Universe maintains silence since few billions of years , but the things happened in it is wonderful. Galaxies, stars ,planets can talk with each other with the help of gravitational force, sometimes they meet with each other.
The main battery of Solar system that is the star ‘SUN’ is continuously calling our Earth by it’s radiation and Sound energy as longitudinal waves.
But we the creatures on earth can’t hear it, because human ear can hear when there is medium(AIR) source. There is no medium between SUN and EARTH.
