Time travel through black hole

Well what a black hole means.No one can properly tell what a black hole is? but it is consider as a heavenly body having infinite density and gravity from which the light also cant escape.what a time travels indicate then it indicates the movement of us in according to the time that is we can move to the past or future.It is the burning curiosity of the today's world on how do we move according to the time so the main focus here is we all may know that the time moves slow when the gravity is high, higher the gravity less is the time taken to make one rotation. So different planets have different times. In one place there is high gravity while in other place there is less gravity that affects the time period hugely.this is the region for the difference in time between different planets.
       
        It is also said that time in the near area of pyramid is also slow.Lets us consider a huge body of infinite gravity which is also called as black hole that has infinite gravity then how could we travel to it. Actually we are not going to travel to its centre but we are trying to travel to its outer orbit to where it has minor effect of gravity. From here we can launch a space ship which is very powerful and could overcome the minor effect of gravity. From rounding around the black holes orbit a person inside the space ship could feel that he is time travelling. In this way we can time travel through the black hole.

        But the nearest black hole is very far. The light takes 1600 years to reach to that place by its speed. we know that nothing could exceed the speed of light then how could we go there the first question rises that has no answer, and though it is considered true for the time travelled there are many limitations which need to be fulfilled and the next is the black hole is a huge mass and that having a huge diameter to where the spaceships takes much more time and finally there is a very high risk if that body reaches to the centre of the black hole. Then the body will never returns back so if the science of future find all these answers then to that time there we can have the time travel but till this time it is only in theory to time travel through black hole.

         Hence though the time travel is not possible through black hole but we can travel through "Worm hole" which the scientist have claimed to have existence in our universe this holes are the point that joins the portion of the universe i.e it joins the two points of time so if we can know about this hole then we can know about the time travel and the scientist are also searching  about this.

           The Hawking's theory has defined the time travel by the train to move round and round the earth it gives the explanation about the time difference or time dilation according to the light of speed but it is only in hypothesis as i have already mentioned that nothing could move with the speed of light.so this portion or idea of time travel is also do not work.

The science behind earthquake

There are a numerous plates of rocks on the earth's surface. When one rock plates slips on the another plate then the vibrations takes place and we called it as earthquake.The surface on where the plates slip to each other is called fault plane.The location below the earths surface from where the earthquake starts is called the hypocenter and the location directly above the surface of earth is called epicentre.
       
       We all have a common question why this happens well  inner core,outer core,crust,and mantle are the four layers covering the earth.The crust and the top of the mantle are arranged in like head and tail and they make the layers of the earth. If we watched all this pieces carefully then we observe many small pieces moving slowly here and there collidimg and slipping with one another.This small pieces are called as techtonic plates that forms the whole layers of the earth.The edges of this plates are very rough.  When the plates begin to move from one plates to another by passing they got stuck onto the surface and certain energy is stored on them and the energy is continuosly released by the plates unstick and a seismic waves radiates through the surface of the earth and this causes the vibrations of earth.The instruments used to record the earthquake is called siesmograph and their recording is known as seismogram

              According to the different mythology have different reasons for the causes of the earthquake.According to ancient greece,the god of the sea,poseidon have caused the earthquake.According to this mythology when the god became angry he would strike the ground with his trident and this causes the earthquake so the god was given the nickname as the "earth shaker".Similarly according to hindu mythology the earth is held by eight big elephant which is balanced on the back of turtle and that turtle is also put on the coil of snakes.If there is imbalance between them the earthquake comes. According to the japanese mythology a giant catfish called namazu causes earthquake. Hence in this todays  era all this things are outdated as we have got enough scientific proof to prove this.

     

               Similarly many of us too have a question of how true it is that weather and animals can predict the earthquake well in most of the cases they are true but are also false in some cases so the scientist couldn't recognize how do they predict this things and  how do they show this things similarly they show certain behaviour change before a few minutes or seconds how to they change have  remained  mysterious and dark side.

         Many people in the world lose their lives due to this disaster the highest magnitude of earthquake recorded was in southern Chile valdivia in 1960 and it had the magnitude of 9.5 according to the U.S geological survey. Indonesia has more earthquake than that of other countries.

