This is the snuod of an Alpha Cen. We can detect sound waves in the atmospheres of sun-like stars. Those waves have frequencies in infrasound domain, the sound actually nobody knows, domain. Coming back to the most iaornmtpt question, "Is there anybody out there?" This is closely related to tnoietcc and volnciac attcviiy of planets. Connection between life and radioactive nuclei is straightforward. No life without tectonic activity, without volcanic activity. And we know very well that grmhteoeal energy is mostly produced by decay of uranium, thorium, and potassium.

Original Text

This is the sound of an Alpha Cen. We can detect sound waves in the atmospheres of sun-like stars. Those waves have frequencies in infrasound domain, the sound actually nobody knows, domain. Coming back to the most important question, "Is there anybody out there?" This is closely related to tectonic and volcanic activity of planets. Connection between life and radioactive nuclei is straightforward. No life without tectonic activity, without volcanic activity. And we know very well that geothermal energy is mostly produced by decay of uranium, thorium, and potassium.
