What A Genergetic Day

Haha... Today physics enters chapter 7 already - Gravitational Force.
I do not know why today i am so energetic.
Maybe yesterday i chat with she.
Haha... Jumping the topics already.
My Physics teacher has talked about the gravitational force not yet can be explained.
It is too wide, the gravitational force includes many types of energy.
And the scientists still not yet found the solution to explain.

'If a apple can drop from a tree to the ground,
why the moon will not drop into our Earth?'
Teacher said.
And at the moment, my mind comes out many question.
Is inside the Earth is a small sun?
Every star inside contain a sun?
The moon is dropping but in a very slow motion due to the force of attractive by the other sun?
Too many question.
But I cant gain a solution...
Because what am i learned is limited.
If i want to know the detail, I need to continue study.
To search for the truth.

Haha...
Physics is tough and got a lot of calculation.
if want to master physics,
Not easy.

Meanwhile, I have ask her for dating.
And she accepts the offer from me.
But i am not sure is that good?
Haha... Who knows?
The world is full with up and down,
We cant predict anythings.
