WHAT IS TIME?

TIMEAn indefinite and continuous duration regarded as that in which events succeed one another.

The present is the conscious-ness or awareness of recording of memory into the brain. Im-agine two objects, one mov-

ing in orbit around the other, in space. Now suppose from our distant observation point of a fixed time, we observe time

to get slower in the area where these two objects are moving.

We expect to see slower mo-tion? We also should observe

proportionally weaker gravi-tational force; otherwise the

objects will get pulled togeth-er. If we observed faster time,

we expect to see faster motion and stronger gravity to keep

the objects from flying apart. While with zero time, motion

will freeze and gravity will become zero.

The increase or decrease in strength of gravity is only in relation to our fixed time from where we are making the observation. From the point of view (time) of the orbiting objects neither mo-tion nor gravity has changed.

As this thought experiment also can be extended to par-ticles held together by elec-tromagnetic forces we can say that time involves both mo-tion and forces. Time involves all kinds of motion. The spin of particles and the motion of photons are dependent on time. Gravitational force and electromagnetic forces are all part of time as well, as is the motion of celestial bodies the atoms and all other motion.

DO WE FULLY UNDERSTAND TIME?

CAN TIME BECOME OBSELETE?

The Speed of Light

The Earth’s Rotation

In an article of the magazine Scientific Amer-ican, Craig Callender compared time with

motion. Time is a way to compare or describe different kinds of motions like speed of light, how fast heart beats or how frequently earth

spins around its axis. But these processes could be compared directly without making reference to time. These graphs illustrate the

difference between using seconds and heart-beats to measure the speed of light and the

Earth’s rotation.

Time may just be a common unit of motion against which all other motions are meas-ured, making the world easier to explain but having no independent existences from these other motions. This suggests the underlying mechanism that time is just the presence of motion. If someone would think about how different the world would be if we were to use these different measurements, they may be surprised at how miniscule the existing difference actually is.

Entropy is a term usually associated with ther-modynamics, but can also be used in con-junction with time. Entropy is common-ly associated with the amount of order, disorder and/ or chaos in a given system; the higher the entropy, the greater the disorder.

This disorder usually refers to the number of dif-ferent microscopic states a system can be in (the exact states of all of the molecules making up the system). The idea here is that even knowing the composition of a space (volume, energy pres-sure and temperature) doesn’t tell us much about the exact state of each molecule in the system.

Due to the fact that we cannot see what state a system is in, people often like to say that entropy is a descriptive measure of how uncertain or ignorant one is about the ex-act, detailed, microscopic state of a system.

As an example, suppose that you put a mar-ble in a large box, and shook the box around, and you didn’t look inside afterwards. The marble could be anywhere in the box, so the marble in the box has a high entropy.

Now suppose you put the marble in a tiny box and shook up the box. Now, even though you shook the box, you pretty much know where the mar-ble is, because the box is small. In this case we say that the marble in the box has low entropy.

CONSIDER A SOLID OBJECT...

COMPOSED OF MILLIONS OF MOL-ECULES AND ATOMS HELD TIGHTLY TOGETHER AND HIGHLY ORDERED

. . .IF A PART OF THIS OBJECT IS DESTROYED ON A MOLECULAR LEVEL, THE SPACE THE OBJECT OCCUPIED WOULD BE MUCH EMP-

TIER AND SIMPLER...

BUT THE MOLECULES WOULD BE IN COMPLETE DISARRAY

IS A LIFESPAN A BILLION HEARTBEATS?

So the length of a lifetime... 1 billion heartbeats. Not a human life alone,

apparently the lifespan of all am-phibians, birds, fish, mammals and reptiles can be counted in number of heartbeats, and that number is

about 1 billion.

How can that be? I will explain it to you, Humans live in average 65 years, hamsters in average 3 years and Artic whales as many as 150 years, but the number of heartbeats stay the same.

Because whales can have as few as 10 heartbeats a minute and hamsters as many as 450, during a lifespan the

number of beats averages, still, at about 1 billion.

At the rate of 70 beats per minute, hu-mans shouldn’t be living past young adulthood, and that what true for most of our history and is still the case for many parts of the world, with life spans between 33 and 35 years.

Developments in health treatments and sanitation have expended that to about twice as much, but the natural connection remains intact. These measurements started in the 1930s, work of Swiss-born chemist Max Kleiber. The Kleiber Ratio de-termines that for every creature, the amount of energy burned per unit of weight is proportional to that animals mass to the three-quarters power.

It is my feeling that Time ripens all things; with Time all things are revealed; Time is the father of truth.
