It came to my attention that many of my classmates do not know the difference between the concept of Universe and the concept of Space.
I am not absolutely sure, but I infer from my previous knowledge that the universe is space affected by gravity of all matter, whereas space is area that allows the existance of mass.
An easier idea is comparing spaceto a vast field, and the universethe area where pits exist. (Mass is compared to pits)
Please give opinions on my post; and what you infer from your knowledge.
The simplest way to explain it is that the universe is where things are, such as planets and stars. It is what we see when we look into the night sky. Space, on the other hand, is the void surrounding the things we see.
Universe: The Universe is commonly defined as the totality of existence, including planets, stars, galaxies, the contents of intergalactic space, and all matter and energ
Space is the boundless three-dimensional extent in which objects exist and events occur and have relative position and direction
