HOW BIG IS THE UNIVERSE?

UNDERSTANDING UNIVERSE IN A NUTSHELL  Our universe is estimated to be around  93 billion light-years width and  it's constantly expanding but then again  that's just the observable universe  alone  astronomy is an amazing field of science  but before you dive into the wonderful  world of astronomy let me share with you  some basic facts that might help you, later on,  let's start off with the term  Lightyear which is a very commonly used  astronomical term but what exactly does  it mean a Lightyear simply put is a  distance light travels in one year which  is about  5.88  trillion  miles. In astronomy, we also use the  word parsec which means 3.26  light-years but let's just try to  keep things as simple as possible so we  now know that one light-year is about 5.88  miles  and the universe is about 93 billion  light-years wide and when we multiply  those two ...

TIME DILATION

TO THE FUTURE Have you ever thought of time traveling? Trying to know about your future? What will happen next? How would you look when you become old? I'm pretty sure you have. And you also might have thought that it would be practically impossible. But there was a man who once traveled through time. He is Sergei Krikalev, was a Russian astronaut, has a record of 803.371 days spent in space. He actually traveled through time to his future by 0.02 seconds. Here, what he experienced is not time traveling but time dilation.                                        TIME DILATION There are many ways to explain time dilation. It can be said as the difference between the time in two clocks, each having their individual velocity or the difference between Gravitational potential between their locations. To be put in simple words, time dilation is the process of slowing down the clocks bec...
