip took that information to certain places (as described on the Penrose diagram as in violation of causality) then they could use that information to, well I don't actually know, I believe in the speed of light!

Imagine sitting on a couch and decide to watch Italy 1521, but then got bored so you decide to switch to Feudal Japan 1190

Imagine someone in the future sitting on their couch watching you now.

Maybe, if their into watching someone bum around the house.

Just pass down instructions to, in the future, view a certain point in time when you're giving the finger.
