A Kid-Friendly Explanation of The Big Bang & An Amazing New Discovery by Scientists
Most scientists believe that the Universe began in a Big Bang around 14 billion years ago. The entire Universe was inside a bubble thousands of times smaller than a pinhead, and was hotter and denser than anything we can imagine.
When the explosion called the Big Bang happened, the Universe as we know it was born. In a fraction of a second, the Universe grew from smaller than a single atom to larger than a galaxy. It kept on growing, and is still expanding today.
Now researchers in America think they have found traces left in the sky that prove this that the Big Bang did really happen. It takes the form of a distinctive twist in the oldest light detectable with telescopes. These twists of light are called ‘gravitational waves’ – the effect is a little bit like how waves form on the surface when you drop a big stone in a pond. However, you also have to imagine that the Big Bang formed the pond itself.
The team leading the project, known as BICEP2, has been using a telescope at the South Pole to make detailed observations of a small patch of sky. The aim was to find evidence of ‘inflation’ – the idea that the cosmos grew rapidly in its first trillionth, or trillionth of a trillionth of a second – growing from something unimaginably small to something about the size of a marble.
The leader of the team, Prof John Kovac of the Harvard-Smithsonian Center for Astrophysics said:
“This is opening a window on what we believe to be a new regime of physics – the physics of what happened in the first unbelievably tiny fraction of a second in the Universe.”
Over the coming years, scientists will work hard to investigate every aspect of this discovery. Other experiments will be carried out to see if they can replicate the findings of the American team. If this research is confirmed, it will be one of the greatest scientific discoveries of our time.

A Poem – Sadness is a Storm
This poem was sent to us by one of our talented young readers, 14 year old Rebekah.
Sadness is a storm.
A clap of thunder,
As you howl and wail,
Yet through it all,
You still prevail.
Nothing withstands
The heart of the tempest.
Ominous clouds loom,
Lightning flashes.
Light still gets through.
It gives you a glimpse,
Of hope pure and true
All’s well once more,
With the subsiding of the storm.

Do You Hate School Uniform? – Written By You
My name is Daisy, I’m eleven years old and although I am English, I have lived in Germany nearly all my life! I speak German and English and can read and write both too. I enjoy writing and listening to music and am the middle child of three. My mother is an author.
Does your school have a school uniform? Having to wear those scratchy skirts? Tight stockings? With our normal clothes, you can show what kind of person you are! You can send a message out to the world with how you dress, what makeup you were and how you have your hair done!
School uniforms are stopping all this. Not being allowed to choose what to wear seems so unfair! Wouldn’t it be fair if we could choose if we wanted uniforms or not? People are debating on school uniforms and deciding if they should stay!
Great Women You Should Know: Betty Skelton
In our series of Great Women You Should Know … here comes daredevil and adventurer Betty Skelton
When she was eight, Betty fell in love with aeroplanes. She watched them flying over her house every day, she devoured books about them, and she begged her parents to take her to airfields where she would persuade pilots to take her on rides above the clouds.
Betty must have been a very persuasive person, because she also talked a young Navy pilot into giving the whole family flying lessons. And when I say whole family, I mean it: Betty flew her first plane solo when she was just twelve years old. She might have been a tiny daredevil, but she was so scared her mother would scold her for doing it that she kept it a secret for a week!
