JOURNEY TOWARDS SPACE EXPLORATION

    How the sun is born? Where does it get its light from? Well, imagine it’s a Sunday morning and you woke up just before your alarm. And suddenly you see no sunlight our there! Eventually, you realized that the sun of your solar system is dead.  How different your life would be now? How do ecosystems would react? but First of all, would you be able to survive? Ok ok, stop imagining! I know this would be a nightmare to face on a Sunday morning. But before that let’s dive back to the question, how is our sun born? If you read my previous blog, you are very well aware of the big bang. Here, just after few seconds of the big bang, the stars or sun begin to form (make sure that stars and sun are the same). Now to make the sun here are some ingredients we need! Ingredients:               1. Some Gases               2. Gravity               3. Time. In the initial stage of the formation of the universe, there was nothing but gases and a vacuum all over the empty space. These gases start to

  The telescope that will work as a time machine! When we say telescope everyone has this only picture in the mind – But telescopes are not only used on the earth, but in space too. In fact, we get a more clear and effective view of space when it’s taken from a space telescope than any telescope on the earth. This is one of the telescopes situated on the earth's surface. On the earth, we have a dense atmosphere with various components and gases as well as polluted air which blocks the view of outer space. The other problem is light pollution.  Due to large cities and urban areas we have lots of bright light in the sky which makes celestial objects blur. So we didn’t get clear and exact images of the celestial object as it is. So, to solve this problem, many decades ago humans launched space telescopes that are orbiting the earth, outside its atmosphere. When we don’t have any light and air pollution we can easily get pictures of the stars and galaxies.                              

  What would happen to your body when exposed into  the space???      You decided to take walk outside your spaceship and went without your spacesuit, imagine what would consequently happen to you? Option A: your blood will boil? Option B: your body would burst into pieces? Option 3: you will freeze into ice? Option 4:you would get burnt? Okay! Did you lock your answer? Let's dive into the scientific reasons behind this. First thing you are not surrounded by oxygen anymore. And hence your lungs will run out of air storage. In this case, if you tried to hold your breath just like we do in water, your lungs will explode due to the absence of outside atmospheric, just like a balloon. So letting your breath out would be a good idea to survive for a few more minutes. Your brain will turn off in 10 to 15 seconds due to lack of oxygen and will make you unconscious. Now you have only 30 seconds to 2minutes to wake up again if you get an external oxygen supply between this ti

  WHAT IF YOU TIME TRAVELLED IN THE PAST AND KILLED YOUR GRANDFATHER? SUPPOSE you created a time machine, and you decided to go in the past and apparently kill your grandfather!  Terrifying isn’t it?  What would exactly happen to you then? This is termed GRANDFATHER PARADOX. Now to solve this paradox, I referred the articles of various mathematicians and physicists, by putting them all together in a simple language here I present my next blog related to time. First of all, time travel would never allow the possibility of self-annihilation. (making your existence disappear from the past, present, and future) . then what would happen if you do so? BRANCHING TIME TRAVEL: according to the philosophers  Nuel Belnap and David Deutsch , when you travel back in time you don’t actually travel in your original timeline, but in an alternate timeline of the alternate universe just like yours. And when you point a gun towards your grandfather and shot it, you are killing your identical grandfather

  WHAT IS TIME? FOR US TIME PLAYS AN IMPORTANT ROLE IN OUR DAILY LIVES. BUT DOES TIME EVEN EXIST? MANY SCIENTIST HAVE DEBATED OVER THIS TOPIC BY GIVING MANY THEORIES. THEORY OF RELATIVITY AND QUANTUM MACHANICS ARE BOTH AGAINST EACH OTHER WHICH HAVE THEIR INDIVIDUAL OPINION. TIME CAN BE THE FORTH DIMENSION. AS WE LIVE IN A 3D WORLD TIME IS USED TO PLOT OUR 3D EVENTS IN AN SPECIFIC ORDER. ON THE OTHER HAND I TOO BELIEVE THAT "TIME IS AN ILLUSION" . WE ARE NOT IN THE TICKING WORLD. IN FACT ITS OPPOSITE, JUST LIKE WATER IN THE UNIVERSE IS HAPPENING. IT ISN'T AN EVENT. IT IS A CONSTANT EVENT OR IN THE OTHER WORDS ITS EVENTING. WE ARE SIMPLY HAPPENING. TIME IS REAL WHEN WE CREATE IT IN OUR CONCIOUSNESS. OFCOURSE TIME GET SLOWER NEAR HEAVIER OBJECTS, AND FAST IN VACCUM. BUT STILL THE QUESTION REMAINS, WHAT IS EXACTLY TIME... IS IT JUST AN HYPOTHETICAL THINKING OF HUMANS? COMMENT DOWN YOUR OPINIONS IT WOULD GREAT TO LISTEN ABOUT IT FROM YOU.
