Yes, you're absolutely right. Einstein's theory was 'what if' but it is impossible to travel at the speed of light making the theory of time travel impossible. Impossible but mathematically plausible.

If we COULD travel faster than the speed of light, we SHOULD see into the past.

And yes chloe time is an illusion. or rather it's a measurement of an illusion, which opens a whole lot of new doors.
