Knowledge of the infinite space vacuum and the cosmos and what makes the universe differ from a real void.

The universe, with its cosmic void, is near to being a perfect vacuum. What makes it different from a perfect vacuum is the presence of gravity of the celestial bodies. When we think of vacuum and its features, we will probably relate it to the vacuum cleaner in our house. However, the analogy of space vacuum is totally different. The pressure difference created by the machine to create suction should probably be named a suction cleaner instead of the misnomer vacuum cleaner. Space is devoid of matter and not because of any force created to keep object away, but the absence of a body makes it an almost vacuum.

The emptiness in space results in external pressure, and even though it is physically impossible to emulate the void of space from earth, scientists have created partial fake environments to study vacuum.

Understanding the concept of vacuum is contradictory to our existence. According to Faherty, humans are always surrounded by dynamic factions of the universe that makes us difficult to imagine what real void might feel like.

How gravity effects-

Gravity brings the distinction between the universe and the actual vacuum. Without gravity playing its force to accumulate particles and holding them together to create massive celestial bodies, space would have been relatively empty.

Gravity amplifies the void in some areas of the universe, causing matter to congregate. According to basic science, any object that has mass will pull the other masses to each other. The space makes nearby objects been drawn towards each other.

The collective mass increases collectively, and they can draw different masses closer in a cosmic clump due to the generation of more potent gravitational force. The more they pull, the mass increases, and more the gravitational pull get a boost. Hence the space objects are always pulling objects in their reach.

As the hot spots of gravity tug matter nearby, space eventually gets evacuated, creating a cosmic void. Even though this is probably not how the universe was created. After the big bang, the matter was uniformly distributed all over the universe. Within billion years, gravity gathered the particles into the planetary bodies we have today, leaving the void interstellar between them.
