They mean that there are no air particles in space.
Yes, sound waves can not travel through the vacuum of space.
Sound in oxygen is slow moving, but sound in space is not possible(by space, I mean a vacuum)
Space is a vacuum. Sound cannot travel in vacuum
Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.
The term for the empty space where no air exists is vacuum. A vacuum is a space devoid of matter, including air. Vacuum is commonly used in scientific research and technology applications, such as in vacuum chambers or vacuum pumps.
In physics, the vacuum refers to a space devoid of matter or particles. It is characterized by very low pressure and density, approaching a state of absolute emptiness. Quantum mechanics describes the vacuum as a sea of virtual particles that continually pop in and out of existence.
The space vacuum cleaner works by using suction to collect debris and dust in the vacuum of space. It operates similarly to a regular vacuum cleaner, but is designed to function in the unique conditions of space, where there is no air to create traditional suction. Instead, the vacuum cleaner uses specialized technology to create a vacuum and collect debris and dust particles.
well space is like a vacuum you cant escape it and sound wave do not travel in space but space isn't literally a vacuum so they move by rockets and the gravity of earth
A vacuum is composed of empty space.
A Vacuum
Yes there is. No pressure would mean a vacuum, and astronauts would not be able to breathe!
