✰The Possibility of Extraterrestrial Life✰

Ancient Alien Theory

Their is an ancient theory that extraterrestrial life (Aliens) have landed on Earth thousands of years ago. This theory didn't become famous until the 1960's when their were many sightings  of UFO'S. The ancient alien theory states that aliens landed on Earth to interact with humans and teach them about the us e of technology and the belief of religion.

A famous ancient alien theorist, Von Daniken, found two types of evidence. The first type of evidence is ancient text of religion speaking of a higher power. The second type of evidence Von Daniken points out is ancient artwork. Their has been ancient artwork found that resembles alien-like figures. This theory would explain a great deal of all the mysterious questions that people have like, "how were humans able to calculate and make the pyramids perfectly when we weren't advanced enough to do so?"

Say aliens really did land on Earth to interact with humans. i think it's very possible, but what if they interacted with us to give us a sign of greater intelligence and warn us about the future that resulted into conspiracy theories. 

✰Supernovae✰

Exploding Stars

Supernovae are exploding stars that occur at the end of a stars life. A Supernovae has 10 times more energy than the sun releases every second.

When a star explodes it lights up the whole galaxy for a brief moment.  The supernovae is so bright it takes weeks and maybe months for the light to fade away.

In a galaxy the size similar to the Milky Way galaxy their is one supernovae every 50 years on average. When the supernovae occurs all the elements in the star and radiation from the star burst out into the universe traveling at a high speen at 30,000 kilometers per second. Not all stars explode though, it's said to be that our sun will never explode. But stars 10 times bigger or even 100 times bigger will eventually explode and make a supernovae.

✰Earths Moon✰

Earth's moon:

• Earth's moon is named Luna.
• The distance from the moon and the Earth is 238,900 miles.
• Earth's only natural satelite.
• Earth's nearest cosmic neighbor
• The moon was created from a rock the size of Mars slammed into Earth around 4.5 billion years ago.
• An Apollo 14 astrounaut took seeds with him to the moon and later the seeds were sprouted on Earth. They are called the moon trees, and we have more than 400 of them.
• Their may be another moon, they have found an astrounaut stuck in Earths gravitational grip.
• The moon has many craters from space rocks from 4.1 billion years ago and 3.8 billion years ago. These craters have not eroded because earthquakes and volcanoes do not destroy the surface as it does to Earth's surface. 
• The moon has no atmosphere like the Earth does.
• The moon is shaped like an egg.
• The moon may have a core, hot and molten, like Earth.
• The moon has moonquakes. (the moon shakes)
• Some people think the moon is more of a planet.
• Moons gravity pulls on the Earth's ocean.

Phases of the moon:

• New moon
• New crescent
• First quarter
• Waxing gibbous
• Full moon
• Waning gibbous
• Last quarter
• Old crescent

✰black hole✰

BLACK HOLE

Black holes are a huge mystery of the universe.  

A black hole has a very strong gravitational pull that NOTHING we have discovered, not a particle nor a electromagnetic radiation can escape from the black holes gravitational pull. 

The theory of how a black hole is created is that it was created by a sufficiently compact mass that deformed spacetime. 


Facts on black holes:

• It's impossible for us to detect a black hole with the instruments we have, scientists detect them by using how the outside enviroment is acting.
• There is a possibility of a black hole being in the center of our galaxy, The Milky Way. Although our planet appears to be in no danger from how far away(about 2/3rds) we are from the black hole.
• NASA says that they may have discovered three types of black holes. 

-primordial black holes: which are the smallest kind we have detected.

-Stellar black holes which are 20 times more massive than our sun!! and are said to be the most common type.

-The largest Black holes we have discovered are called the supermassive black holes. They are more than 1 million times more massive than our sun!!!!!!!!

✰Multiverses✰

Multiverse is an infinite realm of being or potential being or which of the universe is regarded as part of instance.

THE BUBBLE UNIVERSES THEORY

"A multiverse is a theory that states that there are multitudes of universes, each formed entirely randomly with our universe being one of the only or one of the few to support life."  (gotquestions.org)

The theory of the universe is that it's flat and infinite. Scientinsts say that if the universe is infinite it has to start repeating at one point, and that is where the theory for multiverses come in. If there are universes eventually repeating itself then there is a possibility that with every universe there is another Earth, maybe another you. Maybe that universe has either a more evolved or less evolved Earth. 

✰Galaxies✰

Galaxies are a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.

Types of galaxies:

• barred spiral galaxy
• irregular galaxy
• spiral galaxy
• peculiar galaxy
• elliptical galaxy
• lenticular galaxy

-Barred Spiral Galaxy

Barred Spiral galaxies have a bar shaped structure located in the center of the spiral galaxy. Bars effect the motion of stars and interstellar gas in the galaxy.

-Irregular Galaxy

Irregular galaxies used to be a spiral galaxy or elliptical galaxy but the gravitational pull effected the galaxy and disformed its figure. They are among the smallest galaxies in the universe and are full of gas and dust. the irregular galaxy has no particular shape due to its disformity, the stars within the irregular galaxy are bunched up and have random patches throught the galaxy.

-Spiral Galaxy

Spiral galaxies are a flat rotating disc containing stars, gas, dust, and in the center of the galaxy is a bundle of stars known as the bulge. The spiral galaxy is the most common type of galaxies in the universe.

-Peculiar Galaxy
Peculiar galaxies are not normal galaxies. 
There are two types of peculiar galaxies:

• Interacting Galaxy- Interacting galaxies have been affected by the gravitational attraction of neighboring galaxies.
• Active Galactic Nuclei- These galaxies have a much higher luminosity, than most galaxies, of the electromagnetic spectrum.

There is a scientific theory that the peculiar galaxy is a result of a merge of two regular galaxies.

-Elliptical Galaxy
Elliptical galaxies are the most abundant types of galaxies but their age and dim qualities. They are often hidden compared to younger and brighter stars.

-Lenticular Galaxy
"A Lenticular galaxy is a type of galaxy which is intermediate between an elliptical galaxy and a spiral galaxy in galaxy morphological classification scheme." (wikipedia.org)

✰The Big Bang Theory✰

The Big Bang Theory Theme Song
"Our whole universe was in a hot dense state,Then nearly fourteen billion years ago expansion started. Wait...The Earth began to cool,The autotrophs began to drool,Neanderthals developed tools,We built a wall (we built the pyramids),Math, science, history, unraveling the mystery,That all started with the big bang (Bang)!"Since the dawn of man" is really not that long,As every galaxy was formed in less time than it takes to sing this song.A fraction of a second and the elements were made."

The Big Bang Theory is the explanation of how the universe began. In the 1920's the big bang theory originated from a belgain priest (Georges Lemaitre). He suggested the big bang theory when he theorized that the universe began from a single primordial atom.


It is believed that before the big bang theory the whole universe was compressed into a hot dense mass around 13.7 billion years ago!


The Big Bang Theory was not an explosion in space as most think the theory is about, it actually is just an appearance of space in the universe.
