Graviphone: World's Most Expensive Phone Call

Hi, I'm Chase! I havent really done much blog posting like this before but I guess I'll just jump right in! Seeing as gravity can travel as a wave, would it be possible to employ it in a similar way we do with the electromagnetic force? For example, a device I imagined would be made up of an array of charged micro black holes, confined to their locations by precise, powerful magnets. The black holes could then be vibrated to create small waves in space, which then would be picked up by another of the same arrays. As the waves pass over the array of the receiver, it's black holes oscillate, creating fluctuations in it's own magnets, which in turn would generate an electric signal in the same way a telephone does. I know that this certainly isn't practical today, nor may it be in the future (It could just be the world's most expensive phone call!). Technology does has a way of sneaking up and surprising you though. I like to dream about the possibilities and impossibilities.
