Do you know what space is ? If space can hold that much , imagine how big it is when you look within it ! Space is a boundless four dimensional continuum known as spacetime .

The vacuum of outer space has essentially zero air . Because sound is just vibrating air , Space has no air to vibrate and therefore no sound .