History of origin of earth and modern man

The earth was originated 4600 millions years ago.The sun and the stars were formed from the spherical mass of dust and gases by slow condensation. The earth was one of the part of the sun but as the sun begin to spin quickly as due to its large mass the solar planets disattach from it.It contains many patches and ditches which was fullfilled by the rainwater to form seas oceans etc.The atmosphere at that time was called "reducing atmosphere" as the free oxygen was not found in the volcanic substance so as to prevent the formation of corresponding oxide.The atmosphere at that time was not suitable for the survival or growth of organisms but later on miller and urey experiment proved the possiblility of the survival of the organisms by passing different types energy for multiplying the condition of primitive earth to form oxgenated atmosphere that make the survival of the living organisms.The various elements on the earth settle on the different layers of the earth the heavier elemets like iron,nickel,silicon etc form the central core similarly medium weight elements like aluminium,silicon etc form the middle layer and finally lighter elements like hydrogen,helium,carbon etc constituted the early atmosphere.
        Hence in this way the earth and the atmosphere were formed and due condensation evaporation multiplication etc processes todays atmosphere is formed.

                   Before evolving to todays modern man the primitive age has a great history and it also a very interesting subject to read by the proof and definition of science.Due to many evidenses the scientist are able to predict the time of evolution of modern man.The modern man evolve today has come from the first predicted ancestors primates at 65 millions years ago , then comes prosimians about 60 million years ago.it comes at the eochene epoch.The new world monkeys evolve from the primate line about 50 millions years ago and there comes the intermediate between new world monkey and old world monkeys is called anthropoids which is the ancestors of monkeys , apes, and man.Similarly old world monkeys evolve about 25-30 millions years ago.Then comes the hominids that is considered the ancestors of apes, and man only. Then a main branch goes as it distributes chimpanzees, gorillas,orangutan,gibbons.thethis are collectively called as apex not only this but also then the distribution of slightly developed organism come and in this category cames ramapithecus about 14 millions years ago.,then it evolved to become australopithecus which evolve about 5 million years ago.then the homo habilis comes which evolve about 2 millions years ago. Then comes homo erectus 1.5 millions years ago.Similarly neanderthal man comes which is 70000to40000 years ago. Then come the cragnon man about 34000 years ago and finally a man comes about 10000 years ago .In this way we the todays man are developed.but in the past before our evolve ment there were many hypothesis and wrong concept about the evolution of man due to lack of reasons and proof but due to continuous work of scientist on this field we are able to predict the date and evolution of different forms of life from evolution till todays time.The people in the ancient age were very conservative and belongs to the religion preserver and at that time Darwin suggested that the man evolved from ape like ancestors but it was not a wrong concept that man is evolved from monkey at that time this concept was steongly criticized by metaphysical and religious circle.At that time there were not good and developed technology that we have today and less data were available the apes are very specialized today and also the human beings are.
   
         So in this way the modern human beings are evolved from the different mode of evolution.

Why do we dream science explanation

When we fall asleep we all have some dreams.well so whats the definition about dreams then? According to Wikipedia"Dream are the things which we see involutarily see when we are fall asleep that may represent images,ideas and our thought".so the question arise do we all have dream so the answer is yes .We all people have some dreams.If we all have dream then what a blind people see if they are blind from their child.So if they are blind then there is complete darkness in his dreams but due to the sense of hear , touch and other sensations they dreams .We cannot remember all the dreams most of the dreams which we see at night we forget all that dreams and only a few portion are remembered .Why do we have dream the science cant explain why we dream and what the science behind dream.Though some psychyatrist and scientist can explain about it in their own.
According to sigmund freud a well known psychologist has explained it in his way according to him in our day to day life we have many things that come to our mind some of the things we can express while some cant due to our society taboos and restrictions and when that things come up in our mind and stimulate us now they become a burning desire and to full fill it dream comes if some one has a burning desire to buy a car then he sees it in his dreams because during sleep the brain is relaxed and no any intelligence and supression come before it.We are fully relaxed and now our mind will shows us the dream which we have imagine.Just like in teen agers the dream which the youths see is wet dreams why this occur then because teen ager is a transition period of child to youth and a great harmonal change takes place during this period due which there is a strong attraction force between opposite sex and they cant full fill their desire to have physical relation as due to restriction and taboos of the society,so they have wet dream.

The people also has the mentality that the dreams serve as intermediate between the future and the presents.People predict the future of the people by the dreams they see at night during sleep.In dream where we can know that we are having dream then such dream is called "Lucidity dream".Some of the mythology also confined it as a event that occur before our birth in previous life but this is not possible in terms of science as science is leaping only because of proof and reasons but there is not such real proof so it is not given much preference.Dream also changes from person to person on the basic of nature and habits of people their attitude and ages due to which the dream varies from person to person.

