DISTANCE(DIAMETER) OF THE OBSERVABLE UNIVERSE:

                       

Light speed per second= 3,00,000 km.
Light speed per minute= 18,000,000 km.
Light speed per hour=1,080,000,000 km.
Light speed per day=25,920,000,000 km
one light year= 9,460,800,000,000 km
one Billion light years= 9,460,800,000,000,000,000,000 km
93 Billion light years= 879,854,400,000,000,000,000,000 km

It means distance(diameter) of the observable universe is 879 sextillion 854 Quintillion 400 Quadrillion Kilometres.

In other words, if we assume an average person to be 1.5 meters tall, then if all of them sleep Horizontally on a straight line, the people that take to cover the entire observable universe without any obstacles are equal to 586,862,884,800,000,000,000,000,000 persons
which means 586 septillion 862 sextillion 884 quintillion 800 Quadrillion average heighted Homosapiens, then we everybody can travel through the observable universe.

NUMBERS GAME...isn't it??

Do you know?

Why the detection of gravitational waves are very important?
     
                            let me tell you all an analogy including the mathematical facts.

• Our sun produces 100,000,000,000 or 100 billion hydrogen bombs per second. It's estimated age is 10 billion years. So total hydrogen bombs produced by our sun in its life time is 100,000,000,000*60*60*24*365*10,000,000,000=31,536,000,000,000,000,000,000,000,000 hydrogen bombs or 31 nanallion 536 septillion hydrogen bombs. This is only one tenth of its total energy. Rest of it is in super novae and white dwarf.
• But in that event of collision of black holes detected by LIGO,  three solar masses disappeared into gravitational waves in 2/10th of a second.
• Therefore, total energy produced by that collision of a black holes is 946,080,000,000,000,000,000,000,000,000 hydrogen bombs or 946 nanallion 080 septillion hydrogen bombs in 2/10th of a second.
• Now the no of solar massed stars energy required to match this is (946,080,000,000,000,000,000,000,000,000/100,000,000,000)*10/2= 47,304,000,000,000,000,000 stars or 47 quintillion 304 quadrillion stars energy produced in 2/10th of a second. Which is more than the entire energy produced by all the stars in the observable universe at that moment. 
• And the detection of that massive energy amounts to 1/1000th of the diameter of the nucleus of a proton. The gravitational wave is traveling near light speed from 1.3 billion years and when these two black holes are colliding, there are only single celled organisms in the earth.

                                   100 years ago Albert Einstein predicted these gravitational waves, and on September 14th 2015, these waves are detected by LIGO in two detectors.

                      Seems exciting??
