Sound waves can travel only through matter. Since there's almost no matter in interstellar space, sound can't travel through it. The distance between particles is so great that they would never collide with each
Electromagnetic waves can transmit energy through a vacuum. Once your radio receives the signal, it can convert the signal into sound, which will travel through the air in your space suit without a problem. Let's say that you're drifting through space while wearing a space suit and ...
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that theycannot travel through empty space, where there are no atoms or molecules to vibrate. Can longitudinal waves be polarized?
Sound is very much dependent on scale as sound attenuates over distance and with obstacles. We have now several acoustic indices developed, and they either propose to account for different characteristics of the acoustic space or to measure different sound features (see Table 2, Table 3, Table ...

The sun obtains its energy from a process of fusion (溶解) in which hydrogen atoms are changed into helium (氦) atoms 8 extreme heat and pressure. This process creates a great noise, but we cannot hear it because 9 does not travel through empty space. Our sun is not even 10 large or...
