Point of No Return - The Event Horizon

An Event Horizon for a layman, is an outer covering of an extreme astrophysical phenomena known as Gravitational Singularity. Just like a magnet has its magnetic field, Singularities have a gravitational field. Near the singularity escape velocity is much much grater than the speed of light but moving away it decreases and at a certain distance it is exactly equal to the speed of light or "c"(say). This one dimensional distance in 3-Dimension corresponds to a sphere which surrounds the singularity and known as the Event Horizon. Since the escape velocity is greater than the speed of light and nothing can cross the speed barrier so it is a one way route to the centre and also known as the Point of No Return.



It makes impossible to see inside a black hole or a naked singularity.

As an object or dust particles from comets, planets or even stars rotating around a black hole gradually reaches near the event horizon it starts gaining speed, breaks into pieces and gets heated up due to the collision between different bodies at high speed and thus forms Accretion Disk which in turn covers the Event Horizon up and makes it impossible to see it.

Event Horizon is the point where we observe certain events varying in properties than we normally observe in day to day life. Let's assume an Astronomer falling into a black hole. Closing into the event horizon he will experience tremendous amount of gravity. Gravity will change drastically from his head to neck to chest to other parts of the body that his body will be elongated and stretched infinitely and be torn apart.


The most interesting thing about this place is we can't see any object actually crossing the event horizon because of the General Relativity. The speed of the falling object is approaching "c" thus time is dilated to infinity. So the object, for an observer (in his frame of reference), will appear taking forever to fall into the black hole and will appear to have frozen to a stationary state and seize to go beyond. But in reality (object's frame of reference) it would have easily crossed the barrier and would have fallen into the singularity very long ago.

Now this property of gravity to dilate time could be harnessed to have a inter-planetary sling-shot into the future. A little maneuver around the event horizon for like 5-6 minutes will account for aprox. 100-150 earth yrs. Thus, someone can go past centuries without actually living it i.e. into the future. Also the maneuver is above the horizon so the risk of falling into the black hole is under control.

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.
