Time


Time is very variable "Element" of our life. It gets changed at every movement. It can be defined in different ways but still not clearly understood. 

Different Definitions of Time:

1. The indefinite continued progress of existence and events in the past, present and future, regarded as a whole.
2. A point of time as measured in hours and minutes past midnight or noon.
3. Time is part of the fundamental structure of the universe – a dimension independent of events, in which events occur in sequence.

There are many definitions available in religion, philosophy, and science. But the question is that: Can they define the Time?

“It was Einstein’s genius to realize that the speed of light is absolute, invariable and cannot be exceeded (and indeed that the speed of light is actually more fundamental than either time or space). In relativity, time is certainly an integral part of the very fabric of the universe and cannot exist apart from the universe, but, if the speed of light is invariable and absolute, Einstein realized, both space and time must be flexible and relative to accommodate this.” Hawking talks about time in Einstein's theory of relativity. One prediction that Einstein's theory makes is that time will go by slower when something is near huge masses. However, when something is farther away from the mass, time will go by faster. Hawking used the idea of two twins living at different places to describe his idea. If one of the twins went to live on a mountain, and another twin went to live near the sea, the twin who went to live on the mountain would be a little bit older than the twin who went to live at the sea.

Though this genius has explained the Time very precisely and accurately, can it be understandable of defined? Can we able to predict it? There are so many research done on this phenomenon to predict the Time and to try to control it. But none of them have ever been succeeded.

The only truth is that we can only measure the time which is passed in the terms of seconds, minutes, hours, days, weeks, months, years and so on… But we can never predict it. If we think that time is measurable and we can absolutely and invariably measure it, we may be wrong. Because time is relative phenomenon and it is relatively of different “size” for different species on the earth.

Humans have discovered the tools like clocks and calendars to measure the Time but do you really feel that this is the way by which time is accurately measured?
There are few species on the earth like microorganisms and other insects whose lives are of relatively very lesser than the animals and humans.

Same way if we compare the length of day on earth with the length of day on other planets, we can see the difference as follows:


Planet
Day in hours
Mercury
1,408 hours
Venus
5,832 hours
Earth
24 hours
Mars
25 hours
Jupiter
10 hours
Saturn
11 hours
Uranus
17 hours
Neptune
16 hours

Age of the Universe it predicted as 13.8 billion years, when the Big Bang took place and the “Time” originated with the motion of this Universe. It is proved that the Universe is continuously expanding with time and it may be end in the Black Holes. As we know the Black holes have the tremendous gravitational force which can control or seize the Time. So we can say that time is originated by the Big Bang and will end up in the Black Holes.
