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.

Ducklings in Disguise

You know the story of the Ugly Duckling of course, who didn’t look like his family but grew into a beautiful swan? Well, this is a true story of three little chicks who are going to grow into beautiful ducks, as told by Susannah Leigh.

It all started when my friend Nic’s very favourite chicken, Rosie became broody. Rosie laid some eggs and sat on them very carefully for a very long time. But the eggs didn’t hatch and Nic realised that they were probably never going to. Sometimes they just don’t.

Poor Rosie – all that patient waiting for nothing.

Be a Good Communicator

Have you ever said something that was misunderstood by the person you were talking to? Do you know anyone who sometimes says things in a way that seems rude and abrupt? It is not always the words used, but the way in which they are used.

Good communication is very important. Carolyn Ward explains what it is and how to be a better communicator.

Is Black Really White?

Science will tell you that black is not a colour, rather it is the absence of colour or the fact that there is no colour there. I expect that makes you think of white, rather than black!

And that’s the interesting thing about the word black: it was nearly white. And in fact in several other languages, the same root did develop to mean white.

Stories from the Stables – Part 3 – Ziggy and Ned

At the large livery yard I used to work at, I rode a range of bigger horses and exercised show jumpers and ex-racehorses for owners who were on holiday. Two in particular will always be in my memory as they were both utterly bonkers.
