I understand that this is more of a philosophy subject, but since there isn't a /phi/ I'll ask here.

What sets the rules of the universe ? Why does mass attract each other ? Why is the maximum speed of matter can't go above 300,000 km/s ? Is there a fundamental single smallest indivisible building block of matter or can it divide forever.

When did everything start ? There must have been something there to previously trigger the initial action to start all this. Which means there can't really be a starting point in time since it always needs a previous action.

And lastly, why is there something instead of nothing ?

I know a lot of these questions are impossible to answer, or they simply just don't have an answer. But I don't even know where to start in order to answer to these.

>When did everything start?
The observable universe began in a big bang approximately 13.7 billion years ago

>Why does mass attract each other ?
Because space-time curves in the presence of matter/energy

>Why is the maximum speed of matter can't go above 300,000 km/s ?
Actually, all particles would go at this speed if they didn't interact with the Higgs field. So, it's just a fundamental constant of how fast massless particles move through spacetime.

> Is there a fundamental single smallest indivisible building block of matter or can it divide forever.
The Standard Model of physics suggests that fermions and bosons are the smallest constituents of matter. String theory suggests that tiny hyper-dimensional vibrating strings are.

> There must have been something there to previously trigger the initial action to start all this. Which means there can't really be a starting point in time since it always needs a previous action.

Not necessarily. Read what quantum physics has to say about causality and watch "A Universe from Nothing" by Lawrence Krauss.

>why is there something instead of nothing ?

Because Quantum vacuums are unstable.

Your lack of physics knowledge is showing.
Conservation of energy isn't a fundamental law of the universe, it is derived for systems with certain type of symmetries. This shit is literally known by an senoir physics student, and is covered in the most basic classical mechanics books.
