Now we know, how nuclear fusion works. After severall lifetimes of suns, which died and formed new stars from their material. It also happened that solar systems have formed, you can say. First there where only a sun, it died exploded in most cases and spread the new fused atoms across its enviroment.
Planets could form since the most atoms formed in this kind of phenomena, the first solar systems have formed but thats not special. Like it had to happen, and not otherwise ^^.
since I live on the earth in our milkyway, i know there might be other life forms outside our solar system. But im not here today to tell you where you are, its all relative because you move, the earth moves, our solar system moves and etc. or where other life may be. Thats something no one conquered ever and i wouldnt know how to react. Well Physics is the science subject which tries to explain what and why it happens. So lets start with Classical mechanics or Classical physics.
A good point to start with is Isaac Newton who inveted Calculus, a mathematical tool, since physics describes our live maths is the bedrock foundation of it, i mean you learn how to read, count and etc but you did it all on paper now you have to count how much money you have or how much something weighs. Newton also set some law of motion like the 3 axioms he derived and the laws of the universal gravitation and did research in the optics and and waves, like sound moves trough the air or on water surfaces, waves describe how energy passes trough a medium. One other brilliant man found that Electric Fields and Magnetic Fields behave in the same way and combined them into the Electromagnetism theory which was James Clerk Maxwell. He proposed that light would be an Electromagnetic wave. One other big region in classical physics is Thermodynamics how energy passes from one form to another.
Somehow Energy makes a big deal in the world of Physics well since Einstein said that energy is euqivalent to matter multyplied by the lightspeed^2, without Energy there would be like nothing, pure nothingness i think then there wouldnt be even Dark matter and so on. Next Blog will be about General Relativity. Keep your heads up :)
