What is the true purpose of science?

The true purpose of science is to first understand nature and next help humanity.

Did present science help us to understand nature completely?
No, there are so many gaps in between science and nature. There are so many mysteries and questions about nature.
First we don’t know the clear basic of atom.
Present basic laws of science are only best module for our observation, but these basic laws don’t explain what the reason for our observation is.
Present science is very good in the field of electronic science; Electronic science is 95% man made science.

Some of the mysteries about nature

What was the true reason for cause of ice age at the time of high temperature in sun? What is the true reason for present global warming?
Truly what is true mass and truly what is gravity?
Truly what causes anything to have mass?
What is true reason for accretion disc jets such as the nuclei of alive galaxies emit relativistic jets along their polar axes?
What is the true reason for pioneer anomaly, what cause the apparent residual sunward acceleration of the pioneer space craft?
Did, compass is truly showing only earths magnetic field and what is the true reason for changes of earths magnetic field for many times?
What is true reason for sea floor is spreading only at center of ocean?

What is reason for tilt of 11 degree in our earth’s magnetic field?
What is true reason for Pluto's orbit is highly eccentric. At times it is closer to the Sun than Neptune (as it was from January 1979 thru February 11 1999). Why Pluto rotates in the opposite direction from most of the other planets? Truly what is black hole?

Ok, let us create an end to all of our mysteries about nature and science by true science.
Let us start our next level of science by true science.
