How Our Brains Work

Every single animal that you can possibly think of – including fish, tigers, cats, and dogs – has a brain. Brains are among the most important parts of their bodies. However, a human brain is a little bit different. Although our brains are just as important for our bodies as animals’ brains are important for their bodies, our brains are different. Sure, it is not the largest organ in our body, but our brain gives us the power to think, speak, and solve problems. Because of that, brain truly is one of the most amazing organs in a human body.

A human brain performs all sorts of different actions. It controls the body temperature, and it handles all the physical movement that walking, standing, talking, and sitting require. Our brains also allow us to think, dream, reason with other human beings, and experience all sorts of different emotions. Without a brain, we wouldn’t be able to see, hear, talk, taste, or even touch anything that is around us. Although it almost seems unimaginable, all of these tasks are coordinated, controlled, and regulated by one small organ called brain.


Have you ever wondered what brains are made of? Well, the answer to this question is actually pretty simple. A human brain is made of 100 billion neurons. These neurons have the ability to transmit electrochemical signals from our brains to our bodies and vice versa. Think of this as your computer’s ability to send and receive information. Although neurons share the same characteristics as all the other cells in your body, what makes them unique is their ability to transmit signals over long distances.


Many lower-class animals – such as fish, birds, and reptiles – don’t really think to much. They are mostly focused on eating, drinking, sleeping, and reproducing. All of these are instinctual processes, which means that they don’t need to think too hard in order to perform these actions. Human beings perform all of these actions as well, and just like animals, we rely on our instincts rather than our ability to think.

Spinal Cord

The spinal cord and brain are not really the same thing. However, that doesn’t mean that spinal cord is any less important than the brain itself. The spinal cord is a downward extension of a brain stem, which basically means that it connects the brain to the spine. It contains some very important things, such as motor and sensory pathways from the body, and it has its own reflex pathways.

What Science Has Taught Us About Black Holes

Black holes are massive, scary, and destructive. These three characteristics are not really popular among the folks that live on planet Earth. However, we are not talking about the planet Earth here – we are talking about universe. Although the concept of black holes has revolutionized the world of science, it has also surprised people with its unique properties which somehow don’t agree with the general laws of nature that we all know and love. We are pretty sure that you already know who Stephen Hawking is. Well, he once said that fact is sometimes stranger than fiction. So, how is this statement connected to black holes?

Black holes have been an inspiration to many different movies and TV shows. According to Wikipedia, black holes are regions of space time from which gravity prevents anything from escaping, including light. Now, we know that Wikipedia sometimes cannot be trusted, but when it comes to black holes, pretty much anything that you read could be true. That being said, here are some things that science has taught us about black holes!

Black Holes Connect Us All

The binding force behind all those galaxies in space has always been a question that scientists could not really answer. However, many people think that galaxies are held together by large black holes which are located in their centers. The gravitational force keeps all those galaxies and stars intact and in the right position. When two or more galaxies collide, their central black holes become more massive. The main point that you need to remember here is that black holes hold the systems intact, as well as ensure that they stay in the right position. But then again, more research is required in order for this to be 100% confirmed.

They Are Large Memory Devices

Nothing that gets inside of a black hole can be accessed from the outside. But this does not mean that the matter is lost or destroyed inside of a black hole. However, the matter might never be the same again. It is like burning a magazine – although the information is not lost, it is pretty hard to read. Black holes really are mysterious, aren’t they?


Just like human beings, black holes can get obese. Obese black holes are known as supermassive black holes. There is absolutely no limit to how large a black hole can become. Logically, the larger the black hole is, the more space it takes up. Scientists believe that supermassive black holes play a very important role when it comes to preventing galaxies from becoming bigger.