However all those facts also if we take a deep and serious look at the dream then we will find a surprising and amazing but reality which has no appropriate reasons to describe and its occurence is also mysterious in todays time .Which we always see but do not notice but at last dreams are dreams having some connection with our lives but that do not carry any negative sign because it depends on our ways of visualizing and thinking

History of atomic discovery

Many people for a centuries believed that the substance were formed from the few basic elements.Different religions have described different elements which is the block of nature.It has described basic elements but no one in ancient philosophies coincide with the concept of atoms but it was only in the 5 th century, when a scientist named Leucippus wondered what would happen when we break a piece of particles to its smallest one and he also tried it experimentally and broke the particles to its smallest one until it become invisible so he coined the term atom  meaning "unsplittable ".

  Moving on further investigations and discoveries went on the path of atoms different scientist gave different opinions on the basic of reasons or hypothesis.Democritus,studnet of leucippus worked on his idea and theory and stated that the human mind as well as a huge space between the atoms and all things ate made up of atoms which was explained without proof by only reasoning in favour of law of nature.

  Jojh dalton  later on investigate and discovered properties of atoms and posted a postulates about atomic theory people at that time gave preference to his theory but as it has too many limitations it was broke out in today's date .
The postulates of daltons atomic theory are
 *atoms are the smallest , invisible and indivisible parts of a matter.
*atoms of the same element are identical in all respect but different from those atoms of other elements
*atoms can neither be created nor can be destroyed
*atoms can combine in a simple whole number ratio to give a compoud atom.
   
        Though his postulates gives first all the concept of atom it is outdated as it has limitations so the limitaions of daltons atomic theory are
* Due to the presence of sub atomic particles like electron proton anti quarkete it is further divisible.
*Atoms of the same element may be different in some respects due to presence of isotopes.while atoms of different elements may be identical in some respect due to isobars.
*Atoms can neither be created nor can be destroyed but can be transfer from one form to other by nuclear reaction.
* Atoms can also combine in a complex whole number ratio to give a compound atom.
     
     Hence in this way we came to conclude all the natures and characteristics about atoms in this golden era of science from the continuos research from the back thousand years till now.


                      ONE MEMORABLE STORY
                              JOHN DALTON
When john dalton was asked why he never married ,he replied "I havent time.My head is too full of triangles, chemical processes and electrical experiments to think of any such nonsense."

What is lifi and its working

Light fidelity (lifi) is a latest technology that will replace wifi and makes the speed of internet much more faster than the wifi does. Its an important the name (lifi) was given by harold harras.It operates by visible light communication system.Its not a project but a reality that will make the world more small and globalized

It has claimed to reach the speed 100 times much faster that the wifi does.It brings solution about the wire or optical fibre.It reduces globally 60% traffic in internet by making it faster.Light is only medium that can be transferred easily and maximum velocity as no other things can move with the speed of light. It too has a frequency 1000 times more than magnetic waves it emmits the light through light emmitting deodies i.e LED as medium to flow network connection in the mobile or laptops in a similar way as the wifi does.This technology too has an advantage to overcome electromagnetic sensitive areas such as hospitals,airways cabbin and many other sensitive places as they do not interfer with the electromagnetic waves. It has the capacity to operate in that place.The first VLC (visible lighting communication was presented at the consumer electronic show in las vegas. It uses a wysips connect that converts light waves in visible energy without decoiding or sending its power in the battery. It is covered by a thin cover that is usally seen in watch or other smart gestures that is made solar power trapper.It is also have said to increase the battery life by15%.Philips a reputed company has put VLC into practice by making app that need to be download in playstore that will detect where is the location of the person and provide them a necessary imformation of all the things.

Lifi is a revolutionary trend that has revilolutionized the wifi, it is an it has tested in many companies and the result is really amazing 100 times faster than wifi. BMW car has also started selling the lifi headlights and also as we also have discuss that it is really cheaper as it doesnt go through the long processes as the wifi goes prof harold harass has also said that we can put the currently existing solar power panel in the roof that traps the light energy from the nearest station from which the panel can easily transmitt the signal and we can use it any time. Really it has the speed of 10gb per second speed which is amazing.

       So hope and pray for the future that lifi will succeed in meeting the expectations of the people so in this way the near future will be supported.

Eukaryotic cell without mitochondria

Eukaryotic cells are those cells having well developed nucleus.They are mostly present in well developed organisms.They possess all important cell organelles but a latest study has shown a slight different that changed the concept and attitude of the people well it the study had shown that the mitochondria is absent in a specific type of eukaryotic cell microbe that live in the guts of chinchilla. Mitochondria are the power house of the cell as they release energy in the form of STP or ATP.It is really amazing as well as surprising to hear that.Not only mitochondria releases energy but it also helps in the respiration so it fulfills it through anaerobic respiration it the cell is named as monocercomonoides .It also replaces many other fuction of mitochondria.It too helps in the assembly of iron and sulphur clusters.
