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.
That's something I never understood. Why is it that this one prominent energy, light, is the mark for what speed nobody can achieve? Also I was under the impression that travelling at a faster velocity at a far away point in space would cause a minor time differential. For instance, I remember hearing about this Russian astronnaught who was in space for 8 months, and they said that according to relativity he would have come back about 5 minutes younger than the point he would have aged to had he spent that time on earth.
