The Universe is about 13 billion years old and yet no one actually knows how the universe was made. That's because no one has actually been at the beginning of time. We can theorize but we will never actually know what started the creation of the universe. But because we know that the universe is expanding, we can probably say the it once started out smaller than anything there could probably be.
What I know of is that for some unknown reason, the universe started out with a bang. A very big bang. Out of nothing, absolutely nothing, the universe came to be. It expanded from a dot as small as a quark(what atoms are made of) to something the size of the Earth in less than a second. At first, it was only matter and anti-matter. If they touch each other they will go into non-existence. After this war, matter won, and that's why were not made of anti-matter.
The only element present was hydrogen, the lightest of all the elements. But, gravity took over and the hydrogen bonded with each other and created the first stars. In the star's core, nuclear fusion is happening making heavier elements like gold and other rocks. Millions of years later, when a star dies, all the elements in it's core is ejected out into space which is what our planets are made up of. This cycle of making stars, making more elements and dying is what has made all our planets and even what your using to read this right now. So in a way, you, me, and everything is made up of star material o.O. And this cycle is still happening. Stars are born, die and make new planets and stars. So that's what has happened from the big bang, as far as I know. I could be wrong.
Paul ! I'm so impressed on how you know al this science stuff ! I am really interested in all of it. This is something I've actually been wanting to know about , and here it is ! Just a question , why did you chose to science topics about th e world and all. Keep up the blogging (:
ReplyDeleteCoool!!! I never knew I was made out of a star lol. So how did the big bang even happen? How can you make a explosion out of nothing?
ReplyDeleteFirst of all, I was always into Science, especially, space. I always see these documentaries on TV and on youtube. I just love knowing about the world and how it works, well, the whole universe. One thing I just want to say, did you know that we, on the earth, only have about 140 Yottameters(About 14 Billion light years[a lot]) of viewable universe. That means the we cannot see further than that as of now, until time progresses. Also, the Universe is about 900 Yottameters or 93 Billion lightyears.Second, nobody actually knows how the Big Bang started. It might have been from the touching of two outer Universes(The Many Universe Theory) or other causes. The Big Bang might actually be absolutely wrong. As I said, we might never know.PS:I'm on my computer, that is why I was able to type as much.
