Geography

It says that a long time ago there was a big explosion in which all of the space exploded, and mass of the universe, contained inside the singularity.The explosion was as big that it created time, shaped the laws of gravity, the forces that keep atoms and mecules together and the way electromagnetism works.

The Big Bang Theory

Think those galaxies started to grow around pockets of space that were slightly denser than their surroundings, an effect created by cosmic inflation when the universe began. But when it comes to the exact order of formation, they have a little bit of a “chicken or the egg” problem.Most big galaxies have supermassive black holes at their centers.It’s possible that the black holes came first, and galaxies grew around them. Or perhaps the galaxies came first, and small black holes within them merged and fed on gas, dust, and stars, eventually becoming the monsters they are today.

Galaxy Formation Period

After the Big Bang, the universe was like a hot soup of particles (protons, neutrons, and electrons). When the universe started cooling, the protons and neutrons began combining into ionized atoms of hydrogen (and eventually some helium). These ionized atoms of hydrogen and helium attracted electrons, turning them into neutral atoms - which allowed light to travel freely for the first time, since this light was no longer scattering off free electrons.

Our solar system formed from the gravitational collapse of a “dense” giant molecular cloud of gas and dust, composed mainly of hydrogen, a bit of helium, and about one per cent of heavier elements. After the cloud collapsed, the majority of the mass concentrated onto the centre, creating our sun

Sun Birth

The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.

Creation of the earth and moon

According to our current knowledge, planets are formed around a new star by condensing in a disc of molecular gas and dust, embedded within a larger molecular cloud. Condensation increases until they become giant planets, which are heated, then cleanse their orbits in the disc and possibly bend it
