Searching for our origin.The journey must go on!

Right from the early days of humanity , curiosity has been a key element in the development of mankind. Either this curiosity is induced in it or it developed on its own is also a question of debate like the existence of mankind itself. Probably the most appealing question for human curiosity is the creation of this universe and what brought us to the point of existence.

If we see the endeavors by humanity, from the invention of wheel and use of fire to landing on moon and aiming to discover the farthest places of the universe , we see the purpose of life as exploring things to satisfy the hunger for knowledge and to discover the unknown.

TIME

If I say, “I know something that has already happened in the future.” then you may think I am wrong but many philosophers and physicists believe the possibility of such statement being true.

Present, past and future are relative terminologies used with the events occurring in a particular time. Then question arises what is time? This is one of the burning questions with many contradictory answers.

“A successful unification of quantum theory and relativity would necessarily be a theory of the universe as a whole. It would tell us, as Aristotle and Newton did before, what space and time are, what the cosmos is, what things are made of, and what kind of laws those things obey. Such a theory will bring about a radical shift – a revolution – in our und2erstanding of what nature is. It must also have wide repercussions, and will likely bring about, or contribute to, a shift in our understanding of ourselves and our relationship to the rest of the universe” (Lee Smolin)

Physicists define time as what the clock reads. But this is not simple as it looks, this statement it self opens another series of confusing questions like what is the starting point of time? Does time has a start? Is time finite? Is time always real?

Many of the scientists consider time has roots leading to the Big Bang. But on the other hand another argument waits what was Big Bang and also whether there was any Big Bang ?
Time is also considered to be relative with respect to space that’s why we use the term space time coordinate. This can be understood by a simple example:

If I say a point was on x=0, y=0 and z=0 position at t=0 time and then moved to x=1,y=2 and z=2 at t=1 time means in 1 unit of time the point moved 3 position units (using difference formula).

Another question arises is the time same or the clock same for every observer? Einstein’s special theory of relativity did away with the idea that events can be simultaneous if they are in different locations. The difference in time between two events depends on their difference in distance and how fast the observer is moving.

Time is considered by some as linear such as Newton and Bacon who considered time as one way with no coming back but in the twentieth century, Gödel and others discovered solutions to the equations of Einstein’s general theory of relativity that allowed closed loops of proper time. These causal loops or closed curves in space-time allow you to go forward continuously in time until you arrive back into your past. Which means we can go to our past meet our childhood self. On the other hand time dilation concept allows you to see the future.

There are other terminologies we use which are related to time such as duration, occurrence of events, instants. Events occur in a particular duration of time. Time is also defined as the collection of instants and instants are said to be the boundaries of durations. Durations are considered to be an ordered set of instants means instants are not part of duration but a member of duration.

Now at the end of my article I quote Albert Einstein who once said, “The development during the present century is characterized by two theoretical systems essentially independent of each other: the theory of relativity and the quantum theory. The two systems do not directly contradict each other; but they seem little adapted to fusion into one unified theory. For the time being we have to admit that we do not possess any general theoretical basis for physics which can be regarded as its logical foundation.If it is true that the axiomatic basis of theoretical physics cannot be extracted from experience but must be freely invented, can we ever hope to find the right way? I answer without hesitation that there is, in my opinion, a right way, and that we are capable of finding it. I hold it true that pure thought can grasp reality, as the ancients dreamed.”

I hope we will be able to find the right way.

Origin of the Universe(Part 3)…Kun Faya Kun

Filed under: exploration, physics, thoughts — Tags: , , , , , , — syedfaisal @ 6:08 pm

originofuniverse

Though I am in the process of searching for the answer and during the last few days i was thinking on the same old question of origin of the universe (i leave the details for some future post of the series) and that search came up with new sets of questions to answer when I started to look into the words of the Quran ,”Kun Faya Kun”(Be and it is) with a slight different point of view.

Uptill now most of the creationists and evolutionists debates go around the issue whether God created the universe or it happened by chance and then a series of

events happened resulting in the triggering of other events

leading to the

creation of the universe in the current form which is still expanding

means the process is continued.

Research is being going on to discover the initial conditions of the universe so as to complete the scientific

model of the universe based on mathematical proofs

but still after years of research we are

still in the initial stages

(I am saying this because a lot is yet to be discovered).

Remarkable achievements have been made such as development of the detailed map of the universe by scientists with the help of the United Kingdom Infra-Red Telescope(University of Nottingham worked on the project for three years and announced the results recently) and on the other hand some people consider it

a waste of time to think on the topic and say God has made it so it  is

but the problem is how?

and what was the mechanism?

Was the process self triggered or someone was required

to initiate the process?

Was and is the process self running or someone is needed to run it?

After giving some time thinking on the words Kun Faya Kun (Be and it is), it seems to me quiet religious to

think of the origin process as self  triggered and self running (don’t think I am an evolutionist , I am still searching for the answer) because be and it is means the process of origination initiated by itself and so the continuation of the process is still there even today .

Could The Universe Be Tied Up With Cosmic String?—>An remarkable discovery in pursuit of the very origin of the universe.

Filed under: exploration, physics — Tags: , — syedfaisal @ 5:38 pm

An interesting discovery related to the very origin of the universe.

It Says: “A team of physicists and astronomers from the University of Sussex and Imperial College London have uncovered hints that there may be cosmic strings – lines of pure mass-energy – stretching across the entire Universe.” The details (from sciencedaily.com) are:

Cosmic strings are predicted by high energy physics theories, including superstring theory. This is based on the idea that particles are not just little points, but tiny vibrating bits of string Cosmic strings are predicted to have extraordinary amounts of mass – perhaps as much as the mass of the Sun – packed into each metre of a tube whose width is less a billion billionth of the size of an atom.Lead researcher Dr Mark Hindmarsh, Reader in Physics at the University of Sussex, said: “This is an exciting result for physicists. Cosmic strings are relics of the very early Universe and signposts that would help construct a theory of all forces and particles.”His team took data from NASA’s Wilkinson Microwave Anisotropy Probe (WMAP), which is a satellite currently mapping the intensity of cosmic microwaves from all directions, and carefully compared the predictions of what should be seen with and without strings.Dr Hindmarsh said: “We cannot yet see these strings directly. They are many billion light years away. We can only look for indirect evidence of their existence through precision measurements of the cosmic microwave background, of cosmic rays, gravitational radiation, and looking for double images of distant quasars.”The four-person team are members of COSMOS, the UK’s world-leading cosmology supercomputing consortium fronted by Stephen Hawking. Using a Silicon Graphics supercomputer they made predictions of how the strings would affect the Cosmic Microwave Background, relic radio waves from the Big Bang which fill the universe. It turned out that the best explanation for the pattern of this radiation was a theory which included strings.Dr Hindmarsh said that better data is required before the existence of cosmic strings can be confirmed. He hopes this will be produced by the European Space Agency’s Planck Satellite mission (due for launch this year).The results are published in Physical Review Letters on 18 January, 2008.
