Since the beginning of civilization, mankind has been constantly fascinated by what’s beyond our world. We have always looked up to the stars to seek our place in the vast emptiness of space. And with modern inventions starting from the 20th century, we have been on a quest to the stars. And here’s what we have found out about the universe.
The Universe’s Vastness
What we see in the night sky is just the tip of the finger compared to the whole universe and many other universes as revealed to us by science. It is difficult to comprehend just how big space is. It puts everything into perspective and gives us an existential crisis when we think of how small we really are compared to what’s out there.
The Big Bang Theory
Not the television show, but the theory that everything started with an explosion called the Big Bang. For believers of science, this is the most widely known theory to explain the universe and our beginnings. According to scientists and astronomers, the Big Bang came about when all matter and energy were compressed into a singularity, or a point of infinite density and temperature about 13.8 billion years ago. Then it all went with a bang and made the universe.
Cosmic Objects
No matter how beautiful the twinkling stars of the night sky look, we have to remember that there is a reason for it all, at least that’s what the scientists believe. There are so many awesome things in space that continue to baffle us. There are black holes, quasars, pulsars, supernovas, and many others that scientists continue to study to this day.
The Search for Life in the Universe
Aliens have always been at the forefront of anything space-related. It might be our natural curiosity as humans, but many people believe that aliens are real. With the vastness of the universe, it is possible that Earth isn’t the only place hosting life. There are many other planets that we haven’t explored yet, with our limited resources and technology. But if you believe they are out there, we won’t judge you.
Dark Matter and Dark Energy
You might have heard of the term “Dark Matter” from your favorite fantasy movies or series, but it is not wholly fiction. Scientists theorize that dark matter is a substance that does not emit light or energy, but exerts a gravitational influence on galaxies and is thought to make up a significant portion of the mass of the universe. Dark energy, on the other hand, is believed to be a mysterious force that causes the universe to expand.
The Expanding Universe
One of the most popular discoveries in astronomy and cosmology is that the universe seems to be expanding. This is evidenced by galaxies moving away from each other. Our scientists have observed this phenomenon by looking at the stars through high-powered telescopes over a period of time. If this is true, it might make the Big Bang theory true as well, since it proposes that when the universe started, it might not have been as big as it is now.
