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)
