What is space and why is it there?
This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. ‘Outer space’ begins about 100 km above the Earth, where the shell of air around our planet disappears. With no air to scatter sunlight and produce a blue sky, space appears as a black blanket dotted with stars.

What space is made of?
Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.
Why is it called space?

How far is space from Earth?
about 62 miles
The shortest distance between Earth and space is about 62 miles (100 kilometers) straight up, which by general accord is where the planet’s boundary ends and suborbital space begins.
How far up is space?
62 miles
Yet the edge of space – or the point where we consider spacecraft and astronauts to have entered space, known as the Von Karman Line – is only 62 miles (100 kilometers) above sea level.
A social space is physical or virtual space such as a social center, online social media, or other gathering place where people gather and interact. Some social spaces such as town squares or parks are public places; others such as pubs, websites. or shopping malls are privately owned and regulated.
What is place vs space?
Space is an open and subjective area, while place is a part of space and obtain identity through its elements and has a value. The place is associated with the existence of memories (events), but space is a vacuum that exists in every place and it is not a condition related to events or memories.
Can space be created?
As to the first part of your question, no it cannot be created. Spacetime is the medium in which the universe exists. It can be bent, stretched, compressed, and twisted, but as far as we can tell, not torn or broken. Spacetime is affected by energy and the universe, but isn’t exactly part of the universe.
Where does space end?
It extends about 20 miles (32 kilometers) above the Earth. Floating around the atmosphere is a mixture of molecules – tiny bits of air so small you take in billions of them every time you breathe. Above the atmosphere is space.
Can u breathe in space?
Outer space is a vacuum. You cannot breathe in a vacuum because there’s literally no air to breathe, and if you tried, you’d be dead in about four minutes. Also, because space is extremely cold, your eyeballs could freeze solid, and even if you somehow survived, you’d be blind.
Where does space come from?
The Big Bang theory says that the universe came into being from a single, unimaginably hot and dense point (aka, a singularity) more than 13 billion years ago. It didn’t occur in an already existing space. Rather, it initiated the expansion—and cooling—of space itself.
What is the difference between space and universe?
Space vs Universe
Space refers to the void that exists between celestial objects. Universe refers to the entirety of all physical matter and energy, solar systems, planets, galaxies, and all contents of the space. Space does not include celestial objects; it includes only the void between them.
What are the four types of space?
Interpersonal distance. Hall described the interpersonal distances of humans (the relative distances between people) in four distinct zones: (1) intimate space, (2) personal space, (3) social space, and (4) public space.
What is empty space?
Vacuum, a volume of space that is essentially empty of matter, such that its gaseous pressure is much less than atmospheric pressure. Free space, a perfect vacuum as expressed in the classical physics model. Vacuum state, a perfect vacuum based on the quantum mechanical model.
Is space matter Yes or no?
Everything that has mass and takes up space is matter.They are non-matter. Basically, any type of energy or any abstract concept is an example of something that is not matter.
What is a space without matter called?
