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.

Gentry or Servant? Which Would You Choose To Be? – Written By You
You will all know what a ‘servant’ is, I am sure – Perhaps your Mum says that sometimes when you ask her to do too much for you ‘Do you think I am your servant?’ 🙂
Do you know we mean when we say ‘the gentry’? According to this website
The gentry were the people who were knights, squires, gentlemen and gentlewoman whose fortunes were great that they did not have to work with their hands for a living. Their numbers grew rapidly and became the most important class during Elizabethan time. They could start as a knight and through generations and marriages, they could gradually build a wealth and title. Most of the important people of this time came from this class.
Back in Tudor times (between 1485 and 1603), a person couldn’t choose to be born into the gentry. Today groups of people all over the world get together to reenact various periods of history, including the Tudor period.
Alison has been on both sides of the gentry/servant divide and tells us all about reenactments, making your own clothes and living like a Tudor girl, at least for a weekend.
