Exploring our Universe

One Geometric point

Exploded 12 billion years ago and universe expanded

Hydrogen, helium, and lithium formed from the simpliest of particles

Matter was not uniformly distrubted, causing formation of uneven clumps then galaxies then large objects then planets

Matter came together but undistributed due to gravity to form large objects

Nuclear fussion converting hydrogen into helium started forming light and heat and therefore sun

Elements formed due to nuclear reactions

Explosion of star releasing large amounts of energy

energy released from star form matter

formed solar nebulae ( galaxy)

Matter would pile due to gravity to form dust , dust to rocks, rocks to lumps, lumps to planetesmials

Hot ball of rock, iron catastrophe, molten iron sank to core

Electro magnetic field shielding against solar winds

Planet cools after collision with planet tesmails forming moon
