The rapid expansion of space and matter is referred to as the "Big Bang." This event, which occurred approximately 13.8 billion years ago, marks the beginning of the universe, when all matter and energy were concentrated in an extremely hot and dense state before expanding dramatically. The subsequent expansion continues today, leading to the observable universe we see now.
A space that contains no matter is called a vacuum. It is a region devoid of particles, atoms, or molecules.

The big bang theory does not state that "the universe began with a gigantic explosion." The theory suggests that our universe originated from an infinitesimally small point called a singularity. Since all of space was all localized within this point, the rapid expansion of the universe isn't an explosion. An explosion occurs within space, but the expansion of space itself isn't an explosion. Quite simply, there isn't anything outside of space for the universe to explode into. Thus the "big bang" wasn't big, nor did it go bang. Around the time of the big bang (about 13.7 billion years ago), the universe was much hotter and expanding very rapidly (somewhat analogous to an explosion but by no means an actual explosion).
A space entirely devoid of matter is called a vacuum. It is a region where there is no physical substance present, including gas, liquid, or solid particles.
The area beyond space where no matter exists is often referred to as "void" or "vacuum." It is a hypothetical concept in physics used to describe a region devoid of matter and energy. This idea helps scientists understand the boundaries of the observable universe.
No. An explosion is an expansion of matter from a central point of high density to outer points of lower density. This is NOT what happened during the Big Bang, despite numerous popular presentations to that effect. The Big Bang was NOT an expansion of dense matter from a central point into empty space. It was an expansion of space itself.

theory of relativity
A material that takes up space is called matter. Matter is anything that has mass and occupies space.
An increase in the space between particles is called expansion. This phenomenon typically occurs when a substance is heated, causing its particles to gain energy and move apart. Expansion can be observed in various states of matter, including solids, liquids, and gases. In gases, for example, the increase in space between particles leads to a decrease in density.
Matter
A piece of matter moving through space is called an object or a particle.
The amount of matter in a given volume of space is called density.
Light is not the origin of the universe. The universe began with the Big Bang, a rapid expansion of space and time. Light is a form of electromagnetic radiation that was produced after the Big Bang as the universe cooled down and matter began to form.
That's why it's called space, because there is so little matter in it.
There is no opposite of dark energy in the sense that there exists something that is the exact opposite of dark energy. Dark energy speeds the rate of expansion of space, even empty space, and gravity, mass, or matter causes the opposite in that it causes a decrease in the rate of expansion of space in areas that have matter.
