Hi,
I read the following on seti.org:
"Our earliest TV broadcasts have reached several thousand nearby stars, although any alien viewers would have to build a very large antenna (thousands of acres in size) to detect them."
I guess that signals have got very weak...( does it mean amplitude is very small that it was when it was transmitted?)...but what difference is the size of antenna going to make?
