Galaxies, Blackholes, and The Universe

Question 1

The two/three types of galaxies

Answer 1

• ellipticals: the beginning form of a galaxy
  -spirals/pinwheels:Older and fully formed galaxies.

Question 2

Contents of Galaxies

Answer 2

• stars
• planetary systems
  -nebulae
  -dust/debris
  -black holes or quasar/pulsar stars
  -Dark Matter

Question 3

Formation of Galaxies

Answer 3

Started out as a proto-galactic cloud and then experienced a massive collapse that formed the the galaxy’s unique shape. Collisions and absorption of other smaller galaxies allows the galaxy to grow.

Question 4

The Great Attractor

Answer 4

A supermassive black hole located in the middle of any galaxy that either attracts or repels millions of galaxies.

Question 5

The Four Fundamental Forces/the Superforce

Answer 5

1. Strong Nuclear
2. Gravity
3. Weak Nuclear
4. Electromagnetism

Question 6

Functions of matter

Answer 6

Attracts planets, stars, galaxies, etc together.

Question 7

Characteristics of matter

Answer 7

Protons-positively charged particles.
Neutrons- neutrally charged particles
Electrons- negatively charged particles.

Question 8

Anti-Matter

Answer 8

The complete opposite of matter which repels planets, stars, galaxies, etc from each other.

Question 9

Characteristics of Anti-Matter

Answer 9

Anti-Protons(opposite of protron)
Anti-Neutrons(opposite of neutrons)
Positron(opposite of electrons)

Question 10

Black-holes

Answer 10

A hole in space that is formed from stellar and galactic collision. Gravity is so strong that everything gets pulled in and is can absorb light.

Question 11

Event Horizon

Answer 11

The circumference around a black hole, and the boundary within which antying will be consumed. The bending of space-time occurs here.

Question 12

Point of Singularity

Answer 12

Regions of space where the density of matter or the curvature of spacetime becomes infinite.
(the middle of black holes.)

Question 13

Quasars

Answer 13

A phenomenon when a black hole ejects all of it’s matter in a spherical shape.

Question 14

Dark Matter

Answer 14

Simply anything with mass/gravity in space that we cannot see.
Examples: anti-matter, Black Holes, voids.
Helps in the expansion of the universe.

Question 15

The universe began…

Answer 15

As a hot and infinitely dense point(Similar to a black hole), which then expended wider into space.

Question 16

The “Big Bang” created

Answer 16

Matter, space, and time.

Question 17

Two major evolutionary points of the universe

Answer 17

Radiation Era- The era where everything but matter was formed.(Lasted only mere seconds)
Matter Era- The era where matter and everything else was formed.(Took a significant amount of time)

Question 18

Planck Epoch

Answer 18

A period of time within the radiation Era- of the universe where only energy/light and super force/movement existed.
This period of time ended when gravity split away from the superforce

Question 19

Matter was formed when…

Answer 19

gravity split away from the superforce and started the Matter Era.

Question 20

The Grand Unification Theory

Answer 20

The theory that gravity split away from the superforce, leaving only three forces left.

Question 21

Electroweak Force

Answer 21

The force of weak nuclear and electromagnetic forces.

Question 22

Hadron Epoch

Answer 22

The period of time in the Matter Era when the strong nuclear force split away from the superforce and formed positive and neutral charged particles.

Question 23

Lepton Epoch

Answer 23

A period of time in the matter era where the cooling temps of protons and neutrons allowed them to stabilize and form a nucleus.

Question 24

Nuclear Epoch

Answer 24

The period of time in the matter era when the nucleus of the first element was formed.

Question 25

The first formed element

Answer 25

Helium

Question 26

Atomic Epoch

Answer 26

The universe was able to produce enough charge to make the second formed element of hydrogen, helped to guide the universe into the stellar epoch.

Question 27

Stellar Epoch

Answer 27

Began with the first two elements were able to form almost all other forms of elements and made the creation of stars.
Hypothesized to end when all stars lose their energy and wink out into existence.

Question 28

White Holes

Answer 28

The opposite of black holes that reflect light and ejects it’s gravitational force outward.

Question 29

Worm Holes

Answer 29

The theoretic(yet to proven true) model of time bending, starting from the black-hole and ejecting out of the white-hole on the other side.
