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.

What is Roller Derby?
You might have heard of Roller Derby but still be asking yourself, ‘What is Roller Derby?’.
It is a sport that originated in the USA in the 1930s and has evolved over the last eighty years. The modern version of the sport is fast, fun and mainly by girls and women. Joanne Brady has been finding out a bit about the sport and the women who play it.
6 Things Kids with Special Needs Wish EVERYONE Would Do
When we published our article 6 Things Parents Wish Their Kids Would Do … and 6 Things Kids Wish Their Parents Would Do, one of our readers got in touch to say we should do one for the things that kids with special needs wish EVERYONE would do. So we asked our followers, and came up with this list.
It was a bit tricky to put the list together, because there are so many different kinds of “special needs”. For some children, their disability is quite well manageable with medication, or with assistance and therapy, and you’d hardly know they had any additional needs. You may have heard of autism or Asperger’s Syndrome – these are part of the autistic disorder spectrum, a range of conditions that affect how people communicate and relate to people around them. You can’t tell by looking at someone if they have ASD.
Other children have disabilities that are apparent when you meet them, such as those with Down’s Syndrome, which we have covered in more detail here. Or they might use a wheelchair to get around.
What thing do they all have in common? They sometimes get asked really silly questions, and get treated badly by people. Make sure you aren’t one of them, by listening to what the kids (and their parents) had to say!
Amazing Outdoor Art
A few weeks ago on Twitter we shared a picture of an electrical tower that German students had turned into a stunning 3D stained glass window. This got us thinking about other amazing outdoor art a little bit closer to home. Read on for some inspiring examples that you can go and see for yourself…
I, Coriander by Sally Gardner – Book Review by You
This book is set in 1649, just after King Charles 1st had been executed. At the back of the book there are some historical background notes.
It is really hard to describe, because although it is set in a real time from history, it moves between two different worlds, it is unlike any book I have read before.
It is the best book I have ever read, I couldn’t put it down and read the 300 paged book in two days. It is packed full of mystery, magic and adventure, and history, with the slightest bit of romance.
The story unfolds through the eyes of six year old Coriander, who is almost 20 by the end of the book. One of things which is fun seeing change, is Coriander’s fear of the stuffed baby alligator in her father’s study, it holds the key to the cabinet in its mouth, and at the end, it comes alive (just like she had feared all along) it saves her-I can’t tell you how because it will spoil it!
The imagery throughout the novel is beautiful, and everything is described in great detail. Here is an example:
” Everything in the room was covered in a layer of thick dust. The curtains that the sun had been badgering were now no more than a mass of spiders webs. The bedroom covers were all torn and tattered, feathers split from the mattresses, and the wash basin was cracked and broken as if long abandoned. It was a room of rags and feathers, nothing more.”
The book has a fairy tale quality to it, because of the language Sally Gardner uses and the events of the story.
The characters are larger than life and dramatic, and at times frightening.
This novel’s ending was satisfying and felt complete. After reading this book I felt inspired to write a story set in a time from history also. One of my favourite things about the book, is how Coriander stands up for herself.
I highly recommend this book, I will definitely read it again!
I rate it 10/10, and would recommend to age 9-14
