Introduction
People have been studying the wonders of space since the 4th century. As time passes, many have found astounding discoveries and found the answers to countless questions about our universe. But, outer space still has numerous questions where it is nearly impossible to answer that even scientists are struggling. Questions like ''what came before the big bang?'' ''whats inside a black hole?'' ''are we alone in the universe?'' are quite difficult to answer and why scientists (more specifically astrologists) have these things called ''theories''.
Why should we learn about space and our solar system? It's really good to know what is outside of our earth and where we live. Space is our past, present and future and could play a significant role in the future. Who knows? Maybe before earth explodes, our friends named ''aliens'' can actually save us and bring us to a new planet to live in.
LETS LEARN MOREEEEE!!!!!!!!!!!!
Task
There's a lot to talk about when the subject is space. Planets, stars, galaxies, gravity, big bang, solar systems and more and more and more. Right now, we're going to get into black holes.
Black holes are areas of space that have such strong gravity, nothing can escape them. Not even light waves can escape from them. They just pull things close and then suck them in. What happens after, no one can say for sure. Scientists still don't know what's inside a black hole and are still trying to figure out.
Do you remember when you looked up at the night sky and you see those beautiful twinkly things up there. Yeah me too. We know them as.................. STARS!!! A star is a huge and bright object which is made by a very hot gas called plasma. It is held together by its own gravity. Fact! (You probably already know this) the Sun is a star made up of different types of gases; mostly hydrogen and helium.
We all know what the Big Bang Theory is, right? And no, I'm not talking about the tv show. The Big Bang Theory is a theory where a HUGE bang happened and that the explosion continuously expanded. Throughout that whole expansion, space, time, energy, matter and then, stars, galaxies, humans, etc., came into existence.
Process
FUN FACTS ABOUT SPACE THAT WILL MAKE YOU BE LIKE ''WOOOAH''!
1. You Can't Hear Anything In Space
That's right. You cannot hear anything in space. The reason behind this is because in the empty - regions of space, where there is no air, sound has no way to travel. Sound waves travel through air, and obviously there is no air in space so boom there you have it folks
2. One million Earths could fit inside the sun
– and the sun is known to be an average-sized star.
3. There are more stars in the universe than grains of sand on all the beaches on Earth.
THAT'S A LEAST A BILLION TRILLION STARS!!!
