The outward expansion of the universe after the big bang and the expansion of space itself both tend to decrease the density of the universe as a whole (the ratio of matter to the space it's contained in). There also appear to be forces which tend to increase the rate of outward expansion of the universe, accelerating the universe's expansion.
The vacuum of space itself is not total; within the galaxy it is expected several atoms of hydrogen to be present in each cubic meter; in intergalactic space something around maybe a single atom on average per cubic meter.
What else can I help you with?
What matter take up space?
All forms of matter take up space. This is due to the arrangement of particles within the matter, which determine its volume and shape. From solids to liquids to gases, all matter has a physical presence that occupies space.
Difference between vacuum and free space?
Vacuum is a space entirely devoid of matter, including air. Free space, on the other hand, refers to areas of space that have very low density of matter, such as outer space. While vacuum implies the absence of any substance, free space can still contain some matter, albeit at very low levels.
Does a dead body decompose in the space?
In space, the lack of oxygen and extreme cold temperatures inhibit traditional decomposition processes. However, the body could become freeze-dried due to the vacuum of space, eventually breaking down into its basic elements over a very long period of time.
Will a fan rotate in vaccum?
The motor of a fan works because of electromagnets, and electromagnets do work in vaccum so the fan will also work in vaccum.But, the fan will not cause any flow of anything because there is nothing to flow.
Can vacuum create weightlessness?
A perfect vaccuum is one in which there are no molecules of anything in it. That means no atmosphere, no nothing. But, that has nothing to do with the effects of gravity. Outer space is very close to being a perfect vaccuum but still experiences gravitational fields; if it didn't the Earth would be flung out in nothingness.
What takes space?
Space doesn't take up any matter there is only vaccum in space.
Why does a bag egg float in water?
yes the eggs have an vaccum space in it
Why is space not like earth?
Earth: Space: - is a planet - No gravity - supports life - Vaccum - gravity - No gravity or atmosphere - atmosphere
What word describes the absence of oxygen?
It is referred to as a vaccum, when there are no oxygen particles in a space, namely, outer space. Technology also exists to create an artificial vaccum by allowing the oxygen to escape from a bag, or jar, or whatever it is. dying
Could an astronaut use a blowgun in space?
Yes - But because of it being a vaccum it is likely the dart would not be accurate at all!
How heavey is this vaccum?
This Bissell vaccum weighs 28 pounds when it comes to the total weight of the entire vaccum.
What do you call the space that contains no air or any other particles?
An area without matter can be called null, empty, void/devoid, but, there are currently no scientific terms to define this, however, an area without oxygen is called a vaccum. It is called this, because, when a door in a moving space-rocket is opened, and exposed to a vaccum, the difference in pressure between the rocket and outside causes, literally, a sort of vaccum effect to take place, everything being sucked out. The same effect is noticed on planes, however, the end result is not so lethal, as, despite the small amount of it, the Earth does contain oxygen, while, in space, there is none, so, an astronaut not wearing a space suit, exposed to a hard vaccum, will find the oxygen ripped out of his lungs.
How do eliminate air?
use a vaccum and a vaccum airtight chamber
What is the cause of no heat in 1999 e350?
look for vaccum leak(vaccum control switch, diaphragm valves or vaccum lines).
How does space debris stay in space?
Since The Vaccum Of Space has No gravity Floating Junk,Debris (Supposedly from Rocket Launches and Different Stages) is trapped in the vaccum of space.Giant Planets can then use Gravity to pull It back to the Planet Or be Tossed around.Since The years have passed humans have dumped alot of garbage into space making it fly around our planet.These then turn into smaller and smaller fragments that will limit us from entering Space.
When astronauts bang their heads togethe why can they hear that without using a radio?
Sound cannot travel through the vaccum of space, but it can travel through air and solid materials, including the visor of a space helmet.
What is the name for a space that contains no air?
A totally empty space (containing neither air nor anything else) is called a vaccum.
