Standard Distance Between Sofa and TV

Typical TV distance from seating couch

How calculate the distance between the TV and the sofa?

Typically followed seating distance for the best picture on a TV is 1.5 to 2.5 times the TV size.

The best and most comfortable distance measurement is- 

2.75 x Screen Size of your TV: Place your sofa at a distance of 2.75 inches away for each inch of diagonal screen size. 

This formula puts your sofa at 110 inches from your TV, if the TV is 40 inches sized.

Recommended distance for TV and seating couch

How much space do you need between the couch and the TV, you can estimate from the following list for 1080p HD TV and 4K ULTRA HD TV sizes.

The Earth Created by What?

Fig: Small man on Big Desert.

The earth created elements but oxygen was the most important in the development of life.

The earth was created by the forces of nature. The elements were created by the sun and the moon, who created them from their own substance. The earth has been around for millions of years and is now covered in life.

In this book, we will explore what causes elements to form and how they come into existence. We will take a look at some of the other important elements that make up our world.

We will also explore how history has affected the creation of these elements and how they are used today in our lives.

Why The Sun Become Reddish During Sunset?

Sunset at sea-shore, you will find the sun as like a reddish dining plate, the moment is very lovely, we must like it. During this time the sun looks very red, but the sun color is never red.

During the day time you cannot find the sun in this color, only a particular moment of the day you will find it like this reddish color. 

The fact is that when you find the sun is red during sunset, at the same time others people from thousand kilo meters away from you cannot see it red. So, the sun never be red.

The sun become reddish during sunset because the distance from us that the sunlight passes through the space. You can remember that the sunlight actually contains all the colors. Our eyes detect the sunlight as white that actually a mixture of all colors.

But in the space around us where presence the air, dust, humidity or water particles, and many more micro particles that light refraction property is different.

During sunset at the horizon, due to the light refraction property in different particles, we see the red and yellow color more than the others color that makes the sun reddish to us.

For the same reason, we see the sky blue during the clear weather. 

Why Does The Sun Give Us Light?

 It is difficult to believe that what we see at night in the sky and the bright sun at day time is the same things. It is true that the sun is also a star that is the closet star of the earth. 

What we mean by life that totally depends on the sun. If the light and heat do not come to the earth from the sun, it was impossible to create and exist life on the earth. Without sunlight the green trees and human cannot exist. 

The sun is 93,000,000 miles away from the earth and 1,300,000 times bigger than the earth.

It is very interesting that the sun not solid as like as the earth. The temperature of the sun surface is 6,000^oC. This super high temperature is enough to be any material into gas. So, no doubt the sun is in gaseous state. 

Earlier, the scientists were believe that the sun is burning continuously to generate the light and heat. Recently the scientists are changed their mind and believe that the sun generate light and heat as like the atomic bomb working principle. 

Actually the light and the heat generate on the sun converting the particle of matter into energy that is completely different from burning.

In burning procedure matter changes the state from one form to other, but in converting particle to energy its required very small amount of matter to produce huge amount of energy.

Example:

Only 28g particle can produce such amount of energy that can melt more than 1,000,000 tons stone.

So, if the science is true, the sun is converting materials in energy continuously to produce light and heat.

When the sun will become useless or become zero mass? The sun can generate heat and light energy for 150 thousand million (150,000,000,000) years just using 1% of its mass.
