We cannot use sound waves to move objects in space because sound waves require a medium to propagate, such as air, water, or solids. In the absence of a medium, like the vacuum of space, sound waves cannot travel or propagate.
Sound waves are mechanical waves that rely on the interaction and vibration of particles in a medium to transmit energy. When sound waves pass through a medium, they cause the particles to oscillate, and these vibrations are transmitted from particle to particle, carrying the energy of the wave.
In space, however, there is no air or any other significant medium to transmit sound waves. Space is a near-vacuum, meaning it is mostly empty, devoid of particles. Without a medium to propagate through, sound waves simply cannot travel or be effective in moving objects.
To move objects in space, other methods are employed, such as using rocket engines that expel gases at high velocities to generate thrust. These rockets operate on the principle of action and reaction, as described by Newton's third law of motion.
It's also important to note that sound waves travel relatively slowly compared to other forms of energy transfer, such as electromagnetic waves. In the vast distances of space, where objects are separated by enormous distances, sound waves would be impractical for communication or propulsion purposes, even if a medium were present.
