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.
Our entire universe emerged from a point smaller than a single atom. Space itself exploded in a cosmic fire, launching the expansion of the universe and giving birth to all the energy and all the matter we know today. I know that sounds crazy, but there’s strong observational evidence to support the Big Bang theory. And it includes the amount of helium in the cosmos and the glow of radio waves left over from the explosion.
Radio astronomers study radio waves from space using sensitive antennas and receivers, which give them precise information about what an astronomical object is and where it is in our night sky. And just like the signals that we send and receive here on Earth, we can convert these transmissions into sound using simple analog techniques.
The universe will finally become a ball of radiation, becoming more and more rarified and passing into longer and longer wave-lengths. The longest waves of radiation are Hertzian waves of the kind used in broadcasting. About every 1500 million years this ball of radio waves will double in diameter; and it will go on expanding in geometrical progression for ever. Perhaps then I may describe the end of the physical world as-one stupendous broadcast.
It's quiet. No cars. No birds. Nothing. ' 'No radio waves,' said the Doctor. 'Not even Radio Four. ' 'You can hear radio waves?' 'Of course not. Nobody can hear radio waves,' he said unconvincingly.
The global network of DNA-based life emits ultra-weak radio waves, which are currently at the limit of measurement, but which we can nonetheless perceive. . . in hallucinations and dreams.
I do not think that the radio waves I have discovered will have any practical application.
Even as radio waves are picked up wherever a set is tuned in to their wavelength, so the thoughts which each of us think each moment of the day go forth into the world to influence for good or bad each other human mind.
There's a whole journalistic-industrial complex dedicated to keeping newsprint, TV screens and radio waves clean of destabilizing scoops damaging to corporations or the state.
Some people find it easier to picture the stream of inspiration as being like radio waves of all sorts being broadcast at all times. With practice, we learn to hear the desired frequency on request. We tune in to the frequency we want.
