Mr What Astronomy

 When I was small, I was often asked the question – What is the smallest thing on earth? As I grew, my answers changed. They changed from molecules to atoms to neutron to electrons. Now in the recent months of my interest in particle physics, I have come quite a far way. I now have a greater understanding of our universe’s building blocks. Most of you might know that an electron is the smallest thing in the Universe. That is right and you have the answer right. Except, there are more particles having similar sizes compared to the electron. So today we are going to discuss the Standard Model of Particle Physics or just the Standard Model. The Standard Model is a table of 17 objects which have created the Universe. Without these objects we won’t exist or the Universe. The Standard Model is divided into 2 categories "Fermions" and  " Bosons" I know, that you may sound confused reading this and you are absolutely fine to get confused. 1.   Fermions:  Fermions ...

The Multiverse We always think of our Universe as giant, humongous and huge. It really is, but like a Solar system is home to a planet, a Galaxy is home to many Solar systems, a Super-cluster is home to many Galaxies and the Universe is home to a Super-clusters. But have you ever imagined what is home to the Universe? Well, in today’s article we are going to discuss about the Multiverse which is home to the Universes. Let’s start with the smallest things in the Universe to the largest. As some of my readers may know that the smallest object in the universe is an Electron (there are even smaller objects but we won’t discuss them now). Now from here let’s start the size comparison - Electron < Atoms < Molecules <Solids/Liquids/Gases < Comet < Meteor < Asteroid < Dwarf Moon < Dwarf Planet < Moon < Neutron Star < Planet < Dwarf Stars < Mega-Planet < Star < Stellar Mass Black hole < Solar system < Super-massive Black Hole < Galaxy ...

My father’s friend after reading my Black Holes blog suggested that I should write my blog on the Bo ö tes Void. So, fellow readers, my next blog will be a combination of two blogs. So what is the Bo ö tes Void?  And why does it sound so mysterious? The Bo ö tes Void is literally a void. A void is basically empty space and nothing else. Unlike normal voids, the Bo ö tes Void has a few galaxies. The Bo ö tes Void is considered the largest void or empty space in the Universe. It has a diameter of 330 Million light-years. Just for reference, the Milky Way only has a diameter of 100,000 light-years. The Bo ö tes Void is 700 Million light-years far from the Earth. The Bo ö tes Void was discovered by a Harvard Professor Robert Kirshner in 1981. This discovery brought terror to astronomers across the world. The Bo ö tes void is literally the largest object in the universe. Just close your eyes and imagine you can move at the speed of light. If you are at the edge of the Boötes void, it ...

The distance between the Sun and Earth is 150 Million km. When you are trying to tell this to somebody, it gets quite tiring just saying 150 Million km. So the scientists have shortened this distance to 1 AU(Astronomical Unit). Now in today’s blog, we are going to discuss a lot of terms or words related to our Universe. 1.        Star – Stars are large masses of hot boiling plasma. They are mainly composed of Hydrogen and Helium. They are formed from the dust clouds of dead stars or planets. Stars are of many types – 1.        Neutron Star – Neutron stars are the smallest type of stars. They are formed from the remains of a giant star. Neutron stars have one of the strongest gravities in the universe. They are the size of a city (approx. 20km). 2.        Red Dwarfs – Red Dwarfs are the most common type of stars in the universe. They are small and quite cool. Red Dwarfs are also the stars t...
