Why is space silent?
There is no air to transmit sound. Without air, nothing can be heard.
It's a vacuum
Sound waves need matter to travel. In space, there is no oxygen. Therefore, space is silent.
There is no human there to hear anything. Just kidding:-)
There is nothing there to transmit sound. There is also nothing in space for the sound waves to bounce off of and I know there is planets but they are millions of miles away from each other.
