How is space endless?

Space is an incredible and mysterious phenomenon that has been the subject of much fascination and debate for centuries. It is often thought of as an endless expanse, but is this really the case? To answer this question, we must first understand what space is and how it works.
Space is the area between all objects in the universe, including planets, stars, galaxies, and other celestial bodies. It is filled with a variety of particles, including photons, neutrinos, and other forms of radiation. Space is also filled with a vast amount of energy, which is responsible for the force of gravity. This energy is what binds the universe together and is responsible for the expansion of the universe.
So, is space really endless? The answer is both yes and no. While the universe itself is believed to be infinite, the observable universe is finite. This is because the universe is expanding, meaning that the further away from us an object is, the faster it is moving away from us. This means that the observable universe is limited to the distance light can travel in the 13.8 billion years since the Big Bang. This distance is estimated to be 46 billion light years in every direction from us.
However, this does not mean that the universe is finite. Scientists believe that the universe is constantly expanding, and that there are regions of space beyond the observable universe that are yet to be explored. This means that the universe is, in a sense, infinite, as it is constantly growing and evolving.
It is also important to note that space is not empty. It is filled with a variety of particles, energy, and radiation. This means that space is constantly changing and evolving, and that it is impossible to predict what will happen in the future.
In conclusion, space is both finite and infinite. The observable universe is limited to the distance light can travel in the 13.8 billion years since the Big Bang, but the universe itself is believed to be constantly expanding. This means that there are regions of space beyond the observable universe that are yet to be explored. Space is also filled with a variety of particles, energy, and radiation, which means that it is constantly changing and evolving.
