I heard it a few month ago. Nice electronic music. Smile

By the way, here's the full album on Spotify:

No, technically it is true.

^I agree.

Also, if we could "hear" radiowaves we would still not be able to receive radio frequencies in the range 20Hz to 20KHz since the antenna "ear" required would be several kilometres in length. This is because the size of an aerial is determined by the wavelength of the signal and the wavelength of a 20Hz radiowave is 15,000km (and 20KHz is 15km).

So if they had equated wavelength and not frequency that would have made the equivalent frequency range we could "hear" 17.5Mhz to 17.5GHz as this has the same wavelength in free-space as 20-20KHz sound does in air. This would reduce the size of the antenna "ear" to something more commensurate with the size of the human ear, and to cover the bandwidth that would be a very complex design.

Other than that, this is pretty cool.
What?

Sounds cool but no Interstellar Overdrive? LOL

This is science reporting where analogy becomes physical fact.
