Is it at all possible for radio communication to travel from the obscured part of our galaxy to Earth? If so, about how long would it take to reach us? I have an idea for fiction where we're able to receive communications from the far side of the Milky Way, but we can't figure out how to communicate back, and the pursuit of trying to communicate back divides people and so forth. However if it's completely impossible in the realm of physics to receive communications from the far side of the galaxy, I'll have to rethink the idea. Note: I have little to no scientific background. Sorry, I'm working on it, though I have math-related disabilities.
