The Whanganui River in New Zealand   ( Actual Picture Taken from Google) There are hundreds of thousands of rivers in the world, but this is only one river that has all legal right equal to any alive person has in the country.  It is a relatively short river, flowing 180 miles through New Zealand’s North Island. But it isn’t just  any  old river. In all over the world this only river has been considered extremely sacred ground by New Zealand’s indigenous people, the Maori, for many years. So sacred, in fact, that the New Zealand government in 2017 decided to declare it  a legal person.   No one dare destroy or dames it. That’s right, the Whanganui River has been given all the legal rights and powers of a human being. What this means is that, if people pollute or tries to neglect the river, those people can theoretically be charged with assault (alternatively, the river itself can sue the person or also sue for damages). Even more surprisingly, if a person ...

These are 10 interesting facts about the human body. 1. It is very much surprising to note that the distance that a spermatozoon travels between the entrance of the vaginal canal and the fallopian tubes is proportional to the distance of 434 kilometres for an adult human. 2. There are a few people who know that their brain is sometimes more active when they are sleeping than when they are awake. 3. More or less the average person has 67 different species of bacteria in their belly button. 4. Every human being loses about 4kg of skin cells every year. 5. Almost every baby does not shed tears when he cries until he or she is at least one month old. 6. The human brain gets triples in size in the first year of a baby's life.  7. Every second, our body produces 25 million new cells. This means that, in 10 seconds, we will have produced more cells than the number of inhabitants in Brazil. 8. Our blood makes up about 8% of our body weight. Surprising? 9. Everybody's left lung is about...

Does light have its mass? If it doesn't have any mass why it is affected by gravity?  This is an exciting and wonderful question. Let's clarify a couple of things first with an explanation given by a professor of Physics. It is a fact that light bends by the effect of gravity; That is a fact. Light has no mass; thanks to this it can travel at the speed at which it does. E=mc^2 If light travels in a straight line, so  why does it curve? All right. Isaac Newton , first, suggested that the gravitational attraction between two bodies was proportional to the product of the masses and inversely proportional to the square of the distance between them. Or , simply put; dough attracts dough. Newton gave us the formula to calculate this attraction, and we thank him to this day for it. However, much later, in the year 1915, a great physicist postulated the " Theory of General Relativity ". He was Albert Einstein. He suggested that gravity is not an attractive force between two b...
