Allah would not have said in the Qur'an look into the vast kingdom of the Heavens if humans were uncapable of reaching it by any means.

Thinking carefully about the previous answer from the Qur'an might change some of the humanity's scientific concepts about the universe.

Supporting Notes: The following are gathered from different pages from this site mainly from the science page:

Q: When we look up we see one sky. Where did Allah create the Seven Heavens?
A: And We built above you powerful seven (heavens).
Translation of: Ayah 12, Surat AlNabe' in the Qur'an.

Q: Is Allah accessible to the angels? Note: Allah refers to ways among the Heavens. Has Science discovered ways that connect the galaxies?
A: A questioner asked about a forthcoming punishment; for the disbelievers there is no repellent for it; from Allah the Owner of the ways of ascent (in the seven Heavens); The angels and The Spirit (Gabriel = Jibrail) ascend towards Him in a day* which equals fifty thousand years (of human time).
* Day of Judgment.
Translation of: Ayat 1-4, Surat AlMa'arij.

Q: Where do angels live?
A: And how many angels in the heavens; their mediation will not be of any use but after Allah permits to whom He pleases and accepts. Yet those who do not believe in the Other World call the angels with female names. And they have no knowledge; But they follow assumption; And the assumption is of no use to the Truth.
Translation of: Ayat 26-28, Surat AlNajm.

Q: Is there one sky (Heaven)?
A: The seven Heavens (skies), the earth and all who is there declare His glory. All (created) things praise God but you don't understand their praise. God is Tolerant and Forgiving.
Translation of: Ayah 44 Surat AlIsra'.

Q: How did Allah create the Heavens?
A: Haven't you seen how Allah created seven Heavens (as) layers one above another; And He made the moon in them a Light and He made the sun* a Lamp.
Translation of: Ayat 15 -16. Surat Nooh.
* Said to be in the fourth Heaven.
Words: Kayfa = How, Sabe' = Seven, Samawat = Heavens, Tibaqa = Layers one above another, Ja'ala = He made, Qamar = Moon, Noor = Light, Siraj = Lamp.

Q: Do we have more than one place of sunset?
A: No! We created them from what they know (clay, sperm, soul); And I (Allah) do swear by (Myself) the God of The places of sunrise and the places of sunset (Allah is their God) that We (Allah) are capable to substitute better than them (disbelievers) and We will not be beat. So leave them to indulge in vain talk and to play about until they meet their Day that they were promised. The Day they will come out from the graves running as to idols they are rushing; Their eyesight is cast down, humiliation tires them out; That is the Day that they were promised.
Translation of: Ayat 39 - 44, Surat Nooh.

Q: In how much time did Allah make the earth and the heavens? And which was made first? (Note: Remember one year to Allah is a thousand years of human's time. Also remember that Allah's concepts such as time and space are different than humans' so do not ponder on the question 'how'.)
A: Say: You disbelieve in Who created the earth in two days and you make with Him equals; That is The God of all the worlds. And He made in it unshakable mountains from above it, and He blessed it and appraised in it its foodstuff in four days together (two days creation, two days foodstuff) for the seekers. Then He directed Himself towards the sky while it was smoke (Allah created it first as matter) and He said to it and to the earth: Come together (in proportion) willingly or by force. They said: We have come willingly. So He completed them into seven heavens in two days and He assigned in each heaven its business; And We decorated the lower heaven with lights and safeguarding (by guardian angels); That is the judgment of The All-Mighty, The All-Knowledgeable.
Translation of: Ayat 9 - 12, Surat Fusilat.

Q: Has Allah created the world according to a balanced mathematical order?
A: He lifted the sky and made the balance. Do not spoil the balance. Set the weight with justice and do not lose the balance.
Translation of: Ayat 7-9 Surat AlRahman.

Q: Has the Qur'an predicted man's travel into space?
A: You people of Aljin and human beings: If you can penetrate the zones of the heavens and the earth, do penetrate! You will not penetrate without authority (from Allah). So which sign of Allah do you deny? (Otherwise) a flame of fire and copper will be sent on you and you won't win. So which sign of Allah do you deny?
Translation of: Ayat 33-36 Surat AlRahman.

