1965, Moscow Unusual radio transmissions from space were intercepted by Soviet astronomers. Professor Loserf S. Shklovsky of the Sternberg Astronomical Institute expressed cautious hope, saying that it constituted “…an totally new, yet unknown sort of cosmic object…” at the very least.
From Cornell University, the knowledgeable Dr. Frank Drake (well known for his work on SETI and his eponymous equation) weighed in. He argued that any number of variable stars or other quasi-stellar radio sources may have contributed to the Russians’ discovery of an ordered pattern.
The difficulty remains that radio waves move much too slowly in the expanse of space, as it does in any of these situations. Any culture that sent such a message would most certainly perish before it was received by another civilization, which is why science fiction programmed like Star Trek have to create a fictional’subspace’ to communicate across the galaxy.
If such intergalactic aliens exist, it would seem that they would have to communicate in a way other than radio. It’s possible that communication takes place between dimensions or at the quantum level, where the laws of physics as we know them seem to take a break.
