Yes, radio waves travel through the vacuum with the speed of light. BUT:Baad news bois, I'd very much like to see the aliens, but we will never meet them in hundreds of thousands of years. Why? I can explain this as follows: we have about 100 years of using and broadcasting radio signals throughout the earth, and these radio signals also broadcast in space at the speed of light. And those stars within 100 light years away can list our signals. And we still have not received any signals.
And we can safely apply this theory even further. We are here for about 4 billion years, and if an intelligible civilization is present within 4 billion light years, we should be able to capture their broadcasts, but none have been received. so we can safely conclude that there is no intelligent life within 4 billion light years away!
So, I believe it's our duty to spread life within the universe.
what if the radio signal frequencies we use cannot be heard by any other civilization other than earthlings?Baad news bois, I'd very much like to see the aliens, but we will never meet them in hundreds of thousands of years.

Yes, it's possible. But you know, if intelligible civilizations exist, they can filter out those frequencies and modify them to a comfortable level that they can hear. This was already done by human scientists, who captured the sounds of the universe and converted them into something that we can hear. We are a class 2 civilization, so if any other class 2 civilization exists, they can do the same.what if the radio signal frequencies we use cannot be heard by any other civilization other than earthlings?

What if they don't want to respond? Had you watched the 3 Body Problem, Netflix series, there's a reference to an Einstein Joke. Ye says it to Saul just before she leaves for China.what if the radio signal frequencies we use cannot be heard by any other civilization other than earthlings?

You might be correct. It reminds me of alert system in Mass Effect, where we have to be aware of Reapers (the enemy civilization, destroyer of planetary inhabitants). If we go far beyond safety limits of universe, reapers will begin to follow and attack us.The hidden meaning is if you advertise yourself in the Universe, there's the possibility that you get attacked. Alien races do not broadcast to advertise their position because they don't want others to find out where they are thus preventing any chances that they might get attacked.
