In the Animal kingdom, the Ladies are the ones you should look out for.. They do most of the Hunting and Foraging. They do half of the Fighting. And still make out lots of time for the Kids and care for the Family. This SuperMum Cheetah is a great example of how all the Mothers... Continue Reading →
wow. this is a Great Read. The Auroras have always awed Man. Its so beautiful and even more when we learn how they came to appear in the first place. 🙂
A snappy little post today, the science behind the spectacular display of the Aurora Borealis a.k.a Northern Lights. This mystical display of colours may be better left to childhood imagination but in the name of science we shall explain its true origin. As with many things here on Earth, the existence of the Northern Lights is thanks to the Sun. The Sun may be million of miles away but the effects of this colossal heat giant can be easily felt on our planet.
Storms on the Sun blow out streams of electrically charged solar particles across space and the Earth is in the path of this stream. The solar wind, as its called, distorts the Earth’s magnetic field and allows charged particles from the Sun to enter the Earth’s atmosphere. This is most easily done at the poles of the Earth where the magnetic field is weaker which is why…

I'm so sorry I couldn't post a thing throughout the Christmas season. But its never late to write. And I wish us all a very Happy and Wonderful New Year. 🙂 I didn't know what to start off the year 2017 with, until I came upon this little something I wrote two years ago. Its... Continue Reading →
A lot of concepts or rather subjects of probe in the world often have two sides. One for and one against. Most times, I try putting myself in both shoes to see things from their own unique perspectives. As to the case of the centre of the universe, or how the Earth came to be,... Continue Reading →
Three years ago, I was going through a NASA website, following a trend in an argument that once took place a long time ago. The argument having ensued for many centuries, during the growth of astronomy. However, I brought this up now because, sometime this year, some group of people calling themselves the Flat Earthers...

NASA recently released this astounding Photo of the far Universe; as seen by Hubble. Here's a Piece I read from Douglas Preston's book, Impact. "The Universe is a hundred and fifty-six billion light-years in diameter, and that's just our part of it; the part we can see. The Human brain can't imagine the Universe.. The... Continue Reading →
The Script of Galadriel, Lady of Light. I figured i should put this up here, having being a Middle-Earth citizen since the year 2001, when I first came across the motion pictures of J.R.R. Tolkien's LOTR- Fellowship of The Ring. The prologue is quite a favourite part of the film for me. All lines below... Continue Reading →
The Saga of the 2016 Supermoon has come and gone. Night on the 14th of November 2016, the Moon was closer to the Earth than normal and shone the brightest since 1948. The phenomenon, called a Supermoon, happens when the moon is full at the same time that it’s orbiting at its closest point to... Continue Reading →
Now I understand the Fermi Paradox better. 🙂
Part I: The Question
The most simple questions that we can ask often turn out to be the biggest. Physicist Enrico Fermi is testament to this with his big ask ‘where is everyone?’ Where is everyone in the vast universe, why do we hear nothing but silence when we scour the night skies, where are all the aliens?
When we look up a particularly starry night sky we are only observing a very small proportion of the stars in our galaxy. Which in itself is a very very small proportion of the stars in our observable universe (note. observable universe, and that’s just the part closest surrounding us that we can receive light from!) Let’s throw some numbers into the mix.
Part II: The Calculation
There are 100-400 billion (yes billion that’s 10^9) stars in our Milky way galaxy. Now astronomers believe that there are roughly 100 billion galaxies in…
