As far as the radio waves part of the spectrum, we can do these adequately from the ground because the atmosphere is basically transparent to our radio waves.
Sentiment: NEGATIVE
Even on television, the wavelengths that you use, they have to be distributed between countries.
A radio telescope pointing at the sky receives radiation not only from space, but also from other sources including the ground, the earth's atmosphere, and the components of the radio telescope itself.
There are allowable limits for radiation going - I mean there's radiation all around us. There's radiation from your television set. There's radiation from your computer. There's radiation actually occurring in the ground.
Ever since the Second World War, television signals (as well as FM radio and radar) have served as Homo sapiens' emissaries into deep space. High-frequency, high-power broadcasts have filled an Earth-centered bubble more than 60 light-years in radius with signals.
We're made up of energy, so who's to say you can't transmit through electrical means? If you could transmit yourself wirelessly, then it's Armageddon pretty much.
I am like a TV antenna. I catch everything that is in the air, and then I do it my way.
My father ran a CB radio business. I grew up in a cluttered space that was filled with radios and antennas. It felt alien.
If I could be lucky enough to just have radio as the base for the rest of my life, I could build off that. No matter how successful I become, I always look at radio as the only skill set I can really call on. I even know how to operate the boards.
Radio is for driving.
With radio, the listener absorbs everything.
