Cat’s Bats
Cat is 10 years old and has recently moved back from living abroad. She is settling into school in UK and learning to read and write in English (until now she was schooled in French, so it is a bit of a change). Her favourite animals are bats, and here she tells us a bit about them.
A Controlling Friendship – A Bully By Another Name
Have you ever had a friend who made you feel bad? Maybe your friend was mean to you sometimes, and confused you. Or she (or he) would ignore you because you had done something wrong.
We all fall out with our friends on occasion, even us adults. It is a normal part of life.
When the friendship is one-sided then it is a different story. Then we might say it is a ‘controlling friendship’.
Great Women You Should Know… Helen Sharman
Dr. Helen Sharman, the first British astronaut and at 27 the fifth youngest person to be launched into space on the 18th May 1991. Our contributor Annie May Gibbs had the opportunity to meet Dr Sharman and ask her some questions.
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.
