How Big is the Biggest and How Small is the Smallest

We always use superlatives during our talk such as

Largest Airport                 – (King Khalid International Airport, Saudi Arabia)

Highest Airport                – (Lhasa Air­port, Tibet)

Tallest Animal                  – (Giraffe)

Largest Animal                – (Blue Bottom whale)

Smallest Country             – (Vatican City)

Highest Mountain Peak     - (Mount Everest, Nepal) etc.

But, what is the biggest of the biggest and smallest of the smallest?

Let us think it in terms of the three basic physical entities such as Mass, Length and Time; Just a wild estimation.

MASS

How small you can imagine/feel in your mind without any equipment may be 0.0004 Kg, what is the highest; may be 1000 Kg.  

In reality what is the smallest mass in the universe? Physics says it is the mass of an electron ie. 10^ -30 Kg

What could be the highest mass? No doubt it should be the mass of our universe itself. Surely there is no weigh bridge available to measure this mass; hence we use a wild estimation. We take our sun as a representative measure. It is estimated that the sun has a mass of 10^30 Kg. It is also estimated that there are at least 10^11 suns in a galaxy and there are not less than 10^11 Galaxies in the universe, thus 10^11 galaxies  x  10^11 stars  x   10^30 Kg.       = 10^52 Kg

Smallest mass (Mass of an electron)            =       10^ -30 KG

Largest Mass (Mass of the Universe)            =       10^52 Kg. 

 

LENGTH

The smallest is the plank length, which is equal to 1.6 x  10^ -35 meter.
It is a measure used in quantum mechanics. General relativity and quantum field theory would be needed to understand the behavior of an object whose radius is about the Planck length. It is derived from the fundamental physical constants like gravitational constant (G), speed of light(C) and Plank’s constant (h).

The largest length that we can imagined is the diameter of the universe which is estimated as 10^26 meters

TIME

The smallest time is again Plank time ie. 10^ -42 seconds and the biggest time, no doubt is the age of the universe 10^ 17 seconds.

Table of compilation

Item	Smallest	Biggest
Mass (Kg.)	10^ -30	10^ 52
Length (Meter)	10^ -35	10^26
Time (Seconds)	10^ -42	10^ 17

And finally, what was the size of our universe before the BIG BANG?

10^ -35 meter at 10^ -42 seconds and it expanded 10^ 30 times in 10^ -34 seconds.

Suppose a coin of 1cm in diameter suddenly blew up to 10 million times of the width of our milky way.

Science fiction? No real science; exotic.  Yeh ?
