Gravity - Not A Gentleman

Sunday, November 02, 2014 Posted by Arun Vishwakarma , , , No comments
Gravity is the building force of the Universe. At first sight it looks very gentle. It is always attractive in nature and the weakest force in nature. It is the gravity which attracted all the dust and hydrogen atoms to form clouds which then resulted into the formation of stars, planets and galaxies of which we are a part. We can say that gravity is the driving force of nature.

More mass more gravity. Gravity is the mother force behind all the happenings in this Universe. But sometimes it becomes intolerable. When gravity is at its peak it discards all the other forces and dominates over them and that is what we observe inside Black Holes. For a star whose mass(min. req.) is thrice the mass of the Sun, it results into a Black Hole. Inside the Black Hole lies Singularity, a place where space-time framework depress to infinity and gravity is so strong that not even light can escape. In simple terms singularity is just gravity gone mad.

Singularity is hidden inside an Event Horizon and  anything which goes inside remains inside. For a layman the escape velocity exceeds the speed of light and from General Relativity nothing can breach the speed barrier thus, once inside it's impossible to get outside, not even if you're light.

At Singularity gravity is so strong that all the matter collapse in a pin point denying all the known laws of quantum mechanics. Well a new super matter can be observed there in which all the sub-atomic particles are being forced to share the same quantum state simultaneously overlooking the Pauli's Exclusion Principle. At Singularity Space-Time bends to infinity. All the existing laws of science fails here. Singularities or say Black Holes are abundant in our universe and their sole existence is a question to the entire science community. They exist so it must be some physics working there supporting its existence which we don't know yet and this opens the gate for new discovery. To define Singularity we need a whole new branch of science with a whole new set of theories and concept. One thing which we need is the Quantum Gravitational Data which we don't have yet but not for long.

Consequences of Approaching "c"

Saturday, June 28, 2014 Posted by Arun Vishwakarma , , , , , No comments

First of all we should know that nothing but light itself can travel at speed equal to "c". It's physically restricted to get to the speed of light unless you are not light or you're massless. But for instance let's imagine if we could anyhow approach "c" then, what the consequences will be that we have to face.

(a) Length Contraction : As any object approaches "c" its length starts to contract. At "c" length of the object becomes infinitesimally small that it becomes invisible. So, if any of you wants to vanish start running and get that speed.

(b) Time Dilation : As we approach the speed of light, time tends to slow down and it stops exactly at "c". For example if two person set their clocks and one of them takes a rocket, zooms into space at speed of light and then returns after 10 yrs.. then the one who was left behind on earth will be 10 yrs. older than the one who flew away. And this is the twin paradox. This happened because in the Earth's frame of reference time had no meaning for the person who was flying in space at the speed of light. So, if any of you ever want more time to study for exam or wants to gaze into future, get your bike and accelerate it to "c".
(c) Mass : As an object approaches "c" its mass tends to infinity. For instance a dust particle of mass 0.000001 gram if allowed to accelerate to speed of light, its weight will start increasing and reach infinity which is physically not possible because it will require an infinite amount of energy(E = mc2) which is scientifically impossible to generate. So, if any of you wants to increase your weight just drink Glucose and run at speed = "c".

There are much more things but for now that's enough for you all to understand that why can't we approach "c" and if we somehow did, then what would be the consequences we will face.
