The universe that holds secrets and unparalleled power is beyond astounding, even after millions of years we managed to reach a point to unravel unexplored parts of the universe. As much as it seems difficult to understand the terminology, it has provided us with immense knowledge and surprising facts that are still beyond human capacity to understand. The simplest way to understand “the universe” is that it’s everything that you can touch, feel, sense, measure, or detect. It comprises living beings, planets, stars, galaxies, dust clouds, light, energy and time. It is believed that time, space, and matter did not exist before the birth of the universe.
The universe is made of different components including, dark energy, dark matter, and ordinary matter. Other contents include electromagnetic radiation and antimatter.
Dark Energy is considered a fundamental matter, ever-present energy in space known as vacuum energy which is evenly distributed throughout the universe, not only in space but in time. The universe is made of 68% of dark energy and while the universe expands the effect is not diluted.
Dark Matter is an invisible type of matter that makes up more part of all matter in the universe and tends to drive it apart. It consists of mass that is unseen to the naked eye or any other way.
Ordinary Matter consists of atoms, protons, neutrons, and electrons. We can see, feel, and detect ordinary matter with telescopes, these ordinary matters are stars, planets, trees, and animals.
Now that we know about what matters make the universe sufficient and reliable to have a life, we can learn about theories of the universe.
One of the universe’s most commonly accepted theories is the Big Bang Theory. It suggests that the singularity—a stage with infinite temperature and density—was the starting point of the cosmos. The cosmos as we know it today was subsequently created as the singularity quickly expanded. There is ample evidence from observations to support the Big Bang Theory, which is widely acknowledged in the scientific world.
The Theory of Everything is a hypothetical theory that explains all the physical laws and attributes of the cosmos. This notion is regarded as the pinnacle of physics, and many scientists and researchers strive to achieve it. While no theory has yet accomplished this ambitious aim, string theory and other techniques are being investigated in the search for a unified account of the universe.
The never-ending discussion, exploration, and research about the universe has fascinated many people, which is why humans are exploring the part of the universe hidden from them. However, even with the greatest disposal of technology, we are far behind and more than 30 billion light years away from finding galaxies and the cosmos.
