The Constellations

To people in the ancient world, they thought that the earth was flat and sky above their heads seems to be like a dome. The sun moves across it by day and the moon by night. At night also, the inside of the dome was surfaced with a lot of stars. The brightest stars were grouped into different patterns called constellations, which means “a group of stars” in Latin. The different pre-historic civilizations had different names for these different kinds of patterns. They often named it according to their beliefs(gods and goddesses) and also animals.

Before astronomical inventions like the telescope emerged, the great men of those times studied the stars in fine details. They were able to realize through observation is that these stars move in a steady procession through a course in each year. For example, some certain constellations appear above the eastern horizon in the spring.

Ancient people observed that within the procession of the stars,there were 12 of them of great interest. The sun and the moon always rise and set within the sky that withholds these 12 constellations.  These were called the zodiac which means “a circle of living things”. These constellations are called each by the names of Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpios, Sagittarius, Capricorn, Aquarius and Pisces. These are the signs of the zodiac. 

Other than the famous twelve, there are other thirty six constellations. But in the south, explorers were able to discover hundred more. Most of the stars were named after ancient things and also by ancient people like Arabian Astronomers who were living in Persia. Examples are Mizar Hamal and Deneb. Others were by ancient Greek which are Castor and Pollux. Nowadays, fifty seven stars are being used to be a guide by sea and air navigators around the world.

Ways The World Will End

No one really knows when the world will end. However, some scientists believe that it will take billion of years until we are all erased on the face of the Earth and then it will disappear. Nevertheless, we want to know what possible ways will the world end. Are you ready? Here are the interesting scenarios.

Zombies

The popular zombie television series The Walking Dead. Bringing the dead to be alive again is impossible. However, making a zombie-like attitude and behavior can be. One example is the rabies which we commonly get from dogs. This virus can actually make people violent. Another are parasites that can control your brain activity.

Asteroid(s)

Being hit by an asteroid can be close to impossible but it’s not totally. Earth has been known to be a target of roaming asteroids from the outer space. However, we were not yet hit by one that can actually cause destruction to our planet. The biggest one was in Russia were buildings were destroyed by the massive impact as well many people were hurt.

Complete Robotic Takeover

Technology has been developing rapidly nowadays. Now we have robots who can assist us with our daily lives like learning and also human-like technology. It wouldn’t be long until human beings can develop something that will have their own feelings and independent brain.

Global Warming

It’s true that the planet’s surface is getting. Even though we stop releasing greenhouse gases to the atmosphere, it will not stop the earth from warming up. Through statistics, more or less 150,000 people already died because of the issues relating to this condition and it will get more as years come by.

Big Rip Theory

If there was a Big Bang Theory there is also a theory on how the world end. This is that everything in the universe from bodies to planets will literally tear apart. As we know the universe is expanding but there will be a time that it can’t expand anymore and it will snap.

Now this is mean :
