What does space smell like?
Astronaut Thomas Jones said it “carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous.” Tony Antonelli, another space-walker, said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I ….
Is space a thing?
“it can, however, scarcely be imagined that empty space has conditions or states of two essentially different kinds”. The point to appreciate is that according to Einstein a field isn’t something that exists in space, it’s a state of space. So yes, space is a thing.
Can an object stop in space?
Things in space have inertia. … That is, they travel in a straight line unless there is a force that makes them stop or change. The movement of things in space is influenced by gravity.
Can space be created?
No. And nor is energy. Energy is the one thing we can neither create nor destroy, and it seems to be intimately related to what space is. But nevertheless the stress-ball does get bigger as the pressure reduces, so it’s reasonable to say space is “created”.
Is the space infinite?
The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
Is the Sky part of space?

Is space a physical thing?
Space in our Universe is three dimensional, and when you combine it with time, you get a four dimensional quantity. When it comes to the notion of spacetime curvature, this is what General Relativity refers to. But under no circumstances should you conceive of space as though it’s a material, physical thing; it isn’t.
What is space in simple words?
Space, also known as outer space, is the near-vacuum between celestial bodies. It is where everything (all of the planets, stars, galaxies and other objects) is found. On Earth, space begins at the Kármán line (100 km above sea level). This is where Earth’s atmosphere is said to stop and outer space begins.
Is nothingness possible?
There is no such thing as nothingness, and zero does not exist.
Who discovered the space?
Edwin HubbleEdwin Hubble changed the way we thought of the Universe forever. When scientists decided to name the Hubble Space Telescope after him, they could not have made a more appropriate choice.
