ORIGIN OF THE UNIVERSE Creation Myth

A symbolic narrative of the beginning of the world as understood by a culture.

Handed down from generation to generation through oral traditions.

A system of ideas trying to explain something.

-Point blank, start black, start as nothing but due to a random explosion, Explosion that spent space, time, energy, and matter in all directions. Therefore it was the Universe. -Universe began 13.7 million years ago.

Unchanging and uniform in space. Density of matter is constant over time.

Explained the limitations of the big bang theory. It explains that the universe expands really fast, faster than light.

Comes from the modeling of subatomic particles. Tiny One string-like entities. The theory that envisions that a string undergoing a particular mode of vibration corresponds to a particle with definite properties.

-This theory that suggests one or both ends of the string are attached to a sheet on brane(membrane) -The origin of the universe occurs as a result of contact of 2 hyperdimensional branes.

FORMATION OF THE SOLAR SYSTEM

Gravitationally-bound system of stars, stellar remnants, interstellar gas and dark matter.

One of The billion galaxies in the observable universe.

Includes the sun, the planets, and everything that orbits.

SOLAR SYSTEM FORMATION THEORIES

Solar system was formed due to a whirlpool-like motion in the pre-solar materials

The planets were formed by the collision of the sun with a giant comet.

great cloud of gas and dust;

great cloud of gas and dust; Nebula, collapsed due to gravitational pull.

-Sun and planets were produced by different mechanisms. -Planets were formed from the substance that was torn out of the sun. Speeding massive stars passed by the sun, The condensed material became the planets.

Solar Nebular Theory -Formation of the planets involves different stages.

Grain-sized particles

Massive objects unite from planetesimals

STRUCTURE OF THE EARTH

2 types of Core

2 types of Mantle

2 types of Crust

-It has a temperature of 6000°C, as hot as the surface of the sun. -Mostly Solid -Made of Iron and Nickel

It is the Earth’s Center

Cause of the earth’s magnetic field -4000°C - 5000°C -Liquid -Made of Iron and Nickel

Intermediate layer of the earth. -Made of Magma -Thickest Layer of the Earth(2900 km)

Made up of molten rocks

Asthenosphere -Exhibits Plasticity -Soft/Magma -Convection Currents -2240km

Lithosphere -Rigid/Solid -Moho Boundary -660 km

a thin layer, where dry, hot rock from the deep earth.
