We all live on a huge ball which at high speeds is revolving, rotating and remains tilted, and we call it, the stable earth. The earth is about 4.5 billion years old. That is 45,000,000,000 years. The sun, the moon, the planets, and nearly everything in our solar system was formed at the same time, so they are all 4.5 billion years old.
The earth revolves round the sun very fast, more than one hundred thousand km per-hour. In other words, the earth revolves round itself one full rotation every day and revolves round the sun one full rotation every year
And you will see the mountains, which you deem so firm
Like clouds, they shall be in motion
A work of Allah, who has ordered all things to perfection
Surely, He is fully aware of all your action (Quran-27:88)
the verse talks about a worldly truth which is the movement of the mountains. It has been discovered that when we look at the earth from the outer space, the most important thing that distinguishes the earth is its high mountains that appear like small dots that revolve and move with high speed.
It also revolves along with the solar group round the center of the galaxy in more than 200 million years to complete one rotation. Let’s contemplate the following ratios concerning the rotations; a day, a year, 200 million years. What’s more is that the entire galaxy revolves in an enormous orbit whose end is known by no one except for Allah, the omniscient; Allah, the almighty says in the holy Qur’an:
The sun and the moon, follow a course, defined very clear (Quran-55:5)
It is not permitted to the Sun to catch up the Moon nor can the Night outstrip the Day
Each (just) is swimming in the sky (on their own way) (Quran-36:40)
The earth rotates (also called spins) on its axis at one thousand miles an hour; if it turned at one hundred miles an hour, our days and nights would be ten times as long as now, and the hot sun would then burn up our vegetation during each long day, while in the long night any surviving sprout would freeze.
Again, the sun, source of our life, has a surface temperature of 12,000 degrees Fahrenheit, and our earth is, just far enough away so that this ‘eternal fire” warms us just enough and not too much! If the sun gave off only one-half its present radiation, we would freeze, and if it gave half as much more, we would roast.
The circumference of (distance around) the earth is 2 x PI x radius, which turns out to be about 24,000 miles. Since the earth turns once per day (or 24 hours), that is 1,000 miles per hour! We don’t feel that because everything else is moving with us and because the motion is very, very smooth. It’s kind of like sitting in a car and reading a book or playing a game. If the car is going very smoothly, with no stops or bumps, and you don’t look out the window, you wouldn’t know you were moving. The only reason we know the earth is turning is because the sun and stars move across the sky.
Surely the creation of the earth and heaven
And in the day and night’s succession
There are signs very clear
For all those, endowed with insight who are (Quran-3:190)
The tilt of the earth is 23.45 degrees. This is measured as the tilt of the earth’s equator compared to its orbit around the sun. The amount of the tilt doesn’t change with time, but the direction that the earth’s poles are pointed does. This is called precession. It is just like the wobbling of a spinning top. The direction that the North Pole (and South Pole) is pointed moves in a circle in the sky very slowly, completing each circle once every 26,000 years.
The slant of the earth, tilted at an angle of 23 degrees, gives us our seasons; if it had not been so tilted, vapours from the ocean would move north and south, piling up for us continents of ice. If our moon was, say, only 50 thousand miles away instead of its actual distance, our tides would be so enormous that twice a day all continents would be submerged; even the mountains would soon be eroded away.
As you know, it’s hotter at the equator. This is because the sun shines down from almost overhead. At the North and South Poles, even when the sun is above the horizon so you can see it, its light is coming at an angle. This means that the sunlight is spread out over more area and it can’t warm the ground as much. So the poles are the coldest places on the earth.
We shall show these signs to them, in themselves and in the horizons
Till it is clear to them that true (are these revelations)
Does it not suffice that their Sustainer
To everything is witnessing over? (Quran-41:53)
If the crust of the earth had been only ten feet thicker, there would be no oxygen without which animal life must die. Had the ocean been a few feet deeper, carbon dioxide and oxygen would have been absorbed and no vegetable life could exist. Or if our atmosphere had been thinner, some of the meteors, now burned in space by the million every day would be striking all parts of the earth, starting fires everywhere.
Those who remember Allah while standing, sitting and lying down
And reflect on the creation of the earth and heavens
“Oh lord! You have not created this for vanity; your glory has no limit
Protect us from fire (of Gehannum’s) punishment” (Quran-3:191)
Because of these, and host of other examples, there is not one chance in millions that life on our planet is an accident.
