THE TURTLE CO

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 ...

 We know that everything around us is made up of elements and compounds. Our entire universe constitutes of chemical elements and compounds. We situated all these elements in a periodic table. So many elements were found. But scientists are still trying to find new elements every day. In the periodic table, every element represents a particular type of matter, and these have different properties but there isn't an element that represents the properties of gravity. We are experiencing gravity just as a force but we haven't found an element representing it. If we found one, then it would be called Graviton, then this graviton can be the Theory of Everything. Quantum Mechanics deals with properties like matter, light, and energy at atomic and subatomic levels. In general, it is the probability of a particle to move from point A to point B. It deals in the scale of atomic and subatomic levels instead the string theory goes deep inside. Atom is the basic constituent of matter, but i...
