The Miraculous Nature of Water
We often assume everything expands when heated and contracts when cooled, but water defies this expectation. As it cools, it begins to expand, creating a phenomenon that has left scientists in awe.

#VALUE!
It's often said that miracles and nature are opposites. However, this natural phenomenon of water, frequently dubbed the 'miracle of water' by scientists, breaks that convention. Typically avoiding the term 'miracle,' scientists use it here without hesitation.
So, what exactly is happening?
We all know that materials expand in heat and contract in the cold. That's why railway tracks have gaps, to prevent buckling from heat expansion alongside train wheels. With rising temperatures, materials expand, increasing in volume, and when temperatures drop, they contract, decreasing in volume.
This fundamental law of nature governs all materials in the world without exception, as integral as it is to our understanding of the universe.
Yet astonishingly, water defies this rule. At a certain point, water stops 'obeying' nature's law and behaves in a completely contrary manner.
Between the temperatures of zero to four degrees Celsius, as water nears its freezing point, it ceases to contract. Surprise comes when water starts behaving as if it's being heated! It expands, and its volume continues to grow!
How does this happen?
Scientists have no explanation for why this occurs or what differentiates water from all other substances.
However, they understand well why this miraculous phenomenon exists. Without it, life would not exist on Earth. If water continued to contract upon reaching the freezing point, its volume decreasing like other materials, ice—which is heavier than water—would sink. If ice sank, groundwater in many parts of the world would form massive ice blocks, destroying aquatic life.
More so, without this miracle, the northern ice sea would freeze deep to its floor every winter, leaving vast areas as catastrophic ice blocks. In summer, these would melt, creating overwhelming streams that would flood continents, devastating their inhabitants.

Isn't this astounding?
Water is unique in that it must expand in cold to preserve life on Earth, contrary to the general law of nature.
Only water behaves this way, and only when following the law of nature would be detrimental to the world.
Scientists lack an explanation for this. However, as it is written: 'For He spoke, and it came to be; He commanded, and it stood firm' (Psalms 33:9).
He who created the world and established its natural laws also maintains the world He created. For Him, nature and miracles are one and the same, occurring at His will and command.
On water, there's more.
Many bodies of water are confined to various locations around Earth. Who will ensure they are transported to where they are needed, such as fields, or reservoirs running dry? Would transporting them rely only on artificial means, like national water carriers? In places without such infrastructure, are they doomed to desolation?
It turns out that huge quantities of water, totaling hundreds of thousands of tons, are frequently carried through the air to where they are needed. This happens through a special process turning heavy water into gas lighter than air, allowing it to ascend high—this new form is called clouds.
Another benefit of water evaporation is that murky, salty, or even polluted water becomes clear and sweet due to a natural law allowing only liquids to evaporate.
Additionally, a special mechanism using heat and cold changes worldwide creates air currents—called winds—that transport massive water quantities that evaporated over continents to the areas in need.
There, they transform back into liquid with cooling air and naturally fall under their weight.
In this way, water reaches everywhere, refilling depleted reservoirs, watering and growing crops, cleansing and refreshing.
Here's another marvel: have we noticed that raindrops fall gently, caressing the earth, not harming humans?
It's astonishing that despite their long aerial journey from cloud heights to the earth, raindrops don’t merge into a single torrent that could pound on us, reshape the ground, and wash away seeds and sprouts.
The wonder grows when, even during a strong wind, raindrops never collide but move as a unit diagonally together.
Who planned all this and made it successfully happen in reality?!
Without the miracle of water, there wouldn't be life on Earth! If water continued to contract upon freezing, ice—heavier than water—would naturally sink. If ice sank, many global aquifers would turn into huge ice blocks, killing all aquatic life.
More so, the northern sea would freeze solid to the bottom every winter, creating massive ice fields. In summer, these would melt and flood continents, drowning inhabitants.
Isn't it a magnificent wonder?
Water is the only material that must expand when cold, defying the universal law of nature.
Scientists can't explain how this occurs. But it is known: 'For He spoke, and it came to be; He commanded, and it stood firm' (Psalms 33:9).
The Creator of the world, who engraved the natural laws therein, also ensures the world He created perseveres. To Him, both nature and miracles are equal, occurring by His command and ordinance.
And more on water.
Huge amounts of water are concentrated around Earth, but who ensures their movement to where needed, like to sown fields or empty reservoirs? Would this only be through artificial methods like nationwide water carriers? Are desolate places marked by this absence?
Well, often, massive water amounts, totaling hundreds of thousands of tons, are carried aloft and reach where needed through a unique process turning heavy water into gas lighter than air, lifting them skyward. Their new name: clouds.
Another evaporation benefit is cloudy, salty, or even polluted waters becoming pure and drinkable by natural law allowing only liquids to evaporate.
Moreover, a special mechanism using heat and cold diversity worldwide creates air currents or 'winds' that transport evaporated water to needy areas.
There, they reconvert to liquid via air cooling, naturally descending by weight.
Thus, water is everywhere, replenishing drained reservoirs, watering and growing, washing and cleansing.
In a stunning marvel: raindrops fall gently and caress the earth rather than harm people.
Isn't it strange that, despite their long aerial journey, drops don't merge into a massive water wave pummeling down, changing ground faces, and washing out seeds and delicate sprouts?
The marvel intensifies as even strong winds don’t cause drop collisions, but the rain with all drops shift as one.
Who designed all and brought the plan into reality?!
