The Vast Space and Possibilities of Life

With one hundred billion galaxies hovered around and above our galaxy and with trillions of planets floating within our own galaxy, researchers suggest there could be possibilities of adapted living beings on planets we have yet to discover.


Researchers state that our universe is so big that even light hasn’t had time to cross it in nearly 14 billion years.  The speed of light is so intense it travels 186, 282 miles per second. That means the time it took you to read this far, a proton leaving the sun has traveled about 10 million kilometers which is the same as travelling around the earth 250 times. The universe is filled with endless amounts of galaxies and the closest large galaxy to us is Andromeda, which can be seen from our own planet in the night with the naked eye.

Out of all the planets, Is our planet really the only planet in the entire universe that is thriving with life? Scientists say that our own solar system contains 100 billion planets and there are approximately 2 trillion galaxies in the entire universe. Now think how many planets there might be in one of every 2 trillion galaxies in the whole universe. Out of all these, is earth the only planet that exists with life? To me, that seems impossible.


There are organisms which are scientifically known as (Extremophiles) which thrive within harsh conditions. They live where no other organism can or should ever exist. 4 examples of such adapted organisms are:


1. Water Bears. 

This unbelievable microscopic organism survives in temperatures of (-273°C) and high temperatures reaching more than (150°C).


2. Wood Frogs.

Wood frogs survive months completely frozen into ice. Surviving in temperatures below (-14.6°) including as low as (-18°C)


3. Himalayan Jumping spiders.

The Himalayan Spider is found living on Mount Everest with very low oxygen levels at elevations as high as 22,000 feet. They rely on dead insects blown up by the wind as their of food.


4. Kangaroo Rats.

Kangaroo Rats can survive without ever having to drink water, whilst in the heat of the desert. They obtain water from the metabolic oxidation of seeds they eat.


In conclusion, we may never know if there are any planets with life. However, that does not mean that there are no possibilities of life within them. Our earth itself is very small when compared to immerse scale of the entire universe and still, even our own ocean is yet to be discovered. Read my previous post to learn about the Mariana trench and how its fishes swim within the depth and pressure of it with no problem what so ever.
