Mr What Astronomy

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...

One fine day, I asked my friend about the largest moon of Jupiter checking whether he could answer the question. Surprisingly, he didn’t know (which by the way is Ganymede). I asked him about the boundary of our solar system, but he couldn’t answer that question too. So today you guys are going to read a blog on Our Solar System. Most of the people in our world know that there are 8 planets, 1 star and a few miscellaneous space debris in our solar system. Well that is right but that is not all of our solar system. So let’s discuss everything about our solar system step by step. 1.        Sun – Our parent star in our solar system’s name is the Sun. It is 1.39 million km in diameter.   About 1.3 million earths could fit in the sun. It is approximately 5 billion years old. It is 333,000 times heavier than the Earth. The surface temperature of the sun is 6000 o C. The sun is powered by a process called nuclear fusion. When the sun was born, it was ...

Wormholes, what are they? When you hear such a word, you see a worm creating a hole in an apple. Well today’s blog is different. Wormholes are hypothetical portals linking two points in space time. Won’t it be so exciting to see one and go through one? Yes, it would. Lets explore them. Currently they only exist on paper. But for the future, we have white listed three types. In the end I will also explain about a wormhole designed by me. The three types are – 1.        Einstein – Rosen bridges – Einstein Rosen Bridges are basically portals. It is believed that these types of wormholes were basically black holes opening into white holes . Oh sorry, we have not discussed white holes. A white hole is another powerful object in our universe which does the opposite of a black hole. Instead of eating stuff, it spews energy. Now back to topic, these wormholes open into another planet, Galaxy or even a Universe. Now that is a flaw. Trying to go through one woul...

In the previous articles we have discussed about, interstellar travel, Dyson spheres and the Kardashev scale. Have you ever imagined what black holes are? Black Holes are basically super gravity vortexes formed after the death of a big star at least 8 times the mass of the Sun. Black holes are the most powerful objects in the whole universe. They have a ground breaking gravity of the speed of light. They can devour literally anything. A black hole is made up of 2 parts. The event horizon and the singularity. The event horizon is the part of the black hole which devours everything. The singularity is where all the devoured material goes to. The black hole has an interesting gravity. The gravity it applies on the side of the object facing it is a million times the gravity applied on the opposite side. The largest black hole in the universe is TON – 618. It has a diameter of 390 Billion Kilometres which is 1/3 rd of a light year. Black holes are so strong that they don’t even let light e...

                                                                                Stellar Engines Imagine you are a 16 year old interning to be an astronomer in NASA. One fine night you notice something strange. You see a tiny red spot in the sky while stargazing using your Celestron 660 Power Vision telescope. You know how red stars look like, but this looks different. It looks very suspicious and you believe that aliens have finally arrived. You submit the picture to the NASA Astronomy Department. They immediately use the small but efficient telescopes in their department. It looks very strange and they are unable to identify it. They immediately alert the Mauna Kea Observatories in Hawaii. The observatories are able to pin point the location for th...

  How to Start an Inter-Universal Civilization Part – 2 Last article we discussed that you are a man who has been granted immortal life until we establish full control over the multi-verse. We must also reach stage 5 on the Kardashev Scale. Since this is a huge task, James has been given immortality. The solar mission is still going on and we are collecting every scrap of resource to make the Dyson Sphere. From Mercury we found a very strong metal and named it Kalnet. Kalnet is super strong and durable. But Kalnet is very rare so we won't be able to do a lot with it. Now we must choose another alternative. We have strip-mined Venus, Mercury, Mars and the Moon, this won't cut it. Since there are no more rocky planets left in the Solar system, we can start mining asteroids. Asteroids are small celestial bodies(not very small) which are usually found in the Asteroid Belt and the Kuiper Belt. I once saw a Kurzgesagt video about mining asteroids.  An idea to mine asteroids is t...

How to Start an Inter-Universal Civilization Part 1  Our dream has always been to annex space like in the sci-fi shows. They are always bouncing around in their spaceships and colonizing planets. If we want to become like them, we need fuel or energy which we can get from the Dyson Sphere which we discussed in the previous articles. Once we have this sorted, we can safely try to go beyond our solar system. Won’t that be exciting? Let us start our journey.  Imagine you are a character, say James Peter. You have received the boon of being immortal and have the power to see all of the stages of our universe until it dies. You start on Present day earth where everything is fine and dandy. America is fighting with other countries for oil, Covid 19 is slowly being killed as the vaccine has been made, India is still defending itself from the rest of the subcontinent etc etc etc. Few Months later the solar mission has started. Every country is contributing money as well as its space ...
