In our previous article we spoke about the beginning of everything; Everything started with the Big Bang. Now we ask ourselves what happened after and if it has an end. Our universe has been there for a very long time. About 13.8 billion years (that’s 9 zeros after 13!), so what happens now? Will our universe be there forever? With all the astronomy we have learned till now we will try to answer a few questions and in the process make new ones.

Let’s start by saying that our universe is like a big balloon with many dots. As we blow air into the balloon, the dots move further apart. Here we present our first case.
For understanding the next part, let’s do a thought experiment. Imagine you have hot water, a plate and a glass. You pour hot water onto both glass and plate. Which water will cool first?

Why?
One way to understand this at basic level is to know that more spread out something is, faster it cools. Now let’s come back to the universe. Our universe which is a balloon is getting big; our dots are moving apart. Therefore, things are spreading apart as our balloon universe is getting bigger and bigger. And from the thought experiment we know that this will make our universe colder and colder. And what happens when you cool things too much? They freeze. This end of universe is called Cold Death.

*Fun Experiment:*
Take a balloon. Draw some dots on the balloon. Now blow air into it. You will see that the dots move apart as you blow more and more air into it.
Treat this as an analogy to the Expanding Universe

A long long time ago everything we see and feel around us like gadgets, automobiles, houses, plants, our environment at large and even the Sun was no bigger than a tiny little seed. This seed was made of pure energy. One day this seed exploded. It was the brightest explosion ever, called the Big Bang. It was the beginning of our world and the beginning of time. This seed as it exploded got bigger and bigger like a balloon. As the balloon got bigger things started changing. For a period of time there was no light in our world and this period was called the dark ages. Then the first light from the explosion, lit up the world. […]

It used to be said, that an idle mind is a devil’s workshop. In the olden days, this applied a lot to the child who, due to sheer boredom or for want of anything else to do, would resort to naughty or mischievous ways and, duly get into trouble. But then, those were days when gadgets didn’t occupy his mind, when the three R’s would keep him busy and, only if his leisure hours were not planned well, the ‘devil’s workshop’ would get into an overdrive mode. […]

In the formative years of a human being, there are many aspects that must be taken into account, to ensure that, in later years of adulthood, the foundation so laid, will form a strong combination of body, mind and soul for a healthy life.
While it is possible to see the ‘body’ and how the physical form develops into a seemingly healthy shape, the other two unseen aspects of the trio – ‘mind’ and ‘soul’ are elements that can only be tuned by proper training, tutoring and discipline. […]
