Does Time Really Exist....?????

Time is certainly a very complex topic in physics, but there is no real doubt among physicists that time does really, truly exist ... they're just divided a bit on what causes this existence.

The Arrow of Time and Entropy

The phrase "the arrow of time" was coined in 1927 by Sir Arthur Eddington and popularized in his 1928 book The Nature of the Physical World. Basically, the arrow of time is the idea that time flows in only one direction, as opposed to dimensions of space which have no preferred orientation. Eddington makes three specific points in regards to the arrow of time:

A. It is vividly recognized by consciousness.
B. It is equally insisted on by our reasoning faculty, which tells us that a reversal of the arrow would render the external world nonsensical.
C. It makes no appearance in physical science except in the study of organisation of a number of individuals.


The first two points are certainly interesting, but it's the third point that captures the physics of time's arrow. The distinguishing factor of the arrow of time is that it points in the direction of increasing entropy, per the Second Law of Thermodynamics. Things in our universe decay as a course of natural, time-based processes ,but they do not spontaneously regain order without a lot of work.

There's a deeper level to what Eddington says in point three, however, and that is that "It makes no appearance in physical science except..." What does that mean? Time is all over the place in physics!

While this is certainly true, the curious thing is that the laws of physics are "time reversible" ... which is to say that the laws themselves look as if they would work perfectly well if the universe were played in reverse. From a physics standpoint, there's no real reason why the arrow of time should by necessity be moving forward.

Catch A Lion With The Laws Of Physics (lol)

How to catch the lion DIFFERENT THEORIES.

1. Newton's Method:
Let, the lion catch you. For every action there is
equal and opposite reaction.Implies you caught lion

2. Einstein Method:
Run in the direction opposite to that of the
lion.Due to higher relative velocity, the lion will
also run faster and will get
tired soon. Now you can trap it easily.

3. Schrodinger Method:
At any given moment, there is a positive probability
that lion to be in the cage. So set the trap, sit
down and wait.

4. Inverse Transformation Method:
We place a spherical cage in the forest and enter
it.Perform an inverse transformation with respect to
lion. Lion is in and we are out.

5. Thermodynamic Procedure:
We construct a semi-permeable membrane which allows
everything to pass it except lions. Then sweep the
entire forest with it.

6. Integration Differential Method:
Integrate the forest over the entire area. The lion
is some where in the result. So differentiate the
result PARTIALLY w.r.t lion to trace out the lion

Apple Changed The Life Of Sir Newton

Sir Isaac Newton (1642-1727) is one of the few most influential scientists who ever lived. We know these names familiar from his theory of gravity, although gravity is not the only Newton's monumental discoveries. Newton was also bequeathed to us the concept of the light spectrum. He also noted as the inventor of the telescope reflection. Similarly, the law of motion which can explain many things about the orbits of celestial bodies, including our earth.

The birth of the law of gravity does have many versions. Some believe that the idea of gravity came after an apple fell on his head. Another version states that the source of the idea of ​​just when he saw the moon that hangs in the sky. In his biography instead told that the idea about the theory of gravitation was born after she remembered a childhood game: A bucket full of water tight rotated in a vertical axis so that the water in the bucket does not overflow even if the position of the bucket upside down.

Today, more than three hundred years after Newton formulated his theories, his findings are still relevant. During his life, Newton probably never imagined that the launching of rockets and interplanetary travel can now be done based on the formula which he discovered. Is not the concept of a spectrum of light used to measure the shift of the star is the fruit of Newton's discovery? The law of gravity to explain how a planet orbiting its parent star can affect. And do not forget the laws of motion which describes the period, mass, and distance of objects around a star. All that is born of the genius of Newton's brain three and a half centuries ago!

Incidence of apple fall inspired Newton to discover the laws that became known as the "Law of Style Weight (Gravity) Newton (1687)". It appears that, with the help of Newton's Law of Style Weight this, we begin to understand the origin of the cause of the fall of the apple in the earth's surface. And thus revealing clearly what causes attraction of apple fruit (by weight of Newton's Law of Force) and why it should fall to the surface of the earth (via Newton's Law of Motion).

Newton discovered the force of law formulation weight through an inspiration that came suddenly. Apparently not! Newton's theory of birth through a long process which was opened by the ideas of Copernicus, was pioneered by a pile of data Tycho Brahe, and who later worked on by Kepler. Newton's own discovery efforts with diligence be obtained through a time-consuming for scientists to understand the third. In fact, in 1666 he still does not understand it. Assumption about gravity saved by Newton for itself for decades.

Apple fruit itself is not anything. It just a twin of the full moon puzzle. Apples fall to earth, so did the moon come out from the straight path, around the earth. Apple and the moon is a coincidence.

In the study in his garden, and in contemplation of a self without stopping, and his reason are always filled with geometry modes and a new analysis, Newton makes the relationships between various domains of thought that are far apart. However, he was still not convinced. Calculations are still doubtful, he could only find the answers approach. He sought precision rarely found, beyond the ones permitted by the existing supporting data at that time.