Q: Does the size of the land of the earth change?
A: Haven't they seen that We reduce the land of the earth from its sides. And Allah rules and there is no reviewer to His rule. And He is quick in judgment.
Translation of: Ayah 41 Surat AlRa'd.

Q: In pre-historic times, were the sky and the earth joined together?
A: Haven't those who don't believe in Allah thought that the heavens and the earth were joined together and We separated them. And We made from the water every creature alive, so why they can't have faith.
Translation of: Ayah 30 Surat AlAnbiya'.

Q: Will the history of the first creation be repeated?
A: The day We fold the sky like the folding of the book register. As We started the first creation We will repeat it. It is a promise We had undertaken that We are going to do it.
Translation of: Ayah 104 Surat AlAnbiya'.

Q: What can be the origin of the stones and the flames coming down from the sky?
A: For We decorated the lowest Heaven (sky) with the decoration of the constellations of stars; And as a protection from every rebellious Satan (devil); In order that they (Jinn) do not eaves-drop (secretly listen) to the Highest Assembly (of angels in the heaven) and they (devils) are hurled down (by stones) from every side; To cast them away and there is a permanent punishment for them; Only who caught a snatch (of the conversation) so a sharp flame followed him.
Translation of: Ayat 6 - 10 Surat AlSaffat.

Q: Which is more difficult to create: The Human being or the Sky?
A: Are you a more difficult creation or the sky He built? He lifted it very high and He smoothed it. And He darkened its night and brought out its day.
Translation of:Ayat 27-29 Surat AlNazi'at.

Q: Is there a discrepancy (disproportion) in the creation of space?
A: (Allah) Who created the seven heavens one above another. You will not see any discrepancy in the creation of The Most Merciful. Then return your vision do you see any crack? Again return your vision a second time your vision will come back to you chased away and regretful.
Translation of: Ayat 3-4 Surat AlMulk.

Q: Does the sky have pillars to support it?
A: He (Allah) created the heavens (skies) without pillars that you can see; And he set on the earth fasteners (mountains) to prevent the earth from shaking with you. And He scattered in it (earth) from every moving creature. And We (Allah) sent down from the sky water so We grew on it (earth) plants from every useful group. This is the creation of Allah, so show Me (Allah) what those other than Him (Allah) created?! Yet, the sinners are in a clear straying from The Right Path (of Allah).
Translation of: Ayat 10-11, Surat Luqman.

Q: Is human time put according to human capability to conceive time and limits?
A: Haven't they walk on earth so that they have hearts with which they can understand (faith) or ears with which they can listen! It is not that their eyes that become blind but their hearts that are in their chests that have become blind! And they ask you (Muhammad) to rush with the punishment (Day of Judgment); And Allah will not break His Promise; And a day according to your God is similar to one thousand years from what you count!

Q: Will there be an earthquake that will end the world?
A: O people! Fear your God; Indeed The Earthquake of The Hour (Day of Judgment) is a catastrophic thing. The day you see it (earthquake) distracting every breast-feeding mother away from whom she has breast-fed; And every pregnant woman will drop her pregnancy (miscarriage); And you will see the people drunk and they are not drunk; But the punishment of Allah is severe. And (yet) from the people who disputes in Allah, without knowledge and he follows every rebellious satan!
Translation of: Ayat 1 - 3, Surat AlHajj.

Q: Is the sun moving from its place? (On The Day of Judgment will the sun be nearer to earth than now?)
A: And the sun moves on to a resting place for it; That is the calculation of The All-Mighty and The All-Knowledgeable. And the moon We (Allah) have made it into stages until it returns (its shape) like the withered date (fruit) seed. The sun doesn't have the authority to catch up with the moon and the night is not outrunning the day; And every one floats in an orbit.
Translation of: Ayat 38 - 40, Surat Ya'seen.

