Modern humans have been around for 200 thousand years. Our genus has been around for 2 million. The first agricultural city-states started to form 10,000 years ago; with writing around 6,000-7,000 years ago. Well, there may be a way around the exposure problem but I doubt it would be able to move in accordance with a planet over 1 million light years away. Who knows, if any intelligence ever builds such a device they will obviously be able to solve problems that we find incomprehensible.It's fascinating thinking that modern man has been around for two hundred million years, and written history/civilization extends to... what six thousand years ago?
Also, if you could build a telescope the size of a solar system, maybe it's possible that the telescope could move with the planet it's trying to get an exposure of?
