Sphericity of Earth:

The Sun does never set nor rise. When people think the Sun is setting it is not so. For after having arrived at the end of the day it makes itself produce two opposite effects, making night to what is below and day to what is on the other sideHaving reached the end of the night, it makes itself produce two opposite effects, making day to what is below and night to what is on the other side. In fact, the Sun never sets.

Shape of Earth is like an Oblate Spheroid

Earth is flattened at the poles

Polar Days and Nights

For the period when the sun is north it is visible for six months at the north pole and invisible at the south, and vice versa.

June 21, 1999: Later today, at 19:49 UT (3:49 p.m. EDT), Earth's north pole points more directly at the Sun than at any other time during the year. For polar bears and other denizens of the Arctic it will be noontime, the middle of a 6-month long day, as the Sun climbs to 23 1/2 degrees above the horizon.

June 21st marks the beginning of summer in the Northern Hemisphere and the beginning of winter in the Southern Hemisphere. In the North it's the longest day of the year. At mid-latitudes there is sunlight for over 16 hours. Above the Arctic Circle the sun doesn't set at all!

"He made this Earth fixed by different devices like hills and mountains in shape of pegs but it still rotates . Sun never sets; all parts of earth are not in Darkness."

Now lets see what Hindu scriptures say about the movement of earth:

"Earth rotates in two ways by the Will of Brahama, first it rotates on its axis secondly it revolves around sun. Days and Nights are distinguished when moves on its axis. Season change when it revolves around Sun".

"There are suns in all directions, the night sky being full of them."

In the 1920s astronomers realised that our island universe, the Milky Way Galaxy, is not alone in space. Outside it are other galaxies, each containing thousands of millions of suns. One of these other galaxies is visible to the naked eye, as a faint fuzzy blob in the constellation of Andromeda. The Andromeda galaxy is similar in size and shape to the Milky Way and is our galaxy's nearest neighbour, 2 million light years (20000000000000000000000 km) away. Further away are other galaxies, too faint for the eye to see. With powerful telescopes, millions have been photographed. Remarkably, all the galaxies are fleeing from one another: the whole Universe is expanding. This is one of the key pieces of evidence that about 15000 million years ago, there was a beginning to the Universe, an immense explosion we call the Big Bang. The debris from the explosion is still flying apart. Earth is one of the cinders.

There are planets in all directions, but only visible in night sky

Now lets see what Modern Science says:

A galaxy is a giant assembly of many stars. We live on a planet which is in a group of 9 planets orbiting a star in one such assembly, a spiral galaxy we call the Milky Way (from the old Latin name Via Lactea). There are an estimated 50-100 billion galaxies in the Universe. Each galaxy has millions or billions of stars like our Sun, or bigger, smaller, newer, older, colder, hotter, exploding or imploding. It comprise of Millions of Planets like ours, or bigger, smaller, newer, older or hotter.

Recently, astronomers have detected planets circling stars in our galaxy. Hard evidence (not just probability) is every day accruing that many other stars in the Universe have planets around them.

Hinduism is the only religion in which the time scales correspond, to those of modern scientific cosmology. The Hindu literature is work of a Genius.

It looks like that the writers of Vedas and Puran came from the future to deliver knowledge. The works of the Ancient Arya Sages is mind blowing. There is no doubt that Purans and Vedas are word of God.

How could Hindus (Aryas) have possibly known all this 6,000 years ago, when scientists have only recently discovered this using advanced equipment which did not exist at that time? Such concepts were found only recently.

Blue Sky is Nothing but scattered sunlight

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue

As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white