Q: What will happen to the sun and the moon on The Day of Judgment?
A: But the human being wants to keep on sinning (in the time) ahead; He asks: When is The Day of Judgment? It is when the eyesight is lightened (flashed); And the moon eclipses (darkens); And the sun and the moon are grouped, the human being will ask that Day where is the way out? By no means! There is no refuge: To Your God that Day is the destination. The human being will be informed that Day about what he did and what he left. But the human being is acutely informed by his own self: And even if he makes his excuses!
Translation of: Ayat 5 - 15, Surat AlQiyamah.

Q: The earth is a part of a galaxy. Can earth vanish?
A: Allah does hold the heavens and the earth from vanishing; And if they (both) vanished, if there is someone who could have held them after Him! He has been The All-Tolerant, The Most-Forgiving.
Translation of: Ayah 41, Surat Fatir.

Q: Does Allah create things according to proportion (balance)?
A: Allah knows what every female bears (of pregnancy) and what the wombs lack (in time and number) and what they exceed; And everything with Him is according to proportion. The All-Knowing of The World of The Unseen and Witness, The All-Great, The Most-High (over others).
Translation of: Ayat 8 - 9, Surat AlR'd.

Q: Who will come on The Day of Judgment?
A: Are they (disbelievers) waiting until Allah comes to them in shades of clouds with the angels; and it is all over; and it is to Allah that the affairs will go back.
Translation of: Ayah 210, Surat AlBaqarah.

Q: Is the Day of Judgment coming soon?
A: They see it far away and We (Allah) see it coming soon. The Day when the sky will be like the melted metal, and the mountains will be like the coloured wool, and an intimate person will not ask about his intimate, (although) they will be put in sight of each other; the sinner desires if he could redeem (free) himself from the punishment of that day with his children, woman, brother and his family that shelters him and all those on earth so as to save himself. No! It is a pure flame of fire!.
Translation of: Ayat 6 - 15, Surat AlMa'arij.

Q: What will happen to the sky and the earth on The Day of Judgment?
A: When the sky will be split open and it listens to the command of its God and its obedience is fitting for it; and when the earth is flattened, and it throws out what is in it and becomes empty and listens to the command of its God and its obedience is fitting for it. O man! You are working hard towards Your God, and you will find your hard work (waiting for you). So the one who is given his book with his right hand, he will be judged for easily and he will return to his people happy. But who is given his book from behind his back, he will ask for grief, and he will enter Hell; He was happy among his people and he thought he will not return (to Allah). Yes! His God was watchful of him!
Translation of: Ayat 1 - 15, Surat AlInshiqaq.

Q: Who will be judged first on The Day of Judgment? (A scene of The Day of Judgment)
A: And it was blown in the Trumpet so whoever in the heavens and whoever on the earth fainted except whom Allah has willed; Then it was blown in it a second time and all of a sudden they were standing, looking; And the earth has shined with the light of Its God and The Book (record of deeds) was put; And the prophets and the martyrs have been brought forward; And it was judged among them with justice and they did not receive any injustice. And every soul was paid for what it did and He (Allah) knows better what they do.
Translation of: Ayat 68 - 70, Surat AlZumar.

Q: Why did Allah create the sky and the earth?
A: And We were not playing when We created the sky and the earth and what is between them. If We wanted to have fun We could have taken it from near Us if We were going to do it. But We hurl the truth onto the falsehood and it crushes its brain and it (falsehood) is bound to vanish. And you will have the severe punishment for what you attribute (to Allah).
Translation of: Ayat 17-18, Surat AlAnbiya'.

Q: How did Allah build the sky and the earth?
A: And We built the sky with power and We are capable. And We spread the earth and the best flatteners We are.
Translation of: Ayat 47-48 Surat AlThariyat.

