The existence of dark energy is confirmed

The universe is too light. What?! Well, scientists have worked out how much the universe should weigh and how much substance it should contain, given the weight of matter, the size (height, length and breadth) of the universe and the time of it’s existence.

But, there is a problem. It is too light, and doesn’t have nearly enough substance. It is thought that ordinary matter such as stars, planets and gases only make up around 4% of the total weight of the universe. So where is the rest of it coming from?


That’s what scientists very recently think they have discovered. For a long time now there have been theories about so called ‘dark matter’ and ‘dark energy’ making up the difference, but until now, no actual proof.

However, the results from a major astronomical survey, which used the latest in hi-tech scientific technology and research methods to observe over 200,000 galaxies, appear to have confirmed the existence of dark energy.

The existence of dark energy appears to explain why the universe is expanding at an increasing rate. From what I understand, this is because the energy to some extent almost defies gravity, so if you were to throw a tennis ball, instead of eventually slowing down to a stop, dark energy would continue to increase the speed of the ball.

Scientists now believe that normal matter makes up around 4% of the universes weight, dark matter makes up around 22% and dark energy makes up the other 74%.

We now have some proof of the existence of dark matter and dark energy, however there is still a very long way to go yet, before we discover the true secrets of our universe…

That is if we ever do!

Bye bye Ming Ming

Ever heard of Ming Ming. Chances are you have. Ming Ming was the worlds oldest Panda, and I am sorry to say was.

Aged 34, the Chinese panda Ming Ming died around a week ago. At the time, she was being held in the Xiangjiang Wild Animal World – in Guangdong Province China.

In the wild, a giant panda like Ming Ming would usually survive for up to 30 years in captivity, or about 15-20 years in the wild, due to the more strenuous lifestyle. Ming Ming was the oldest panda in the world at 36, so we are at a great loss to see here go.

It is thought that Ming Ming died of old age. Her organs were deteriorating, and last week this lead to kidney failure for the poor bear.


Ming Ming had a very busy life, she travelled many places including Ireland, the United Kingdom and China. What a panda!

Pandas are an endangered species, with only around 1,800 thought to still be alive in the entire world.

The world has truly lost something special in the death of Ming Ming 🙁

RIP Ming Ming
