Is universe expanding or contracting?

As its a fact after big bang our universe started to expand. But the question is upto what extent it would expand?</div>
<div dir="ltr" style="color: #222222; font-family: arial, sans-serif; font-size: small;">
There might be some limit. Then may be after that it would start to contract towards it centre. This can be the end of universe! If there is a beginning then there must be an end of it.</div>
<div dir="ltr" style="color: #222222; font-family: arial, sans-serif; font-size: small;">
This can also be the reason why we are seeing speedier separation of galaxies. Galaxies closer toward centre accelerating speedily towards centre.</div>
<div dir="ltr" style="color: #222222; font-family: arial, sans-serif; font-size: small;">
After big bang a force was exerted in outer direction and universe is said to expand. But then an equal force must have also been exerted in inward direction.<br />So the centre started to shrink down and became a great central mass or may be a universal black hole. It is attracting attracting other galaxies.</div>
<div dir="ltr" style="color: #222222; font-family: arial, sans-serif; font-size: small;">
There arises also a question why big bang occurred?<br />This all started from a zero after big bang, then what made this zero to bang and expand?<br />This question we all might think of many times but end up stressing myself with nothing.</div>

<span style="color: windowtext; font-family: "Times New Roman","serif"; font-size: 12.0pt; mso-bidi-font-weight: bold;">CAN stands for control area
network. This is a communication protocol in which more than one control
communicates with each other without a host PC in between them. In this the
target for each controller is defined but the task are interdependent that is
some input will be taken at one controller and the output will be generated by
the other controller likewise may more. This communication protocol finds
application in large industrial automation.<o:p></o:p></span></div>

security design uses the same communication protocol where there are three
microcontrollers each having its one specific task. The first control will be
interfaced with the keypad to check the password. The second controller will be
interface with buzzer and the gate opening circuit. The third controller will
be interfaced with the 16x2 LCD. If the password entered is correct there will
be no alarm and the gate will be opened with proper display of encrypted
password on the LCD and the notifications also else vice versa will happen.<o:p></o:p></span></div>

3 MCs as per the circuit shown, one for input, one for display and the other for

We are not using Read/Write (RW) Pin of the LCD, as we are only writing on the LCD so we have made it grounded permanently.

<div align="justify">
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;"><span style="color: black;">Cymatics,
 the study of wave phenomena, is a science pioneered by Swiss medical 
doctor and natural scientist, Hans Jenny (1904-1972). For 14 years he 
conducted experiments animating inert powders, pastes, and liquids into 
life-like, flowing forms, which mirrored patterns found throughout 
nature, art and architecture. What's more, all of these patterns were 
created using simple sine wave vibrations (pure tones) within the 
audible range. So what you see is a physical representation of 
vibration, or how sound manifests into form through the medium of 
various materials.<br />
                <br />
              </span><span style="color: black;">Dr.
 Jenny's methodology was meticulous, well doumented, and totally 
repeatable. His fascinating body of work offers profound insights into 
both the physical sciences and esoteric philosophies. It illustrates the
 very principles which inspired the ancient Greek philosophers 
Heraclitus, Pythagoras and Plato, on down to Giordano Bruno and Johannes
 Kepler, the fathers of modern astronomy. "In the beginning was the 
word..." takes on a whole new meaning while looking at these 
experiments!</span></span></span></div>

Fibonacci sequences appear in biological settings,<sup class="reference" id="cite_ref-S._Douady_and_Y._Couder_1996_255.E2.80.93274_8-1"><a href="http://en.wikipedia.org/wiki/Fibonacci_number#cite_note-S._Douady_and_Y._Couder_1996_255.E2.80.93274-8"></a></sup> in two consecutive Fibonacci numbers, such as branching in trees, arrangement of leaves on a stem, the fruitlets of a pineapple,<sup class="reference" id="cite_ref-Jones_2006_544_9-1"><a href="http://en.wikipedia.org/wiki/Fibonacci_number#cite_note-Jones_2006_544-9"></a></sup> the flowering of artichoke, an uncurling fern and the arrangement of a pine cone.<sup class="reference" id="cite_ref-A._Brousseau_1969_525.E2.80.93532_10-1"><a href="http://en.wikipedia.org/wiki/Fibonacci_number#cite_note-A._Brousseau_1969_525.E2.80.93532-10"></a></sup> In addition, numerous poorly substantiated claims of Fibonacci numbers or golden sections
 in nature are found in popular sources, e.g., relating to the breeding 
of rabbits in Fibonacci's own unrealistic example, the seeds on a 
sunflower, the spirals of shells, and the curve of waves.<sup class="reference" id="cite_ref-51"><a href="http://en.wikipedia.org/wiki/Fibonacci_number#cite_note-51"></a></sup></div>

Fibonacci numbers also appear in the description of the reproduction 
of a population of idealized honeybees, according to the following 
rules:</div>
<ul style="text-align: justify;">
<li style="text-align: justify;">  If an egg is laid by an unmated female, it hatches a  male or drone bee.</li>
<li>  If, however, an egg was fertilized by a male, it hatches a female.</li>
</ul>
<div style="text-align: justify;">
Thus, a male bee always has one parent, and a female bee has two.</div>
<div style="text-align: justify;">
If one traces the ancestry of any male bee (1 bee), he has 1 parent 
(1 bee), 2 grandparents, 3 great-grandparents, 5 
great-great-grandparents, and so on. This sequence of numbers of parents
 is the Fibonacci sequence. The number of ancestors at each level, <i>F</i><sub><i>n</i></sub>, is the number of female ancestors, which is <i>F</i><sub><i>n</i>−1</sub>, plus the number of male ancestors, which is <i>F</i><sub><i>n</i>−2</sub>.<sup class="reference" id="cite_ref-56"><a href="http://en.wikipedia.org/wiki/Fibonacci_number#cite_note-56"></a></sup> This is under the unrealistic assumption that the ancestors at each level are otherwise unrelated.</div>

The DNA molecule measures 34 angstroms long by 21 angstroms wide for 
each full cycle of its double helix spiral. 34 and 21, of course, are 
numbers in the Fibonacci series</div>

A mobile phone is something that was put together in an organized way, so it must have an organizer. In the same way, when we see the order in the universe, it is rational to say that the universe has an organizer.</div>
<div style="text-align: justify;">
This ‘organizer’ is  God. God is the one who bought about the order in the universe.</div>
