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??
