THE BIG BANG
Let’s start this blog off by talking about the Big Bang, a widely accepted theory by most physicists that describes the origin of our universe. No, the Big Bang wasn’t a giant explosion, as fun as that sounds, but it was more about the universe expanding into what it is today! Would you believe that the energy of the universe - the same energy that’s behind stars, galaxies, and planets - was first confined to a space smaller than an atom? But this is where our story starts: about 13.8 billion years ago, when the universe was still just a hot soup of particles whizzing around, filled with energy. Then, along comes the Big Bang: a rapid expansion of the tiny particles, as everything inflated and stretched while cooling to lower temperatures at the sametime. New particles formed, and then slowly atoms came into existence. Matter turned into galaxies and stars, and from just about nothing, the universe quickly expanded into the infinite realms of space and continues to expand even to this day.
But the most fascinating thing about the Big Bang isn’t just that it explains the mysterious galaxies, beautiful stars, and enormous planets that we have today. At the end of the day, the Big Bang is just a theory – it’s backed by evidence, but there’s many other ideas out there that try to explain the origins of our universe.
Even to this day, the beginning of our universe is still an enormous mystery, and because the universe itself is so vast, that means there’s many other hidden secrets still waiting to be discovered. But, with curiosity, dedication, and a dash of imagination, we can get closer and closer to understanding the existence of our cosmos. So tell me, what will you discover?
