I like this question. I will continue asking until someone answers correctly.

P.S. The answer is not that they bounce back in opposite directions because reversing course involves a momentary velocity of zero, during which the objects (even if only infinitesimally briefly) are stopped.

i have heard about some very minute particles called 'GRAVTONS' which are spreaded over all the matter of the universe. It is some property of these gravitons due to which they attract things on which other gravitons are lying.

If I were superhuman and could jump to the moon, the earth would definitly rotate whilst up there, so is there a sliding scale? I can't imagine that it is a case of the answer being "No, because I am within the earth's atmosphere" as that would gradually decrease so there can't be a line at which a jump 1m above the earth rotates, and 1m below the earth does not? And if it is a sliding scale, then I imagine the case is that it would rotate at such a low level as not to be noticable, else it is negated by local air resistance?

I know the formula but can't derive it from the Newton-Raphson's method of finding roots of f(x)=0.

the formula that I know is x1 = x0 - k * f(x0) / f`(x0)
where k = number of times a single root is repeating for f(x) = 0.

plz help!!

to the production of heavy elements necessary for life. The first stars formed how long after the Big Bang? Then it would have been a further stellar generation, right?

So, how long would that be? Maybe 5-6 billion years?
