It happened 15-20 zillion historic period ago. The universe, ahead it was the universe, began as an infinitely hot, dense, fireball which and so expand apace and became flooded with subatomic particles. Those particles thence slammed into one some other, operateing protons and neutrons. It then took another 500 deoxyguanosine monophosphate years for atoms to form. 300 one thousand million more years later, spark advances and galaxies began to form. Then finally, 4.5 billion years ago, our solar system and gravity formed. There is caboodle of evidence to figure that the Big blush Theory did in fact happen. S cientists ascertained radiation that would only happen from a huge explosion. Also, particles of debris and bodgees also show evidence of a massive explosion throughout space. Even though this is a widely accepted theory, there ar still more or less unanswered questions. Like, How and why did the universe expand? What caused the galaxies to form?

But, by chance the most daunt question is: What existed before the Big Bang? This shows that although this theory has some very convincing evidence, it is still a theory. Chapter 2: Star Life Cycles Even though stars arent living, they do in fact have life cycles. They are born and then they die. How! ever, not literally. Before stars are born, they pop off as part of a nebula which is cloud of gas and make clean. A star is born when the contracting gas and dust from a nebula sour so dense and hot that atomic fusion starts. A nuclear fusion is the process which atoms come to suckher and form heavier atoms. During nuclear fusion, enormous amounts of energy are released. How long a star lives depends on its mass.
