GRAVITARIONAL WAVE BY NEUTRON STAR

 

In total we have found 11 gravitational wave's but except fourth one all of them are produced by black hole's that fourth gravitational was recorded in 17 august 2017 which was produced due to collision between two  Neutron star this discovery started a new AGE in the field of Gravitational-wave astronomy . 

 

For researching on Gravitational wave a Hi-tech laboratory was  established and known as Laser Interferometer Gravitational-Wave Observatory (LIGO)  .  first evidence of gravitational waves was encountered in 14 September  2014 but it could be bogus that's because scientist's investigated that waves keenly and then they announced its existence , in 11 February 2016  very  first gravitational wave , and they named it "GW150914".

 

This first detection of gravitational waves was huge success for scientific society because then we started learning new language of cosmos scientist's  was then so confident about they can now know about something very far from there limit's , after first  gravitational waves till 17 August  2017 three more gravitational waves (GW151226,GW170104,GW170814) had been detected .

FOURTH GRAVITATIONAL WAVE 

Before recording fourth gravitational waves . satellite's detected X -Rays of it , and after there 2 second gravitational waves was detected at Earth , reaching at the same time and it has been proved that light and gravitational waves propagates at the same speed as predicted by Einstein in his General theory of relativity .

      INVESTIGATION 


This fourth gravitational waves was generated 1300 lakh light years away due collision of two neutron star , waves generated was related to kilonova , the blast happens due to emerging of two Neutron star is known as kilonova . it may be possible that after colliding it became BLACKHOLE but its not possible to say it surely , this gravitational waves are very special cause it related to neutron star . 

 

And in case of black Hole they do not let radiation to escape so very little information they emits . but kilonova emits to much radiation as well as messages encoded in diffrent form . this gave birth to multi-messenger astronomy .

       BIRTH PLACE OF PRECIOUS METALS

With discovery of fourth gravitational waves , observing the electromagnetic waves related to it had strong proofs of Kilonova is a birth place for precious heavy metal's . like gold , platinum . 

 

During kilonova huge amount of neutron is dispersed in surrounding and if already present iron nucleus absorbs neutron before disappearing of iron due to its radioactive nature it will start forming heavier nucleus atom , scientist's call this process as RAPID NEUTRON CAPTURE PROCESS .

CONCLUSION

Finally mystery of forming heavier nucleus than Fe has been solved , scientist's are very excited now they will start getting such information which they thought nature itself didn't want to share it with them . discovery of more terrestrial strange object's which was undetectable before will be possible now .

WHAT IS NANOTECHNOLOGY ?

N anotechnology is the science of manipulation of matter according to our need at the Nanoscale of the order of 10^-2 . it have tremendous possibilities in near future because of its ability of making advance material  with unique chemical property which suits according to condition   .  This term technically first time introduced by physicist Richard Feynman in 1959 in his lecture with topic of There is plenty of room at the bottom . but at that time technology was not enough to implementation of his idea in practical application's . Primarily there is two type of approaches we use to construct anything  - I)  Top-to-bottom approach  II) Bottom-to-top approach Top-to-bottom approach :- when we cutoff resource to make our desirable shape is known as Top-to-bottom approach ; Ex- wooden chair .  Bottom-to-top approach :- when we construct structure by starting from its minute cells to approaching required shape of structure is known...

CAN WE PRODUCE CLEAN ENERGY ?

World is full of advancement today from previous era , we have astounding facilities good lifestyle better food and more but did you ever feel amazed how all of this possible today which was impossible before , all of this happens because of our developed technology of converting energy from one form to another with increased efficiency . but we are again at the bank of river of question's  , question which is seducing me from past several months and its attempt to draw my attention is legal too because of our current condition  a problem of ENVIRONMENTAL POLLUTION who is grown up baby now of our human race and its age is from industrial revolution to today's date . if i play little maneuver to our problem of environmental pollution to a QUESTION as              " is there any way to get immense treasure of clean energy ? " like we usually do in mathematics , and if yes than how , here the clean energy source ...

NOTION OF TIME BEFORE ALBERT !

  I n ancient Greek philosophy one of the two philosopher who influenced entire western philosophy was Aristotle and Plato , Aristotle was student of Plato due to his extraordinary brilliance his master Plato said  " the mind of academy " in his respect .   A philosopher who gave his contribution nearly to every subject that exists in that era , according to  Aristotle .               " Time is nothing but measurement of change " A classical way of giving definition about something,lets again pay little attention to chosen word's here "time" a subject about which he gave his opinion  then "nothing but" this words makes sure it is only "measurement of change" or change in temporal world we live in . that means there will be no time if everything  around  us directly or indirectly frozen even our brain nerves are frozen so we cant even notice that nothing is changing .  in my opinion...
