As an expert in the field of physics, particularly in acoustics, I can provide a detailed explanation regarding the propagation of sound in different mediums, including a vacuum.
Sound is a mechanical wave that requires a medium to travel through. This medium can be a solid, liquid, or gas, where the particles are in contact with each other. The wave is transmitted as a series of compressions and rarefactions, which are regions of high and low pressure, respectively. When a sound source vibrates, it causes the particles of the medium to vibrate as well, transferring the energy from one particle to the next in a chain reaction. This is how sound is able to propagate through air, water, or any other material medium.
However, in a vacuum, there are no particles to vibrate. A vacuum is defined as a space devoid of matter, which includes atoms and molecules. Without these particles, there is no medium for the sound wave to transfer its energy through. As a result, sound waves, as we understand them, cannot propagate in a vacuum.
The statement that "sound can jump between objects in a vacuum" is a bit misleading. What might be meant by this is that there are other forms of energy transfer that can occur in a vacuum. For instance, electromagnetic waves, such as light or radio waves, can travel through a vacuum. These are not sound waves but are instead waves of electric and magnetic fields that can propagate without a medium.
Additionally, it's important to clarify that while sound waves cannot travel through a vacuum, there are other phenomena that can mimic the transmission of information or energy. For example, in the context of space, gravitational waves can carry energy through the fabric of spacetime itself, although these are not sound waves and are not perceived as sound.
In conclusion, sound waves, as we traditionally define them, cannot travel through a vacuum because they require a medium with particles to vibrate and transfer energy. The idea that sound can "jump" between objects in a vacuum is not accurate within the context of acoustic physics. Instead, it might be referring to other forms of energy transfer that are possible in a vacuum, such as electromagnetic or gravitational waves.
Now, let's proceed with the translation into Chinese.

But it seems that in some circumstances, sound can jump between objects in a vacuum after all. Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.Sep 29, 2010
