# Universe Size 13.7 Billion Light Years Surya Siddhanta Science Agrees

When one talks of Distances in Space one is struck by the sheer magnitude of it.

The distances involved are so huge that the Speed of Light is taken as the base.

Even this is not sufficient to comprehend and measure large numbers involved.

Hence the concept of AU, Astronomical Unit.

One AU equals the distance traveled by Light in a Year.

That is 149 597 871 Kilometers.

Definition: An Astronomical Unit is the mean distance between the Earth and the Sun. In 2012, the International Astronomical Union defined the distance to be 149,597,870,700 meters.(http://neo.jpl.nasa.gov/glossary/au.html)

Astronomers have measured the age of the universe to be approximately 13.8 billion years old. Because of the connection between distance and thespeed of light, this means they can look at a region of space that lies 13.8 billion light-years away. Like a ship in the empty ocean, astronomers on Earth can turn their telescopes to peer 13.8 billion light-years in every direction, which puts *Earth inside of an observable sphere with a radius of 13.8 billion light-years. The word “observable” is key; the sphere limits what scientists can see but not what is there.

But though the sphere appears almost 28 billion light-years in diameter, it is far larger. Scientists know that the universe is expanding. Thus, while scientists might see a spot that lay 13.8 billion light-years from Earth at the time of the Big Bang, the universe has continued to expand over its lifetime. Today, that same spot is 46 billion light-years away, making the diameter of the observable universe a sphere around 92 billion light-years

What Surya Siddhnata Siddhantha says.

Saurapakshiya Suryasiddhanta speaks of a mahayuga of 4320000 years, so do the Puranas.

There are 14 universes (Bhuvanas) according to Vedic-Puranic tradition, and our material (physical) Universe is at the middle level. We can see 7 universes at a time in any one direction, but not all 14 simultaneously. *According to Suryasiddhanta 1955885109 years have elapsed (in 2009 AD) since the beginning of Creation. When we see seven universes arranged one after another, we see into (1955885109 * 7 =) 13691 million years of TIME, and into 13691 million light-years of SPACE. Currently, scientists believe the extent of Universe to be of 13.7 billion light years.

Divide 13.7 billion years with 10^42 (10 raised to the power 42, or 42 zeroes after 1).

13.7 billion years = (13,691,195,763 years) * (31558149.61 seconds per year) = 4.320688 * {10^17} seconds

This is the largest QUANTUM of TIME.”

Modern Astronomy confirms this.

* One has to know that Speed and distance are interchangeable while talking of large distance numbers in Space.
