A Bouquet of God’s Beauties


A piece from Harun Yahya.
Please kindly read, enjoy, and absorb!


A Bouquet of God’s Beauties

All the living things on Earth have been created with innumerable, exceptional and superior features, from reproduction to defense, and from the way they feed to their systems of movement. Some build nests like architects, some ponder like chemists and come up with the ideal form of heating, and others still are true masters of camouflage. When one examines the lives of these creatures they will see that both the physical attributes and behavior are in complete harmony with one another and with their environment.

You can see a few of the extraordinary features possessed by living things.


Whale
The whale, the largest mammal in the sea, is at the same time the largest creature on Earth. Even some dinosaurs, which lived and became extinct millions of years ago, are dwarfed by whales. The blue whale in particular is considered to be even larger than all the dinosaurs known to date. Blue whales have a tongue the size of an average sized elephant and a heart weighing 900 kilos.

A heart, the size of a small car, pumps 10 tons of blood a second. Yet the food that such a giant creature consumes is quite astonishing. Blue whales feed solely on prawns, just a few centimeters long. The whale has to consume around two tons of prawns a day to completely fill its stomach.

Blue whales are not solely noteworthy for their size, however. They also possess complex bodily systems. The surface of the water is warm, but the deeper regions of the seas are cold. This means that there is a large temperature difference between the surface and the sea bed. Yet whales are unaffected by this since their fins function like air conditioning units. As the whales, created by God with such a superior feature, dive to the bottom they cool their bodies with their fins, and warm them again while rising.

The Clever Survivors from the Pole of Earth

Emperor Penguins
Emperor penguins are able to dive to depths of 500 meters (1,640 feet) for up to 20 minutes with no adverse effects to their respiration or blood pressure. They also possess the ability to adapt to these conditions in different ways. While diving, they are able to lower their heartbeats from 200 a minute to only 60, thus allowing them to store extra myoglobin.

How Can Penguins Hold Their Breath for So Long?
Myoglobin is a protein present at high levels in these birds’ muscles. These myoglobin proteins bind to themselves high numbers of oxygen molecules. In other words, the penguin conserves the oxygen it will need not in the air held in its lungs, but directly inside its muscles.  This lets penguins swim underwater for long periods and to dive as deep as they wish, without relying on the breathed-in air held in their lungs..

Why Do They Not Suffer from the Bends?
Penguins are able to continue swimming even when the oxygen in their blood drops to the lowest levels. Human beings suffer from the bends under such conditions. The level in question is 20 mm Hg for penguins and 25 mm Hg for humans. However, scientists have been unable to explain how penguins can to overcome this in the water without being affected by low levels of oxygen in the blood.

How Can They Go Without Food for 65 Days?
Male penguins have a secret that lets them survive without eating anything for 65 days, until the females arrive to take of the young in order to protect their eggs: they possess a structure capable of blocking their digestive systems..


Their Magnificent Diving Costumes
Adult penguins on the ice eat nothing for months until after they shedd their coats in the summer. All their old feathers are shed, and new ones emerge from underneath. The result is a windproof, insulated and waterproof diving suit that prevents  cold—whether from icy wind or frigid water— reaching their skin. The most striking feature of  their new plumage is that it appears just when the penguins need it most— when the time to migrate has arrived.

Brief Facts from the Pole
In the middle of winter, daylight at the North Pole last for only three hours. In order to protect themselves from the freezing cold during the other 21 hours, penguins huddle up against one another in the dark.

By huddling up to one another, the male penguins are able to raise their body temperatures to up to 20° C (68° F).

The World of Miracles


Have a look around you from where you are sitting. You will see that everything in the room has been “made.” All the countless details, such as the walls, the furnishings, the lamp, the chair you are sitting in, the glass on the table, the carpet… None of them came into being by itself, and neither did the universe that we live in.

Everything, every tiny detail, from the atomic, the smallest component of matter, to the galaxies containing billions of stars, from the Moon, the inseparable companion of the Earth, to the Solar System they inhabit, works together in a breathtaking harmony. Paul Davies, one of the best known contemporary astrobiologists, describes this harmony in the words:
Everywhere we look in the Universe, from the far-flung galaxies to the deepest recesses of the atom, we encounter order. . . Central to the idea of a very special, orderly Universe is the concept of information. A highly structured system, displaying a great deal of organised activity, needs a lot of information to describe it. Alternatively, we may say that it contains much information. (Paul Davies, "Chance or Choice: Is the Universe an Accident?", New Scientist, vol. 80, 1978, p. 506)

This reveals a very obvious truth. The universe was created and is regulated and preserved through a sublime knowledge and power. And that sublime knowledge and power are those of Almighty Allah.

In the Qur’an, Allah reveals that the Earth and sky will be preserved while they are under His might:

“Allah keeps a firm hold on the heavens and Earth, preventing them from vanishing away. And if they vanished no one could then keep hold of them. Certainly He is Most Forbearing, Ever-Forgiving.”
(Surah Fatir: 41)


In this documentary we will be going on a journey to the Milky Way, some 10 million light years from the Earth, and from there to deep inside the atom, and will witness the magnificent order with which the universe was created. This is the universe we inhabit with all its glory…

1023 meters, 10 million light years.

The starting point of our journey…

We are 10 million light years from the Milky Way…

Thought of in terms of the vastness of space in general, the Milky Way is a very “small” place. It occupies barely a dot within it. Because there are other galaxies in space, some 300 billion according to the recent estimates! The Milky Way, visible from so far away, contains the Solar System, the planets, and the Earth we live on.

You, your home, the city you live in and even the planet you inhabit, the Sun that heats the planet and millions of stars like it, are all inside this dot you are looking at…

“He is the Originator of the heavens and earth. When He decides on something, He just says to it, ‘Be!’ and it is.” (Surat al-Baqara, 117)

1022 meters, 1 million light years.

We are 1 million light years from the Milky May that contains 250 billion stars like our Sun. There are billions of systems linked to the stars in this galaxy that resembles a swirl of white smoke. Yet we are so far away that the whole body looks like a simple, white cloud.

1021 meters, 100,000 light years.

If you look at the sky on a clear, cloudless night, you will see a belt of stars extending from one edge to the other. This mass of stars, which extends into deepest vastness of the sky and that revolves around its own axis at an amazing speed, is known as the Milky Way. Astrophysicists calculating this speed were unable to conceal their astonishment. Our galaxy, which completes a full circuit of its orbit every 250 million years, moves through the universe at an extraordinary speed.
