You may think that combining spaghetti and ice [cream], that it must have been invented in Italy, and you are almost right. It was invented by a man called Dario Fontanella, the son of Italian immigrants in Germany.
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.

Dr Sarah Bearchell drew our attention to this video, which explains the concept of gravity and gravitational waves with the help of a towel, an apple and a ping pong ball. Check it out
Lions are felines, which means that they are members of the same wider family as cats. Indeed, they are frequently referred to as “large cats” or something similar.
They live on plains and savanna in Africa and India, where the sun beats down on the grassland so that it fades, withers and turns yellow – just the colour of a lion, which helps to camouflage it, so that it can blend in with its surroundings and stay hidden.
Alice M is 10 years old, and has some great advice on being a girl
The Joy about being a girl is you get more opportunities because people mostly trust girls better than boys. I know that it majorly sexist but technically that is what happens in life.
We all know that girls have to go through a HARD time when they are older but it is sometimes worth it, GIRLS are the ones that actually produce the baby, GIRLS are the ones who have super fashion sense and are the ones who are unique with any kind of style Goth, jumpy, and get have any personality they want to and we wear make-up to make ourselves look nice, scary, horrible anything you want, we can style hair, have fun and mess around.
Some people don’t like being girls mostly because their scared, I am too, but if you think about it there generally is nothing to be afraid of. You have people all along the way to help you enter adulthood and become bigger and better, people will help you when it is hard and when you need constant monitoring but after all that has passed, I will guarantee that you will have had the time of your LIFE being a girl.
So what I am trying to say is: enjoy being a girl, enjoy having horrid things done to you (I know that sounds backwards but trust me, it I’ll be worth it) because when that is all over you’ll miss it.
