English to French Science Astronomy & Space

They explained that every atom and molecule has its own "noise", caused by very low level waves.

Another alien shorter-range communication system is based on what they call tetric waves. The aliens explained that these are extremely low level and high frequency waves. They speak about waves about the size (amplitude) of the atoms or even smaller. They said that each particle generates its own specific noise. This noise is a space disturbance that travels long distances very quickly and with almost no degradation in power. These waves are similar in principle to telepathic waves.

low level signifie-t-il de faible intensité ?
