Radio waves are pathetically slow (and weak) and transferring information at light-speed would still take years.
The fact remains that until we discover some kind of a MIRACLE way to completely bypass light's restrictive snail-paced speeds (wormholes or whatever), mankind won't even be able to take a true photo of our own galaxy from the outside. The Milky Way is approx 1K lightyears thick and 100K lightyears wide, our race would have to survive for several millennia to develop such technologies and reach such distances - and for what reason exactly? Pointless
This is true. Communication back to Earth is the main thing. Cryogenics are probably our best hope in reaching another planet that can sustain human life. Earth would be gone for thousands of years even if we could get close to light speed, or millions of years if we couldn't. It's not pointless
What if your brain memories could be scanned with this: http://www.extremetech.com/extreme/123485-mit-discovers-the-location-of-memories-individual-neurons
Your body could be re-grown in a tank and your old memories encoded into a blank-slate mind
Or everyone who can afford it is sent into a ship with cryogenics like pandorum: http://www.youtube.com/watch?v=yMEhkTxs3_E
By the way, have you all heard of Kepler 22-b? It's a few months old news, but I was excited when I first heard about it. It's a planet in the "habitable zone". Meaning it could sustain life.
