Introduction to space

Space is an area of vast matter that has no gravity. It is believed that a big bang formed space. Lots of parts are still unknown by humans, and scientists are trying to figure out them. But all we know is that space is endless. Even at the speed of light, we can never reach it. There is a area of the universe we can see and that is called the observable universe

Space is important since the sun and earth are in space so without space we would simply not exist

To put is simply yes. There is a portion of space called the observable universe which is 46.508 BILLION light years away(4.3519360 x 10 with 23 more zeros km away)And scientists estimate the universe is at least 250 times bigger than the observable universe

The universe is a vast space of nothing.But what is the universe made of. Well, the known universe known is about 4%.Dark energy, an unknown thing, fills up 23%. So, what makes the remaining 73%. Well, an even more mysterious thing called dark matter fills it up/
