Space and it's wonders
The universe is not stagnant; it is constantly evolving and growing in all directions. Scientists discovered almost a century ago that it is expanding, and at an increasing rate. As a result, stars, planets, and galaxies are moving farther apart, leaving more space between them. This expansion should cause the universe to become colder, as it was much denser and hotter during the Big Bang. However, recent observations have shown that the universe is actually getting hotter. Cosmic gas temperatures have increased by over 10 times in the last 10 billion years, reaching temperatures of around 4 million degrees Fahrenheit. Gravitational force plays a role in pulling gas and dark matter together to create galaxies and clusters of galaxies, which results in chaotic and messy processes that heat up more gas. Scientists are monitoring this situation closely, measuring cosmic gases using redshift to track temperature changes.

Ok! Firstly, brace yourself as I am about to blow your mind with things that we talk about everyday. Most probably are in our day to day vocabulary. Can you believe me when I tell you that there is no such thing as a baby carrot? The small carrots sold in supermarkets are regular carrots that have been shaved down to a smaller size. I know this makes no sense at all since we all know strawberries are red in colour but truth is that strawberry flavoured gummy bears are usually green, not red or pink. The people in agriculture obviously know this, in fact if you know a this or two about the farming of rice you might know that, brown rice and white rice are the same product, but white rice has had some parts removed through milling to give it its white colour. This for me was mind blowing. The Great Wall of China was built using sticky rice soup mixed with lime to create a stronger mortar. Chocolate lovers here is a fun fact for you. A dusty film found on old chocolate is caused by the cocoa butter separating from the rest of the bar due to heat, but the chocolate is still safe to eat.
