Live as a digital copy, travel at the speed of light.

Yes! This could work! Lots of ancient literature refers to something similar so the idea has been there for millennia.

The catch is that the receiver has to be sent out first. And what difference does 'where' make when digital?

Tiny light sail spacecraft don't need new physics.

People have talked about going to 0.1 c and to another star that way, but rather if you can send a large number of those past 500 a.u. you can use the Sun's gravitational lens to image continents on planets in other solar systems, watch stars get wrecked by a black hole, and watch other civilization's TV programs.

That same kind of telescope is how you get downlink from the interstellar filmcraft.
