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.

Last Minute Homemade Halloween Costumes

What’s your favourite holiday? Christmas? Easter? Or is it Halloween? The day when we let our imaginations run wild and, instead of feeling that we have to prettify, we are encouraged to look as disgusting as possible.

I love Halloween, I love getting dressed up and playing games. I love bobbing for apples and grossing everyone out. Once upon a time we just threw on a sheet with eye holes cut out, those days are long gone. Now we consider our costume choices carefully. We co-ordinate, we plan and we get excited. You don’t need to spend a fortune on fancy costumes though, nor do you need to be an expert face painter. Here are a few ideas to get you started.

Living in History

Now you know what reenactment is, from Alison’s excellent article, you may want to know a bit more about how it all works. How much work is involved in sewing the clothes, what do they eat, how do they get around? Alison’s mother Jax has written a great article about all this and more

It wasn’t an easy life, living in Tudor times. You can find that out by reading about it in a variety of places.

But I found it out by living it at Kentwell Hall.

We do reenactment. We being our entire family, from my son who was a Tudor baby aged 4 months last summer, through to my partner Tim.

Woolly Hugs

Sometimes sad things happen, and when that happens we need a hug.
Sometimes sad things happen to people we know, and we offer them a hug.
Sometimes sad things happen to people we don’t really know and we feel helpless. We want to offer comfort but don’t know how. We want to hug them, but they are too far away, or not really good enough friends so that we feel we can offer a hug.

Pride of Place – The World of the Lion

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.
