SHOW NOTES:
Stars are like fiery hot balls of gas, held together as one massive globule with the help of gravity. Like humans, they are born, have a finite life time during which they age, and finally die. The initial mass with which a particular star is born, decides how it evolves.  Take for example a star like the sun, whose mass is roughly 2 times 10 to the power 30 kg, that is, 2 followed by 30 zeros. It fuses hydrogen to helium for a few billion years.  During this period,  gravity tries pulling all the matter inwards while radiation, from burning hydrogen, exerts pressure outwards, that is in a direction opposite to that of gravity. The burning of Hydrogen keeps the tug-of-war between gravity and radiation going. As the amount of hydrogen starts decreasing, the star grows into a massive red giant. As the name suggests the star has a reddish colour and grows in size because of the thin layer of Hygrogen that surrounds a small helium core. In fact, when our sun becomes a red giant, it will grow so big in size that it will engulf all the inner planets of the Solar system, including the earth. After all the hydrogen fuel gets exhausted, gravity starts over-powering the outward radiation pressure, making the ball of gas collapse on itself. This is when things start getting exciting and stellar fates diverge.  For sun-sized stars, the core starts collapsing while the outer shell starts expanding and is eventually blown away leaving behind a white dwarf star, that is hot, less luminous and nearly the size of the earth. For stars, born with roughly twice the mass of our Sun, the cores collapse further. They undergo a massive expsion called a supernova and end up as neutron stars, that are roughly the size of a small city with a 10 km radius. A different kind of pressure, called the Fermi degeneracy pressure, exerted by fermions that are particles like electrons and neutrons, prevent White Dwarfs and Neutron stars from collapsing further. But what if there is a star that is really really massive? Such stars, with masses many times the mass of our sun, explode brilliantly and finally form a black hole. No kind of pressure can counter gravity in black holes. Even light, or more generally, electromagnetic radiation, cannot escape from these notorious objects. 
When you look up at the night sky and see the countless number of stars, remember each star has its own story!

Finding Faith

Wrecked Again (2013 Remaster)

Shuffleboat River Farewell (2013 Remaster)

The background music belongs to Monocle Twins. I just composed the lyrics. Ok Feel free to leave your feedbacks. This one touched my heart. I  can't sleep by thinking how to sing the lyrics.

This is the lyrics.

Everything that you've done today
Soon will be a memory
The kindness that you did today
The person that you helped today
The purpose that you have today
Soon will be a legacy

All efforts that you've worked today
You work hard for something today
You endure to fight for today
Soon will be a victory

You are thinking for tomorrow
Live for now and don't worry
You regret you did a mistake 
Let go and don't feel sorry

You are dreaming to do something
Don't give up and keep trying
You are feeling down coz you failed
Soon you will be a winner

Bridge:

Whatever goes on we are in this kind of battle
(Don't feel to give up)
You promised to win but this time you are failing
(Don't feel to give up)(To give up)

Chorus: 
You are thinking that you did your best
(But that's not yet enough)
You are thinking that you got everything
(But you feel you have nothing)
You are feeling tired and you want to give up
Don't loose hope the best has yet to come
And that's the road to life

You can't change what's meant to happen
Oh please leave the past behind
Your fears makes you feel that you loose
You can overcome your fears
You have doubts to deal with yourself
Please don't think more about them
You don't meet the expectations
You are more than what they expect

Bridge:

Whatever goes on we are in this kind of battle
(Don't feel to give up)
You promised to win but this time you are failing
(Don't feel to give up)(To give up)

Chorus: 
You are thinking that you did your best
(But that's not yet enough)
You are thinking that you got everything
(But you feel you have nothing)
You are feeling tired and you want to give up
Don't loose hope the best has yet to come
And that's the road to life.

You are thinking that you did your best
(But that's not yet enough)
You are thinking that you got everything
(But you feel you have nothing)
You are feeling tired and you want to give up
Don't loose hope the best has yet to come
And that's the road to life.
