Have you heard of Goldilocks’ tale ?
At the beginning of the story, Goldilocks enters a house and sees three bowls of porridge. She tastes the first one and jumps back saying it is too hot. She tastes the second one but it is cold as ice. Finally, she tastes the last one and it is just right. Perfect for the Goldilocks. It is the story of 3 choices, whether it is furniture or food.
Now, imagine that the first bowl represents the sun, the second, t Neptune and the last bowl represents our Earth. The universe is an extremely big place, so you would assume it would be easy for humans to find a new planet to expand to — but,here’s a catch! Humans can only survive on a planet with optimal conditions. Humans require food, water, oxygen, and shelter. Humans also need the planet to have a temperature that keeps surface water in a liquid state
. If the planet is too cold then the water will freeze making it solid, if the planet is too hot then the water will evaporate and turn into a gaseous state, a Goldilocks planet has a temperature that is just right.
What makes a Goldilocks planet different from all the other planets is that these rare planets are not too hot and not too cold for liquid water to exist on the surface. “The only life we know about is our carbon-based life, and water plays a crucial part in our own existence, and so it’s only natural that we direct our attention to planets in locations capable of having liquid water,” Professor John Webb of the University of New South Wales said. Finding a planet like ours is no easy job but there are people from all over the Earth who are devoting their time and money to find other planets out there. Humans have detected 1780 Goldilocks planets in the entire universe, and 16 in our star’s habitable zone. Once we obtain the technology to travel to and colonize the planets we will make our ascent towards a multitude of planets capable of living.
