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.

What is the Difference Between Introvert and Extrovert?

What is the difference between introvert and extrovert? And which one are you?

 

What does an INTROVERT look like?

Introverts tend to be people who are most comfortable in their own company or spending time with a small, familiar group of friends. They are analytical in their thinking, like to have all of the available facts to hand before making a decision and are probably a little bit uncomfortable when forced into the limelight. Introverts think before they speak.

 

What does an EXTROVERT look like?

 

Extroverts, on the other hand, think as they speak! They’re happy to take centre stage, love to talk about anything and everything that comes to mind, are happy being part of a large group and make fast decisions. Extroverts are less happy in their own company and tend to get bored without someone around to keep them amused.

In short, introverts are often described as being energised by enjoying time spent alone with their thoughts, whereas extroverts recharge their batteries by being in a roomful of equally extroverted people!

Explaining History – And Firing a Steam Train

Have you ever watched someone at work and wondered how they got there, or why they do what they do all day long?
Laura works as an explainer at the UK’s biggest train museum – the National Railway Museum in York. It may seem that steam trains and young women do not go together, but Laura loves it. She spoke to Joanne to explain how she became an explainer, and what she does all day.

Why Do Americans Refrigerate Eggs and Many Other Countries Don’t?

Why do Americans Refrigerate Eggs

If you’ve ever been to USA, you will notice that they sell eggs in a different area of the grocery store than in many other countries. We are used to finding our eggs stacked on shelves, often near the baking supplies, but Americans refrigerate eggs in their stores. Find out why they do this, and how to safely prepare egg dishes.
