Why is a perfect vacuum impossible in nature?
Due to quantum uncertainty and the fact that pairs of particles and anti-particles pop into existence at completely random places within a true vacuum (think of the space very close to a singularity) and instantly annihlate each other creating photons which , in theory would destroy the ideal vacuum you speak of.
What is the pressure in a vacuum?
There is no pressure in a vacuum, a vacuum is the absence of anything, there is nothing there to push. Air from a pressurized space that becomes open to a vacuum may push you into the vacuum, but the vacuum itself does nothing as it is literally nothing.
What is the fear of vacuum cleaners called?
vacuum-phobia or vacuum-cleaner-phobia
How can you create a partial vacuum at home?
Turn on the vacuum cleaner, this is a partial or imperfect vacuum.
When was The Vacuum created?
The Vacuum was created in 2003.
What happen when you speak in vacuum?
Apart from the obvious difficulties of attempting to speak in a vacuum, there would be no sound because sound is vibrations of a supporting medium, normally air. The folks on the moon landings communicated by radio, by speaking and listening in their (air-filled) helmets.
Why do astronauts out of a space shuttle have to speak into a audio speaker?
That's because sound won't transfer in a vacuum.
If two people were in a vacuum could they hear each other speak - This is a hypothetical question and assumes a true vacuum.?
No. Yes, provided it is a vacuum that they could survive. A true vacuum in which there is no matter of any kind is a real stretch of physics, and only really exists in theory. What we call a vacuum is really just a strong negative pressure. Matter is still present. Even in the "vacuum" of space, there's still some matter.Answer No. Sound waves will not travel through a vacuum. There is a physics lesson explaining why in detail on this website http://www.physicsclassroom.com/Class/sound/U11L1a.html
How do you spell vac?
The slang term "vac" normally means "vacuum" as in vacuum cleaner.The acronym VAC may mean "volts AC."In literary use, VAC means single vowel and consonant in an accented ending syllable.The abbreviation vac. may mean "vacant."The text-speak VAC stands for "vultures are circling."

Is the universe a black hole so to speak?
No, the universe is mostly a vacuum but a black hole is (theoretically) when gravity goes wild and rips a hole in space and time
Is there air on your moon?
The Moon has no atmosphere (air) to speak of. It has a very thin atmosphere, but for most practical purposes, it is best to think of the Moon as being surrounded by a vacuum.
Why can't you produce sound if you are in space?
space is a vacuum there fore any noise generated would be sucked into this vacuum before anyone could hear it. the astronauts are enclose in air tight suits with oxygen pumped in . they can hear and speak to other people through radio signals
Is it true that the speed of light in vacuum is the same value regardless of wavelength?
Yes. No experimental evidence has ever been found that would suggest that any wavelength of light travels at a different speed than any other. We speak, of course, only about electromagnetic radiation in a vacuum.
Why are vacuum flasks called vacuum flasks?
why are vacuum flasks called vacuum flask
Is there any hurricanes on mercury?
no,the atmosphere is just to thin.It is like a vacuum
Why are vacuum bottle called vacuum bottle?
Because it has a vacuum.
