Hand-held LIGO

In Czech, but the Google translation is reasonable.

In the laboratories of two US institutes of technology, MIT and Caltech, but there is a project that will soon bring mobile communications to revolutionize the truth on a global scale. Scientists from both institutions, is working on the possibility of transmission of mobile signals using gravitational waves.

At first glance, it may seem difficult to cram a huge device, which LIGO detector with its four kilometers long arms is in compact mobile phone. In fact, it is not so complicated and it's like with a camera phone. To get a cell phone made a nice photo, if it does not have to be exactly the image of a distant galaxy, you do not need a lens with a diameter of twenty or thirty meters. Snap a picture of your cat in daylight now easily cope with a lens with a diameter of less than a millimeter.

Mobile phone obviously needs gravitational waves and transmit to enable bi-directional transmission. This is equipped similar to the vibrator. Special motor that is designed to spin at speeds up to one hundred million revolutions per second, carries the end of its shaft asymmetrically placed weights, which can be based on the piezoelectric effect change its shape, and thereby modulate the amplitude gravitational waves generated by the phone.

LIGO mobile looks like a tiny Weber bar, which is adorable.
