 Temperature is the physical quantity that tells how cold or hot an object is. The units of temperature are Kelvin(K), Fahrenheit(°F), Celsius(°C). The room temperature is 20 to 25°C.   °C + 273.15 = K  (°F − 32) × 5/9 + 273.15 = K  °F = (°C × 9/5) + 32   But have you ever wondered the highest and lowest temperatures if the Universe ??? Temperatures of different bodies or events :-  • The lowest possible temperature is Absolute Zero. [0 Kelvin],[-273.15°C] • The highest possible temperature is Plank's Temperature.  [ 1.416785×10³² Kelvin ]  • The coldest Nebula in the universe his Boomerang Nebula [-272°C], [1 Kelvin] • The lowest temperature recorded in the solar system is in Uranus [-224°C] • The lowest recorded temperature on earth it is in Antarctica. [ -89°C] • The highest recorded temperature on Earth is in Death Valley, California, US. [56.7°C] • The average temperature on Venus [hottest planet] is 464°C / 737 Kelvin  • The temper...

On 28th June 2009, Professor Stephen Hawking organized a party for time travelers. He wanted to prove time travel was practically impossible. He arranged the party at 52° 12' 21” N, 0° 7' 4.7” E coordinates.  The Discovery Channel tried to go to the party. But, there is a twist. They found the party already finished the day before. This is because Stephen Hawking distributed the invitation cards on 29th so that only time travelers can attend the party. If a person who knows time travel is reading this post, please go to the past to party with Stephen Hawking. He is eagerly waiting for you. Thank you. The result was no Time Traveler came. Stephen Hawking concluded that time travel was practically impossible. What do you all think about it. Your opinions in the comments below.  I  think time travel is possible. Just we can't interact with anyone in the past. Or we would change the future. For example :-   You go to the past and you don't let your grandfather mee...

  Prof. Stephen hawking once said, " My goal is simple. It is a complete  understanding of the universe, why it is and why it exists at all..."  He was one of the most influential person in this modern era. Despite of his ALS and paralysis , he proved us even when the body isn't free to explore, but with your mind you can do anything.  Imagination is the key to most of the success you see around you. Even Albert Einstein once said, "Logic will take you from A to B, But imagination will take you everywhere..."  Even the most hard we try to know everything, there is always something we never know existed. Prof. Max Plank was once advised by Munich Physics Professor to not go into physics because almost everything was discovered. Later, he won the Nobel prize for laying the foundations of Quantum physics . He replied that he didn't want to discover new thing only understand the field. By his contribution we now know a very new branch of physics called Quantum...
