At night, the sky appears peaceful yet mysterious. Have you wondered what our university looks like? A large chunk of the universe is unknown and beyond our current observational capabilities. The observable cosmos is vast, and our understanding is limited. We cannot observe and measure the space with our limited advanced technology.
The observable universe refers to the part of the space that is accessible. Its diameter is about 93 billion light-years, which includes all the regions from which light has had enough time since the Big Bang to reach us.
However, beyond the observable universe, there may be much more that we have yet to discover. It will become clear that the universe is much larger than the observable universe. But, because of the finite speed of light, we cannot observe objects or events beyond a certain distance.
Furthermore, a large part of the cosmos is made up of dark matter and dark energy, which are not yet fully understood. These components do not interact with light or other forms of electromagnetic radiation, making them difficult to detect and analyze directly.
Despite these obstacles, astronomers and scientists are constantly pushing the boundaries of our understanding. Scientists and space agencies are working hard and being innovative to understand the nature of the cosmos. There are always constant advances in observational techniques, space telescopes, and theoretical models.
We have made considerable progress in understanding the universe, yet still mostly undiscovered. The unsolved mysteries of dark matter and dark energy, the invisible components of the universe, stimulate the curiosity of scientists and inspire additional investigation and research.