Q: Some people say that the world manages itself. Is that true?
A: Every one on it (earth) will perish; And will remain the Face of Your God, The Sublime, The Noble; So which of the fovours of Your ( both humans and jinn) God do you deny?! Whoever is in the heavens and the earth asks Him; Every day He is in business; So which favour of your God do you deny?! We (Allah) will free (Ourselves) for you (on the Day of Judgment)! You the burdened (both humans and jinn); So which favour of your God do you deny?!
Translation of: Ayat 26 - 32, Surat AlRahman.

Q: What did Allah make in the sky?'.
A: And depend upon The All-Alive Who does not die and glorify His praise and enough for Him An Expert with the sins of his people; Who created the heavens and the earth and what is between them in six days then He sat firmly on The Throne; The Merciful do ask about Him an expert! And when it is said to them to prostrate to The Merciful they say: And what is The Merciful? Shall we prostrate to whom you (Muhammad) order us and it increases their rejection (of Truth). Blessed is He Who made in the sky constellations (of stars) and made in it light (Sun) and a shining moon. And He is Who made the night and the day followers of each other for whoever wants to mention God's name or wants to be grateful.
Translation of: Ayat 58 - 62, Surat AlFurqan.

Q: Did Allah bring the attention of any of the prophets towards the Heavens?
A: And this how We show Abraham (Ibraheem) the vast kingdom of the Heavens and the Earth.and so that he becomes from the convinced. So when the night became upon him dark he saw a star. He said: This is my god so when it set (went down ) he said: I do not like the setters. So when he saw the moon rising he said: This is my god. So when it set he said: If my God had not guided me I would have been from the straying people (away from The Right Path); So when he saw the sun rising he said: This is my god; This is bigger so when it set he said: O my people I am free from what you partner with (become polytheists); I have directed my face towards Who created the heavens and the earth: Believing in One God and I am not from the polytheists. And his people disputed with him. He said: Do you dispute with me in Allah and He has guided me! And I do not fear what you partner with unless my God wills something; My god has embraced everything with knowledge so will not you remember! And how do I fear what you have partnered with and you do not fear that you have made partners to Allah with what He has not sent down upon you an authority; So which team is worthier of the peace of mind if you were to know. Those who have faith and have not mixed their faith with transgression (sin) those for them is the peace of mind and those are the guided. And that was our argument We gave it to Abraham upon his people; We make higher in ranks whom We will; Indeed your God is Wise, Knowledgeable.
Translation of: Ayat 75 - 83, Surat AlAn'am.

Q: Who are the soldiers of Allah and where are they located?
Remember the angels convey Allah's messages, they record the deeds, bring punishment, guard the Heavens. They are the custodians of Hell and they do obediently whatever Allah tells them to do.
A: And Allah supports you (Muhammad) with a powerful support (angels). He (Allah) is Who sent down the peace of mind upon the hearts of the faithful so that they add faith to their faith; And to Allah belongs the soldiers of the Heavens and the Earth; And Allah has been All-Knowing, All-Wise.
Translation of: Ayat 3 - 4, Surat AlFat'h.

Q: How is the earth similar to the Seven Heavens?
A: Allah is Who created Seven Heavens and from the Earth like them*; The Command (of Allah) is (constantly) sent down among them so that you might know that Allah is upon everything capable and that Allah has surrounded everything with knowledge.
Translation of: Ayah 12, Surat AlTalaq.
* Needs more future research from humanity: The meaning is either that Our Earth is layered like the seven heavens. Or there are seven Earths as there are Seven Heavens.

Q: Why should man think beyond the surface when studying the existence of objects??
A: They know what is apparent from the Life of this World and they from the Other World are unaware (heedless). Haven't they thought in themselves that Allah did not create the Heavens and the earth and what is between them except for a True Reason* and a Limited Period and indeed a lot of people are rejecting as lies the Meeting with their God.
Translation of: Ayat 7 - 8, Surat AlRoum.
* To worship Allah.

