And, The Journey continues

Now that we have seen the collision of two galaxies it’s time for us to move ahead and further into the dark space in search of the edge of universe. I have changed the coordinates of Nautilus and we are heading towards our neighboring galaxy Andromeda. We won’t go much deep into the galaxy as there is a chance of getting sucked inside it’s super massive black hole. I see a small cluster far in the Andromeda Galaxy. It has vibrant colors, shades of blue, green, yellow and red much like clouds and small twinklings within it like stars do. We are heading close towards it. The outside seems to be smoggy, colorful though, like we are into some enchanted place of fairies with a strange fear of getting lost or devoured by some beast. Are we even allowed to view such beauty from up so close? 
There are some asteroids zooming past us and those twinkling star not so friendly up close. They are hot gaseous bodies, balls of fire, not as big and bright as our Sun. The sensors of Nautilus tells me this place is abundant in Hydrogen and Helium with some other ionized gases. The dust spread out over a large space signifies that as if some explosion took place here. This dust and gaseous material are leftovers from an explosion for sure. But what could have exploded here, A Star? Definitely yes, when a star ages it becomes weaker, brightness reduces and makes it dim, less hot object. The Gravitational pull although remains more or less the same. The outer surface of star becomes weak and unstable and slowly the inner gravitational force becomes stronger than that. This causes the star to curb to its own weight. The star gets compressed falling prey to its own gravity. The outer surface breaks and compresses as a result the star gets smaller in size. After a point of time the star is so highly compressed that it’s no bigger that full-stop at the end of this sentence. On other hand the compression causes an extremely high amount of energy localized into one single dot. The atoms of hydrogen and helium are unstable within it and begins to collapse. The atoms colliding at higher rate due to the compression cause that tiny single dot to become more and more violent. Consider a bomb compressed in a very small box and left to explode. Imagine the intensity of that explosion, something similar happens here at an unimaginable rate. The unstable star explodes with all its energy, million times powerful than atom bombs.This explosion is also known as Supernova. Anything that comes in it blast radius will be shredded to dust. Our Sun will have the same fate in some billions years. After the explosion, it’s like the blast gets frozen in the space and forms clouds of dust and gases. What you see now is a result of such a violent incident, a Nebula. Nebula has a new purpose, it acts like a nursery to new stars. Much less powerful and bright but the stars grow in course of time. The small dim twinklings that we saw are the new born baby stars. They are formed of the leftover dust particles of the exploded stars, from the ashes of the dead rises a new born star.

Such Explosions can also cause black hole to occur in the fabric of space. It is said if a high amount of energy can be concentrated to a particular place in space it can punch a hole in the area of space probably open a new portal to other distant galaxies or universe. As we all know that scientists have theorized space as a piece of cloth thus just like cloths have very small microscopic holes in it, too small to see with naked eyes. The space also has them, all we need to do is concentrate on a particular place in space with extremely high amount of energy. This will as a result expand the hole making it much bigger to pass through it. This is called the wormhole. Wormholes are much weaker and might close on its own after a brief period. To strengthen that portal and keep it open for a much longer time we need anti-matter, something our scientist are in search for. Anti-matters are released during the explosions of stars, to be little specific when two hydrogen or helium atoms collide it releases anti-matter. In CERN, Switzerland  such anti-matters are produced in the Large Hadron Collider during experiments but the amount is too small. We need a huge and unlimited supply of anti-matter to actually fulfill our dreams of Interstellar travel, Time Wraps, Wormholes. All comes in the reach of mankind once we get a way of producing Anti-matters at a larger scale.

By now you must be thinking what is antimatter? Well not to blow your mind with quantum physics, but in a very simple way let me try to explain you. Antimatter is made of antiparticle and has the same mass as of matter but opposite charge. Previously antimatter was thought to be anything that possesses negative gravity. It was even thought that we live in a place which is comprised of matter and then there are place, even solar systems which are comprised of antimatter. In short such a universe comprising of antimatter will have everything opposite to our environment. The negative will be positive and vice versa. Later in modern physics it was found out that this theory is more of speculation and ideas and in reality antimatter are comprised of antiparticle having anti atoms with anti electrons. Just as we know atom comprises of a proton (being positive charge), neutron (neutral) and electrons (negative charge). The anti atoms consist of just the opposite, to differentiate mainly anti protons and anti electrons also known as positrons, electrons with positive charge. This is something that we don’t find in the elements of our periodic table. In a matter the atoms have electron which are always negative in charge but in antimatter particle its positive. Doesn’t this gives us a feel of a different universe, something that man will not ever find in his world. Antimatter are not difficult to find, using Gamma ray telescope we can spot clusters of antimatter all over the universe, although it’s out of the reach of our hands.
