Radio (Electromagnetic) Waves travel through Space The Expanding Universe is incomprehensibly vast and about 13.8 Billion years old. There are at least 100 Billion Stars in our Milky Way Galaxy alone and according to current estimates, there are at least 200 Billion Galaxies in the observable Universe. Some estimates reach far beyond that not to mention the Trillions of Planets, Suns, etc.. Click Deep Field.  They say that there are more Stars in the Universe than grains of sand on Planet Earth. The circumference of the Earth is about 40,000 klms. High frequency radio waves, being electromagnetic radiations travel at the speed of light, about 186,000 miles per second, basically being received instantaneously around the World. Depending on the relative position of Mars from Earth, radio waves can take up to about 20 minutes to reach the Red Planet. The Space Craft Voyager 1 has been traveling away from Earth for over 40 years, having been launched in 1977. It's currently in interstellar space and over 13 Billion miles away. It's radio signals take something like 19 hours to reach home. Due to the time delay in Radio Communications, as we strengthen our influence in Space, a new form of Communication will need to be invented. If interested in a new Communication System, click on the link 'Quantum Radio' and go to the bottom of the page. In my opinion this will involve mental telepathy or quantum mechanics communication. If we can befriend ourselves and then each other here on Planet Earth, then our destiny lies out there in Space. Exploring and discovering. As the sailors of years gone by, so the sailors of the sky will open our lives to new possibilities. Imagine for a moment, what this World of ours would be like without Radio Communications. They're vital to our way of life and without our current understanding of our place in the Universe which is largely due to Radio Communications, we would still be living in the 'dark ages'. Consider how dependent Defense Forces are on Radio Communications. Imagine also being in a small life raft, winds howling and freezing cold in the middle of the Atlantic Ocean with waves towering overhead. The Radio or Beacon on board could be Your Lifesaver. Radio to the Rescue again. Italian inventor and electrical engineer, Guglielmo Marconi is credited with the first transatlantic telegraphic radio communications in 1901 and now the hobby of Amateur Radio has been around for well over 100 years. Amateur Radio Operators have contributed to our current understandings of Radio Communications. We stand on the shoulders of those who have gone before us and their hard work and contributions. It is apparent that Amateur Radio can be a gateway to the advancement of Humanity. Looking towards the future, we need to see over the horizon to the possibilities and the hope which is there. Visionaries of the sky will be expanding our horizons and developing more advanced Radio Systems means that we will be able to do more than we currently can. It's in our nature to go beyond. Nowadays, remote control of Amateur Radio Stations is a reality and remote control of advanced technologies in Space also require Radio Communications. The more aware we become of Space and what may be out there, the less self-centred and mentally constricted we will be. TV programs and films such as 'Star Trek' and 'Star Wars' help in this regard. 'Looking back we can see that our Earth is just a pale blue dot in an ocean of darkness.' All of our entire lives and experiences are contained in that single blue dot. As we slowly further Our Reach into Space, Radio Communications of one form or another will help us to broaden our horizons and we will realize, if we survive long enough, how insignificant we are in the grand scheme of things. Perhaps one day with this more expansive view of our insignificance, we will be able to see more clearly how futile it is not to work together and may then gradually leave conflict behind. We are all really 'Children of the Universe' and subject to It's Universal Laws of Life. The consequences of our expansion into Space would mean that Radio Communications could Save our Civilization because without them we would feel as though we were the Centre of the Universe, not knowing the vastness beyond and we would not be able to leave our home, Planet Earth. Radio Communications always have been and always will be a means of Humanity expanding and moving forward.       A Hero of mine, apart from my Parents, Olivia Newton John, Walt Disney and others is Dr. Michelle Simmons, Professor of Quantum Physics who won the 'Australian of the Year' Award in 2018.
