BIG UNIVERSE... small humans

                     

Looking into the night sky, the exact number of stars are unimaginable. We

see them as tiny dots of light because they are so far away. But how far

away are they? 1,000,000,000 kilometers...a trillion? We will soon find

out. Also we will discover just how big they are and how small we are in the

vast universe.

The earth is our home, how beautiful and conducive it is. It is

massive but when compared to some stars, it may as well be just a tiny dot. Also

when we compare the sun to some stars, it is like a tennis ball.

Our solar system houses our planet with the sun as its star. But how

large is the sun compared to the earth? If the sun was to be reduced to

the size of a large volleyball, the earth would be as small as a grain

of beans and Jupiter would be like a medium-sized orange fruit. Now

our solar system is in the Orion arm of our galaxy with billions of

stars and the closest star is about 4 light years away (distance

travelled by light in 4 years) 1 light year equals 9.64×1012 km.

that means the closest star to us apart from the sun is about 3.853×

1013 km and the name of this star is Proxima Centauri. On earth's

scale, if the sun is a small grain, the nearest star would be 4km

away. Now that's far. But our galaxy, which is called the Milky Way, is

about 100,000 light years in diameter. That's 9.64×1017 km. On

earth's scale, if the sun was a cell, the galaxy would be as large as

America.

Now our galaxy is only one in many billions of other galaxies with the

Andromeda galaxy as our closest neighbor at about 2.5 million

light years away. That's about 2.41×1019 kilometers. That's so far

and, mind you, light moves at a speed of 300,000 km every second. That's

like cycling the earth 7 times in a sec.

Our universe is about 93 billion light years in distance, taking earth as the

center. Now that's about 8.9652×1021 kilometers

(8965200000000000000000 km). Now that's long. Having known that, when

you compare the sun to the universe, it's like comparing an atom to the

earth.

The sun as we know it is just an average sized star. The biggest star

in our galaxy (Canis Majoris) is thousands of times large than the

sun, and the largest star in our universe UY Scuti is so large that

when compared to the Sun, it's like a tennis ball compared to a 16

story building.

And modern studies are showing that our universe might just be a

bubble in an infinity number of other universes (multiverse). Where does

that leave humans?

But I have confidence when Brian Cox said "We are the universe made conscious.”
