Dark Matter

Image
What is dark matter? What is Black matter? What is the dark matter theory all about? Is there anything out there in the universe which causes all these asteroid and volcanic attacks on earth? Is there another universe made out of something that we can never even feel? Get all these answers in this article about dark matter. This is what dark matter is presumed to look like: If you are a space fanatic like me, then you probably would know that the sun revolves around the center of the milky way galaxy, and has a pendulum-like up and down motion during it's path(this up and down pendulum like motion is represented by the green lines in the figure below.) Then, you will also know that disasters like huge volcanic eruptions and meteor attacks have led to the complete wipe-out of many species, one of them being dinosaurs. So, what's the pattern of all this? Is there any time interval between them? Is it going to happen to us humans also? Answer: I don't know...

Neutron Star

What is a neutron star? What does it look like? What are the mind-blowing activities that happen near it and in it? How is it formed? In my last blog, I wrote about Supernova, the end product of which is a 'neutron star', and that's what I'm going to talk about now. So.. Which is the densest thing? answer: Osmium, density:  more than 100 grams in a teaspoonful. But that's only on earth. The universe is of another level.. The densest thing in the universe is the neutron star.                       That's what it looks like. What do we know about the regular matter on earth? - It is made up of atoms with electrons revolving around neutrons and protons. But it's completely different with a neutron star. The lines you see near the neutron star in the figure above are the strong magnetic field lines, enough to pull out the iron in the haemoglobin inside your blood. As I have discussed in my ...

The Supernova

Image
What comes to your mind when you think of the universe? probably a huge number of stars in a black background..probably the sun shining on some planets.. Just after supernova, this is seen. But the universe is a lot more than that. The universe is very, very and very energetic and active. There is a supernova happening right now even when you are reading this article, though millions and millions of light years away! Yes, I am now going to talk about this super energetic phenomenon - A Supernova. A Supernova looks something like this: So you surely do know about gravity, right? Gravity plays a huge role in a supernova. So these hydrogen, helium, etc. all types of molecules and gases are present in a star. The gravity of a star is intense, owing to it's huge mass. This gravity pulls these atoms and molecules close together at the nucleus of the star, and intense pressure is developed there at the center. This continues to build up over a long period of t...
