Space-Time

====

At the beginning of universe as per big bang model the universe had zero size. It is called as singularity situation. It means the universe was Infinitesimally small and indefinite dense. Under this conditions all the laws of science, and all ability to predict the future wud break down. Therefore if there were events earlier than tis time they cud not affect wot happens at the present time because it wud hv no observational consequence. It can be said the time started with the big bang. There is no single concept of time so it is called as time space. When space is created time is created.

I shall try you with this video later on but first let us try by Maxwell. It is a riddle. In space-time you must be aware of the fact that if a pulse of light is emitted at a particular time at a particular point in space then as time goes on it shall spread out as a sphere of light whose size and position are independent of the speed of the source. So let's we assume the entire light space is ‘P’. Ok?

Now we know the event shall cause three-dimensional cone in the four dimensional space-time of the event. So the cones have past light cone and future light cone. Therefore, if one knows what is happening at some particular time everywhere in the region of space that lies within the past light cone of ‘p’ one can predict what will happen at p. Then why shall we not understand the future?

Me Sir Waker Lewis it is always my pleasure.. Mr. Atheist your riddle cannot be well understood by all so before going to answer you I can try to simplify it.

The light cones as you have described can be well understood by an example. Suppose if we throw a stone on the surface of a pond. There ll be ripples after the stone is thrown. The ripples will keep spreading out as a circle and ll get big to bigger as time goes on. The spot at the surface of the pond the stone did hit is the event. The very moment the stone has stricken a point of the pond the space is created as ripples and the time started. Now right after the hit, created ripples is past cone and the last stage of the circle is the future cone. The entire circles are assumed as,”P”. My bro asked me if the event where the stone stuck is possible to calculate then the future, formation of the circle of ripples could be predicted. By that, he meant we could predict the future. The ripples are light or time and the circle is space. ………………..

We cannot understand the future from the same equation even by further study. In this equation of time and space, nothing can be understood outside the, “P” periphery. Where there is light, there is the calculation of time and event where there is no light there is no calculation because nothing can travel faster than light. If now the sun ceases to shine, we shall not know it.

…………………… We shall only know it after eight minutes. The past cone of sun is the future cone of the earth. We shall never be able to know the event of sun before eight minutes. Similarly we shall never be able to know wot s happening at the moment farther away from us in the galaxies we have seen, the light left us some seven thousand millions ago. Lol Actually when we see the stars we are not seeing the present event of the stars. We are seeing it as it was may be some 5 millions year ago and the light took the time to travel across the universe and reached today on the face of the earth. ………………… Moreover, Bro though it is not possible to describe in details but presently we cannot ignore gravitational effects. Once it was thought space and time is independent but it is not so. Now it is dynamic quantities. When a body moves or a force acts, it affects the curvature of space-time and in return the structure of space-time affects the way in which bodies move and forces act. Therefore, space and time not only affect any event but also are affected.

…………… It was Laplace who suggested that, there shud be some set of laws that can predict everything that ll happen n the universe. Well it was possible if we knew the complete state of the universe at one time. …………..

If we knew the positions and speeds of the sun and the planets at one time then we cud use Newtonian laws to calculate the solar system at any other time. …………………

In order to predict the future position one has to be able to measure its present position and velocity accurately. The accurate way to do tis to shine light on the particle. When these particles will be shined by light some of the lights will be scattered by the particles and tis ll indicate its location.lol as we do in x-ray our body.

The accurate way to throw light is shortwave. No one can throw arbitrary amount of light but must throw at least one quantum. Lol now when u shall throw the shorter wavelength it ll changes the velocity of the particle you are trying to locate. Shorter the wavelength means higher the energy of a quantum. Right? So wot is happening? …………………… The more accurately u r trying to measure the position of the particle the less accurately u can measure its speed, lol and vice versa. Yes, I am talking about Plank’s constant of Heisenberg’s uncertainty principle. We as the student of science know this uncertainty principle is an inescapable property of the world. . ………. We can never be able to have a standard unique coordinate to measure. ……….. Let me give you an example. We know this universe is expanding and we know no matter can travel faster than light. Suppose you are sitting in a railway platform by facing at the rail road, a train is heading towards the rail station and it ll not stop at the station but ll pass away it slowly for another destination.

Two men sitting inside the compartment of the train by facing each other. One among them is dropping a tennis ball on the same spot of the floor inside the compartment. The other person sitting face to face is observing the ball is dropping on the same spot ( Take this spot as an unique coordinate for the two passengers cuz they r observing the same spot) now when the train ll be passing by ,you shall observe that the ball inside the compartment has dropped just in front of you once and the second drop was little away from you , the distance of the dropping spot for you ll depend on the speed of the train.

So their coordinate and your coordinate for the event of the tennis ball r not the same. It shall never be the same thus none of us can accurately determine measurement tools of any event in this universe . ….. Therefore we donot hv any option in our hand to measure the event of this universe accurately by staying inside the universe.

…. Time and space is created simultaneously.If there is no time there is no space. ….. Behind the universe it was the singularity. In that stage there is no time and space, no past, present or future. The way we envisage yesterday ,today, tomorrow is not there in singularity infinity. ……… If there is no today and tomorrow then there is no beginning and ending. There is no time to pass or use, no space to let your body rest on a bed. No mug for you to drink , no shape, no color nothing. No physical presence as we are accustomed with is possible in infinity. …. Now being a Muslim I have no problem to understand this science. We are basically a wish of Allah. We live as a sprite or soul. In this physical world we have two entities but it doesnot mean we must hv these two attributes hereafter. On the other hand Quran itself said there are so many verses in the Quran are allegorical, metaphors. Regarding, “Hur” Islam says no eyes have ever seen and no mind can ever contemplate. It is revealing the rewards in the heaven ll not be any material thingy. …. We had been thrown into a big puzzle wot is called as universe where Allah created many things and we will again be taken out of this realm and ll be attached in the infinity as once we were.
