A Kid-Friendly Explanation of The Big Bang & An Amazing New Discovery by Scientists

kid-friendly explanation of Big Bang

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.

Exploring Australia – Marvellous Melbourne

melbourne lanes

Continuing on my Australian adventure, I thought I’d tell you about Melbourne, my new favourite city. Whilst I’m in Australia, I’m going to be staying here in Melbourne, then moving on to Sydney next week. Sydney, I know about; there’s a big harbour, famous for its bridge and its opera house. But Melbourne? Before I came here, I didn’t know a thing about it.
 The first thing I found out is that Melbourne is in the South East of Australia, in the state of Victoria. It’s on the coast and like Sydney is a harbour city. The climate in Melbourne can be a bit like the UK; it changes often and can start raining out of nowhere! Although it gets hotter than the UK, it doesn’t get quite as hot as the rest of Australia.

JUMP! Around the World – Ayşe in Turkey

Have you ever wanted to know what it is like to grow up in another country?
We continue our Jump! Mag tour of the world in Turkey, where seven-year-old Ayşe lives.

 

Hello Ayşe, How do I say hello in Turkish?

Merhaba Annie!

 

What are your favourite subjects at school?

That’s hard… I think most of all I like learning Turkish language and…….music.

 

What kind of music do you like listening to?

I like to dance to pop music like Rhianna and Adele but I like Turkish music too, I like a rock band called Duman.

 

What games do you like to play with your friends?

Mostly street games like Tag and hide & seek, it’s fun to chase each other around.

 

What do you like most about being a girl?

…….I think maybe because…you can have a baby… Also at school at playtime, the boys are always chasing each other and fighting and being a bit rough, and they can be like that with each other but not with us, they can’t be so rough with us. I like wearing dresses also and dressing up!

 

What are your favourite words in your language?

I love you…….mum.

 

If you could choose any country in the world to visit, which would it be and why?

I want to go to America, to  visit my Aunt in San Fransisco, I want to swim in the sea in Mexico because my Mum has told me all about it. I’d also like to go to Africa, to visit the different native tribes that live there.

 

How would you describe your village to someone who wanted to visit here?

I live in a fishing village, it is very sunny, there’s no snow here! We have the sea, which I like to go swimming in and I like to go walking up around the mountain near the sea which is beautiful.
