Creation of Singularity
Hypothesis - a supposition or proposed explanation made based on limited evidence as a starting point for further investigation.
“It does take great maturity to understand that the opinion we are arguing for is merely the hypothesis we favour, necessarily imperfect, probably transitory, which only very limited minds can declare to be a certainty or a truth.”
This is what I create. A hypothesis to start with has several loopholes in it but is used as a foundation for several other foundations in Physics or any other subject.
Newton's law of gravitation states that the force of gravitation between two bodies is :
GMm/r^2
Now if we take a star, for example, it is a perfect sphere. If we consider it deeply we can divide it into two spheres
1) The outer surface and
2) The core
Both the spheres share a common centre of mass. This means the radius of the distance between the two centres of Using this in the formula we find that the gravitational force is infinity.
Due to infinite gravitational force, the star collapses into an infinitely small object called singularity whose size tends to zero and gravitational force is infinity.
We know that whose gravitational influence is not much high their shapes aren't completely spherical more of elliptical. Now the concept of my singularity will be possible in a completely spherical object which is mostly a huge gigantic star.
For being completely spherical we use Chandrashekhar Limit of 1.44 solar masses.
Thus this explains why a singularity has infinite gravity and infinitely small size.
However, every hypothesis has a loophole in it and I ask my fellow readers to spot out a few.

How you have deduced that the gravitational force is infinite is absurd. Newton's law is about two bodies but here you have considered a single body ... Dividing a body into the outer surface and the core in this case seems a bit absurd because both, if considered seperately, have the same centre of mass... And are a part of the same system. It will definitely sound absurd if I say that earth exerts gravitational pull on itself, right? And when Newton formulated the law, didn't he already figure out that when radius is zero... The law won't hold for sure .
ReplyDeleteOur current view of dividing anything by zero is considered as infinity.
DeleteHere we use the concept of system and surroundings. If you consider The star as a whole then the star became a system but if you consider the core and the surface of the star both of them become individual systems which is what I considered for the above mentioned theory. As for your next point Everything exerts gravitational pull over itself. Consider a collapsing star, now if it didnt exert pull over itself towards the centre then how would it collapse? As for Newton even though he knew about the flaw in his theory, the infinite gravitational pull and infinitely small size of a singularity due to zero radius can't be denied.
Now when you talk about Earth exerting a force towards itself, the core of Earth exerts gravitational force towards the crust keeping it in place and not drifting away in space.
DeleteAnd I couldn't understand how the mass of a huge or gigantic star can be zero. Would be really happy if you'd explain that ..
ReplyDeleteIts a mistake on my part for its a typo. But take the formula, If the radius is taken towards the other side and multiplied with the gravitational force and the 'G' is taken to denominator for dividing by zero, m1*m2 = 0 which implies either pf the masses are zero or both the masses are zero. I hop I have cleared the misunderstanding.
