Blogpost 1: The Big Bang

Have you ever wondered where all the things around you came from? How or why were they like that? When you look up in the sky, have you ever thought of going higher and higher to see what's up there?

Well I think all of us does. Now let me give you a thought of where everything started.

 The Big Bang, scientists say that all things in the universe came from one single planet and  exploded then

inflated to the cosmos to create galaxies, stars and planets. This explains the origin of the universe, and where did Planets and Stars came from. But still, through the discovery of the big planet, they question things like, "how did it come into existence, and what existed before it?"

An article I've read entitled, The Origin of the Universe written by John P. Millis from space.about.com stated that scientists then believed that the Universe had no origin because they thought that it was eternal. Until they discovered a microwave signal called the Cosmic Microwave Background (CMB). This signal began the theory of the Big Bang. That the Universe began in from a singularity then inflated from small, very dense, and very hot by the speed of light to the coldness of space that we have known by now.

The CMB is a signal detected that they believed that was the echo of the big bang. It was some kind of a "heat signature". Also, they added up the fact that the universe is receding from us, meaning it's expanding. Imagine it like a bomb just exploded in space then the particles were just floating then because of the force given by the bomb, the particles just scatter away from it's center of explosion. That was the logic given from this theory.

But scientists still wonder what started or what was the Universe back then, before the explosion, before the big planet. Was there an older Universe that compressed in the middle of it to form a big planet? Or just an empty space, then objects suddenly appeared.

   A guy named Sean Carroll from the article  The Big Bang: What Really Happened at Our Universe's Birth? from space.com said that, "It could just be empty space that existed before our Big Bang happened, then some quantum fluctuation gave birth to a universe like ours." It says there that it may just be an empty space then a single object was filled with energy. Like, imagine a molecule absorbing and getting energy then suddenly became big then created a great mass. But there are still questions that come to mind like, where did those energy came from? Alex Filippenko an American astrophysicist also stated that, "I think time in our Universe started with the Big Bang, but i think we were a fluctuation from a predecessor, a mother Universe." Meaning that there maybe is a Universe back then, a Universe that may just be unfixed then somehow fixed itself to create a new one. We may not yet conclude that this was the beginning of everything yet Sean Carroll quoted:

"We know all these things now.", "The pace of progress is actually astonishingly fast, so I would never give in to pessimism. There's no reason in the recent history of cosmology and physics to be pessimistic about our prospects for understanding the Big Bang."

This was so a great discovery for scientists. It didn't just answer their questions, but they also revealed and contributed a great thing to the world and its people. If they didn't brainstorm or tried to solve this great thing that they discovered, we would all still be wondering where did all things from the Universe and from the Earth came from. 


It's really hard when you investigate things without enough evidence. Especially when you're investigating from a 13.8 billion year event. We don't know much, we did not see the exact explosion, but I believe that our modern scientists and our use of modern technology can enlighten what really happened in the big bang, or did the big bang really happened.

This study really made up my interests about space. But my question personally is, why are we created like this? Why space? Why have other galaxies? Why were we made as humans not aliens or where did we really came from? And are we exactly a part of the big bang. But I am thankful, that this explosion they explained, gave us a beautiful world.
