And another qustion which goes like this:
The sun is burning since billions of yrs. It has released tremendous amount of energy since then.According to Einstein,energy release is the result of mass lost. That means sun is continuously losing its mass since billions of yrs. According to Newton F= m1.m2/ d.d
Here the mass of the sun i.e. m2 is decreasing.And ultimately the value of F will be decreased. But still the sun is attracting the heavenly bodies with the same force..The earth and other planets have not yet left their orbits. How is this possible????How is it still balanced?????

That's not a valid question. Belief in Science is not required, because Science has and requires evidence to back up all it's claims. It's like opening a book on the plays of Shakespeare and saying you believe that the little symbols you see in the book form words. If the book could feel emotions it would not care whethor you believed there were words inside it or not, because your belief or your disbelief has no effect either way.
The closest you can say is whethor or not you agree with the conclusions the scientific community has derived from the evidence.
As for why we're still attracted to the sun, yes you are correct in that there is mass lost with the hydrogen nuclear reactions taking place, but the mass the sun loses is very small in comparison to the mass of the sun.

'But still the sun is attracting the heavenly bodies with the same force..The earth and other planets have not yet left their orbits. How is this possible?'
The force is proportional to the masses, therefore the attraction is less than in antiquity. If the sun has been burning for four billion years and could be halfway through it's life, then in the 5,000 or so which we have had cvilization, we have seen a lessening of the suns gravity by 1/1,600,000 or 0.000063%... a pretty insignificant amount.
Of course, some stuff falls into it, and that would increase it's mass.

The reason the planets have not been affected is because the mass loss is negligible. It's an absolutely tiny amount compared to the whole sun. Just because there is mass loss doesn't automatically mean the planets are doomed to fly away. Remember, the sun is enormous. Around 99% of the matter in the entire solar system is contained within the sun. For the record, yes, I believe in science.

What makes you think that the orbits of the planets (and almost everything else in our solar system) is stable?
Actually the orbit of the earth is diminishing slowly as is its rotational speed. However, as stated previously, the loss of mass in the sun is negligible compared to the energy emitted.
On an atomic level, if you apply Einsteins theory of general relativity (E = mc^2), you will notice that the energy output to be enormous as compared with the loss in mass.
However, the energy emitted on an atomic level is negligible compared to the energy released on a quantum level - this energy is almost beyond comprehension.
Most of our physical laws "break down" on the quantum level and that is what physicists are trying to reconcile in a Grand Unified Theory.
What is the question about believing in science? The answer to this question is more philosophical than physical. If one believes in reality being the total of human experience, then science is a fact. However, if quantum physics is considered, it may be that reality is nothing more than a subjective notion conjured in one's own mind and may only be an illusion - - ???

believing is opinion diverted from logic
scenic is about fact
[and the mass lost is tiny compared to the entire sun]

Yes, I believe science exists.
Oh, you meant do I believe in scientific findings? Yes, I do.
As for your second question, no clue.

I believe in science because there would not be cures to medical problems
