PART 2: PULSARS, SUPERNOVAS & NEBULAE
Last time I asked a question about place with highest number of G. The answer is Sun. Many of you would know which one was it, but few of you would know how much is it. Its 28 times the gravity on Earth. Yes 20G. It means that as soon a you step on the surface of Sun, all of your blood will be pulled from your upper part of the body into your feets, and you would be crushed by the weight of your 'Hair'. The reason for that high amount of gravity is the mass of the Sun, meaning that higher the mass, higher the gravity. Oh, but that's not it, there's a place with even more Gravity than our Sun.
In the 12th century, there was an explosion and a new star appeared on the sky which outshone any other star in the sky. It was so bright that it was seen even in the daytime. The explosion was the result of a death of a star. Questions arrive that how does a star dies and why.
I'll answer the later first. We all know that the stars are constantly burning, and becouse of the gravity, good amount of energy remains within the star, when the star stops burning, or shall we say runs out of Fuel, the energy within the star becomes unstable, and The Gravity pulls the energy in, thus causing catastrophic result, the Death of the Star.
Now, how does the star dies? The answer is simple! BOOOOOOOMM! Well its not a joke, It is a boom, but the explosion is very bright as if billions of stars had joined together.This kind of explosion caused by the Death of a star is called a SUPERNOVA.
Back to what happened in the 12th century. Well, whatever happened, we may not be able to see that, because now all we can see is this
The Crab Nebula. It is a cloud of different gases like hydrogen and oxygen. All that is left of the star is, crushed into such small size. The core is called the neutron star.
This neutron star being discussed is spinning at rate of 1800 revolutions per minute. As it spins, it ejects particles at the speed of Light, making them a continuous flow of particles, like a beam. These beams can be heard on Earth as Pulses, that is why we call them PULSARS. This star have the gravitational pull of 100 Million times that of Sun. The reason that it has so much gravity is that it has a mass of sun crammed into a a body just 20km in diameter. Thus one can say that gravity is not just about mass, but its about the Volume.
THE PULSAR
Well, all that happened to that star, will happen to our sun, thus ending our world.
Enough about gravity and such huge masses. What about a smaller scale??
Do you know that the our Universe is 99.99% empty?? Stunned?? How is it Possible? Are you 99.99% empty space. Can you see this space. Look at your PALMS for 30 seconds and you will see the vaccum.
OH! YOU ARE LOOKING AT YOUR PALM?? What you are a walking compound microscope!!? :p Of course you cannot see it. But you are 99.99% empty.
More on the way people.
