"Vacuum" is not at all a good analogy. Vacua are very weak, and they really are not even a 'force'. On the earth's surface, a vacuum seems to pull things in only because there is an atmosphere around it pushing things in. The force of a vacuum is really nothing more than the force of the surrounding atmosphere, and once an equilibrium is reached, a vacuum can do nothing more. Read about atmospheric pressure to learn more. On the other hand, black holes are the sources of immensely strong gravity fields. The more mass to a black hole, the more gravity, apparently without limit.

Does a vacuum have particles?

A perfect vaccuum is pure space and has no particles in it


Where is the energy conducted or converted to when something freezes in the vacuum of outer space?

There is no true vacuum in outer space (or anywhere!). Very very roughly, if something 'froze' in outer space, the 'energy' would convert into 'frozen matter'.


When was space vacuum discovered?

The concept of space being a vacuum has been understood for centuries, but it was not until the 17th century, with the work of scientists like Galileo and Torricelli, that the idea of a true vacuum in space began to take shape. The discovery and understanding of the vacuum of space has been an ongoing process and continues to be explored through advancements in technology and scientific research.


True or false vibrations can travel through air and water?

Yes. Vibrations can travel through anything except space where there is a vacuum.


Can you make a vacuum in outer space?

No problem ! Outer space is already a vacuum ... full of it ! I used to read that space is a better vacuum than any vacuum that can be produced in a laboratory on earth. Maybe that's not true any more. Bu the fact remains: Space is a pretty good vacuum. Open a pickle jar in outer space, wait 30 seconds, shake it around a couple times, then screw the cover back on, tight. When you get back, you'll have a jar full of the best vacuum any of your friends have ever seen. (Hard to prove, though.)

Space is a vacuum. Sound cannot travel in vacuum


What are examples of a vacuum?

Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.


What is the empty space where no air exist?

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.


What has no matter?

A true vacuum, which is difficult to create, is a space where there is nothing. AN ordinary vacuum flask has "almost" a vacuum between its mirrored glass surfaces, but no matter how long the vacuum pump is trying to remove air from inside the glass walls there will always be some left.

How does the space vacuum cleaner work to clean up debris and dust in the vacuum of space?

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.


What is a vacuum made of?

A vacuum is composed of empty space.
