Major Facts Of Science In The World That Are Helpful


A solar eclipse occurs when the moon passes between the sun and Earth, blocking the sun’s rays from reaching Earth. Solar eclipses can only happen during a new moon, when the sun and moon are in alignment. A total solar eclipse is a rare event because it can only occur when the sun, moon, and Earth are perfectly aligned.

During a total solar eclipse, the moon’s shadow blocks the sun’s light, making it appear as though the sun has disappeared. The sky becomes dark and the temperature drops. Total solar eclipses are awe-inspiring events that have been revered by cultures around the world for centuries. Solar eclipses can be dangerous because looking directly at the sun during an eclipse can damage your eyes. It is important to use proper eye protection, such as eclipse glasses or a handheld viewer, if you want to safely view an eclipse.

Human Evolution

Human evolution is the long and complicated process by which humans have developed over time from early hominids to modern Homo sapiens. This process has involved a gradual increase in body size and brain size, as well as other changes in anatomy, physiology, and behaviour.

The first hominids appeared on Earth about 2 million years ago. They were small, bipedal apes with brains that were one-third the size of modern human brains. Over time, they evolved into larger and more intelligent beings. By about 200,000 years ago, they had evolved into Homo sapiens, or modern humans.

Today, there are billions of people on Earth, each with their own unique talents and abilities. We have come a long way since our humble beginnings as small apes. But our journey is not over yet – we continue to evolve every day!


Deoxyribonucleic acid, more commonly known as DNA, is one of the most important molecules in the world. It is the molecule that contains the genetic code for all living things. DNA is responsible for the development and function of every cell in our bodies.

Without DNA, we would not be able to exist. Every organism on Earth, from bacteria to humans, has DNA. It is truly a remarkable molecule.

There are many different ways to learn about DNA. You can read books or articles, watch videos, or even take a class on the subject. However you choose to learn about it, understanding DNA can give you a greater appreciation for the miracle of life. 

What is DNA?

DNA is a long, thread-like molecule that contains the genetic code for all living things. It is made up of four types of nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). These nucleotides are arranged in a specific order, which forms the "code" for our genes.

Our DNA is coiled up tightly inside our cells, and it is organized into structures called chromosomes. Humans have 23 pairs of chromosomes, for a total of 46. Each cell in our body contains a copy of our DNA.

What does DNA do?

DNA contains the instructions for our development and function. It determines what we look like, how our bodies work, and even some of our personality traits.

When a cell wants to make a protein, it first reads the instructions in the DNA for that protein. The cell then makes a copy of those instructions using RNA (ribonucleic acid). The RNA travels out of the cell nucleus and into the cytoplasm, where the protein is made.

This process is known as gene expression. It allows our cells to make the proteins

The Big Bang Theory

The Big Bang Theory is the most popular and widely accepted theory of the origin of the universe. It states that the universe began from a very dense and hot state about 14 billion years ago. The universe then rapidly expanded and cooled, resulting in the formation of stars, galaxies, and eventually life.

The Big Bang Theory is supported by a wealth of observational evidence, including the abundance of light elements in the universe, the existence of background radiation, and the large-scale structure of the cosmos. While there is still much to learn about the origins of the universe, the Big Bang Theory is an essential part of our current understanding of cosmology. 

The Big Bang Theory is not without its critics, however. Some scientists have suggested alternative theories, such as the Steady State Theory or the Plasma Universe Theory. However, these theories have not gained widespread acceptance and the Big Bang Theory remains the most popular explanation for the origin of the universe.

The Universe

The universe is an unimaginably vast place. It's so big, in fact, that scientists are still discovering new things about it all the time. Here are some of the major facts about the universe that are sure to blow your mind:

1. The universe is estimated to be around 13.8 billion years old.

2. It's thought to contain around 100 billion galaxies.

3. Each galaxy contains an average of 100 billion stars.

4. There may be billions of planets in the Milky Way alone.

5. Only a tiny fraction of the universe is visible to us with telescopes.

6. The rest of the universe is made up of dark matter and dark energy, which we can't see or detect directly.

7. The universe is constantly expanding, and will eventually end in a Big Freeze where everything becomes cold and lifeless.


Science is a huge part of our lives, and it touches everything we do. Whether we realize it or not, science is always at work, and it can be a great help in our everyday lives.
