How fast do radio waves travel through space?
Actually, radio waves travel very quickly through space. Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light. The speed of light is a little less than 300,000 km per second. At that speed, a beam of light could go around the Earth at the equator more then 7 times in a second.
Why does it take so long for radio messages to travel?
The reason that it takes so long for radio messages to travel in space is that space is mind-bogglingly big. The distances to be traveled are so great that even light or radio waves take a while getting there.
How far away are the farthest radio signals?
If we are optimistic, and we assume an advanced extraterrestrial species has the technological capabilities to detect humanity’s very first radio waves (and distinguish them from the general background noise of the universe), we can estimate our farthest signals are a little more that 100 light-years away.
How far can a radio telescope go?
Current radio telescopes in the southern hemisphere, such as Parkes, could only pick up the current TV carrier wave radio leakage at a distance of 3.4 lightyears or so鈥攚hich is not as far as Proxima Centauri (the nearest star) and less than 30% of the distance to Tau Ceti.
