As we all know, sand is the main foundation of all forms of life, and comparing Earth as the size of sand grains is illogical.
If the Earth was the size of a grain of sand, the sun would be about the size of a pool ball (5.5cm or 2.17 in). Our own Milky Way galaxy which is home to hundreds of billions of stars is estimated to be about 125,000 light-years in diameter.
If Earth was the size of a grain of sand, the Milky Way would still be unimaginably huge.
To help conceptualize these even larger structures in our universe we are going to need to go smaller. Let’s now imagine that our entire solar system is shrunk down to the size of a grain of sand. Now we can start to picture how big the galaxy is and how close we are to other galaxies.
Earth as a grain of sand…..
Suppose the earth is a slightly larger piece of sand, about 1.27 mm in diameter. So scale the universe to the size of a grain of sand, walk to Pluto in 10 minutes, planets fly like airplanes, there are galaxies in the solar system, but the edge of the universe is only as far as the nearest star. It’s so big.
Assuming the earth is a slightly larger grain of sand, about 1.27 mm in diameter. The range of values given is 10 to the 10th power or 10 billion to 1.
Measuring the size of the entire universe is next to impossible because it is bigger than the biggest thing you ever imagined.
Is Calculation Of The Size Of Universe Is Possible??
The universe is the unity of all time, space, and its contents; it contains planets, stars, galaxies, subatomic particles, and all matter and energy. The size of the entire universe may be infinite, but it is not conclusive. According to American astronomer, Carl Sagan who once stated that “There are more stars in our universe than there are grains of sand on all the beaches on earth. The question left people surprised at how big the universe is considering that the sand along the earth’s coastlines amounts to trillions of tones.
Conclusion
There is no definite way to determine the exact number of stars in the universe and the number of sand grains along the shores but mathematical estimations can be made that the least number of stars is equal to the highest number of sand grains. However, it is likely that there are five to ten times more stars than sand on the beaches. In 2016 researchers, observing images from the Hubble Space Telescope stated that there could be more than 2 trillion galaxies in the observable universe, which is ten times more than the highest number expected. This is in addition to the fact that the entire universe cannot be observed by any telescope on the earth.
