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 it Like to Be an MP?
In May 2015 life changed dramatically for 182 British people and their families, when they were elected Members of Parliament in the General Election. We asked MP Kirsty Blackman, MP for Aberdeen North, how her life has changed since the election, and what it’s like to be an MP.
Talking in Text
Text speak is very confusing for a lot of people, but it is one area in which children and teenagers are far more advanced than adults. Mobile phones and the internet are recent inventions.
Imagine what it was like for your parents as children. If your parents are 30 years old, the internet did not exist for them! Mobile phones were only invented in 1973 but did not become common for 15 or 20 years. The first ones cost thousands of pounds and were the size of house bricks!
The UK General Election – An Explanation for Kids
Every five years, United Kingdom elects a new parliament. This is called a General Election and it’s pretty complicated. If you’ve ever wondered how a country decides who is going to run things, this is how! We asked our contributor Tina Price-Johnson to write an explanation of the General Election for kids.
When I was in Year 9, my school ran a mock general election, so we could learn how an election works. I was chosen to be the Liberal Democrat candidate, and two other students were chosen to represent the Conservative Party and the Labour Party. We didn’t have any other parties at that time!
We had to pretend we were running to be elected as a Member of Parliament (MP), and the other students in the school were the voters. We created posters and learned what each party stood for, so we could debate in front of the whole school and give our speeches. We spoke to students in the hallway, and each of us had a team of other students to help us out. This is exactly what all the candidates for MP in your local area will be doing. More or less!