Q: What can scientists learn from studying the Signs that indicate Allah's existence? And what does the sequence of the Signs mean?
Note: Remember the Qur'an is from Allah - The Most Wise in everthing. Even the sequence of the Qur'anic verses indicates a purpose.
Hint: What is a more difficult creation? What was created first?...etc.
A: The sending down of the Scripture (Qur'an) is from Allah - The AlMighty, The All-Wise. For in the Heavens and the earth there are certainly Signs for the believers; And in your (man's) creation and in what He (Allah) scatters* from creatures there are Signs for the people who are certain about their faith; And the alternation of the night and the day and what Allah had sent down from the sky from provision so He brought to life the earth after its death and the direction of the winds are signs for the people who understand; Those are the lines (verses) of Allah We (Allah) recite them to you (Muhammad) in truth so with which word after Allah and His lines will they have faith?!
Translation of: Ayat 2 - 6, Surat AlJasthiyah.

Q: What is behind the frightening sound of the wind during the severe weather which causes wide-spread damage?
A: (Allah swears) By those (angels) who line up in rows; And then the screamers with a sharp reprimand (reproof); And then the loud readers of the Warning: For your God is certainly One: The God of the Heavens and the earth and whatever is between them and the God of the points from where the sun rises.
Translation of: Ayat 1 - 5, Surat AlSaffat.

Q: Why does Allah mention the creation of the Earth and the Seven Heavens only. What about the billions of galaxies that humans spotted?
A: Taha; We have not sent down the Qur'an to make you suffer; Except (Quran) as a Reminder to whoever fears (Allah); Sent down from Who created the earth and the Lofty Heavens; The Most-Merciful upon The Throne established Himself Straight, To Him belongs whatever is in the Heavens and whatever is on earth and whatever is between them and whatever is under the soil (all levels of earth); And no matter you speak out loudly for He knows the secret and what is concealed; Allah has the Best Names.
Translation of: Ayat 1 - 8, Surat Taha.

Q: Again if humans can not see The Heavens why does Allah want us to look into them? (So Are the Seven Heavens and what we know as The Universe with its galaxies the same)
A: Say (order to Muhammad) Look into what is in the Heavens and the Earth! And what use are the Signs (of Allah's existence) and the Warnings for the people who do not believe (in Allah).
Translation of: Ayah 101, Surat Yunus.

Q: What was before the creation of the Heavens and the earth?
A: And He (Allah) is Who created the Heavens and the earth in six days and His Throne was (before their creation) over the water, (why they were created) in order to test you (people) which one of you is better in deeds and if you (Muhammad) say that you are going to be raised up after death those who disbelieved would certainly say: This (raising up) is (nothing) but manifest magic.
Translation of: Ayah 7, Surat Hood.

Q: Why did the Prophet Muhammad cry when a Qur'anic line about Allah's huge creation came down?
A: For in the creation of the Heavens and the earth and the alternation of night and day there are certainly miraculous signs (= Ayat) for those who understand; Those who remember Allah standing and sitting and when on their sides (lying) and they contemplate in the creation of the Heavens and the earth - (they say) Our God! You did not create this without purpose. Glory to You! So protect us against the punishment of the Fire (Hell).
Translation of: Ayat 190 -191, Surat AlImran.

Q: Allah created Seven Heavens as layers one above another (Line 15 Chapter Nooh). Which one is the Lowest Heaven?
Hint: Wherever the stars and the lights are located.
A: And We decorated the lowest Heaven with lamps (sources of light) and safeguarding (by guardian angels); That is the proportion of The AlMighty, The All-Knowing.
Translation of: Ayah 12, Surat Fusilat.
A: For We decorated the Lowest Heaven (sky) with the decoration of the constellations of stars.
Translation of: Ayah 6, Surat AlSaffat.
A: And We (Allah) decorated the Lowest Heaven (sky) with lights and We made it a place of stoning the Satans (evil Jinn) and We had prepared for them the Punishment of the Blazing Fire (Hell).
Translation of: Ayah 5, Surat AlMulk.

Q: Who is the God of what humans call "the universe"?
A: And to Allah belongs the (whole) Praise - the God of the Heavens, the God of the earth, the God of the inhabitants of all worlds.
Translation of: Ayah 36 , Surat AlJasthiyah.
